Since it’s a 2% error it can be 2% less or greater than 60% so h hours are between 58% and 62%.
Answer:
in the lowest terms.
Step-by-step explanation:
Here, the given expression is : 
Solving the given expression, we get:

Now, to express the fraction into lowest terms
18 = 2 x 3 x 3, 44 = 2 x 2 x 11
So, 
Hence,
in the lowest terms.
Answer:

Step-by-step explanation:
The equation given is:

We take d's to one side and others to another side of the equal sign. Thus,

<u>Note:</u> remembering to change signs when changing sides
Now, we want to isolate d on the RHS:

To make "d" the subject, we divide both sides by "m+6", to get our answer:

This is the answer.
Answer:
shaded area = 538 mi²
Step-by-step explanation:
area of bottom rectangle = 14 * 8 = 112 mi²
area of middle rectangle = 7 * ( 5 + 8 + 30) = 301 mi²
area of the upper rectangle = 5 * 25 = 125 mi²
Total shaded area = 125 mi² + 301 mi² + 112 mi²
= 538 mi²
