HELP PLZZ I FORGOT HOW TO DO THIS!!!! What is the surface area of the square pyramid represented by the net?
Enter your answer in the box.
Answers
Answer:
39[tex]ft^{2}[/tex]
Step-by-step explanation:
Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height
All four triangles are similar. So finding the area of one triangle, will be the area of the other triangles.
[tex]\frac{1}{2}[/tex] × 3 × 5 = 7.5[tex]ft^{2}[/tex]
∴ The area of 4 triangles are 7.5 × 4 = 30[tex]ft^{2}[/tex]
Then the only shape remaining is the square.
Area of the square = [tex]length^{2}[/tex] (all the sides of a square are equal)
= [tex]3^{2}[/tex] = 9[tex]ft^{2}[/tex]
Total surface area = 30 + 9 = 39[tex]ft^{2}[/tex]

Dracula jumped 5 times every 30 minutes at that rate, how long,in minutes will it take to jump 6 times?
Answers
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.

A business named Beyond Boxes is considering adding a box in the shape of a triangular prism as shown. How much cardboard will be needed to make this design?
A.96 cm2
B.102 cm2
C.108 cm2
D.76 cm2
Answers
Answer:
120
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.

Drew wants to wallpaper his bedroom. The room is 10 ft long, 12 ft wide, and 8 ft tall. How many square feet of wallpaper does he need? So I got this question wrong and is wondering how I can get 352 square feet as my answer since that is what my teacher got and I don't know she got that so can someone plz help explain.
Answers
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

The diameter of a tire is 2.5 ft. Use this measurement to answer parts a and b. Show all work to receive full credit.
A. Find the circumference of the tire.
B. About how many times will the tire have to rotate to travel 1 mile? (1 mile = 5,280 ft)
Answers
Answer:
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.
