Answer:
It will increase by 0.2%.
Step-by-step explanation:
In this problem we need to solve for the monthly interest first.
We use the formula:
Now that we have the formula we now define our variables.
i = 20.87% or 0.2087
n = 12
or 23%
Now we have to find the daily interest rate.
or 23.20%
23.20% - 23% = 0.20% increase.
Answer:
you saved 15 bucks if you get the second one
Step-by-step explanation:
Well you have to start of by finding the circumference of the tire, which you can do with the equation 2πr. If the radius is 1.2 feet, you just plug this into the equation to get 2.4π, which we will round to 7.5. After 10 rotations, you should've traveled approximately 75 feet
The equations we get are
l = 6 + 2w (We get this from "The length of the rectangle is 6 more than 2 times the width.")
and
2l + 2w = 140 (We get this from the perimeter. Two times the length plus two times the width equals the perimeter of a quadrilateral.)
The first equation can be written as
l - 2w = 6
So now we have
2l + 2w = 140
l - 2w = 6
____________
Add the two equations.
We get 3l = 146
Divide by 3 on both sides.
l =
48
Your answer is
48.
