The length of Chen’s office is 15.5 feet and the width is 7.8 feet. Use the formula P = 2ℓ + 2w to find the perimeter of the office.

Answers

46.6 feet

Step-by-step explanation:

P = 2ℓ + 2w

P = 2(ℓ + w)

P = 2(15.5 + 7.8)

P = 2(23.3)

What is the value of W in a exterior angle theorem

Answers

Answer:

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle.

so:

30 + 2w - 8 = w + 48

22 + 2w = w + 48 export like terms to the same side of the equation

2w - w = 48 - 22 subtract

w = 26

Answers

Answer:

See below.

Step-by-step explanation:

First question:

Think of the x-axis as a mirror. Quadrilateral is above the x-axis. Quadrilateral is below the x-axis. Quadrilateral ABCD was reflected across the x-axis. Quadrilateral A'B'C'D' is a mirror image of quadrilateral ABCD.

Quadrilateral ABCD undergoes a reflection across the x-axis to form quadrilateral A'B'C'D'.

Second question:

Quadrilaterals ABCD and A"B"C"D" are both turned the same way. Quadrilateral A"B"C"D" is just moved left and down from quadrilateral ABCD. That transformation is called a translation.

Quadrilateral ABCD undergoes a translation 7 units left and 1 unit down to form quadrilateral A"B"C"D".

Find the area of the following kite:

Answers

Answer:

[tex]48 cm^2[/tex]

Step-by-step explanation:

Each of the small triangles are right, so we can add up all the small triangle's areas to find the total area.

The 4-by-10 triangle: The area is [tex]4*10/2=40/2=20[/tex].

The other 4-by-10 triangle has the same side lengths and hence the same area, so the area is [tex]20[/tex].

The 4-by-4 triangle: The area is [tex]4*4/2=8/2=4[/tex].

The other 4-by-4 triangle has the same area, [tex]4[/tex].

The total area is [tex]20+20+4+4=\boxed{48} cm^2[/tex].

Bus X travels 40 miles per hour for 2 hours; Bus Y travels 60 miles per hour for 1 1/2 hours. What is the difference, in miles, between the number of miles traveled by Bus X and the number of miles traveled by Bus Y?

Answers

Answer:

it should be 250m

Step-by-step explanation:

Bus X travels 40m for 2h which gives you 80m and Bus Y travels 60m for 11/2h which gives you 330m so the difference in miles is 250m

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2 h, and Car B traveled the distance in 1.5 h. Car B traveled 15 mph faster than Car A.

How fast did Car B travel?

(The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.)

Answers

Answer:

60mph

Step-by-step explanation:

2s - 30 = 1.5s

2s - 1.5s = 30

.5s = 30

s = 60 mph is car B's speed

ANALYZE The surface area of a three-dimensional object is the sum of the area of the faces. If represents the length of the side of a cube, write a formula for the surface area S of the cube.

Answers

Step-by-step explanation:

If X represents the length of the side of a cube, the formula for the surface area of the cube, S =?

solution :

the area of each face of the cube = side × side

= X × X = X²

the cube has 6 similar faces, so the surface area of the cube could be:

S = 6 × X² = 6X²

Answer:

Surface Area = 6 × S²

Step-by-step explanation:

the surface area fo the cube :

SA = 6 × lenght × lenght

if lenght = S, the surface area fo the cube :

SA = 6 × lenght × lenght

SA = 6 × S × S

SA = 6 × S²

To isolate the variable in 1/4x multiply by _ or divide by _

Answers

Answer: To isolate the variable in ¹/₄ x multiply by 4 or divide by 1

Step-by-step explanation:

Let ¹/₄ x = a

multiply by 4: 4 (¹/₄) x = 4 a

1 x = 4 a

divide by 1: ¹/₁ x = ⁴/₁ a

x = 4a [x is now isolated]

To isolate the variable in 1/4x multiply by 4 or divide by 1/4

How to isolate the variable in 1/4x

From the question, we have the following parameters that can be used in our computation:

Expression = 1/4x

To isolate the variable in 1/4x, we multiply by 4

So, we have

Expression = 1/4x * 4

Expression = x

To isolate the variable in 1/4x, we divide by 1/4

Expression = 1/4x / 1/4

Expression = x
