Answer:
Step-by-step explanation:
Recall that the volume of a whole sphere is given by the formula:
then, the volume of a semi-sphere would be half of the formula above:
Now, the radius R is given by half of the semi-sphere diameter: 15/2 = 7.5 cm.
which makes our calculation:
The inequality would start out looking like this:
Now it's just a matter of solving the inequalities simultaneously. Get rid of the fraction by multiplying everything by 9:
Then distribute the 5 into the parenthesis:
Now add 160 everywhere:
and finally divide everything by 5:
-22<F<266
Each foot of the real desk will be 0.5 on the dolls desk.
3ft x 0.5 in per ft = 1.5 inches
30 x 16? if thats what your asking then the answer is 480
so.. to get every angle, simply plug in 10 for "x" for each.
