Answer:
15%
Step-by-step explanation:
The cost of 2 adults and 2 children without the discount is
2 adults = 2 (55) = 110
2 children = 2 (45) = 90
Total cost = 110+90 = 200
The original price is 200 and the new price is 170
Percentage discount = (Original price - new price)/ original price * 100%
= (200-170)/200 * 100%
= 30/200 * 100%
= .15 * 100%
= 15%
To find the area of a circle you do pi (3.14) multiplied by the radius squared.
The radius is half of the diameter: 11 / 2 = 5.5in
The radius squared is 5.5^2 = 30.25
Then take the squared radius and multiply that by pi 30.25 * 3.14 = 94.985
So the area of the circle is about 94. 99 in.

Answer:
h = -14
Step-by-step explanation:

d = 15
The swimmer swam 48 kilometres in 15 days.
STEP-BY-STEP EXPLANATION:
Let d = total no. of days the swimmer swam
Total no. of kilometres swam = 48

d = 48 / 3.2
d = 15
