Answer:
6.25%
Step-by-step explanation:
discount/ normal price
5/80
And we are trying to find out the percentage, so
x/100
Set the 2 equations equal to each other
5/80=x/100
Cross multiply
80x=500
Divide by 80 on both sides
x= 6.25
Is there anything else that goes with this question like a picture or something
Answer:

Max is 4 days.
Step-by-step explanation:
An inequality is a math statement with more the one solution. The solution has a range of values for which the inequality can be satisfied. It has the same following components as an equation: variables and operations. However, the equal sign is replaced by an inequality sign:
.
We start by choosing a variable for an unknown value. Here is it the number of days he rents the car. We choose d.
We know he rents it for $21 pr day or 21d for any number of days. We also know her will drive 250 miles at $0.10 per mile or 0.10(250). We will combine the two into an expression.
21d + 0.10(250)
We know his limit is $115. This means he can rent the car for any number of days until he reaches $115. The charge must be less than or equal to 115.
So we write
.
To find the number of days he can rent the car, we solve for d using inverse operations.

This means Jim can rent the car up to 4 days. The 5th day will put the cost over $115.

Now, If the exponent was negative like you asked....
Answer:
10 sides.
Step-by-step explanation:
In geometry, a decagon is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°. A self-intersecting regular decagon is known as a decagram.
