Answer:
69 hours
Step-by-step explanation:
The painter spends 3 hours working on a painting.
The sculptor spends 23 times as long as the painter.
The amount of time the sculptor spent is:
23 * 3 = 69 hours
The sculptor works for 69 hours.
Answer:
(4,5)
Step-by-step explanation:
The equation of the graph is y=x+1
Basically, if you plug in the x coordinate and add one, you will get the y coordinate.
This question is asking what the y coordinate would be if x is equal to 4
y=x+1
y=4+1
y=5
Therefore the ordered pair would be (4,5)
9) x= -7
10) x= 10
11) x= 5
12) x= 6
13) x= 4
14) x= -9
15) x= 3
16) x= 9
sorry it took so long! hope this helps!! :)
Answer:
The dimensions are 50 and 100 square foot
Step-by-step explanation:
Let x = length of fenced side parallel to the side that borders the playground
y = length of each of the other two fenced sides
Then, x + 2y = 200
<=> x = 200-2y
The Area = xy = y(200-2y)
The dimensions of the playground that will minimize the homeowner's total cost for materials when the area of the playground is maximum. He can cover more area but with the same cost.
The graph of the area function is a parabola opening downward.
The maximum area occurs when y = -200/[2(-2)] = 50
=> x = 100
So the dimensions are 50 and 100 square foot
