4L + πr
Step-by-step explanation:
Since her yard is a square and half a circle, and she wants to fence the whole distance around the square and the half circle, then she needs to know the perimeter of a square and semicircle.
The perimeter of a square which is the distance around the square is given by 4L where L is the side length.
The perimeter of a circle, which is the circumference of a circle is 2πr, where r is the radius of the circle Therefore, half a circle would be 2πr/2 = πr
(b) The diameter of the semi-circle is 17 meters.
(c) To enclose the entire yard and keep Sprinkles from running away, the fencing needs to be 8.5π + 68 meters.
What is the perimeter?A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.
Given that Laura’s yard is in the shape of a square and a semi-circle.
The side of the square is 17 meters.
(b). To find the diameter of the semi-circle:
The diameter of the semi-circle = side length of a square.
The diameter of the semi-circle is 17 meters.
(c). To enclose the entire yard and keep Sprinkles from running away,
the total perimeter = the perimeter of the square + the perimeter of the semi-circle
= 4(17) + π(8.5)
= 8.5π + 68 meters
Therefore, the perimeter is 8.5π + 68 meters.

plus 79 =304 divided by 4 = 76
plus 89 =314 divided by 4 = 78.5
plus 91=316 divided by 4 = 79
so the answer is C

Answer:
91%
Step-by-step explanation:
(0.68 + 0.72 + 0.85 + x)/4 = 0.79
(2.25 + x)/4 = 0.79
0.5625 + 1/4x = 0.79

While on a plane, Charlie counted the number of adults, children, and empty seats. 1/5 of the seats were occupied by children.
3/4 of the seats were occupied by adults.
10 seats were empty .
A. How many passenger seats were on the plane
B. Write how you figured it out
Answer:
200 seats
Step-by-step explanation:
Let s = numbers of seats
1/5s = children
3/4 s = adults
10 = empty
The total number of seats = children + adults + empty
s = 1/5s + 3/4s + 10
Subtract 1/5s and 3/4s from each side
s -1/5s -3/4s= 1/5s-1/5s + 3/4s-3/4s + 10
s - 1/5s - 3/4s = 10
Get a common denominator
20s/20 - 4s/20 -15s/20 = 10
Combine like terms
1s/20 = 10
Multiply each side by 20
s/20 *20 = 20*10
s = 200
Answer:
19 seats
Step-by-step explanation:
you take the denominators: 5,4, and 9
then you add them to get 19.
