Well Andrew is slightly correct, if you want to find a percent of a whole number, you miltiply by the decimal version of the percent, so almost exactly how he did it. Except that he did not correctly make the percent into a decimal, you are supposed to move the decimal two spaces to the left so the correct multiplication would be 560x0.0075 which equals 4.2, which means that in reality, georgia is correct

X %  = x/100 as a fraction
so 0.75 % = 0.75 / 100  = 75/10000 or 0.0075

so 0.75% of 560  = 560 * 0.0075 = 4.2
George was correct.

An airplane travels at 150 miles per hour. The total distance traveled is 637.5 miles. Which equation should be solved to determ
OverLord2011 [107]
The distance (d) traveled by the airplane is the product of multiplying the speed (s) and the trip took (h). The equation is shown below, 
                                           d = s x h
Substitute the known values to the equation, 
                                       637.5 miles = (150 mile/ hour) x h
Manipulating the equation,
                                       h = (637.5 miles) / (150 mile/ hr) 
h is equal to 4.25 hours.

18. what is the midpoint of PQ P(-2, 2.5), Q(1.4, 4)​
scoray [572]

Mid point of the points PQ is (₋0.3 , 3.25)

Given points are:

P(₋2 , 2.5)

Q(1.4 , 4)

midpoint of PQ = ?

A location in the middle of a line connecting two points is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its endpoints. The line that connects these two places is split in half equally at the halfway.

The midpoint calculation is the same as averaging two numbers. As a result, by adding any two integers together and dividing by two, you may find the midpoint between them.

Midpoint formula (x,y) = (x₁ ₊ x₂/2 , y₁ ₊ y₂/2)

we have two points:

P(₋2,2.5) = (x₁,y₁)

Q(1.4,4) = (x₂,y₂)

Midpoint = (₋2 ₊ 1.4/2 , 2.5₊4/2)

= (₋0.6/2 , 6.5/2)

= (₋0.3 , 3.25)

Hence we determined the midpoint of PQ as (₋0.3 , 3.25)
