Answer:
He could work 10 hours as a lifeguard, and 5 hours as a tutor
Step-by-step explanation:
If he makes $16 an hour as a lifeguard
and $18 an hour as a tutor,
He could work 10 times $16, to make $160 for 10 hours.
Now we subtract this from $250, this makes $90.
We know need to find out how many times 18 goes into 90, 5 times.
So we know that he could work 10 hours as a lifeguard and 5 hours as a tutor.
I hope this is right.
I hope this helps too, have a nice day!
The indicated measure is:55⁰
To prove that thry are the circles diameters you can do it by two methods.One is calculating all the angles and the sum of all angles of it equals 360⁰.The one that is the opposite point of 55⁰ is 55⁰ so we need to find the other by : 180⁰-55⁰=125⁰. So 125⁰×2+55⁰×2=360⁰.
The second method is by knowing the rule that applies to diameters of a circle and that says that : a diameter is formed when a line goes from a point to the circle and passes the main point and then finishes to another point in the cirlcle.

Answer:
27%
Step-by-step explanation:
The total books sold were 182 and the amount of books sold that were nonfiction hardcover were 49 as represented in the frequency table.
To find the percentage we must divide the nonfiction hardcover by the total books.
49/182≈0.269 or 0.27
Multiply the decimal by a 100 to change it into a percentage, so our answer is 27%.
