Answer:

c = 4

Step-by-step explanation:

In g(x)=cx-3 when x is set to 0.5 , g(x)= -1.

We can solve for "c" when it is the only variable in the equation.

Substitute x for 0.5 and g(x) for -1. Isolate "c" to solve by doing reverse operations.

g(x) = cx - 3

g(0.5) = 0.5c - 3    Substitute x=0.5

-1 = 0.5c - 3       Substitute g(0.5) = -1

-1 + 3 = 0.5c - 3 + 3     Add 3 to both sides to start isolating c

2 = 0.5c

2/0.5 = 0.5c/0.5      Divide both sides by 0.5 to isolate c

4 = c      Value of c

c = 4     Standard formatting puts the variable on the left side

Therefore the value of c if g(0.5)=-1 is 4.

Answer:

c = 4.

Step-by-step explanation:

Substitute the given values x = 0.5 and g(x) = -1:

-1 = c(0.5) - 3

0.5c = -1 + 3 = 2

c = 2/0.5

c = 4.

Answer:

The answer is 28 meters.

Step-by-Step Explanation:

Because the shape is a square, something times itself equals the area.

7 times 7 equals 49. Using this multiplication fact, and also using the fact that the shape is a square, 7+7+7+7=28.

And there you have it, a square with an area of 49 square meters has a perimeter of 28 meters.

The perimeter of the square with an area of 49 sq meters is 28 meters.

A square is a 2D figure of which all the sides are of equal length.

We know that area of a square is side multiplied by side.

Given the area of a square is 49 sq meters, So two same numbers that are multiplied by 49 are 7 and 7.

∴ The length of each side of the square is 7 meters.

We also know that the perimeter of a square is 4 times the length of the side.

∴ The perimeter of the given square is (4×7) = 28 meters.

Step-by-step explanation:

Answer:

In Diego’s pocket are worth $1.5.

Step-by-step explanation:

Given:

The coins in Diego’s pocket are worth 150% of a dollar.

Now, to find the worth in dollars in Diego's pocket.

So, as given the coins in Diego’s pocket are worth 150% of a dollar.

That means 150% of $1. As a dollar expresses 1$.

Thus, 150% of 1$.

[tex]=\frac{150}{100} \times 1[/tex]

[tex]=1.5\times 1[/tex]

[tex]=\$1.5.[/tex]

Therefore, in Diego’s pocket are worth $1.5.

Diego's coins are worth 150% of a dollar, which means they are worth $1.50. This was calculated by converting 150% to a decimal (1.50) and multiplying it by 1 dollar.

The question involves calculating the value of coins in terms of dollar amounts, which falls under the subject of Mathematics, specifically dealing with percentages and conversion of values.

Diego has coins in his pocket worth 150% of a dollar. To find out how much this is in dollars, we need to convert the percentage to a decimal by dividing by 100, which gives us 1.50. Therefore, the coins in Diego's pocket are worth $1.50. This is because 150% of 1 dollar is 1.5 times 1, which equals 1.5 or $1.50.

Remember, in math, percentages over 100% mean that you have more than the whole. So, 150% represents 1 whole (100%) plus half of another whole (50%), which in terms of dollars, translates to $1.50.

b = 15

c = 10

To Find:

∠A = ?

∠B = ?

a = ?

Solution:

IN Δ ABC,  Sine Rule says that

Answer:

Ron walked a total of 8 1/12 km

Step-by-step explanation:

Answer:

[tex]8\frac{1}{12} \; km[/tex]

Step-by-step explanation:

Distance walked by Ron on Monday = [tex]3\frac{3}{4} \; km[/tex]

Distance walked by Ron on Wednesday = [tex]4\frac{1}{3} \; km[/tex]

Now we will convert the given mixed fractions into improper fractions.

As we know that, a mixed fraction is composed of a whole number and a proper fraction.

Now,.

[tex]3\frac{3}{4} =\frac{3\times4+3}{4}=\frac{15}{4}[/tex]

[tex]4\frac{1}{3} =\frac{4\times3+1}{3} =\frac{13}{3}[/tex]

So, distance walked by Ron on Monday = [tex]\frac{15}{4}\; km[/tex]

Distance walked by Ron on Wednesday = [tex]\frac{13}{3} \; km[/tex]

Now, to find the total distance walked by Ron, we will add the distances walked by him on Monday and Wednesday.

So,

[tex]3\frac{3}{4} +4\frac{1}{3} =\frac{15}{4}+ \frac{13}{3}[/tex]

Now, we will find the LCM of the denominators of the given fractions.

The prime factorisation of 4 and 3 is,

4 = 2 × 2

3 = 3

So, LCM (3, 4) = 2 × 2 × 3 = 12

Now, we will convert each of the given fractions into their equivalent fractions with denominator 12.

[tex]\frac{15}{4}=\frac{15\times3}{4\times3}=\frac{45}{12}[/tex]

[tex]\frac{13}{3}=\frac{13\times4}{3\times4}=\frac{52}{12}[/tex]

So,

[tex]\frac{15}{4}+\frac{13}{3}=\frac{45}{12} +\frac{52}{12}=\frac{45+52}{12}=\frac{97}{12}[/tex]

Now, we will convert [tex]\frac{97}{12}[/tex] into improper fraction.

Now, 97 = 96 + 1 = 12 × 8 + 1

So, when '97' is divided by '12', then we get '8' as the quotient and '1' as the remainder.

So,

[tex]\frac{97}{12} = 8\frac{1}{12}[/tex]

Hence, Ron walked a total distance of [tex]8\frac{1}{12}[/tex] km in both the days.

The solution of the system is x=-1, y=-2

Step-by-step explanation:

we have

[tex]y=-2[/tex] ----> equation A

[tex]y=3x+1[/tex] ----> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both lines

using a graphing tool

The intersection point is (-1,-2)

see the attached figure

therefore

The solution of the system is x=-1, y=-2

For this case we have that by definition, the slope of a line is given by:

[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}[/tex]

Where:

[tex](x_ {1}, y_ {1})\ and\ (x_ {2}, y_ {2})[/tex]are two points through which the line passes.

According to the statement we have:

[tex](x_ {1}, y_ {1}) :( 10,1)\\(x_ {2}, y_ {2}) :( a, -5)\\m = \frac {1} {3}[/tex]

Substituting we have:

[tex]\frac {1} {3} = \frac {-5-1} {a-10}\\\frac {1} {3} = \frac {-6} {a-10}\\a-10 = \frac {-6} {\frac {1} {3}}\\a-10 = -18\\a = -18 + 10\\a = -8[/tex]

Thus, the value of a is -8.

Step-by-step explanation:

Given:

A recipe for ricotta cheese calls for 3/4 cup of whole milk for every 1/8 teaspoon of salt.

Now, to find the cup of whole milk should be used for every teaspoon of salt.

So, to get the cup of whole milk used we use unitary method:

For every 1/8 teaspoon of salt cup of whole milk used = 3/4 cup.

Thus for every teaspoon of salt cup of whole milk used = 3/4 ÷ 1/8.

[tex]=\frac{3}{4}\times \frac{8}{1}[/tex]  (changing the division to multiplication the fraction reciprocals.)

[tex]=\frac{24}{4}[/tex]

b) Scott will babysitting for 6 hours to have $51.00

Step-by-step explanation:

The given is:

Write an equation for the amount of money (m) Scott has after a number of hours babysitting (h) and find the number of hours of babysitting if Scott have $51.00

a)

∵ Scott has $15.00

∵ He earns $6.00 an hour babysitting

∵ h is the number of hours of babysitting

∵ m is the amount of money that Scott has after h hours

- Equate m by the sum of 15.00 and the product of 6.00 and h

∴ m = 15 + 6 (h)

∴ The equation is m = 15 + 6 h

The equation for the amount of money (m) Scott has after a number of hours babysitting (h) is m = 15 + 6 h

b)

∵ Scott has $51.00

∴ m = 51

- Substitute the value of m in the equation to find h

∵ 51 = 15 + 6 h

- Subtract 15.00 from both sides

∴ 36 = 6 h

- Divide both sides by 6

∴ 6 = h
