Answer:
90 yards per minute
Step-by-step explanation:
Armen's time getting back was 36 -8 = 28 minutes. Then the ratio of times is 28/36 = 7/9.
The ratio of speeds is the inverse of this, so his speed coming back is ...
speed/70 = 9/7
Multiplying by 70 gives ...
speed = 70·9/7 = 90 . . . . yards per minute
Answer:
-7, -0
Step-by-step explanation:
(20 + 22 + 17) - 7 - 12 - (9 - x) = 37;
59 - 19 - 9 + x = 37;
31 + x = 37;
x = C) 6
The volume of a cube is s^3, where s is the length of a side.
If you have 84 cubes with sides of 1/3 in, the total volume is:
V=84(1/3)^3 in^3
V=84/27 in^3
V=28/9 in^3
V≈3.11 in^3 (to nearest hundredth of a cubic inch)
