Answer:

The angle of ∠ABE is 40°.

Step-by-step explanation:

Given that ∠ABE and ∠CBD are opposite vertical angles so they have the same measure of angles.

Because ∠ABE and ∠CBD are vertical angles, ∠ABE = ∠CBD = 40°.

Answer:

105 cars

Step-by-step explanation:

150cars=100%

and if 30% of the cars are sedans then the cars which are not sedans is

100%-30% =70%

if 150 cars=100%

? cars=70%

if less more devides

70%/100%×150cars

all zeros cancel which would be left with

7× 15

105 cars.

Answer:

The answer is 105

So that 30% of those cars are 45 Sedans of the 150 cars.

Now we need to find out how many cars are in that remaining 70%

In order to do this we need to subtract 45 from 150

So 150 minus 45 is 105

Finally, we know that that remaining 70% is 105 cars that aren't Sedans.

So 105 cars are not Sedans.

Answer:

The answer is "Option D".

Step-by-step explanation:

A line is a horizontal 1D-dimensional representation without any thickness and extends in every way. It sometimes is also known as the straight line. The line, which connects two planes lies simultaneously on both planes, that's why in this question only "option D" is correct.

Answer:

D>

Step-by-step explanation:

Answer: D. Square

The cross section is shown as the shaded region. There are four sides to the shaded figure, so the cross section is a quadrilateral. This rules out choice C. We can also cross choice B off the list because cross sections of 3D figures are 2 dimensional.

Choice A is ruled out as well because we have both pairs of opposite sides that are parallel. The only thing left is choice D. This is true assuming we have a square prism. Any cube is a square prism that has its height equal to the width and length.

Answer:

w = - 5, w = - 3

Step-by-step explanation:

Given

w² + 8w + 15 = 0

Consider the factors of the constant term (+ 15) which sum to give the coefficient of the w- term (+ 8)

The factors are + 5 and + 3 , since

5 × 3 = 15 and 5 + 3 = 8 , thus

(w + 5)(w + 3) = 0 ← in factored form

Equate each factor to zero and solve for w

w + 5 = 0 ⇒ w = - 5

w + 3 = 0 ⇒ w = - 3

Question:

The Whispering Lakes  Neighborhood Association is  having a hamburger cookout.  Each family can choose whether  to order the hamburgers or  bring their own. Use the  information in the table to solve  the number stories. Use  drawings, tables, or equations  to show what you did.

Mrs. Ward found 80-ounce packages of hamburger on sale. If she needs to make  2 of each size hamburger, how many packages of meat will she need to buy?

Answer:

The number of meat packages is

100/80 = 1.25 = 5/4

Assuming that the number of packages cannot be in fraction, then she would need at least 2 packages of meat.

Number of meat packages = 2

Step-by-step explanation:

Please refer to the attached table where we are given size of hamburgers and the weight of corresponding hamburger patty in pounds.

small = 1/8 lb

medium = 1/4 lb

large = 1/2 lb

jumbo = 3/4 lb

king of burgers = 1 1/2 lb = 3/2 lb

To make 1 of each hamburger we need

Total weight of patty = 1/8 + 1/4 + 1/2 + 3/4 + 3/2

Total weight of patty = 25/8 = 3.125 lb

But she needs to make  2 of each size hamburger so,

Total weight of patty = (25/8)×2 = 25/4 = 6.25 lb

Mrs. Ward found 80-ounce packages of hamburger on sale

first we have to convert pounds into ounces

We know that 1 pound has 16 ounces

6.25×16 = 100 ounces

So the number of meat packages required is

100/80 = 1.25 = 5/4

Assuming that the number of packages cannot be in fraction, then she would need at least 2 packages of meat.

Number of meat packages = 2

Answer:

x = 6

Step-by-step explanation:

4x-1=2x+11

Subtract 2x from each side

4x-2x-1=2x-2x+11

2x-1 =11

Add 1 to each side

2x-1+1 = 11+1

2x = 12

Divide by 2

2x/2 = 12/2

x = 6

1)

Lines X and W intersect 2 planes, while line Y intersects 3 and linen Z and V intersect one plane,

So, answer is lines X and W (don't know about Y, since it intersects more than two planes)

2) Lines Z and V intersect only one of the planes (the other lines intersect more than one, so don't know about them)

3) Line Y has points in all three planes (the rest have in either 2 or one planes)

The line which is the intersection of wo of the planes shown is.

1) Lines X and W intersect 2 planes, while line Y intersects 3, and lines Z and V intersect one plane,

So, the answer is lines X and W (don't know about Y, since it intersects more than two planes)

The line which intersects one of the planets Tatou is.

2) Lines Z and V intersect only one of the planes (the other lines intersect more than once, so don't know about them)

The line which has points on three of the planes shown is.

3) Line Y has points in all three planes (the rest have in either 2 or one plane)

Basic geometric concepts are based on three basic concepts. They are a point, a line, and a plane. We cannot specify the terms. However, it does refer to a position mark and has a precise location.

Answer:

x = 6

Step-by-step explanation:

The scale factor is

28/8 = 7/2

We take the ratio of the larger side over the smaller side

Using ratios we can find the sides

28         21

----- = ---------

8           x

Using cross products

28x = 21*8

28x =168

Divide each side by 28

28x/28 = 168/28

Answer:

756.5 =x

Step-by-step explanation:

To find the perimeter of a rectangle

P = 2 (l+w)

4533 = 2 ( x+3  + 2x-6)

Combine like terms

4533 = 2 ( 3x -3)

Distribute

4533 = 6x -6

Add 6 to each side

4533+6 = 6x

4539 = 6x

Divide by 6

4539/6 =x

Answer:

Diameter of the earth is 7930.25 miles

Step-by-step explanation:

To find the diameter of the earth, we will follow the steps below:

first write the formula of the circumference

c = 2πr ---------------------------------------------------------------------------------------------(1)

where r is the radius  and c is the circumference

from the diagram below, circumference is given to be 24901 miles

π = 3.14

substitute the value of c and π  into equation (1) and solve for r

c = 2πr

24901 = 2 × 3.14× r

24901 = 6.28 r

Divide both-side pf the equation by 6.28

24901/6.28 = 6.28 r/6.28

3965.1274≈ r to the nearest tenth

r≈ 3965.1274 miles

But diameter = 2r

diameter = 2 × 3965.1274

diameter ≈ 7930.25  to the nearest tenth

Diameter of the earth is 7930.25 miles

Answer:

Step-by-step explanation:

The earth is spherical in shape. The formula for calculating the circumference of a sphere is πd where d is thee diameter of the earth.

C = πd

Given C = 24, 901miles and π = 3.14, on substituting,

24, 901 = 3.14d

d = 24,901/3.14

d = 7930.255

d ≈ 7930.3miles to the nearest tenth

Answer:

a) 10.73%

b) 45.60%

c) 0.0094%

d) 54.4%

Step-by-step explanation:

The probability of one transistor being defective is equal the number of defective transistors over the total number of transistors

a)

The probability of the first one being defective is 4/24, and then the probability of the second one being defective is 3/23, because we have one less defective transistor. The probability of the third one being not defective is 20/22, and the fourth one not being defective is 19/21. We also multiply the final probability by a combination of 4 choose 2, because the defective transistors can be any 2 of the group of 4:

C(4,2) = 4! / (2! * 2!) = 6

P = 6 * (4/24) * (3/23) * (20/22) * (19/21) = 0.1073 = 10.73%

b)

Similar to the letter a), we have:

First one not defective: P = 20/24

Second one not defective: P = 19/23

Third one not defective: P = 18/22

Fourth one not defective: P = 17/21

P = (20/24) * (19/23) * (18/22) * (17/21) = 0.4560 = 45.60%

c)

First one defective: P = 4/24

Second one defective: P = 3/23

Third one defective: P = 2/22

Fourth one defective: P = 1/21

P = (4/24) * (3/23) * (2/22) * (1/21) = 0.000094 = 0.0094%

d)

If we want at least 1 defective, we just need to subtract 100% from the case where all 4 are not defective:

P = 1 - 0.4560 = 0.5440 = 54.4%

In this exercise we have to use the knowledge of probability to calculate each of the requested probabilities, so we can say that:

a) [tex]10.73\%[/tex]

b) [tex]45.60\%[/tex]

c) [tex]0.0094\%[/tex]

d) [tex]54.4\%[/tex]

a)The probability of the first one being defective is 4/24, and then the probability of the second one being defective is 3/23, because we have one less defective transistor. So the combination will be:

[tex]C(4,2) = 4! / (2! * 2!) = 6\\P = 6 * (4/24) * (3/23) * (20/22) * (19/21) = 0.1073 = 10.73%[/tex]

b)So find the not defective, we have:

[tex]P = (20/24) * (19/23) * (18/22) * (17/21) = 0.4560 = 45.60%[/tex]

c)So find the defective, we have:

[tex]P = (4/24) * (3/23) * (2/22) * (1/21) = 0.000094 = 0.0094%[/tex]

d)We just need to subtract 100% from the case where all 4 are not defective:

[tex]P = 1 - 0.4560 = 0.5440 = 54.4%[/tex]
