10:18 and 15:27 because whenyou mutiply the numerator and denominatorby any number the answer would be equivalent to 5/9
Answer:
-1/3 is the slope perpendicular
Step-by-step explanation:
When we have 2 points, we can use the formula
m = (y2-y1)/(x2-x1) to find the slope
m = (1-7)/(3-5)
=-6/-2
=3
The slope is 3
We want a slope perpendicular
Remember that is the negative reciprocal
- (1/3)
-1/3
<span>Ok. You would set up the problem like this: 32/x=64/100 and then cross multiply; 3200=64x; divide both sides by 64; x=50. Mary has 50 customers.</span>
Given Information:
Distance = 160 miles
Required Information:
Rate = r = ?
Answer:
Rate = r = 20 mph
Step-by-step explanation:
Recall that the rate is given by
Rate = distance/time

It is given that the same trip would have taken 2 hours longer if he had decreased his speed by 4 mph.
Mathematically,

Simplify the equation

Now we are left with a quadratic equation.
We may solve the quadratic equation using the factorization method

So,

OR

Since rate cannot be negative, discard the negative value of r
Therefore, the rate is
