Answer and Explanation:
Gina wanted to swim at the pool. She is allowed to spend at most $30. The cost to swim in the pool is 3 dollars per hour plus a flat fee of $3. How many hours can Gina swim without going over her spending limit?
This problem can be represented by .
'x' would be the number of hours. "At most" means less than or equal to. So, the value of x would have to be less than or equal to 30.
So, Gina would have a maximum of 9 hours to swim in the pool.
Hope this helps.
<h2>Hello!</h2>
The answers are:
Question 7:
154.29°
Question 8:
Yes, because the opposite sides are congruent.
<h2>Why?</h2>For question 7:
We know that the sum of all interior angles of any polygon is determined by the following formula:
Therefore the sum of all interior angles of a 14-gon is equal to 2160°, so, the measure of each interior angle is given by the following calculation:
Each interior angle is equal to:
For question 8:
We know that a quadrilateral is a parallelogram when the opposite sides are parallel or congruent.
From the statement we know that:
BE≅ED
and
AE≅EC
So, we can assume that the triangles formed by the sides BE and AE, and the sides EC and ED, are also congruent, meaning that the opposite sides BA and CD are congruent, so, the quadrilateral is a parallelogram.
Have a nice day!
