We know that
[surface area of sphere]=4πr²
[surface area of hemisphere]=2πr²
(sphere)
r=12 in
[surface area of sphere ]=4π12²--------> 576π in²
(hemisphere)
r=12 in[surface area of hemisphere ]=2π12²--------> 288π in²
[the ratio of the surface area of sphere to the surface area of hemisphere]
=576π/288π-------> 2
the answer is
the ratio is 2
Answer:
8793
Step-by-step explanation:
9×1013= 9117
3×108=324
9117-324= 8793
This is the equations,
Tee Company: 9.65x + 43
Shirtz Company: 8.40x + 58
If you were to buy one shirt from each company these would be the prices,
Tee Company: $52.65
Shirtz Company: $66.40
I would recommend the Tee Company since the price per shirt is cheaper.
Answer:
Step-by-step explanation:
Let
x -----> the number of slabs of butter
y ----> the number of cups of butter
we know that
The ratio is
so
That means-----> The number of slabs of butter must be equal to the number of cups of butter
In this problem
we have
Remember that
so
The number of slabs of butter needed must be equal to the number of cups of butter
therefore
Answer:
Step-by-step explanation:
Let the required volume be x
<u>Use the ratio of gallon/volume to solve:</u>
- 1/0.13 = 20/x
- x = 20*0.13
- x = 2.6 ft³
With 20 gallons the scientist can cover 2.6 ft³ of water volume
