Answer:
<u>553.143 mi²</u>
Step-by-step explanation:
Surface Area (Cylinder) :
- 2πr (r + h)
- 2 x 22/7 x 8 (8 + 3)
- 16 x 22/7 x 11
- 176 x 22/7
- 3872/7
- <u>553.143 mi²</u>
Answer:
$4,3750.00
Step-by-step explanation:
Simple interest is calculated using the equation:
I = Prt
I = Interest
P = Principal
r = Rate
t = Time (years)
I = 2,500 * 3.5 * 5
43750 = 2,500 * 3.5 * 5
Therefore, the interest is $43750.00
D=2n
.05n+.1d=3.5
I multiplied the nickels and dimes by these values because that is their actual monetary value
.05n=3.5-.1d
multiply everything by 20
n=70-2d
d/2=70-2d
.5d+2d=70
2.5d=70
d=28
n=14
so there are <u>28 dimes and 14 nickels
</u>checking this answer
28 dimes = $2.8
14 nickels = .70
2.8+.7=3.5
