Find the perimeter of the figure. Answer exactly or round to at least 2 decimal places.-width is 5 and height is 5
Answers
Let's start with the easy one: the square
The perimeter of a square = 4x where x = one side of the square
Since the width of the shape is 5, that means the other three sides of the square should also be five so:
perimeter of square = 4(5)
perimeter of square = 20 units
Now let's find the perimeter of the semicircle.
That equation is this:
perimeter of semicircle = 1/2(π x diameter) + diameter
We know that the width is 5 which means the diameter is 5.
Let's plug that in!
perimeter of semicircle = 1/2(π x 5) + 5
Multiplying pi by 5 and dividing it in half will give us a decimal, so we have to round that to the second place:
perimeter of semicircle = 1/2(5π) +5
perimeter of semicircle ≈ 7.85 + 5
perimeter of semicircle ≈ 12.85 units
Like we said at the beginning, this is two shapes in one so we have to add the perimeter of the square to the perimeter of the semicircle
perimeter of square = 20 units
perimeter of semicircle ≈ 12.85 units
20 + 12.85 = 32.85 units
So the perimeter of the shape = 32.85 units

A. 4.7 cm
Step-by-step explanation:
where the rectangles are similar, the ratios of the sides must be similar
Given that One has a length of 14 cm and a width of 9 cm, and the other has a width of 3 cm
let the length of the other rectangle be L
14/9 = L/3
L = (14 × 3)/9
= 14/3
= 4.66cm
≈ 4.7cm
The right option is A. 4.7 cm
Let's x the length of the second rectangle:
x/14=3/9==>x=14/3==>x=4.666666......

The aquarium holds 80 quarts of water.
We have,
In the United States customary system, there are 4 quarts in 1 gallon.
This conversion factor is a constant ratio that allows us to convert between gallons and quarts.
So, when we have 20 gallons of water, we can multiply it by the conversion factor of 4 quarts/gallon to find out how many quarts it is equivalent to:
20 gallons x 4 quarts/gallon = 80 quarts
Therefore,
The aquarium holds 80 quarts of water.
The conversion factor helps us determine the equivalent amount of one unit to another.
