Answer:
(A)
Step-by-step explanation:
Let y be the length of the rectangular backyard and then according to the question, y should be atleast 150 ft, then the possible inequality is:
and the distance around should be no more than 450ft, then the possible inequality is:
Then, the shaded region (green) is the possible dimensions of the backyard.
Step-by-step explanation:
Let:
x=length
(x/4)+1=width
P=2l+2w
62=2x + 2[(x/4)+1]
62=2x + 1/2x + 2
multiply both sides by 2
124=4x+x+4
5×=120
x=24
length: 24 inches
width: 7 inches
hope this helps!!
Answer:
x²+1
Step-by-step explanation:

x²+1
Answer:
- The car makes a complete revolution in 12 s.
Step-by-step explanation:
The table header tells you the distances are <em>feet</em> (not yards). The maximum height is 55 feet, and the lowest point is 5 feet. The difference between these values is the diameter of the wheel, 50 feet, so the radius is 25 feet.
The wheel goes from its highest point to its highest point in 15 -3 = 12 seconds, so that is the time required for a complete revolution.
Just substitute 10 for x in <span>g(x)=-3x+1: g(10) = -3(10) + 1 = -29 (answer)</span>
