A truck uses 1 tablespoon of gasoline to drive 125 yards. How many miles can the vehicle travel per gallon?
Alborosie

Answer:

18.18 miles.

Step-by-step explanation:

A truck uses 1 tablespoon of gasoline to drive 125 yards.

Now, 1 gallon of gasoline contains 256 tablespoons of gasoline.

So, the truck uses 1 gallon i.e. 256 tablespoons of gasoline to drive (256 × 125) = 32000 yards.

Now, 1-mile distance contains 1760 yards.

Therefore, the truck uses 1 gallon of gasoline to drive \frac{32000}{1760} = 18.18 miles. (Answer)

What number is 5% of 46?
saveliy_v [14]
46 x 0.05, since 5% = 0.05 (5 / 100 = 0.05)

46 x 0.05 = 2.3


<span>7/12 is 58.33% </span>
<span>How do we change fractions to percents? </span>
<span>The steps are too simple. </span>

<span>First, divide the numerator (the number at the top of the fraction) by the denominator (the number below the fraction). </span>
<span>In the case above, 7 is the numerator and 12 is the denominator. </span>

<span>So, 7 ÷ 12 = 0.58333 </span>

<span>Then, multiply the result by 100. 0.5833 x 100= 58.33 </span>

<span>Finally, add the percent (%) sign to the result. </span>

<span>Therefore, 7/12 is 58.33%.  <span> </span></span>

The sign of the product of two integers with the same sign is positive. What is the sign of three integers with the same sign? E
Svetradugi [14.3K]
Can be both, because if all three were negative, it would be

negative*negative= positive
positive*negative=negative
example: -1*-1*-1=-1

but if all three were positive, it would obviously be positive, because any number of positives can't make negatives in multiplication.
