Answer:
176.71cm^2
Step-by-step explanation:
Area of a circle is pi*radius^2
your radius is given to you, which is 7.5
pi*7.5^2 in a calculator gives you 176.71
Answer:
$10,144.93
Step-by-step explanation:
Amount formula; A = (Principal* rate* time) +Principal
A= (P*r*t) +P
A= 14,000
r= 9.5% OR 0.095 as a decimal
t= 4
Plug the numbers into the formula;
14,000 = (P* 0.095 *4 ) +P
14,000 = 0.38P +P
14,000 = 1.38P
Divide both sides by 1.38 to solve for P;
14,000/1.38 = P
P= 10,144.9275
Therefore, the present value (Principal) = $10,144.93
Answer:
she made electronic calculating machines in order to calibrate rockets and make everything more precise
Step-by-step explanation:
I think starting from the top it would go as follows
9/36, 27/36, 32/36 , 4/36
b.) 9/36
c.) I really don't remember how to do the "order doesn't matter" thing anymore, so idk. my best idea is for you to look up the formulas for permutation and combinations. I know it has to do with that
