how do you solve the following problem with a rectangular fraction model ​

Answer:

Missing angle = 135°

Step-by-step explanation:

Given:

Pentagon shape

Number of right angle = 3

Remain two angles are equal

Computation:

Sum of Pentagon angles = 540°

So,

90 + 90 + 90 + a +a = 540

270 + 2a = 540

a = 135°

Missing angle = 135°

Answer:

[tex]\frac{31}{12}[/tex] more nuts would be used by Miguel then raisins

Step-by-step explanation:

The computation is shown below:

Nuts used [tex]= 5 \frac{1}{3} = \frac{16}{3}[/tex]

Raisins used [tex]= 2 \frac{3}{4} = \frac{11}{4}[/tex]

Now the difference between them is

[tex]= \frac{16}{3} - \frac{11}{4}\\\\= \frac{64 - 33}{12} \\\\= \frac{31}{12}[/tex]

Hence, [tex]\frac{31}{12}[/tex] more nuts would be used by Miguel then raisins

Answer:

528

Step-by-step explanation:

Surface area of bottom block + Surface area of top block - 2(Shared surface area)

Bottom block: 2(10*12) + 2(5*12) + 2(5*10) = 240 + 120 + 100 = 460 square inches

Top block: 2(2*2) + 4(2*8) = 8 + 64 = 72 square inches

Shared surface area = 2*2 = 4 square inches

Plugging into our formula:

460 + 72 - 4 = 528 square inches

The length of the base of the following pyramid when the height, angle of elevation is given so it is 158 meters.

Since

The height of the pyramid is 71 meters and the angle of elevation of the base of the pyramid is 42°.

So,

[tex]tan (42) = height \div base\\\\base = height \div tan (42)\\\\base = 71\div tan\ (42)\\\\[/tex]

base = 78.85 m

Now

length of the base pyramid = 2× length of the base of the right triangle

= 2 ×78.85

= 157.7

≈ 158 m

Hence, The length of the base of the following pyramid when the height, angle of elevation is given so it is 158 meters.

Answer: 27°

Step-by-step explanation: Here, we're asked to find the missing angle measure in the triangle shown which is represented by the variable x.

To find the value of x, remember that the sum of the

measures of the angles in a triangle is 180°

So we can setup the equation 63 + 90 + x = 180.

Remember that a box indicates a 90° angle.

Now to solve for x, let's first simplify on the left side of the equation.

63 + 90 is 153 so we have 153 + x = 180.

Now to get x by itself, we subtract 153 from both sides of the equation.

On the left side of the equation, 153 - 153 cancels out and we have x

and on the right side of the equation, 180 - 153 is 27.

This means that the missing angle in the triangle is 27°.

Answer:

x = 34.85

Step-by-step explanation:

Apply trigonometric ratio formula to find x

Reference angle = x

Side opposite to x = 4

Hypotenuse = 7

Therefore,

Sin x = opp/hyp = 4/7

x = sin-¹(4/7)

x = 34.85° (nearest hundredth)

Answer:

800 Kwh

Step-by-step explanation:

To solve this problem, we need to find the difference in energy saved and then multiply by the cost of 1kWh of electricity

Let's first of all calculate the the difference in energy saved

Data;

[tex]1200 - 400 = 800kWh[/tex]

Maggie would've saved 800kWh in one year.

But since we were not given a standard cost of electricity, we would assume that 1kWh will cost $1.

So, to determine how much she must've saved, we simply multiply $1 by 800kWh

[tex]1 * 800 = $800[/tex]

Using our assumptions, she would've saved $800 in one year.

Answer:

C) Angle X Y W is 76 degrees. The length of X Y is 5, the length of W Y is 10, and the length of W X is y.

Step-by-step explanation:

On which triangle can the law of cosines be applied once to find an unknown angle measure?

The Law of cosines is given as:

a² = b² + c² - 2bccos(A)

From the options given above, the correct option is Option C

C) Angle X Y W is 76 degrees. The length of X Y is 5, the length of W Y is 10, and the length of W X is y.

This is because:

Law of Cosines helps us to find an unknown side of a triangle when we are given 2 known sides and 1 angle.

In the above question, we are given angle 76 degree, and the length of two sides: The length of X Y is 5, the length of W Y is 10

The unknown side is the length of W X which is represented as y.

Hence, Option C is the correct option.

Given:

Total number of people survey = 1,400

Number of people satisfied with the​ car = 980

Find:

Percent of people satisfied with the​ car

Computation:

Percent of people satisfied with the​ car  = [Number of people satisfied with the​ car / Total number of people survey]100

Percent of people satisfied with the​ car  = [980 / 1400]100

THANK YOU.

Answer:

1. x=2

2. x= 0.33

Step-by-step explanation:

1.So to start off you have a coefficient for 2 so you have to find what 2 to the power of 2 is =4 so then you have your new problem 4x+5=13 next you need to get 4x by itself so

-5 -5

then you have 4x=8. you divide by 4 on both sides

4. 4

so then you get x=2

2.So same here find what 3 to the power of 2 is =9

New equation 4x-1=9x+4x-4. Then combine like terms on the right you cant do it on the left because that is a separate part and those dont merge like terms so

9x+4x = 13x

new equation. 4x-1=13x-4

next subtract 4x on both sides

13x-4x=9x

new equation. -1=9x-4

next add 4 to both sides

-1+4= 3

new equation. 3=9x

so then divide 9 on both sides

3÷9= 0.33

x= 0.33

Hope this made sense and helps

Step-by-step explanation:

Answer:B

Step-by-step explanation

The slope of the linear relation is -0.0018 and the y-intercept will be 212. The correct option is B.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data in the table is,

Altitude(x)       Boiling point (y)

0                      212.0

500                 211.1

The slope will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( 211.1 - 212  ) / (500 - 0 )

Slope = -0.0018

The y-intercept will be calculated as,

y = mx + c

212 = 0 + c

c = 212

Therefore, the slope of the linear relation is -0.0018 and the y-intercept will be 212. The correct option is B.
