The spherical container has a radius of 4ft (where ft represents feet)
Its filled with gas that costs $12 per ft³
The value of gas in the container = ?
The volume of a sphere = 4/3
r³
The volume of the container = 4/3 × × 4³ ft³
One cubic foot = $12
4/3 × × 64 = How much?
Cross multiplying gives:
4/3 × ×64 × $12 = $3216.99 (Rounded up to nearest one cent)
Daniela made her error on step 3 because it says:
"Find the ratio of the differences of the means compared to the mean absolute deviation.
She didn't find the difference between the today and last week means. She just put the mean as a whole.
Answer:
90°
Step-by-step explanation:
angle on a straight line=180 and half of 180=90°
S = sisters ages
M =2S +7
M=13
13 = 2S+7
subtract 7 from each side
6 = 2S
divide by 2
3=S
sisters age is 3
