Answer:
6. B
7. D
Step-by-step explanation:
For 6 found that the 56 pieces in the first bag was about 18% of that bag. So then I found that 18% of 450 is ruffly 84, so B
For 7 I multiplied 5x5 is 25 so then 50x5 is 250, which is D

Step-by-step explanation:
So the way to handle a problem like this is to rewrite the three numbers in terms of their relationship to one of the three numbers. Let's call the numbers x, y, and z, where x is the first number, y is the second, and z is the third.
We know x + y + z = 83.
Since the third number is twice the second, we say that z = 2y.
Since the second number is seven less than the first, we say that y = x - 7. We can rewrite this as x = y + 7.
Now all three can be written in terms of y.
x + y + z = 83
(y + 7) + y + 2y = 83
4y + 7 = 83
4y = 76
y = 19
The second number is 19. The first is 19 + 7 or 26, and the third is 2 times 19 or 38.
A check reveals that 26 + 19 + 38 = 83.
Answer:
h = 20 in
Step-by-step explanation:
V = pi * r^ * h
628 = pi x 10 x h
628/(pi x 10) = h
h = 20
