HURRY PLEASE Juan thinks that, on average, each math homework problem will take 3 minutes to
solve. He tells his parents that it will be more than 40 minutes before he is done with
math homework. If n stands for the number of problems, which inequality describes this
situation?
O A. n + 3 > 40
OB. n + 3 < 40
O C.
40 > 3n
OD
40 < 3n

help me with this please asap

If theoretical mass of CH3OH produced in the reaction below was 85.3grams, and the actual mass produced during the experiment was 80.1 gA. Calculate the percent yield of this reaction. B. Give one reason why the numbers are different. COfg) + 2 H2(g) -> CH;OH(I)

d

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
