Area of one square = 2 x 2 = 4 square feet
4 square feet x 6 squares = 24 square feet total area
Answer: 24 square feet
Cosx = 0.5445
arccos(x) = 0.5445
x = 0.995
Answer:
13.5 minutes (13 minutes and 30 seconds)
Explanation:
In this problem, you are given the rate of which the water drips at which can be used to find the time of any amount of water that has dripped if using a ratio.
Drip rate: 3 min / 1 cup
If we set up a ratio, we can use X for the time it takes to waste 4 1/2 cups of water:
3 min / 1 cup = X min / 4 1/2 cups
Then, cross multiply to solve:
1*X=3*4 1/2
Simplify for the answer:
X= 13 1/2 minutes
(13 minutes and 30 seconds)
Answer: 15
Step-by-step explanation: all you have to do is multiply 2 1/2 by 3 which is 7.5 then you are going to multiply that by two then you will get 15 so it would take 15 hours to fill two tanks
2.25 + 8.50x = 50
8.50x = 50 - 2.25
8.50x = 47.75
——— ———
8.50. 8.50
x = 5.6 hours
Hope that helps :)
