Answer:
Step-by-step explanation:
We are given that
Length of roll of sod, l=3 feet
Width of roll of sod, b=1 feet
Length of courtyard, L=60 feet
Breadth of courtyard, B=50 feet
Area of rectangle=
Using the formula
Area of roll of sod=
Area of roll of sod=3 square feet
Area of courtyard=
square feet
Number of rolls of sod needed=
Using the formula
Number of rolls of sod needed=
Number of rolls of sod needed=
This is required expression which represents the number of rolls of sod needed.
Answer:
x = -5.39
Step-by-step explanation:
x + (−2.4) = −7.79
x = −7.79 + 2.4
x = -5.39
1564.894 grams
Hope this helps :)))
Answer:
(x) = 
Step-by-step explanation:
let y = f(x) and rearrange making x the subject
y = - 8x + 4 ( add 8x to both sides )
8x + y = 4 ( subtract y from both sides )
8x = 4 - y ( divide both sides by 8 )
x = 
Change y back into terms of x
(x) =
Answer:
1 hour = 7/18 of the distance between two ports
Step-by-step explanation:
Given that:
In 3/7 hours distance traveled is 1/6
For finding distance in one hour, divide both sides by 7/3 so that 3/7 would be cancelled out:
3/7 * 7/3 hours = 1/6 * 7/3 distance
By simplifying:
1 hour = 7/18 of the distance between two ports
This means that in one hour 7/18 of the distance is covered between two ports.
i hope it will help you!
