1. Using the figure below, what is the measure of angle ABE?

Answers

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°.

The ratio of the measurement of an angle to its supplement is 3:5. Find the measurement of the angle and its supplement.
-7th grade math

Answers

Answer:

The measurements of the two angles are 67.5° and 112.5°

Step-by-step explanation:

We can set up the equation just like a normal equation when you are finding x. Once we know what x is, then we can use that number and multiply it to 3 and 5 to find the measurements of the angles.

3x + 5x = 180

Combine like terms.

8x = 180

Divide 180 by 8.

x = 22.5

Now, we plug in x to 3 and 5.

3 * 22.5 = 67.5

5 * 22.5 = 112.5

Just to make sure our work is correct, let's add these numbers together.

67.5 + 112.5 = 180

The measurement of the angle is 67.5 degrees and the measurement of the supplement of the angle is 112.5 degrees.

What is supplementary angle?

When the sum of the two angle are equal to the 180 degrees, then these angles are called the supplementary angle of each other.

The ratio of the measurement of an angle to its supplement is 3:5. Let, the ratio,

[tex]\dfrac{3}{5}=x[/tex]

As, these angles are supplementary to each other. Thus,

[tex]3x+5x=180\\8x=180\\\x=\dfrac{180}{8}\\x=22.5[/tex]

Thus, the measurement of the angle is,

[tex]3x=3\times22.5\\3x=67.5[/tex]

The measurement of the supplement of the angle is,

[tex]5x=5\times22.5\\5x=112.5^o[/tex]

Hence, the measurement of the angle is 67.5 degrees and the measurement of the supplement of the angle is 112.5 degrees.

What is the diameter of earth? Round your answer to the nearest tenth. Use 3.14 for π.

Enter your answer in the box below.
____miles





Answers

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:

7930.3miles

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

A local car dealer has 150 cars on the lot. 30% of the cars are sedans. How many of the cars are NOT sedans?

Answers

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.

(HINT: You may factor or use the quadratic formula)

Answers

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

Does the point (4, 0) satisfy the equation y = –5x + 4?

Answers

Answer:

no

Step-by-step explanation:

y = –5x + 4

Substitute the point into the equation

0 = -5(4) +4

0 = -20+4

0 = -16

This is not true so it is not a solution to the equation

You just have to input the coordinate values into the equation
So...
0 = -5(4) + 4
0 = -20 + 4
0= - 16

So no this is wrong as they do not equal.

Hope this helps! :)

Everyone was already in class after the sound of the second bell. There was no sign of anyone. Gary smirked. He hadn't been caught skipping school in the past four months.
