4848 inches is how long the bike will be
Answer: x=-3 y=7.
Step-by-step explanation:


Answer:
40 days
Step-by-step explanation:
w1*h1*d1=w2*h2*d
15*8*20=10*6*d
2400=60d
d=2400/60
d=40
Answer: total length of frame material is 3.2 meters
Step-by-step explanation:
The perimeter of an object or a plane shape is the distance around the object of plane shape.
Mila plans to frame a poster she bought at a concert. The total length of frame material that she needs would be the perimeter of the rectangular frame. The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(length + width)
The frame will be rectangular with a base of 0.65 meters and a height of 0.95 meters. Therefore,
Perimeter = 2(0.65 + 0.95)
= 3.2 meters
Answer:
Step-by-step explanation:
Givem the profit function
p(x) = −2000x2 + 18000x − 15000
We are to generate the price range that will generate a monthly profit of at least $25,000
Substitute into the function we have;
25000 = −2000x2 + 18000x − 15000
Divide through by 1000
25 = -2x²+18x-15
Rearrange
-2x²+18x-15-25 = 0
2x²-18x+40 = 0
Divide through by 2
x²-9x+20 = 0
Factorize
x²-5x-4x+20 = 0
x(x-5)-4(x-5) = 0
x-4 = 0 and x-5 = 0
x = 4 and x = 5
Hence the price range that will generate a monthly profit of at least $25,000 is between $4 and $5 inclusive
