Answer: $9.75
Step-by-step explanation: I think this is how you do it. 20h=195 so you divide 195 by 20 to find our how much he gets an hour.
Answer:
8/12 of fifth graders at Webster are enrolled in
art camp
Step-by-step explanation:
Question: At Webster Elementary School, 4/6 of the fifth graders are enrolled in summer camps. Of the students enrolled in summer camps, 8/12 are enrolled in an art camp. What fraction of the fifth graders at Webster are enrolled in art camp?
Given:
4/6 of the fifth graders are enrolled in summer camps.
8/12 are enrolled in an art camp.
fraction of the fifth graders enrolled in art camp:
find common denominator, 4/6 x 2/2 = 8/12
8/12 = 4/6 which means all went to art camp
The surface area is 188.4 m²
1.) First find the area of the circle.
A = πr²
A = 3.14 (3)²
A = 3.14 (9)
A = 28.26 m²
2.) Find the area of the other circle. We need to multiply the radius (3 m) by 2 to solve for the circumference.
3 * 2 = 6 m
3.) Now solve for the circumference of the second circle.
C = πd
C = 3.14 (6)
C = 18.84 m
4.) Find the area of the rectangle. The net of a cylinder includes two circles and a rectangle.
(The circumference that was solved was for us find the area of the rectangle. We only had 7 m for one of the dimensions of the rectangle.)
Now we have 18.84 m as the length of the rectangle and 7 m as the width.
A = lw
A = 18.84 (length) * 7 (width)
A = 131.88 m²
5.) Add the area of the circle two times with the area of the rectangle.
28.26 + 28.26 + 131.88 = 188.4 m²
I hope this helps. Im not good at explaining things, especially about math :’)
Answer:
B
Step-by-step explanation:
0.05(x + 8) + 0.10(x) = 2.50
dimes = x
nickels = x + 8
Therefore,
0.05(x + 8) + 0.10(x) = 2.50
0.05x + 0.40 + 0.10x = 2.50
0.15x = 2.10
x = 14
William has 14 dimes and 22 nickels in his pocket.
