Answer:
B
Step-by-step explanation:
Volume = Volume of cylinder + Volume of semi sphere
= pi*r^2*h+(2/3)*pi*r^3
=pi*(4*12+16/3)=pi*53.3
Answer:
(-1,-4)
Step-by-step explanation:
6m-5n=14 equation 1
2m+2n= -10 equation 2
using equation 2 we have
2m=-10-2n
m=-5-n equation 3
using equation 1 we have
6*(-5-n)-5n=14
-30-6n-5n=14
-11n=14+30
-11n=44
n=-44/11
n=-4
using equation 3
m=-5-n
m=-5-(-4)
m=-1
finally we have
(-1,-4)
Answer:
20% decrease.
Step-by-step explanation:
difference over original
50.97-40.78= 10.19
diff/orig=sales tax
10.19 / 50.97= 19.99..
19.99 is approximately 20.
Answer and Explanation:
Gina wanted to swim at the pool. She is allowed to spend at most $30. The cost to swim in the pool is 3 dollars per hour plus a flat fee of $3. How many hours can Gina swim without going over her spending limit?
This problem can be represented by
.
'x' would be the number of hours. "At most" means less than or equal to. So, the value of x would have to be less than or equal to 30.

So, Gina would have a maximum of 9 hours to swim in the pool.
Hope this helps.
