Answer:
h = 2
Step-by-step explanation:
7h = -(2h-18)
7h = -2h + 18
9h = 18
h = 18/9
h = 2
First find the mean (sum divided by number of values)
4+5+8+10+15=42
42/5=8.4
Then find the difference between each of the numbers and the mean.
4.4, 3.4, 0.4, 1.6, 6.6
Then find the mean of those values.
4.4+3.4+0.4+1.6+6.6=16.4
16.4/5=3.28
Final answer: 3.28
Answer:
86.5 square inches
Step-by-step explanation:
Area of circle: pi*r^2
10.5in /2= 5.25in
5.25^2=27.5625
27.5625*3.14=86.54625
rounded 86.5 in
Answer:
the other sides are 9 and 12
Step-by-step explanation:
use the Pythagorean theorem.
a^{2} +b^{2} =c^{2}
you know that c^2 is 225 because 15*15=225
a^{2} +b^{2} =225
(from here on I just plugged numbers in)
3:4=9:12
9^{2} +12^{2} =225
81+144=225
225=225
Yaaaaay!
