Answer:
Step-by-step explanation:
a^2 + b^2 = c^2
6 = b
c= 8
a=?
now u just replace
a^2 + 6^2 = 8^2
a^2 + 32 = 64
a ^2 = 64-32
a^2 = 32
a = 5.65685424949
if you rounded
a = 5,7
Answer: V≈565.49
Step-by-step explanation:
V=πr2h=π·62·5≈565.48668
I'm assuming you want help with numbers 7 and 8 because multiplication should be easy
so
7. rico average=15.5mph or 15.5/h
in 2.5 hours how far travel
15.5 in 1 hour
in 2 hours he will travel 2 times 15.5 miles
so in 2.5 hours he will travel 15.5 times 2.5 miles or 38.75
8. use estimation to show reasonable
15.5 can be rounded to 16
16 times 2 is 32
16 times 3 is 48
0.5 is half of 1 so the average is about the answer
(32+48)/2=80/2=40
he will travel about 40 miles (less since you rounded 15.5 up to 16)
so it is reasonable
Answer: $15
Suppose he can get $x
9/11.25=12/x
3/11.25=4/x
3x=45
x=15
