In 24 weeks Amanda earned $4,924 selling cars. She earns the same amount of money each week. Let “n” stand for the amount she earned each week. How much money does Amanda earn in one week?

explain how you got your answer 9basically put the work in the explanation

Answers

Answer:

Let's assume that Amanda earns the same amount of money each week, and we'll represent that amount as "n".

We are given that in 24 weeks, Amanda earned a total of $4,924. We can set up an equation to represent this information:

Total earnings = Amount earned per week * Number of weeks

$4,924 = n * 24

To find the amount Amanda earns in one week, we need to solve for "n". We can do this by dividing both sides of the equation by 24:

$4,924 / 24 = n

To calculate this, we can use a calculator or perform long division:

n ≈ $205.17

Therefore, Amanda earns approximately $205.17 in one week.

Hannah's hair was 18 inches long .Three years later it was 33 inches long. What was the percent increase,to the nearest hundredth, of Hannah's hair length?

Answers

Answer:

54%

Step-by-step explanation:

if you take 18 and divide it by 33 you would get 54

The 83.33 percent increase in Hannah's hair length.

What is the meaning of percentage?

A percentage is a number or ratio expressed as a fraction of 100.

Hannah's hair was 18 inches long

After three years,

it was 33 inches long

[tex]Difference\ (increase\ in\ length) = 33-18=15\ inches[/tex]

[tex]percent\ increase = \dfrac{Increase}{Original\ Number}\times100=\dfrac{15}{18}\times100=83.3333\\\\percent\ increase = 83.33 (nearest\ hundredth)[/tex]

Hence 83.33 % increase in Hannah's hair length after three years.

The measures of the angles of a triangle are shown in the figure below. Solve for x.
(8x-9)°
63°
70°

Answers

Answer:

x = 7

Step-by-step explanation:

(8x - 9)° = 180° - ( 70° + 63° )

8x - 9 = 47

8x = 47 + 9

x = 56 ÷ 8  

x = 7

Answer:

x=7

Step-by-step explanation:

63˚+70˚ = 133˚

180˚ - 133˚ = 47˚

(8x-9)˚ = 47˚

8x7=56

56-9=47˚

A block of cheese is in the shape of a rectangular prism with a width of 2.5 inches and a height of 5 inches. The volume of the block of cheese is 75 cubic inches. What is the length of the block of cheese?

Answers

Answer:

The formula for volume is l x w x h.

Step-by-step explanation

To find the missing link, we do the equation backwards.

l x 2.5 x 5 = 75

If we divide 75 by 5 then by 2.5, we get 6 which becomes our length.

To check, do 5 x 2.5 x 6 which should equal 75

6 is your length
