Answer:
5
Step-by-step explanation:
5²=25 and 6²=36
25 is way closer to 27 than 36
so
5
Answer: 15
Step-by-step explanation:
=(−5−4)2+(−4−8)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√
d=(−5−4)2+(−4−8)2
=(−9)2+(−12)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾√
d=(−9)2+(−12)2
=81+144‾‾‾‾‾‾‾‾‾√
d=81+144
=2‾√25
d=225
=15
17+7 =25
1/5 = 0.20
3/4= 0.75
25 + 0.20 + 0.75
=25 + 0.95
= 25.95
I hope this helped a bit!:)
Answer:
Required of volume of tank = 39.62 m3 or 10471.18 gallons
Step-by-step explanation:
Total volume of water collected = Annual Rainfall * Useful Area
Total volume of water collected = 1199.87 * 1.1667
Total volume of water collected = 1399.89 ft3
---1 ft3 = 7.48 gallons
Hence, total volume of water collected in gallons = 1399.89 * 7.48 = 10471.178 gallons
----1 ft3 = 1/35.315 m3 = 0.0283 m3
Therefore total volume of water collected in m3 = 1399.89 * 0.0283 = 39.6169 m3
Workings
Useful area = 61% of 1967
Useful area = 0.61 * 1967
Useful area = 1199.87 sq/ft.
Annual rainfall = 14 inch = 14/12 month
Annual rainfall = 1.1667 ft.
Answer:
n = 32/7
Step-by-step explanation:
n/4 = 8/7
Using cross products to solve
n*7 = 4*8
7n = 32
Divide each side by 7
7n/7 = 32/7
n = 32/7
