Johanna is selling cheese at the farmers’ market. One wheel of cheese has a diameter of 9 inches.
AleksAgata [21]

Answer:

The area of the wheel cheese is 63.62 inches²

The cost per square inch is $0.29

Step-by-step explanation:

* Lets explain how to solve the problem

- One wheel of cheese has a diameter of 9 inches

∵ The wheel is shaped a circle

∵ The diameter of the wheel is 9 inches

- The radius of the circle is half its diameter

∵ The radius of the wheel = 1/2 its diameter

∴ The radius of the wheel = 1/2 (9) = 4.5 inches

- The area of a circle = πr²

∴ The area of the wheel cheese = π(4.5)² = 63.61725124 inches²

* The area of the wheel cheese is 63.62 inches²

- The 9-inch wheel of cheese costs $18.60

∵ The area of the wheel cheese is 63.62 inches²

∵ It cost is $18.60

- To find the cost per square inch divide the cost of the wheel

  by its area

∴ The cost per square inch = 18.60 ÷ 63.62 = 0.29

∴ The cost per square inch is $0.29

Jacob plans to work at his family's restaurant this summer to make some extra money. His parents have agreed to pay him $9.75 pe
san4es73 [151]

Answer:

There is a direct relationship between the amount of money that Jacob earns and the number of hours he works.

Step-by-step explanation:

In math, a direct relationship exists when a change in one variable causes another variable to change in the same manner. E.g. if variable X increases, then variable Y will increase. If variable X decreases, then variable Y will decrease.

In this case, if Jacob works 25 hours per week, he will earn $243.75. If he works 30 hours, he will earn $292.50. But if he only works 20 hours, he will earn $195.

USING SIMILAR TRIANGLES IN INDIRECT MEASUREMENT If the shadow of a tree is 14 m long and the shadow of a person who is 1.8 m tal
maw [93]

Answer:

14/1.8 = x/4

Step-by-step explanation:

Using similar triangles,

height of man/length of man's shadow = height of tree/length of tree's shadow

1.8/4 = x/14

x/14 = 1.8/4

If we cross-multiply, we have

1.8 × 14 = x × 4

dividing both sides by 4 and 1.8,we have

14/4 = x/1.8

x/1.8 = 14/4

So, the two expressions we have are

x/14 = 1.8/4 and x/1.8 = 14/4.

So, the answer is 14/1.8 = x/4 since the product 1.8 × 14 = x × 4 cannot be expressed in the given ratio.
