5. x/15=n the quotient of a number
8. 8*x+3 3 plus the product of a number and 8
<u>Answer</u>
<span>(D) 14.2x0.784
<u>Explanation</u>
We do not have to multiply these number to tell the number of decimal places of the product.
The product of a set of number will have the sum of the decimal places of the factors. For example, in
</span>(A) 5.3478x6.4214 ⇒ 4+4= 8 decimal places
(B) 6.4x3.82 ⇒1+2= 3 decimal places<span>
(C) 521x3.82 </span>⇒ 0+2 = 2 decimal places. <span>
(D) 14.2x0.784</span> = 1+3= 4 decimal places.
the correct answer is (D) 14.2x0.784
<span>(1 gallon)/(20 miles) = (x gallons)/(180 miles)
1/20 = x/180
1*180 = 20x
180 = 20x
20x = 180
</span><span>x = 180/20
x = 9
It takes 9 gallons of gas to drive 180 miles
(9 gallons)*(3.98 dollars/1 gallon) = 9*3.98 dollars = 35.82
Round to the nearest dollar: 35.82 ---> 36
It costs $36 to travel 180 miles</span>
Just simply divide then multiply by 100
1/6= 0.166667×100=<span>16.6667%
So </span>16.6667% is the answer
if you want it rounded 16.7%
