Answer: I would say the angle would have to be around 85* because with 53 being on the bottom left corner and the 20* at the top and 85 at the left it would be close when you connect them

Step-by-step explanation:

Answer:(2x+1)x=45

x=4.5

4.5*2+1=10

Step-by-step explanation:

Answer:

−x^2 − 8x

Step-by-step explanation:

Lets say y is the missing value

Add -x^2 to both sides.

x^2+8x+y+−x^2=0+−x^2

8x+y=−x^2

Add -8x to both sides.

8x + y + −8x = −x^2 + −8x

y = −x^2 − 8x

So the whole equation would be

x^2 + 8x + −x^2 − 8x = 0

Answer:

4x10=40-2=38

38% = 0.38 in decimal form. Percent means 'per 100'. So, 38% means 38 per 100 or simply 38/100. If you divide 38 by 100, you'll get 0.38 (a decimal number).

Step-by-step explanation:

If the ratio of the two sides of the triangles are the same then the third sides of the triangle will be parallel. Then the correct figure is D.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

If the ratio of the two sides of the triangles are the same then the third sides of the triangle will be parallel.

⇒ 5.5/15 = 6.6/18

⇒ 0.366 = 0.366

Then the correct figure is D.

Answer: Bertha nació el 18 de septiembre de 1990.

Step-by-step explanation:

Gonzalo nació el 18 de septiembre de 1945.

Bertha nació cuatro décadas y un lustro después.

Una década son 10 años

Un lustro son 5 años

Entonces 4 décadas y un lustro son:

4*10 años + 5 años = 45 años

Esto significa que Bertha nació 45 años después que Gonzalo.

Entonces si Gonzalo nació en 1945, Bertha nació en el año:

1945 + 45 = 1990

Bertha nació el 18 de septiembre de 1990.

La fecha de nacimiento de Bertha es el 18 de septiembre de 1990.

A decade is composed of 10 years. So, if there are 'x' decades, then that means there are going to be [tex]10 \times x[/tex] years in it.

For this case, we are given that:
Date of birth of Gonzelo is 18th of Sept. 1945

Bertha born after 4 decades and 5 years of Gonzelo's birth.

4 decades = 4 times 10 = 40 years

Thus, 4 decades + 5 years = 40 + 5 = 45 years.

45 years after 1945 uis 1945 + 45 = 1990

Thus, date of birth of Bertha is 18th Sept. 1990

Answer:

Step-by-step explanation:

1. the company C used 10 drivers

2.      6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The Mean = 10  

(6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)

4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4  = 16/10 = 1 6/10

3. The groups that had the most deliveries where group A and B

4. So if there are 6 deliveries of group A and 14 deliveries from group B i think the MAD would be 4

By reading the dot plot,

Number of drivers used by company C in its sample = 10

Mean absolute deviation for company C's data = 2

Company B has the greatest mean number of deliveries.

The mean deliveries of company B is 4 times MAD of company A.

Dot plot is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis.

Number of units used in the sample of a dot plot can be calculated by simple counting.

The mean absolute deviation (MAD) is the mean distance between each data value and the mean of the data set.

We are given the sum of each point from the mean. It is 20. Mean absolute deviation can be calculated by dividing this sum by number of observations.

Mean absolute deviation of company C  = 20/10 = 2.

Mean A = 6

Mean B = 14

Mean B - Mean A = 8 = 4 * 2 = 4 times MAD (since MAD =2 for both companies).

Answer:

153.9

Step-by-step explanation:

the circumference is equal to the radius times 2 times pi or 3.14

the radius is equal to half the diameter.

39/2=24.5

24.5x2x3.14=153.86 but it tells us to round to the nearest tenth and when rounded it equals 153.9

Answer:

A.) 555 in.^2

Step-by-step explanation:

When solving these types of things, I usually like to cut it up into smaller, easier to manage shapes.

                                                      44 - 30 = 14

                                                      14/2 = 7

Now that we filled in the information not listed, we can finally solve:

 The base of one triangle is 7 inches, and the height is 15 inches.

Now, we just multiple and divide it by 2 for one triangle (it would be 52.5 inches).

But, we don't need to divide it by two because both triangles are the same size, so we can just get the sum of the area of both triangles combined by skipping that step (because triangles are half a square and two of those triangles make a full square).

7 x 15 = 105

The area of both triangles combined: 105 in.^2

 Next, we need to solve the area of the rectangle. This is easy considering all you have to do is multiply 15 by 30 (length times width).

15 x 30 = 450

The area of the rectangle: 450 in.^2

 Now, the final step. Addition. All you need to do is add up all the sums, and you're done.

450 + 105 = 555

The area of entire figure: 555 in.^2

NOTE: the symbol '^' represents exponents, so when you see 555 in.^2, it means inches squared (or to the power of 2)

I think it is 20 square units if I am not correct sorry please let me know if it is correct

The expression 6e² represents the surface area of a cube where e represents the length of each edge. What is the surface area, in square centimeters, of a 5-centimeter cube?

The surface area of a cube is expressed as: 6e²

Where e = Length of each edge

The surface area, in square centimeters, of a 5-centimeter cube

e = 5cm

Therefore, the surface area of the cube = 6 × 5²

= 6 × 25

x = 2

Step-by-step explanation:

You can make a ratio out of this!

2 / x = (x+1) / 3

1. Cross multiply^

2. 2 * 3 = x (x+1)

3. 6 = x^2 + x

3. x^2 + x - 6

4. Factor^

5. (x-2)(x+3)

6. x - 2 = 0 turns into x = 2

7. x + 3 = 0 turns into x = -3

8. There's not way to measure -3 yet, so you are left with x = 2
