Answer:

Step-by-step explanation:

radius =( (8+7)^2 + (7+1)^2 )^1/2 = 17 unit

Equation of the circle = (x + 7)^2 + (y+1)^2 = 17^2

                                   = (-15+7)^2 + (y+1)^2  = 17^2

                                  =14

(-15, 14) lies on this circle

Zepler [3.9K]

Answer:

54 cheese pizzas

Step-by-step explanation:

We know that there are 120 pizzas in the freezer, and 45% of them are cheese pizzas.

We want to find out how many cheese pizzas are in the freezer, so we should multiply 45% and 120.

45% * 120

Convert 45 % to a decimal. Divide 45 by 100 or move the decimal place 2 spots to the left.

45/100= 0.45      or       45.0 --> 4.5 ---> 0.45

0.45 * 120

Multiply 0.45 and 120

54

54 cheese pizzas are in the freezer.

Ray bought a shirt on sale for $18.00. The original price was $24.00. What percent was the discount?
Sunny_sXe [5.5K]

Answer:

The discount would be 25%

Step-by-step explanation:

24 and 18 are both divisible by 6

24 is just 4×6

18 is just 3×6

This means that 18/24 is the same as 3/4

We calculate the discount by subtracting the percentage of the sale price from the original price.

3/4 is the same as 75% of 100% meaning the discount percentage is 100-75, which gives us 25%
