Answer:
114%
Step-by-step explanation:
okay, so we know he spent 22 minutes on math and 25.08 on spelling.
m=22
s=25.08
so to find a percent, you have to divide s/m
s/m= 25.08/22
s/m= 1.14
because this is a decimal, we have to convert it to a percent
114%
to check the answer, multiply 22 times 114%
the answer is 25.08, so we know we got the right answer.
She read 27 minutes already (90 x .30) and has 63 minutes 1 hour and 3 minutes left (90-27).
You use the volume formula for a sphere, or V=4/3*pi*r³;
so the first balloon (3cm) has a volume of 113.1.
The second balloon (6cm) has a volume of 904.78.
Therefore, you do 904.78-113.1, getting 791.68 cm³
