Find out whether the angles are adjacent or vertical. Then find the value of x.

Answers

Answer 1

Answer:

x = 20

Step-by-step explanation:

angles are adjacent and add up to 180 degrees, so:

7x + x + 20 = 180

8x + 20 = 180

8x = 160

x = 20

Mrs. Thomas and Mrs. Maas were folding report cards to send home to parents. The ratio of the number of report cards Mrs. Thomas folded to the number of report cards Mrs. Maas folded is :. At the end of the day, Mrs. Maas folded a total of 273 report cards. How many did Mrs. Thomas fold?

Answers

Answer: 182 report cards

Step-by-step explanation:

The ratio of the number of report cards Mrs. Thomas folded to the number of report cards Mrs. Maas folded is 2:3.

Mrs. Maas folded 273 report cards so the number of report cards folded by Mrs. Johnson can be found using direct proportion. Assume Mrs. Johnson folded x report cards:

2 : 3

x : 273

Cross multiply to get:

3x = 546

x = 546 / 3

x = 182 report cards

Write the equation of the line that passes through (-4, 3) and is perpendicular to the line y = 7/5x-2/5

Answers

Answer:

y - 3 = (-5/7)(x + 4)

Step-by-step explanation:

The given line, y = 7/5x-2/5, has a slope of 7/5. Any line perpendicular to this one must have a slope tht is the negative reciprocal of 7/5, which is -5/7.

Use the point-slope formula to come up with an equation for this new line:

Hailey is going to paint a wall in her bedroom. The bottom part of the wall is a rectangle (16ft. x 18ft.), and the top part is a triangle (8 ft. high x 18ft. long). What is the total area of the wall?

Answers

Answer:

Area of wall = 360 ft²

Step-by-step explanation:

Given:

One part of wall (Rectangle) = 16ft x 18ft

Another part of wall (Triangle) = 8ft x 18ft

Find:

Area of wall

Computation:

Area of wall = Area of rectangle + Area of triangle

Area of wall = (l x b) + (1/2)(b)(h)

Area of wall = (16 x 18) + (1/2)(8)(18)

Area of wall = 288 ft² + 72 ft²

Area of wall = 360 ft²

Mrs. Patterson but a set of building blocks for her son each cube shaped block measured 4 cm on one side what is the volume of six building blocks

Answers

Given:

The shape of all building blocks is a cube of side 4 cm.

To find:

The volume of six building blocks.

Solution:

Volume of a cube is:

[tex]V=a^3[/tex]

Where, a is the side length of the cube.

Putting [tex]a=4[/tex], we get

[tex]V=(4)^3[/tex]

[tex]V=64[/tex]

It means the volume of each building block is 64 cubic cm.

Now, the volume of six building blocks is

[tex]Volume=6\times V[/tex]

[tex]Volume=6\times 64[/tex]

[tex]Volume=384[/tex]

Therefore, the volume of six building blocks is 384 cubic cm.

Maggie is rock climbing. After reaching the summit, she descends 14 feet in 213 1 3 minutes. If she continues at this rate, where will Maggie be in relation to the summit after 8 minutes?

Answers

Answer:

48 feets

Step-by-step explanation:

Given that:

Maggie descends 14 feets in 2 1/3 minutes

14 feets takes 7/3 minutes

The amount of feets she descends after 8 minutes will be x ;

14 = 7/3

x = 8

Cross multiply

7/3 * x = 14 * 8

7x /3 = 112

7x = 112 * 3

7x = 336

x = 336 / 7

x = 48 feets

Solve the following quadratic equation for all values of xx in simplest form.(Solving Quadratics with Square Roots (Level 1)
(x+10)^2-8=8

Answers

I think first you have to expand the bracket in order to get x^2+100
Then u have x^2+100-8=8
Then u have to bring 8 over the equality sign and minus it with the other -8 to get -16
It becomes x^2+100-16
Then u find the factors of 16 which add up to 100 but since that’s not possible with the formula I normally use u have to do

A rope 13 meters long will just reach from the top of a flagpole to a point on the ground 12 meters from teh base of the flagpole. Find the height of the flagpole

Answers

Answer:

the height of the flagpole is 5 meters

Step-by-step explanation:

The computation of the height of the flagpole is given below

Given that

the length of the rope is 13 meters

And, the ground would be 12 meters

Based on the above information, the height of the flagpole is

= √13^2 - √12^2

= √169 - √144

= √25

= 5 meters

hence the height of the flagpole is 5 meters

A cereal box is 8 1/2
inches long, 2 1/2
inches wide, and 12 inches high. What is the volume of the box?

The volume of the cereal box is blank cubic inches.

Answers

Answer:

V = 255

Step-by-step explanation:

Cereal box is a rectangular prism.

Rectangular Prism formula:

V = whl

Given:

w = 2.5

h = 12

l = 8.5

Work:

V = whl

V = (2.5)(12)(8.5)

V = 255

Answer: 1428

Step-by-step explanation: Length of the cereal box = 8 1/2 inches

= 17/2 inches

Width of the cereal box = 3 1/2 inches

= 7/2 inches

Height of the cereal box = 12 inches

Then

Volume of the cereal box = Length * Width * Height

= (17/2) * (7/2) * 12 cubic inches

= 17 * 7 * 12 cubic inches

= 1428 cubic inches
