Answer: width = 10 ft
Step-by-step explanation:
Area = length × width
Let l be length and w be width
l = w + 4 ........equation (1)
From above formula
140 = l × w. ........equation (2)
Substitute equation (1) into equation (2)
140 = (w+4) × w
w^2 + 4w= 140
w^2 + 4w - 140= 0
By factorization method
(w+14)(w-10)= 0
w=-14 or w= 10
So now width is 10 ft
From equation(1)
l=w+4
l= 10+4
l= 14 ft
Width = 10 ft and length = 14 ft
Answer:
$17.35/h
Step-by-step explanation:
In order to get the amount per hour he made, you first need to calculate the global amount of money he made.
He was paid $2,900 then he had costs of $1,200, that leaves him a net income of $1,700 ($2,900 - $1,200)
Then he worked a total of 98 hours for that money.
A salary is an amount of money expressed by a period of time. In this case, we'll use hours.
So, Jonah earned $1,700 after 98 hours of work:
S = $1,700 / 98 hours = $17.35/h
