Answer:
Step-by-step explanation:
For this exercise you have to remember the Product of powers property, which states that:
Let be "x" the height in inches of a stack of pennies.
You know that the thickness of 1 pennie is , then, you can write the following proportion:
Solve for "x":
To express this height in Scientific notation the decimal point must be after the first digit, so you must move it one place to the left:
Radius of semi circles is 10 ft.
Area of semi circle is half the area of a normal circle.
Area of two semicircles: 1/2 * pi r^2 + 1/2 * pi r^2 = pi * r^2
So area of two semicircles with radius 10 ft = pi * 10^2 = 100 pi
Area of qtr circle: is quarter the area of a normal circle
Area of a quarter circle: 1/4 * pi r ^2
quarter circle has radius of 20 ft so area of it is 1/4 * pi * 20^2 = 100 pi
Total area = area of two semi + area of quarter
= 100pi + 100pi
= 200pi
≈ 628 ft²
Answer:
A)
Step-by-step explanation:
The starting balance is $35
after one game purchase, the balance is 35-1.75=33.25
after two game purchases, the balance is 35-(1.75*2)=31.50
The individual-size box of cereal is a rectangular prism with a volume of 44.625 inches³.
<h3>What is the volume of a rectangular prism?</h3>
The volume of rectangular prism of length l, width w and height h is given by:
V = lwh.
In this problem, the standard dimensions are:
- l = 3(1/2) = 3 + 0.5 = 3.5 inches.
- w = 8(1/2) = 8 + 0.5 = 8.5 inches.
The individual-size box has a 1/10 of the volume of the original box, hence:
V = 0.1 x 3.5 x 8.5 x 15 = 44.625 inches³.
