Determine which solution is correct or incorrect
The solutions are not given. So, I will provide a general explanation
The amount (n) is calculated as:
So, we have:
The above is the general equation to solve for the amount, given h hours
When h = 2.5, we have:
Answer:
(for # 3) 7
Step-by-step explanation:
because the whole thing = 128 4/7 degrees and there are seven sections that equal 51 3/7 degrees. when added they equal 128 4/7
Based on the length and width of the rectangular lawn, and the percentage the man has mowed, the strip width would be 40.5 m.
<h3>what is the width of the strip mowed already?</h3>
first, find the area of the lawn:
= 100 x 200
= 20,000 ft²
the area mowed is:
= 40.5% x 20,000
= 8,100 ft²
the width is therefore:
= 8,100 / 200
= 40.5 m

7932 x 56 = 444192 and since it’s asking you to multiply by .56 and 793.2, just move the decimal over to the left three places in your answer since there’s three digits after the decimals in your factors. so you get 444.192
Answer:
A) A = X^2 + 11X + 24
B) X = 18 ft
C) 414 ft^2
D) 132 ft^2
Step-by-step explanation:
A) Width W of yard and path = X + 3
Lenght L of path = X + 5 + 3 = X + 8 ft, therefore,
Area of yard and path = L x W = (X +3) x (X +8)
A = X^2 + 11X + 24
B) if area of the yard and path is 546 ft^2,
546 = X^2 + 11X + 24
X^2 +115X - 522 = 0 (quadratic equation)
Solving the quadratic equation gives
X = 18 and X = -29
Our answer can only be positive so we choose X = 18 ft
C) lenght of yard = 5 + 18 = 23 ft
Width = 18 ft
Therefore area = L x W = 23 x 18 = 414 ft^2
D) area of path = area of path and yard minus area of yard
= 546 - 414 = 132 ft^2
