Answer:
D 16% increase
Step-by-step explanation:
This is ez
just did this stuff in pre algebra
subtract 2 1/4 from 8 1/2
make fractions have same denominator
8 1/2 = 8 2/4
8 2/4 - 2 1/4 = 6 1/4 more pounds
9w + 5p
9(7)+5(4)
63+20
83
57 ft because drawing it up, we can make a right angled triangle with the right angle between the height of the man in the building and the distance out from the building of the man in the street, and the 35 degrees between the line connecting the man in the street with the man in the building, and the line out from the building of the man in the street. Then, tan of the 35 degree angle is = to opposite (40ft)/adjacent (to solve for). By cross multiplication, the A or adjacent (dist out from the building) = 40/0.7 (0.7 = tan of 35 degrees) so the answer is 57 ft.
69:
I know for a fact it can't be (B).
The answer is (A).
Reason: 6 times 9 is 54.
70:
13 is change to 15
13 plus 2 is 15
17 plus 2 is 19
I am 100% sure for question 69, but for question 70 im 100% unsure.
