Direct variation is of the form y=kx. We are given the point (8, -4) so we can solve for k, the constant of variation...
-4=8k, divide both sides by 8
-4/8=k
k=-0.5, so our equation is:
y=-0.5x,
Answer:
Divisible by 2, 5 AND 10.
Step-by-step explanation:
72590÷2=36295
72590÷5=14518
72590÷10=7259
The percentile rank for 10 will be 10th.
<h3>What is percentile rank?</h3>
The percentile rank of a particular score in statistics refers to the percentage of scores in the frequency distribution that are smaller than that score.
Percentile rank = [(Number of values below x) + 0.5]/ total number of values * 100
For 10,
Percentile rank = {[0 + 0.5]/5} x 100 = 10th
For 15,
Percentile rank = ([1 + 0.5]/5) x 100 = 30st
For 19,
Percentile rank = [2 + 0.5]/5 x 100 = 50th
For 23,
Percentile rank = [3 + 0.5]/5 x 100 = 70th
For 30,
Percentile rank = [4 + 0.5]/ 5 x 100 = 90th
The percentile rank for 10 will be 10th.

Answer:
Step-by-step explanation:
To do this there are many steps
Step 1: Turn the whole bathroom into a regular rectangle, so a 7.5x9.5 size bathroom or 71.25 sq ft.
Step 2: Figure out the area of the missing spaces
To do this you need to figure out the side lengths, so for the right tall side, its 7.5 and for the left its 6.5, there is a 4 and a 3, you take that and you can figure out the first spot in pink is .5x4=0.20 then the second one, you find the side length difference and thats the height (1) and then you know the width is 5 so 5x1=5 add those, 5+0.20= 5.20 and subtract that value from 71.25 to get her actual value, 66.05
I hope this helps, when i was writing the steps i decided it would be easier to write on the shape, so i am attaching that, I hope i helped you (:
