The answer to the factor expression is [tex]\frac{20}{3}[/tex]

Therefore [tex]12\frac{1}{3}-5\frac{2}{3}=\frac{20}{3}[/tex]

Step-by-step explanation:

Given that the factor expression is  [tex]12\frac{1}{3}-5\frac{2}{3}[/tex]

Now convert the mixed fraction into improper fraction as below :

[tex]12\frac{1}{3}-5\frac{2}{3}=\frac{37}{3}-\frac{17}{3}[/tex]

[tex]=\frac{37-17}{3}[/tex]

[tex]=\frac{20}{3}[/tex]

Therefore [tex]12\frac{1}{3}-5\frac{2}{3}=\frac{20}{3}[/tex]

The answer to the factor expression is [tex]\frac{20}{3}[/tex]

Answer: a = 22

Step-by-step explanation: First isolate a/3 by adding 7 to both sides of the equation. That gives you a/3 = 22.

From here since a is being divided by 3, multiply both sides of the equation by 3 so a = 66. We can check our answer by substituting a 66 back in for a in the original equation and we have [tex]\frac{66}{3} - 7 =15[/tex] or 22 - 7 = 15 or 15 = 15. Since this is a true statement, our answer checks.

Final answer:

The pencil is 11 centimeters shorter now than when it was new, which is determined by subtracting the current length (8 centimeters) from the original length (19 centimeters).

Explanation:

The subject of this question is Mathematics. The question involves calculating the length by which a pencil has become shorter, which is a basic arithmetic problem dealing with subtraction.

To find how much shorter the pencil is now compared to when it was new, we subtract the current length of the pencil from its original length. Given that the new pencil was 19 centimeters long and now measures 8 centimeters, the calculation would be:

Original length - Current length = Length difference

19 cm - 8 cm = 11 cm

Therefore, the pencil is 11 centimeters shorter now than when it was new.

The unit of measurement is particularly important here to provide clarity and accuracy to the measurement. For example, while measuring the length of a classroom, you might use meters or feet, but for small objects like a pencil, centimeters or inches are more appropriate.

Answer:

The value of the annuity in 10 years will be US$ 15,552.90

Step-by-step explanation:

Let's use the ordinary simple annuity formula to calculate the value of the annuity in 10 years, this way:

FV = Future value of an annuity stream

PMT = Dollar amount of each annuity payment  = US% 50

r = Interest rate = 3.5% compounded biweekly = 0.035/26

n = Number of periods in which payments will be made  = 26 * 10 = 260

FV = PMT * [(1 + r)ⁿ  − 1]/r

Now, replacing with the real values, we have:

FV = 50 *  [(1 + 0.035/26)²⁶⁰  − 1]/(0.035/26)

FV = 50 *  [(1.001346154)²⁶⁰  − 1]/0.001346154

FV = 50 * 0.41873217/0.001346154

FV = 50 * 311.058148

FV = 15,552.90

We only rounded the last product to the next cent, in all the other cases we used all the decimals for the calculations.

Answer:

  tan(F) = z/(2y)

Step-by-step explanation:

Make use of the similarity relationship to find the side necessary to compute the tangent. Then make use of the tangent definition.*

__

The two triangles are given as being similar. That means corresponding sides have the same ratios:

  EF/AC = ED/AB

  ED = AB·(EF/AC) = 4z(x/(8x)) = (4/8)z = z/2

The mnemonic SOH CAH TOA reminds you that the tangent relationship is ...

  Tan = Opposite/Adjacent

  tan(F) = ED/DF = (z/2)/y

  tan(F) = z/(2y)

_____

* Actually, you need to do this in reverse order: first you need to determine if you have all the necessary information to answer the question. You don't.

You need to know the length of side ED in terms of z. You notice that the corresponding side in similar triangle ABC has its length marked as a function of z, so all you need to find ED is the scale factor between the two triangles.

Since both hypotenuses are marked in terms of x, the scale factor is easily found.

The required simplified expression for 0.2(5x – 0.3) – 0.5(–1.1x + 4.2) is 1.55x - 2.16.

What is simplification ?

Simplification means reducing the expression in a simpler form using various operations. It eliminates unnecessary diversiry and variety.

The given expression is

0.2(5x – 0.3) – 0.5(–1.1x + 4.2)

or, 0.2 [5x + (–0.3)] + (–0.5)(–1.1x + 4.2) x – 2.16

Now,Let us expand the bracket-

0.2*5x - 0.2*0.3 - 0.5(-1.1x) - 0.5*4.2

Further,

x - 0.06 + 0.55x - 2.1

therefore,

x + 0.55x - 0.06 - 2.1

⇒ 1.55x - 2.16

Hence,the required simplified expression for 0.2(5x – 0.3) – 0.5(–1.1x + 4.2) is 1.55x - 2.16.

To find the value of the given function, substitute x = 12 instead of x and evaluate.

Given function:

[tex]\sf f(x)=\cfrac{2}{3} x+14[/tex]

Substitute 12 for x:

[tex]\sf f(12)=\cfrac{2}{3}\times12+14[/tex]

Convert 12 to a fraction to make multiplying easier:

[tex]\sf f(12)=\cfrac{2}{3}\times\cfrac{12}{1}+14[/tex]

[tex]\sf f(12)=\cfrac{2\times12}{3\times1}+14[/tex]

[tex]\sf f(12)=\cfrac{24}{3}[/tex]

[tex]\sf f(12)=8[/tex]

>>> Therefore, the value of the function is 8.

The value of  [tex]\( f(x) = \frac{2}{3}x + 14 \)[/tex] is 22.

To find the value of f(12), you simply need to substitute (x = 12) into the function f(x) and evaluate it:

Given: [tex]\( f(x) = \frac{2}{3}x + 14 \)[/tex]

Substituting x = 12:

[tex]\[ f(12) = \frac{2}{3} \times 12 + 14 \][/tex]

Now, let's calculate:

[tex]\[ f(12) = \frac{2}{3} \times 12 + 14 \]\[ = \frac{2}{3} \times 12 + 14 \]\[ = 8 + 14 \]\[ = 22 \][/tex]

So, [tex]\( f(12) = 22 \)[/tex].

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]

Let

y ----> the price

x ----> the weight

Find the value of the proportionality constant for each ordered pair in each table

[tex]k=\frac{y}{x}[/tex]

If all the values of k are equal, then the table represents a proportional relationship between the variable x and the variable y

Table 1

For x=1.5 lb, y=$4.50 ---->  [tex]k=\frac{4.5}{1.50}=3[/tex]

For x=2 lb, y=$9.00 ---->  [tex]k=\frac{9.00}{2}=4.5[/tex]

The values of k are different

therefore

The table not represent a proportional relationship

Table 2

For x=10 g, y=$0.50 ---->  [tex]k=\frac{0.50}{10}=0.05[/tex]

For x=15 g, y=$0.55 ---->  [tex]k=\frac{0.55}{15}=0.04[/tex]

The values of k are different

therefore

The table not represent a proportional relationship

Table 3

For x=0.5 Kg, y=$0.75 ---->  [tex]k=\frac{0.75}{0.5}=1.5[/tex]

For x=5 g, y=$7.50 ---->  [tex]k=\frac{7.50}{5}=1.5[/tex]

For x=2 lb, y=$4.00

Convert lb to oz

Remember that

1 lb=16 oz

so

2 lb=2(16)=32 oz

For x=32 lb, y=$4.00 ---->  [tex]k=\frac{4}{32}=0.125[/tex]

The maximum amount that the company X can borrow is $ 145,000

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Current ratio of assets/liabilities = 2.9

Current assets = $ 377,000

Current liabilities = Currents assets/Ratio = 377,000/2.9 = $ 130,000

2. The board of directors determines that the current ratio must never be below 2.6. What is the maximum amount that the company can borrow?

Desired ratio of assets/liabilities = 2.6

Current assets = $ 377,000

Desired liabilities = $ Current assets/Ratio = 377,000/2.6 = $ 145,000

The maximum amount that the company X can borrow is $ 145,000

The horse traveled 439.6 feet after walking around the track 5 times

Solution:

Given that, horse walks around a circular track while its trainer stands in the center

The trainer is 14 feet from the horse at all times

Therefore, radius of circular track = 14 feet

The circumference of circle is the distance traveled by horse for 1 lap

The circumference of circle is given as:

[tex]C = 2 \pi r[/tex]

Where, "r" is the radius and [tex]\pi[/tex] is a constant equal to 3.14

[tex]C = 2 \times 3.14 \times 14\\\\C = 87.92[/tex]

Thus the distance traveled by horse for one time in circular track is 87.92 feet

About how far had the horse traveled after walking around the track 5 times?

Multiply the circumference by 5

[tex]distance = 5 \times 87.92\\\\distance = 439.6[/tex]

Thus the horse traveled 439.6 feet after walking around the track 5 times

Since M and N are independent events, [tex]P(M)=P(M|N)=0.71[/tex]

Step-by-step explanation:

Two events A and B are said to be independent when the probability of A happening does not depend on whether B has happened or not.

In other word, this condition can be rewrite as follows:

[tex]P(A|B)=P(A)[/tex]

where

[tex]P(A|B)[/tex] is the probability of A happening  given that B has happened

[tex]P(A)[/tex] is the probability of A happening

In this problem, we have:

- M and N are independent events: so M does not depend on whether N occurs or not

Therefore,

[tex]P(M)=P(M|N)[/tex]

- Also, we know that

[tex]P(M|N)=0.71[/tex]

Therefore, it follows that

P.S: we have set [tex]b=0[/tex]  by default, because we are not given any information for it.

The line that represents a proportional relationship between y and x where the unit rate of change (or slope) is 0.4 can be plotted on a graph. Start from the origin and for each increase of 1 in x, y increases by 0.4. Plot these points and draw a straight line which represents this proportional relationship.

To graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to x is 0.4, you can start by creating a plot with an x- and y-axis. The y-axis represents the dependent variable and the x-axis represents the independent variable.

In this case, we're looking at a linear relationship, which means the line produced on the graph will be straight. This kind of straight-line graph typically uses the equation y = mx, where m is the slope (or unit rate of change) and x is the independent variable.

For this graph, the slope or unit rate of change is 0.4. This means that with every increase of 1 in x, y increases by 0.4. Plot some points on the graph starting from the origin (0,0). If x is 1, y will be 0.4 (1*0.4). If x is 2, y will be 0.8 (2*0.4). Keep plotting these points and connect them to draw the line. This line demonstrates the proportional relationship between x and y.
