Answer:
24^2
Step-by-step explanation:
Answer:
opposite angles in parralelograms are congruent
Step-by-step explanation:
F:m:s=4:5:7
s=f+18 and from above we see s/f=7/4 so s=7f/4 now we can say:
f+18=7f/4
4f+72=7f
3f=72
f=24 and we know s=f+18 so
s=42
m/s=5/7 so m=42*5/7=30
So Frank got 24, Mary got 30, and Seth got 42.
Answer:
12x-11
Step-by-step explanation:
There is no known solution, but this can be simplified. Add up all of the coefficients(# connected by the variable). Since after 7x is a - , the x following has to be negative. After adding the coefficients, you should have below, 12x. Then, you add up all of your constants.(# w/ no variable). Adding negative and positive, you should get below, -11. Finally, you should of simplified your equation to 12x-11.
Equation:
7x- (x-4)= 6x -7
<u>7x- (x</u>-4)= <u>6x</u> -7
12x
7x- (x-<u>4</u>)= 6x <u>-7</u>
-11
12x-11
12/7 = 20/x
12x = 140
x = 140/12 = 35/3 = 11.67
so radius of the large cone = 11.67 ft
Volume = 1/3 πr^2h
= 1/3(3.14)(11.67)^2(20)
= 2850.88
Answer is B. 2850.70 ft^3
