Answer:
A =5538.96 in^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We know the radius is 42 and pi is approximated by 3.14
A = 3.14 * 42^2
A =5538.96 in^2
Answer:
Dimes = x = 52
Nickels = y = 39
Step-by-step explanation:
Let
Dimes = x
Nickels = y
x + y = 91 (1)
0.10x + 0.05y = 7.15 (2)
From (1)
x = 91 - y
Substitute x = 91 - y into (2)
0.10x + 0.05y = 7.15
0.10(91 - y) + 0.05y = 7.15
9.10 - 0.10y + 0.05y = 7.15
- 0.10y + 0.05y = 7.15 - 9.10
-0.05y = -1.95
y = -1.95 / 0.05
= 39
Substitute y = 39 into (1)
x + y = 91
x + 39 = 91
x = 91 - 39
x = 52
Dimes = x = 52
Nickels = y = 39
Answer:
6296.5
Step-by-step explanation:
Cone volume: 622.0
Cylinder Volume: 5674.5
622+5674.5=6296.5
32 divided by 4 is 8. so 8 miles per gallon.
Answer:
? = 10
Step-by-step explanation:
Parallel lines divide transversals proportionally. The proportion can be written several ways. One is ...
?/6 = 25/15
? = 6(25/15) = 150/15 = 10
The missing length is 10.
