Answer:
y = 1/40x + 20
Step-by-step explanation:
Slope-intercept equation format:
y = mx + b
m = slope/ gradient/ constant of variation/ rate of change
b = y-intercept
To find the slope, use the formula:
Find two random points:
1 - (0.5, 40) , 2 - (1, 60)
Plug in:
Solve:
Divide:
The y-intercept is when the x-coordinate is equal to 0.
The y-intercept is always the beginning.
So observing the graph, the first point is (0, 20)
The x-coordinate is 0.
Y intercept = 20.
Plug in both slope and y-intercept:
y = 1/40x + 20
75% of 56 is .75 * 56
.75 * 56 = 42
Because you are decreasing, you subtract 42 from 56.
56 - 42 = 14
A 75% decrease of 56 books would leave 14 books.
Answer:
j. Pam, Tia, Veronica, Lily (if it's youngest to oldest)
Step-by-step explanation:
If Tia is 8 yrs old and she's 2 yrs older than Pam, then Pam must be 6 yrs old. Pam si 5 yrs younger than Veronica who must be 11 + 4 = 15.
Tia: 8 yrs.
Veronica: 11 yrs
Pam: 6 yrs.
Lily: 15
To make it simple make them all the same fraction
6/24 to trim 4/24 to style and she wants to work for 80/24 hours for 5 days
if each appointment she wants to take 6/24 to trim and 4/24 to style then every appointment will take 10/24 of an hour.
she wants to do 80/24 so she can do 8 appointments a day if each take 10/24
8 appointments a day 5 days a week
8x5= 40
Answer:
640
Step-by-step explanation:
8^2 = 64
10*64 = 640
