Answer:
Firstly find the area of the square and then the area of the two triangles and then plus it. That's what I think I tried
Answer:
Customer have to drive for 100 miles for the cost to be $140.
Step-by-step explanation:
Here, the cost of rest function is given as:
C = 120+.20 m
From above function, we can see that :
m = Number of miles traveled by the rent car
(1) The fixed rental charge of renting a car = $120
(2) The per mile rent of the car = $0.20
Now, C = $140
⇒140 = 120+.20 m
or 140 - 120 = 0.20 m
or, 0.20 m = 20
⇒ m = 20/0.20 = 100
or, m = 100
Hence, customer have to drive for 100 miles for the cost to be $140.
Answer:
(a-b) = -25
Step-by-step explanation:
(a+b) = -5
a*b=-150
So one of the letters have to be negative as you can only get a negative product from a positive and negative
There is probably a better way to do this, but I just plug in numbers that I think will work
So, (a*b) = -150, (-15*10) = -150
Okay that works so lets try the other one
(-15+10) = -5
This also works, so lets do the third one
(-15-10) = -25
Answer:
90 minutes or 1 1/2 hours
Step-by-step explanation:
30 minutes in 4 hours
4 goes into 12 3 times so then you would do 30×3 and get 90
