Answer:
x = 21
Step-by-step explanation:
For a pentagon, n = 5.
Each angle measures:
(n - 2)180/5 = (5 - 2)(180)/5 = 108
5x + 3 = 108
5x = 105
x = 21
Answer:
38.57 feets
Step-by-step explanation:
Given that:
Height of monument, h = 300ft
Shadow of monument, s = 210 ft
Shadow of tree, s = 27ft
Height of tree, = x
Using the relation :
Height / shadow = height / shadow
Monument = tree
300 / 210 = h / 27
Cross multiply
300 * 27 = 210 * h
8100 = 210h
h = 8100 / 210
h = 38.57 feets
The Volume of the Swimming pool is : 1161 cubic feet
The water in the 1 cubic yard = 202 gallons
Let us first change 1 cubic yard into 1 cubic feet
We know 1 yard = 3 foot
1 cubic yard = 3*3*3 cubic feet
1 cubic yard = 9 cubic feet .
Water in the 9 cubic feet = 202 gallons
water in the 1 cubic feet = 202/9 = 22.44 gallons
Let us suppose there is x gallon water in the swimming pool
so volume of the swimming pool in cubic feet * volume of the water in 1 cubic feet = x gallon
1161 * 22.44 = x
26058 gallons = x
Answer : 26058 gallons of water is required to fill the swimming pool .
Ashley's error is that she multiplied m by - 4.5, when she should be adding.
Hope this helps. - M
