Answers

Answer 1

Answer:

Answer:

The painter spent 26 hours painting the house.

Step-by-step explanation:

If the painter charged $ 950 for painting a house, and he charges $ 35 per hour plus $ 40 for the ladder rental, in order to determine how many hours of work it took to paint the house, we must make the following calculation:

950 (total charge) - 40 (ladder rental) = Total work charge

910 (total charge per work) / 35 (charge per hour) = Total hours of work

910 / 35 = 26

It took 26 hours to the painter for painting the entire house.

Answer 2

Answer: the painter worked for 26 hours because 26*35=910+40 =950

The answer I get based off of the question is 1000.

An open box will be made from a rectangular piece of cardboard that is 8 in. by 10 in. The box will be cut on the dashed red lines, removing the corners, and then folded up on the dotted lines. What is the MAXIMUM possible volume for the box?A) 1.5 in3
B) 5.8 in3
C) 52 in3
D) 64 in3

Answers

The correct answer is this one: "C) 52 in3."

Given the illustration, we can be able to know the dimensions of the formed box.

The dimensions are
Length: 10 - 2x
Width: 8 - 2x
Height: x

So the volume is
Volume = (10-2x) * (8-2x) * (x)
Let x = 2.5
Volume = (5) * (3) * (2.5) = 37.5
Let x = 2
Volume = (6) * (4) * (2) = 48
Let x = 1.5
Volume = (7) * (5) * (1.5) = 52.5
Let x = 1
Volume = (8) * (6) * (1) = 48
Let x = 0.5
Volume = (9) * (7) * (.5) = 31.5

Answer:

Step-by-step explanation:

The height, width, and length of the box will be (x)(8 - 2x)(10 - 2x). The volume of the box will be 4x3 - 36x2 + 80x = 0 Use a graphing calculator to graph the polynomial. Use the maximum feature to see the greatest volume the box can have. Be sure to set your window accordingly and think about what constraints are on the box. The maximum volume for the box is 52 in3. The cut would be 1.5 inches long. This is where the graph crosses the x-axis.
