For this case we have the following variables:
x: number of months
f (x): number of caps sold
The function that models the problem is given by:
By the time the store sells 64 caps we have:
From here, we clear the number of months:
Answer:
the store sells 64 caps in 3 monts
A. month 3
hope that helped or not
Answer:
C
Step-by-step explanation:
We need to find the length of the red dotted line.
It is divided into 3 parts: the top, the middle slant, and the bottom
<u>The top</u>
Goes from y = 50 to y = 120, the length is:
120 - 50 = 70 units
<u>The bottom</u>
Goes from x = 60 to x = 120, the length is:
120 - 60 = 60 units
<u>The middle slant</u>
This is hypotenuse of the right triangle shown.
We will use Pythagorean Theorem to solve for this length, let it be x.
The theorem is:
Leg^2 + Another Leg^2 = x^2
One leg goes from x = 20 to x = 60, the length is 60 - 20 = 40
Another leg goes from y = 20 to y = 50, the lenth is 50 - 20 = 30
So, we have:
THe slant length is 50 units
TOtal fencing is: 70 + 60 + 50 = 180 units
1 unit is 3 feet, so
180 units * 3 = 540 feet
C is the correct answer
