Could somebody please answer these four questions with simple yet explanatory answers?

Answers

Answer 1

Answer: 1) Surface Area = 2(lw + lh + wh)
2(4*5+4*9+5*9) =202in^2
Surface Area=202in^2
Lateral Area= Perimeter of base * height
5+5=10 <--width+width
4+4=8 <---length + length
10+8=18 <--total perimeter
18 * 9=162in^2 <--multiplied the height +perimeter of base
Lateral Area=162in^2

2) Same concept as the previous one
Surface Area = 2(lw + lh + wh)
2(4*2+4*5+5*2) =76in^2
Surface Area= 76in^2

Lateral Area
Lateral Area= Perimeter of base * height
4+4=8
2+2=4
8+4=12
12 x 5=60
Lateral Area= 60in^2

Answer 2

Answer: Pooja answered #1 and #2 correct, so I shall make my life easier by answering #3 and #4 :P

#3 tests the concept of surface area. The gift wrap will be covering only the surface of each side. Surface area is all of the outside. Volume is all of the stuff inside.

So the surface area of rectangular prism can be found by the formula:
SA = 2(LW + LH + WH)
SA = 2(9*7 + 7*4 + 9*4)
SA = 2(63 + 28 + 36)
SA = 2(127)
SA = 254 in²

#4 also needs you to find the surface area.
So the surface area of a triangular prism can be found by this formula:
SA = bh + ( $\sf s_1 + s_2 + s_3$ )h
SA = (6.3*2) + (6.3 + 2.5 + 5.2)3
SA = 12.6 + (14*3)
SA = 12.6 + 42
SA = 54.6 cm²

Answers

remember
you can do ANYTHING to an equation as long as you do it to BOTH SIDES
also
a/a=1
ab/ab=1

so
we want to solve for h or 1h

T=pirh
divide both sides by pir (since pir/pir=1)
T/(pir)=1h
T/(pir)=h

C

T=πrh
πrh=T
(πr) * h=T
h=T/πr

Answer: C h=T/πr

How can you use the Pythagorean Theorem to solve real-world problems?You can use the Pythagorean Theorem to find missing ________ (angles or lengths) in objects that are_________. ( squares, right triangles, or equilateral Triangles)

Answers

You can use the Pythagorean Theorem to find missing lengths in objects that are right triangles.

What is Pythagorean Theorem?

The Pythagorean Theorem is a mathematical principle that relates to right triangles. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

You can use the Pythagorean Theorem to find missing lengths in objects that are right triangles.

The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

By rearranging the formula, you can solve for the missing length when given the lengths of the other two sides.

This can be applied to real-world problems involving measurements of objects or distances, such as determining the length of a ladder needed to reach a certain height on a wall or calculating the distance between two points on a map.

Find the percent of the number. 11.3% of 700

A.
7.91

B.
79.1

C.
791

D.
7910

Answers

First you need to convert 11.3% from percentage to number. To do this you just simply have to move the decimal place two places to the left, which gives us .113. To find out what 11.3% of 700 is you would just multiply .113 by 700.

.113 x 700 = 79.1

Answer is B.

700*0.113
=79.1 %

Answer is B.
