Answer:
690 sq in
Step-by-step explanation:
SA = LA + 2B where LA is the lateral area and B is the area of the base
The triangular base has an area of
B = 1/2bh 1/2(5)(12) = 30
LA = ph where p is the perimeter of the base and h is the height of the prism
LA = (12 + 5 + 13)(21) = 30(21) = 630
SA = 630 + 2(30) = 630 + 60 = 690 sq in
FACTOR- 2(6x^2+5) and GCF is 2
Answer:
C) 960
Step-by-step explanation:
Let's expand the factorial.
n! = 1*2*3*4*...n
6! = 1*2*3*4*5*6
3!= 1*2*3
The given expression 
= 
Canceling out the common terms, we get
= 
= 8.4.5.6 [here . represents multiplication]
= 960
Answer: C) 960
Thank you.
Answer:
Look at the place after the tenths, it is more than 5.
99.999
So add +1 to the tenths place.
Rounded to the nearest tenth would be:
<h2>100.0</h2>
42. The mean is the total of the numbers divided by the amount of numbers. In this case the amount of numbers is 7 and the mean is 6. That means that the total of the numbers divided by 7 equals 6. To find the total you just do the opposite, multiply 7 by 6 and you get 42.
