The function H described by H(x) =2.75x+71.48 can be used to predict the height, in centimeters, of a woman whose humerus (the bone from the elbow to the shoulder) is x cm long.
Predict the height of a woman whose humerus is 39 cm long.

Answer:without the discount, it would have cost her $497

Step-by-step explanation:

Let x represent the amount that the gravel would have cost her without the discount.

Her brother works for the gravel company and got her a 28% discount. The value of the discount would be

28/100 × x = 0.28 × x = 0.28x

It mans that the amount that she paid for the gravel is

x - 0.28x = 0.72x

If Jamie paid $357.83 for the gravel (without tax), it means that

0.72x = 357.83

x = 357.83/0.72

x = 496.99

Approximately $497

Answer:

Step-by-step explanation:

When two triangles are similar, it means that the ratio of their corresponding sides is equal.

Therefore

96/(6x + 28) = 24/25

Crossmultiplying,

1) 96 × 25 = 24(6x + 28)

2400 = 144x + 672

144x = 2400 - 672 = 1728

x = 1728/144

x = 12

2) angle A and angle D is equal because they are alternate angles.

(2x + 6)/(x + 6) = 10/8

Crossmultiplying

8(2x + 6) = 10(x + 6)

16x + 48 = 10x + 60

16x - 10x = 60 - 48

6x = 12

x = 12/6 = 2

3) both triangles are right angle triangles. All angles are similar in both triangles. It also means that all the sides are similar. Therefore

45/30 = 40/x

Crossmultiplying

45 × x = 30 × 40

45x = 120

x = 120/45 = 26.7

Answer:

B

Step-by-step explanation:

This question is asking to make a conversion from kilolitres to liters.

There is a total of 1000L in 1kL.

Hence to make the conversion from KL to L , we have to multiply the KL by 1000. Hence, for 505KL, its equivalent measurement in L would be 505 * 1000 = 505,000

Hence, 505kL expressed in L is 505,000

Following steps and calculations, the missing coordinate r is -3. This point lies on line with slope of 2 along with other given point (4, -11).

Step-by-Step Calculation:

1. Identify the slope formula:

The slope (m) of a line passing through points (x1, y1) and (x2, y2) is calculated as:

m = (y2 - y1) / (x2 - x1)

2. Plug in known values:

We know the slope (m) is 2, points (x1, y1) are (4, -11), and points (x2, y2) are (8, r). Substitute these values:

2 = (r - (-11)) / (8 - 4)

3. Simplify the equation:

2 = (r + 11) / 4

2 × 4 = r + 11

8 = r + 11

4. Isolate r:

8 - 11 = r

r = -3

The value of missing coordinate "r" is -4

Solution:

Given that,

The points (1, r) and (4, -13) lie on a line with slope – 3

To find: missing coordinate r

The slope of a line is given by formula:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Where, "m" is the slope of line

Here in this sum,

m = -3

[tex](x_1, y_1) = (1, r)\\\\(x_2, y_2) = (4, -13)[/tex]

Substituting the values in formula,

[tex]-3 = \frac{-13-r}{4-1}\\\\-3=\frac{-13-r}{3}\\\\-9 = -13 - r\\\\r = -13+9\\\\r = -4[/tex]

Thus the value of missing coordinate "r" is -4

Answer: 0.25 or 25%

Step-by-step explanation:Women have two chromosomes XX and men have two also XY.

From the question, it can be seen that colorblindness is an X-linked recessive condition.

Let the X-linked recessive gene be specified as [tex]X^{-}[/tex] and the dominant gene which is not colorblind linked as [tex]X^{+}[/tex].

The question says the woman has a father who is colourblind which means her father possesses the X-linked recessive gene [tex]X^{-}[/tex] which means he has chromosomes [tex]X^{-}Y[/tex] and therefore must have given his daughter the recessive gene

For her husband who has normal vision his chromosomes will be [tex]X^{+} Y[/tex].

So, the probability that their son will be colourblind will be;

Chromosomes [tex]X^{+}[/tex] Y

[tex]X^{+}[/tex] [tex]X^{+} X^{+}[/tex] [tex]X^{+}Y[/tex].

[tex]X^{-}[/tex] [tex]X^{-} X^{+}[/tex]. [tex]X^{-}Y[/tex].

Therefore, the probability that their son will be color blind = ¼ or 0.25 or 25%

Answer:

A. Stereo Store Job is highest paying Job.

B. The Difference between the weekly salaries of these two jobs is $45.

Step-by-step explanation:

Given:

Annual Pay of job in stereo store =  34.6K

Now K here means (1000).

So we can say that;

Annual Pay of job in stereo store = [tex]\$34.6\times 1000= \$34600[/tex]

Also Given:

Weekly salary of Job at clothing store = $620

We need to find which job is the higher-paying job.

Also We need to find the difference in the weekly salaries of these two jobs

Solution:

First we will find the weekly salary of  job in stereo store.

Now we know that there are 52 weeks in a year.

So weekly salary of  job in stereo store can be calculated by Annual Pay of job in stereo store divided by total number of weeks.

framing in equation form we get;

weekly salary of  job in stereo store = [tex]\frac{34600}{52}=\$665.38[/tex]

Now we see that weekly salary of  job in stereo store is greater than Weekly salary of Job at clothing store.

Hence Stereo Store Job is highest paying Job.

Now we need to find the  difference in the weekly salaries of these two jobs.

difference in the weekly salaries can be calculated by weekly salary of  job in stereo store minus weekly salary of  job in clothing store.

framing in equation form we get;

Difference = [tex]\$665.38-\$620 =\$45.38[/tex]

Rounding to nearest dollar we get;

Difference = $45

Hence the Difference between the weekly salaries of these two jobs is $45.

A. The job in the clothing store is the higher-paying job. B. The difference in the weekly salaries of these two jobs is $45.

To determine which job is higher-paying, we need to compare the annual salaries of both jobs and convert them to weekly salaries for a fair comparison, assuming a standard work year of 52 weeks.

A. Comparing the annual salaries:

1. The job at the stereo store pays $34,600 per year. To find the weekly salary, we divide this amount by 52 weeks:

[tex]\[ \frac{34,600}{52} = 665.38 \][/tex]

So, the weekly salary for the job at the stereo store is approximately $665.38.

2. The job at the clothing store pays a weekly salary of $620.

Now, comparing the weekly salaries:

Stereo store: $665.38 per week

Clothing store: $620 per week

The job at the clothing store pays more per week than the job at the stereo store.

B. Calculating the difference in weekly salaries:

To find the difference between the weekly salaries of the two jobs, we subtract the weekly salary of the stereo store job from the weekly salary of the clothing store job:

[tex]\[ 665.38 - 620 = 45.38 \][/tex]

Rounding to the nearest dollar, the difference in the weekly salaries is approximately $45.

However, the question asks for the difference in the weekly salaries of these two jobs, not the difference in the weekly salary of the stereo store job from the clothing store job. Since the clothing store job pays more, we should actually subtract the weekly salary of the clothing store job from the weekly salary of the stereo store job to find the additional amount the clothing store job pays per week:

[tex]\[ 620 - 665.38 = -45.38 \][/tex]

Since we are looking for a positive difference, we take the absolute value:

[tex]\[ |-45.38| = 45.38 \][/tex]

Rounding to the nearest dollar, the difference in the weekly salaries of these two jobs is approximately $45. However, it seems there was a mistake in the initial answer provided for part B. Let's correct this:

The correct calculation for the difference in weekly salaries is:

[tex]\[ 665.38 - 620 = 45.38 \][/tex]

Rounding to the nearest dollar, the difference is $45.

Answer: the cost of riding the taxi for 8 miles is $9

Final answer:

To find the sine of angle ABC, we need to first find the length of the arc BC, which is equal to the circumference of the resulting cylinder. The circumference can be found by multiplying the diameter of the rhombus, which is equal to the length of side AB, by π (pi). In this case, the circumference is 6π. Using the length of the arc, BC, and the radius of the cylinder, we can find the angle ABC using the formula θ = s/r, where θ is the angle in radians, s is the length of the arc, and r is the radius of the cylinder.

Explanation:

To find the sine of angle ABC, we need to first find the length of the arc BC, which is equal to the circumference of the resulting cylinder. The circumference can be found by multiplying the diameter of the rhombus, which is equal to the length of side AB, by π (pi). In this case, the circumference is 6π. Since the volume of the cylinder is given as 6, we can use the formula V = πr^2h to find the height of the cylinder. Plugging in the values, we get 6 = πr^2h. Since the radius of the cylinder is half the length of side AB, which is 3, we can solve for h to find that h = 4/π. Using the length of the arc, BC, and the radius of the cylinder, we can find the angle ABC using the formula θ = s/r, where θ is the angle in radians, s is the length of the arc, and r is the radius of the cylinder. Plugging in the values, we get θ = 6π/3 = 2π.

Answer:the amount that the bookstore pay the publisher for the book is $64.4

Step-by-step explanation:

Let x represent the amount that the bookstore pay the publisher for the book.

The college bookstore marks up the price that it pays the publisher for a book by 35%. This means that the value of the mark up would be

35/100 × x = 0.35 × x = 0.35x

Therefore, the amount that the bookstore is selling the book would be

x + 0.35x = 1.35x

If the selling price of a book is $ 87.00, then it means that

1.35x = 87

x = 87/1.35 = 64.4

5+b/a+2 c/a+20+6 b/a -2 c/a=0

7 b/a+25=0

b/a=-25/7

from (1)

5-25/7+2 c/a=0

2 c/a+10/7=0

2 c/a=-10/7

c/a=-5/7

so eq. of circle is x²+y²-25/7 x-5/7 y=0

7(x²+y²)-25 x-5 y=0

[tex]y=1x+16[/tex]

Step-by-step explanation:

Two given points are (3,19)  and (7,23)

f(x)=mx+b

slope is m  and b is the y intercept

[tex]slope m =\frac{y_2-y_1}{x_2-x_1} =\frac{23-19}{7-3} =1[/tex]

slope m= 1  (3,19) is (x1,y1)

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-19=1(x-3)[/tex]

[tex]y-19=1x-3[/tex]

Add 19 on both sides

[tex]y=1x+16[/tex]

Final answer:

The linear function rule for the line passing through the points (3, 19) and (7, 23) is found by calculating the slope (which is 1) and using the point-slope form to derive the slope-intercept form y = x + 16.

Explanation:

To write a linear function rule for a line that passes through the points (3, 19) and (7, 23), we need to calculate the slope of the line and use the point-slope form to write the equation.

Finding the Slope (m)

Using the formula for the slope m = (y2 - y1) / (x2 - x1):

m = (23 - 19) / (7 - 3) = 4 / 4 = 1

We can use the point-slope form y - y1 = m(x - x1), where (x1, y1) is a point on the line:

y - 19 = 1(x - 3)

Simplifying this equation to the slope-intercept form (y = mx + b), we get:

y = 1x + 16

Therefore, the linear function rule in terms of x and y for this line is y = x + 16.

Answer:

46 jumps

Step-by-step explanation:

Since the grasshopper is two inches long, and can jump a distance of 40 inches, then its jump ratio is 2:40 = 1:20.

The athlete's body-length is 5 feet 9 inches. We convert this to inches which is 5 × 12 = 60 inches. We then add the remaining 9 inches to make it 60 + 9 = 69 inches. Since our jump ratio for the grasshopper equals that for the athlete, 1:20 = 69: 20 × 69= 69 : 1380. Thus the athlete's jump ratio is 69 inches to 1380 inches.

The athlete wants to cover one mile and we know that 1 mile = 63360 inches. So, we divide the distance the athlete wants to cover(1 mile = 63360 inches) by his jump-length(1380 inches) to get the number of jumps it takes to cover a mile. Number of jumps × jump-length of athlete = one mile, so Number of jumps = one mile/jump-length of athlete = 63360 inches/ 1380 inches= 45.9 jumps ≈ 46 jumps.

It would take the athlete approximately 46 jumps to cover one mile.

To solve this problem, we'll start by establishing the jumping ratio of the grasshopper and then applying that ratio to the athlete to determine how many jumps it would take for the athlete to cover one mile.

First, let's calculate the jump ratio for the grasshopper:

- Grasshopper's length: 2 inches

- Grasshopper's jump length: 40 inches

The ratio of the grasshopper's jump length to its body length is:

[tex]\[ \text{Jump ratio} = \frac{40 \text{ inches}}{2 \text{ inches}} = 20 \][/tex]

Next, let's find the athlete's height in inches:

- Athlete's height: 5 feet 9 inches

- 1 foot = 12 inches

Thus, the athlete's height in inches is:

[tex]\[ 5 \text{ feet} \times 12 \text{ inches/foot} + 9 \text{ inches} = 60 \text{ inches} + 9 \text{ inches} = 69 \text{ inches} \][/tex]

Using the grasshopper's jump ratio, we can determine the distance the athlete could jump:

[tex]\[ \text{Athlete's jump length} = 69 \text{ inches} \times 20 = 1380 \text{ inches} \][/tex]

Now, we need to determine the total number of jumps the athlete would need to cover one mile. First, convert one mile to inches:

- 1 mile = 5280 feet

- 1 foot = 12 inches

Therefore, the distance of one mile in inches is:

[tex]\[ 5280 \text{ feet} \times 12 \text{ inches/foot} = 63360 \text{ inches} \][/tex]

Finally, the number of jumps required for the athlete to cover this distance is:

[tex]\[ \text{Number of jumps} = \frac{63360 \text{ inches}}{1380 \text{ inches/jump}} \][/tex]

Calculating this value:

[tex]\[ \text{Number of jumps} \approx \frac{63360}{1380} \approx 45.92 \][/tex]

Since the number of jumps must be a whole number, we round 45.92 to the nearest whole number:

[tex]\[ \text{Number of jumps} \approx 46 \][/tex]

Therefore, it would take the athlete approximately 46 jumps to cover one mile.

Answer:

The chef uses 5452.8 grams of butter each day.

Step-by-step explanation:

Given:

Chef use 12 pounds of butter each day.

To find the amount of butter in grams used by chef each day.

Conversion units:

1 pound = 16 ounces

1 ounce = 28.4 grams

Solution:

We need to convert 12 pounds of butter in grams of butter.

We will apply unitary method to carry out the conversion.

If 1 pound  =  16 ounces

Then, 12 pounds = [tex]12\ pounds\times\frac{16\ ounces}{1\ pound}= 192\ ounces[/tex]

If 1 ounce = 28.4 grams

Then, 192 ounces = [tex]192\ ounces \times \frac{28.4\ grams}{1\ ounce} = 5452.8\ grams[/tex]

Thus, the chef uses 5452.8 grams of butter each day.

Final answer:

convert 12 pounds to ounces (192 ounces) and then multiply by 28.4 to convert ounces to grams, resulting in 5452.8 grams of butter used per day.

Explanation:

To find out how many grams of butter the chef uses each day, we need to convert pounds to ounces and then ounces to grams.

First, we use the conversion factor that there are 16 ounces in a pound. So, for 12 pounds of butter:
