Angle A and Angle B are supplementary angles. If
m angle A = (2x + 26)° and m angle B = (x + 25)', then find the measure
of Angle B.

Answers

Answer 1

Answer:

12 Degrees

Step-by-step explanation:

angle A and angle B are supplementary angles.

angle A is 14 times as large as angle B.

Let angle A be x and let angle B be y.

then we have x+y=180

 

x=14y

14y+y=180

15y=180

y=12

x=168

Angle A is 168 degrees and angle B is 12 degrees.

The dimensions of a 7-cm by 2-cm rectangle are
multiplied by 3. How is the area affected?

Answers

Answer:

Step-by-step explanation:

9

Final answer:

Multiplying the dimensions of a rectangle by 3 increases its area by a factor of 9, which is the square of 3. The area of the rectangle goes from 14 cm^2 to 126 cm^2.

Explanation:

When the dimensions of a rectangle are multiplied by a certain factor, the area of the rectangle is affected by the square of that factor. Initially, the area of a 7-cm by 2-cm rectangle is 14 cm2. When the dimensions are each multiplied by 3, the new dimensions become 21 cm by 6 cm. Therefore, the new area is 21 cm  imes 6 cm = 126 cm2. The area scales in proportion to the square of the linear dimensions. If we compare the new area to the old area, we see that 126 cm2 / 14 cm2 equals 9, meaning the area has increased by a factor of 9, which is 32, since we multiplied the dimensions by 3. This principle applies generally: when a rectangle's dimensions are scaled by a factor, its area is scaled by the square of that factor.

The graph shows the solution for which inequalities

Answers

Answer:

Option 3

Step-by-step explanation:

y is less than the y values on the red line and greater than the y values on the blue line.

Equation of the red line:

y-intercept is clearly 3

using (0,3) & (-2,2)

Slope = (y2-y1)/(x2-x1)

= (3-2)/(0-(-2)) = 1/2

y = (1/2)x + 3

Equation of the blue line:

y-intercept is clearly -2

Using (0,-2) & (1,1)

Slope = (1-(-2))/(1-0) = 3/1 = 3

y = 3x - 2

y < (1/2)x + 3 & y > 3x - 2

The graph shows the solution for the following inequalities; C. y ≥ 3x - 2 and y ≤ -1/2(x) + 3.

How to determine an equation of this line?

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

[tex]y - y_1 = m(x - x_1)[/tex]

Where:

x and y represent the data points.m represent the slope.

First of all, we would determine the slope for the red line by using these points (2, 4) and (0, 3);

[tex]Slope(m)=\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope (m) = (3 - 4)/(0 - 2)

Slope (m) = 1/2

At point (0, 3) and a slope of 1/2, an inequality for this line can be calculated by using the point-slope form as follows:

y - 3= 1/2(x - 0)  

y = 1/2(x) + 3

y ≤ 1/2(x) + 3 (since the solid line is shaded below).

At point (0, -2) and a slope of 3, an inequality for this line can be calculated by using the point-slope form as follows:

y + 2= 1/2(x - 0)  

y = 3(x) - 2

y ≥ 3x - 2 (since the solid line is shaded below).

An architect uses a 3-D printer to create the scale model for a house that will be built. In the model the house is 53cm tall . The house will be 624 cm tall. The volume of the model is 0.8125 cubic meter. What is the volume of the house . (Note: 1 cubic meter = 1,000,000 cubic centimeters)

Answers

Answer:

The volume of the actual house is 1,324.94 cubic meters

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Height of the scale model = 53 cm

Height of the actual house = 624 cm

Scale of the model = 642/53 = 11.77

Volume of the scale model = 0.8125 cubic meters

2. What is the volume of the house?

For answering the question we have to find the width and the length of the model, then use the scale of the model for calculating the volume of the actual house, this way:

Volume of the scale model = 0.8125 cubic meters

Area of the scale model = Volume of the model/Height of the model

Area of the scale model = 0.8125/0.53

Area of the scale model = 1.533 square meters

Area of the scale model = Length * Width

Area of the scale model = 1.533 * 1

Now, we can calculate, the measurements of the house to calculate its volume:

Height of the actual house = 6.24 meters

Length of the actual house = 1.533 * 11.77 = 18.04 meters

Width of the actual house = 1 * 11.77 = 11.77 meters

Volume of the actual house = 6.24 * 18.04 * 11.77

Volume of the actual house = 1,324.94 cubic meters

Answer:

Part 1) [tex]\frac{5}{2}[/tex]  or  [tex]5:2[/tex]

Part 2) [tex]\frac{8}{1}[/tex]  or  [tex]8:1[/tex]

Step-by-step explanation:

Write the ratio as a fraction in simplest form

Part 1) 15 girls to 6 boys

we know that

To find out the ratio, divide the number of girls by the number of boys

so

[tex]\frac{15}{6}[/tex]

Simplify

Divide by 3 both numerator and denominator

[tex]\frac{5}{2}\ \frac{girls}{boys}[/tex]

Part 2) 24 plays for 3 teams

we know that

To find out the ratio, divide the number of plays by the number of teams

so

[tex]\frac{24}{3}[/tex]

Simplify

Divide by 3 both numerator and denominator

[tex]\frac{8}{1}\ \frac{plays}{team}[/tex]

Final answer:

To simplify the ratios 15 girls : 6 boys and 24 plays : 3 teams, find the greatest common factor and divide both parts of the ratio by it, resulting in the simplest forms  rac{5}{2} and 8, respectively.

Explanation:

To write the ratios as fractions in simplest form for the given scenarios:

For the ratio of 15 girls to 6 boys, the fraction would be  rac{15}{6}. To simplify, divide both the numerator and the denominator by their greatest common factor (GCF), which is 3. Thus, the simplest form is  rac{15 \/ 3}{6 \/ 3} =  rac{5}{2}.

For the ratio of 24 plays for 3 teams, the fraction is  rac{24}{3}. Again, to simplify, divide both the numerator and the denominator by the GCF, which is 3 in this case. The simplest form is  rac{24 \/ 3}{3 \/ 3} =  rac{8}{1}, which can also be written simply as 8 since a denominator of 1 implies the value is a whole number.

Determine whether the statement is true of false and support your reasoning: Mr. Flores has 100 pictures in a photo album. Of these pictures, 20 show his friends, 50 show his family, and 30 show his pet dachshund, Frou-Frou. Based on this information, the probability of Mr. Flores randomly selecting a picture of Frou-Frou is greater than the probability of randomly selecting a picture of his family

Answers

So, the given statement is false.

Step-by-step explanation:

Given , Mr. Flores has 100 pictures in a photo album. Of these picture , 20 show his friends , 50 show his family and 30 show his pet dachshund.

Probability formula:

[tex]P(A)=\frac{\textrm{Number of favorable outcomes to A}}{\textrm {Total number of out comes}}[/tex]

Total number of out come = 100

Number of photo of his family = 50

Therefore the probability of Mr. Flores selecting a picture of his family is

[tex]=\frac{50}{100}[/tex] [tex]=\frac{1}{2}[/tex] [tex]= \frac{5}{10}[/tex]

The probability of Mr. Flores selecting a picture of his friend is [tex]=\frac{20}{100}[/tex] [tex]=\frac{1}{5} = \frac{2}{10}[/tex]

The probability of Mr. Flores selecting a picture of his pet dachshund [tex]=\frac{30}{100}[/tex] [tex]=\frac{3}{10}[/tex]

Since [tex]\frac{5}{10}>\frac{3}{10}>\frac{2}{10}[/tex]

Therefore the probability of Mr. Flores randomly selecting a picture of his family is greater than the probability of randomly selecting a picture Frou -Frou.

So, the given statement is false.

A game designer must decide how to color four buildings that are in a row. Using only the colors yellow, green, red, and blue, each building must be painted with exactly one color. Any two neighboring buildings must be different colors, and the first and last buildings must be different colors. How many ways are there to paint the four buildings?

Answers

To determine how many ways to paint the buildings, we consider the choices for each building sequentially, considering the constraints. There are either 36 or 24 combinations, depending on the colors chosen for the first and last buildings. A step-by-step count confirms this range of possibilities.

A systematic approach gives us the general formula: 4 choices for the first building × 3 choices for the second building × 3 choices for the third building × (2 or 3) choices for the fourth building, depending on the first color chosen. This results in a total of 36 or 24 possible combinations, depending on the first and last color's relationship. A careful count avoiding the restrictions on the colors confirms this.

Question 2 How much does an individual notebook cost? Question 3 How much does a package of pencils cost? Question 4 How much does an individual marker cost?

Answers

Answer:

Notebook = $2.75

Pencil = $1.25

Markers = $ 0.50

Step-by-step explanation:

Stan:

n + 3p + 2m = 7.5

Jan:

2n  + 6p + 5m = 15.50

Fran:

n + 2p + 2m = 6.25

Stan - Fran:

p = 1.25

Lets replace p with 1.25

n + 3(1.25)  + 2m  = 7.5

2n + 6(1.25) + 5m = 15.50

n + 2(1.25) + 2m = 6.25

Simplify

n + 3.75 + 2m = 7.5

2n + 7.5  + 5m = 15.50

n + 2.50 + 2m = 6.25

n + 2m = 3.75     stan

2n + 5m = 8       jan

n + 2m = 3.75     fran

How do I use the cosine rule for these problems?

Answers

Answer:

see explanation

Step-by-step explanation:

Using the Cosine rule

a² = b² + c² - 2abcosA ← Rearranging for cosA gives

cosA = [tex]\frac{b^2+c^2-a^2}{2ab}[/tex]

(a)

let a = 10, b = 7, c = 8 and A = α, then

cosα = [tex]\frac{7^2+8^2-10^2}{2(7)(8)}[/tex] = [tex]\frac{49+64-100}{112}[/tex] = [tex]\frac{13}{112}[/tex], thus

α = [tex]cos^{-1}[/tex]( [tex]\frac{13}{112}[/tex] ) ≈ 83° ( to the nearest degree )

(b)

let the angle opposite side 7 be x

Using the Sine rule

[tex]\frac{10}{sin83}[/tex] = [tex]\frac{7}{sinx}[/tex] ( cross- multiply )

10sinx = 7sin83 ( divide both sides by 10 )

sinx = [tex]\frac{7sin83}{10}[/tex] , thus

x = [tex]sin^{-1}[/tex] ( [tex]\frac{7sin83}{10}[/tex] ) = 44°

The third angle can be found using the sum of angles in a triangle

third angle = 180° - (83 + 44)° = 180° - 127° = 53°

The 3 angles are 83°, 44°, 53°
