A. 21*(2/3) = 14 -----> not 3/2 (X
B. 7*(2/3) = 14/3 ----> not 14 (X
C. 21*(2/3) = 14 -----> equal 14 (O
D. 28*(2/3) = 56/4 -> not 42 (X
E. 42*(2/3) = 28 ----> equal 28 (O
F. 14*(2/3) = 28/3 --> not 21 (X
so the answer is C and E
Answer:
Step-by-step explanation:
33×10^-3 is equivalent to 33/1000, or 0.033.
This, in turn, is equivalent to 3.3×10^(-2) (which is in scientific notation)
Hey download photomath it works great u take a picture of your math problem and itll give u the steps n the answer
18 2/5 = 92/5 = 18.4 as a decimal;
16m/s * 8s = 128m Multiply out the time to get the total displacement from the descent.
128m-71m = 57m Find the displacement from the descent to the ascent and then add that to 1364m to get your answer.
1421m
