Can Someone Please Tell Me The Formula You Would Use To Solve This And What The Area AND Perimeter Would

Answers

Answer 1

Answer:

Area: 1920 ft²

Perimeter: 176 ft

Step-by-step explanation:

Formula of Area of a Rectangle => A = width × length

Area = 40 × 48

= 1920 ft²

Formula of Perimeter of a Rectangle => P = 2 (width + length)

Perimeter = 2 ( 40 + 48)

= 2 (88)

= 176 ft

A right cubic prism has edges of 2 1/2 inches. How
many cubes with side lengths of inches would
be needed to fill the prism?
A. 125 cubes
B. 37.5 cubes
C. 18.75 cubes
D. 15.625 cubes

Answers

Answer:

Option D, the volume is 15.625 cubes

Step-by-step explanation:

For a cube of side length L, the volume is:

V = L^3

for the smaller cubes, we know that each one has a side length of 1 in, then the volume of each small cube is:

v = (1in)^3 = 1 in^3

Then:

1 in^3 is equivalent to one small cube

Here we know that the side length of our cube is (2 + 1/2) in

Then the volume of this cube will be:

V = [ (2 + 1/2) in]^3

To simplify the calculation, we can write:

2 + 1/2 = 4/2 + 1/2 = 5/2

Then:

V = ( 5/2 in)^3 = (5^3)/(2^3) in^3 = 125/8 in^3 = 15.626 in^3

This means that 15.625 small cubes will fill the prism.

So the correct option is D.  

Which of these figures is NOT a quadrilateral?

Answers

Answer:

the correct answer is A

step by step explanation

Figure A is NOT a quadrilateral. Then the correct option is A.

What is a quadrilateral?

The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees. In a quadrilateral, there are four vertices.

A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. In a rhombus, opposite sides are parallel and all sides are equal. In a parallelogram, opposite sides are parallel and equal.

Figure A is NOT a quadrilateral. Because two corners of the figure are rounded and in the quadrilateral, all the vertices are shaped.

Figure A is NOT a quadrilateral. Then the correct option is A.

A mailing supply company produces yellow mailing envelopes. The envelopes come in
a variety of sizes, but the length is always 4 centimeters more than double the width.
Write an equation to find the dimensions of an envelope that has a perimeter of 26
centimeters.

Answers

Answer:

Step-by-step explanation:

L=2W+4

P=2(L+W), using L from above makes this

P=2(2W+4+W)

P=2(3W+4)

P=6W+8

6W=P-8

W=(P-8)/6, since we are told P=26

W=(26-8)/6

W=18/6

W=3 cm, and since L=2W+4

L=2(3)+4

L=6+4

L=10 cm

So the dimensions of the envelope with a perimeter of 26cm is 3cm by 10cm

In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,

which law would you use? Laws of Sines or Laws of Cosines? and why?

Answers

Answer:

We would use the Law of Cosines to solve the question.

m∠ W = 121.8°

Step-by-step explanation:

In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,

which law would you use?

The Law we would use to find find m∠W is the Law of cosines, this is because in the question above we are given 3 known sides of a triangle and we are asked to find an unknown angle.

Law of cosines when we are to find an unknown angle =

m∠ W = arc cos [u² + v² - w²/ 2uv]

m∠ W = arccos [ 20² + 47² - 60²/ 2 × 20 × 47]

m∠ W = 121.81159°

Approximately = 121.8°

Answer:

Step-by-step explanation:

You have a 30-60-90 triangle. The sides of a 30-60-90 are in the ratio 1:√3:2.

The side opposite the 30° angle is 5, so the side opposite the 60° angle is 5√3, and the side opposite the 90° angle is 5×2 = 10.

x = 5√3

y = 10

Select the correct text in the passage.Which sentence best develops the author's thesis that Louise Nevelson was a celebrated artist who created completely new types of sculptures?Sculpting a MessagePeople who know artists say that artists look at the world differently. This saying was true for Louise Nevelson, one of the world's mostcelebrated sculptural artists. Until Louise Nevelson's time, sculptures were made primarily of carved stone or poured metal. Louise Nevelson,however, created completely different types of sculptures. Hers were assembled from ordinary objects.Artists of the first half of the twentieth century were inventive in their subject matter and technique. It was an exciting time in the art world.Even among innovators, Nevelson distinguished herself. Instead of cutting stone or pouring metal, she built her art. She deliberately soughtdiscarded items (she called them "found materials") such as pieces of wood, tin cans, and pieces of items out of trash cans. She grouped them invarying combinations inside boxes and then stacked the boxes on top of one another. Known as wall sculptures, these structures were usuallypainted a single color, most often blackSky Cathedral, one of Nevelson's most well-known sculptures, consists of 38 boxes of varying sizes. For the viewer, Nevelson's sculpturecreates a feeling very different from the origins of the materials. Viewers experience a sense of awe and mystery when they see her artwork.Writers have speculated about the meaning of her work, often seeing the boxes as filled with symbolism. For example, the disarray of objectsInside the boxes is said to represent her past, while the pieces of debris symbolize memories of unknown people or bits of life.ResetNext If co\/id wasn't a thing what would you be doing right now???
