Answer:
110
Step-by-step explanation:
He said he had atleast 1 of each. Hope it helps.
The function f(t) that describes this scenario will be A = -42.57t + 1399.28
- Let the amount of oil remaining after time t be A
- Let the time taken be "t"
This required linear expression will be given as A= mt + b
Writing the gallons of oil and the time taken as a coordinate point (A, t), these are given as (11, 931) and (18, 633)
m is the rate of change = 633-931/18-11
m = -298/7
m = -42.57
Get the intercept;
633 = -42.57(18) + b
633 = -766.29 + b
b = 1,399.28
Heence the function f(t) that describes this scenario will be A = -42.57t + 1399.28

Angle 45
Because it could be 45,45,90
5+3a = 3-2a
So
5a = -2
a=-2/5=-0.4
It would be A or B
but not D,C
