Step-by-step explanation:

108 cm² cardboard will be needed to make this design.

As per the given data:

The shape of the box is a triangular prism, and all the dimensions are given in the diagram.

A polyhedron with two triangular bases and three rectangular sides is referred to as a triangular prism. It is a three-dimensional form with two base faces, three side faces, and connections between them at the edges.

To find the cardboard that will be needed to make this design:

= Total surface area of the triangular prism.

= Area of 2 triangles + area of 3 rectangles

= 2 × ½ × 3 × 4 + 4 × 8 + 5 × 8 + 8 × 3

= 12 + 32 + 40 + 24

= 108 cm²

Hence, 108 cm² cardboard will be needed to make this design.

Answer Below

Step-by-step explanation:

The diameter of a tire is 2.5 ft. a. Find the circumference of the tire. b. About how many times will the tire have to rotate to travel 1 mile?

a) The circumference of a circle is the perimeter of the circle. The circumference of the circle is the distance around a circle, that is the arc length of the circle. The circumference of a circle is given by:

Circumference = 2π × radius; but diameter = 2 × radius. Hence:

Circumference = π * diameter.

Given that diameter of the tire = 2.5 ft:

Circumference of the tire = π * diameter = 2.5 * π = 7.85 ft

b) since the circumference of the tire is 7.85 ft, it means that 1 revolution of the tire covers a distance of 7.85 ft.

1 mile = 5280 ft

The number of rotation required to cover 1 mile (5280 ft) is:

number of rotation = 5280 ft/7.85 ft per rotation = 672 rotations.

Answer:

1+5n+9y

Step-by-step explanation:

This is just combining like terms, so numbers with the same coefficient will be added together because this is combining like terms, and numbers w/ out a coefficient will be placed together because we are combining like terms

Step-by-step explanation:

2.) $230 x 28% = $64.40

$230 - $64.40 = $165.60 sales price

3.) $45,000 × 25% = $11,250

$45,000 - $11,250 = $33, 750 discount price

$45,000 + $11,250 = $56,250 mark up price

$56,250 - $33,750 = $22,500 answer

4.) $33,750 x 8.875% = $2995.31

$33,750 + $2995.31 = $36,745.31 with tax

5.) $56,250 x 8.875% = $4,992.19

$56,250 + $4,992.19 = $61,242.19 with tax

6.) $33,750 x 6% = $2,025.00 Tom's commision

Answer:

37.5 percent

Step-by-step explanation:

First, work out the difference (decrease) between the two numbers you are comparing(which is 15 in this case) . Next, divide the decrease by the original number and multiply the answer by 100.(15/40=0.375 times 100=37.5) If the answer is a negative number, this is a percentage increase

7x11 Is 77 and 89 - 77 equals 12 so 12 pairs of jeans would be left over.

Answer:

36 minutes

Step-by-step explanation:

If I read this correctly, Dracula jumps 1 time every 6 minutes. If he jumped 5 times in 30 minutes, then that means when he jumped a sixth time, it was 36 minutes that passed since:

30 / 5 = 6

So, if he were to jump a sixth time:

30 + 6 = 36

Therefore, Dracula jumps 1 time per 6 minutes.

Answer:

you have four walls. two of them 12*8 and the other two are 10*8 ( we used 8 in both because it's the height of the room). so it goes( 2*12*8)+(2*10*8) and it goes 352S

Step-by-step explanation:

let's say that walls A 12*8 and walls B 10*8. you have 4 walls ta wallpaper.

for walls A= 2*12*8=192

for walls B=2*10*12=160

in total, you need 160+192= 352 square feet of wallpaper
