Answer:
y4 i hope thiss helps
Step-by-step explanation:
Height of the truck =m 162 inches
Height of the bridge under which vehicles pass = 12 feet 5 inches
= (12 * 12) + 5 inches
= 144 + 5 inches
= 149 inches
We arrived at the above deduction from the fact that 1 feet is equal to 12 inches.
Now
Difference in height of the truck and the bridge is = 162 - 149 inches
= 13 inches
So the truck is 13 inches taller than the maximum height of the bridge. The correct option among all the options that are given in the question is the second option or option "B". I hope it helps you
Answer:
x=5 1/4
Step-by-step explanation:
2 1/4= 
---> divided by 3 to find 1/7x----> 
=1/7x---> x=21/4---> x=5 1/4
The value of y when x= 2401 is -10
<h3>How to determine the value of x?</h3>
An inverse variation is represented as:
Where k is the proportionality constant
When y = -70, x = 49
So, we have:
Take the square root of 49
Multiply through by 7
k = -490
Substitute k = -490 in
When x =2401, we have
Evaluate the square root
Divide
y = -10
Hence, the value of y when x= 2401 is -10

Revenue = 7.5x - 100
Operation Costs = 5.8x + 79.86
To break even, operation cost = Revenue
⇒ 7.5x - 100 = 5.8x + 79.86
7.5x = 5.8x + 179.86 (Add 100 to both sides)
7.5x - 5.8x = 179.86
1.7x = 179.86
x = 105.8
This implies that the company will need to sell at least 106 items to make a profit.
The inequality that will determine the number of items at need to be sold to make a profit is x ≥ 106
The solution to the inequality is as follows
Revenue = 7.5x - 100
if x =106
Revenue = 7.5(106) - 100
Revenue = 695
Operational Cost = 5.8x + 79.86
if x = 106
Operational Cost = 5.8(106) + 79.86
Operational Cost = 694.66
Profit ≥ (695 - 694.66)
Profit ≥ 0.34
The company must sell at least 106 items to make a profit.
