Answer:
Option B
Step-by-step explanation:
In order to find the answer to this question you need to use KCF and solve. Remember that negative times a positive equals a negative.
[tex]-\frac{3}{4} \div\frac{2}{8}[/tex]
Use KCF
[tex]-\frac{3}{4} \times\frac{8}{2}[/tex]
Multiply:
[tex]3 \times 8 =24[/tex]
[tex]4\times2=8[/tex]
Remember that negative times a positive equals a negative:
[tex]-\frac{24}{8}[/tex]
Simplify:
[tex]24\div8=3[/tex]
[tex]8\div8=1[/tex]
[tex]-\frac{3}{1} =-3[/tex]
[tex]=-3[/tex]

What slope is perpendicular to:
m = 5/8
The slope that is perpendicular to m = 5/8 is given by; m' = -8/5
When dealing with slope - intercept form of equation of a line, the general equation is;y = mx + c
where;
m is the slope
c is the y-intercept
Now, for a line to be perpendicular to a line above that has it's slope as m, the slope of this new line will be the negative inverse of the first slope. This is; m' = -1/mApplying that to our question, it means the slope that is perpendicular to m = 5/8 is; m' = -1/(5/8) = -8/5Read more at; https://brainly.com/question/21441448

Rita goes for a bike ride on a trail by her house. After 15 minutes of riding she sees a mile marker. When she reaches the third mile marker, she realizes that she has been biking for 30 minutes. What is the rate at which she is riding?
Given:
Rita covered 1 mile in 15 minutes.
She covered 3 miles in 30 minutes.
To find:
The rate at which she is riding.
Solution:
Let y be the number of miles covered in x minutes.
Rita covered 1 mile in 15 minutes. So, the point is (15,1).
She covered 3 miles in 30 minutes. So, the point is (30,3).
Slope of the line:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{3-1}{30-15}[/tex]
[tex]m=\dfrac{2}{15}[/tex]
Therefore, she is riding [tex]\dfrac{2}{15}[/tex] miles per minute.

Step-by-step explanation:
Answer:
40cm
Step-by-step explanation:
If you are converting 40cm to one inch and the conversion ratio is 2.54 : 1, you would place 40 in the numerator as the original ration has 2.54/1 as a fraction and the same will apply to 40cm.
** This applies if you are finding which number is in the numerator and not the answer to how much 40cm in inches is.
