Answer:

We conclude that the value of k represented as a decimal rounded to the nearest tenth is:  k = 16.8

Step-by-step explanation:

Given the expression

\frac{5}{7}=\frac{12}{k}

We need to determine the value of k, represented as a decimal rounded to the nearest tenth.

Let us solve the expression

\frac{5}{7}=\frac{12}{k}

Apply cross-function multiply:   if \frac{a}{b}=\frac{c}{d}  then a\cdot \:d=b\cdot \:c

5k=7\cdot \:12

5k=84          ∵ 7 · 12= 84

Divide both sides by 5

\frac{5k}{5}=\frac{84}{5}

Simplify

k=\frac{84}{5}

k = 16.8    (Rounded to the nearest 0.1 or  the Tenths Place)

Therefore, we conclude that the value of k represented as a decimal rounded to the nearest tenth is:   k = 16.8

To avoid a storm, a passenger-jet pilot descended 0.38 mile in 0.4 minute. What was the plane's average change of altitude per m
Alenkinab [10]

Answer:

0.55 mile / minute

Step-by-step explanation:

The average change of altitude per minute would simply be the ratio of distance descended over time. That is:

average change of altitude = distance / time

average change of altitude = 0.44 mile / 0.8 minutes

average change of altitude = 0.55 mile / minute

22 is 44% of what number?
Mazyrski [523]
So 44% is 44/100
set it to 
22/x = 44/100
cross multiply 
(22* 100)/40 =  x
50 = x
so 
22 is 44% of 50

Hope this helps :)
