Answer:
1:8
Step-by-step explanation:
first cube's volume=2*2*2=8
second cube's volume=4*4*4=64
8/64=1/8
Answer:
-10/6=-1.7
Step-by-step explanation:
you need to do -6-4 over 6-4 then once you got your answer you see if it can be simplified to anything else and if it can that will be your answer.
Answer:
Step-by-step explanation:
T=4 1/4 hours
W=3 1/4 hours
T=7 1/4 hours
F=5 1/4 hours
add total hours
4.25+3.25+7.25+5.25=20 * 11
total for the week=$220
Step-by-step explanation:
You have to use logarithms.
1) a = log_3 (1/27) = -log_3 (27) = -3
2) b = log_3 (9 * 3^(1/2)) = log_3 (3 ^ {5/2}) = 5/2
3) c = -log_3 (sqrt3) = -1/2
Ok. In order to do this set up 2/5 divided by 5/7. The way you divide with fractions is by multiplying them but flipping the second fraction into 7/5 <---this is known as the reciprocal. In other words do:
2/5 x 7/5 =
14/25
There you go.
