Answer:

x = 98 degrees

Step-by-step explanation:

A heptagon has a total of 900 degrees for the interior angles. Add up all the angles and then subtract from 900 to find x.

146+122+142+140+110+142 = 802.

900-802 = 98

Answer:

x = 98

Step-by-step explanation:

This shape has 7 sides. Using the formula n - 2 we can get the number of triangles. n represents the number of sides.

n - 2 = 5

All triangles have 180 degrees, so multiply 180 by the number of triangles (5).

180 × 5 = 900

The total number of degrees in this shape is 900. Adding the other angle measures and then subtracting them from 900 gives us x.

146 + 122 + 142 + 140 + 110 + 142 = 802

900 - 802 = 98.

x = 98

Answer:

9.50 + x = 35

Step-by-step explanation:

Assuming you spent $9.50 on popcorn and spent $35 in total, what would you think x repreaents? The tickets dont have an amount, so x is tickets.

Answer:

126.5

Step-by-step explanation:

Divide the shape into two, so you have a triangle and a rectangle.

Area of Rectangle:

A = bh

  = (11)(8)

  = 88

Area of Triangle:

A = 1/2bh

   = 1/2(11)(7)

   = 38.5

Add the two areas and the answer is 126.5

Answer:

5 miles/hour

Step-by-step explanation:

the distance is the length of the track which is given as 1/4 of a mile. she completes each lap in 1/20 of an hour so divide the distance by the time taken to go around the distance

Answer:

Elena's speed is 5 miles/hour

Step-by-step explanation:

The speed is defined as the covered distance per unit time. The distance covered is the length of the circular track which is given as  of a mile. We also know that she completes each lap in of an hour. To get her speed, we have divide the distance covered by the time taken to cover this distance and you come out with 5. She can run 5 miles each hour. Or in other words you take 20 divided by 4 you get 5

Answer:

[tex]Weight = 6.3 kg[/tex]

Step-by-step explanation:

Given

[tex]Total = 8.4kg[/tex]

[tex]Pears = \frac{1}{4}[/tex]

Required

Determine the weight of apples

First, we calculate the fraction of apple.

[tex]Apple = 1 - Pears[/tex]

[tex]Apple = 1 - \frac{1}{4}[/tex]

Take LCM

[tex]Apple = \frac{4-1}{4}[/tex]

[tex]Apple = \frac{3}{4}[/tex]

The weight is then calculated as:

[tex]Weight = \frac{3}{4} * Total[/tex]

[tex]Weight = \frac{3}{4} * 8.4kg[/tex]

[tex]Weight = \frac{3* 8.4kg}{4}[/tex]

[tex]Weight = \frac{25.2kg}{4}[/tex]

[tex]Weight = 6.3 kg[/tex]

Hence, the apples weigh 6.4kg

Answer:

A shape has reflection symmetry if there exists a line of reflection that carries the shape onto itself. This line of reflection is called a line of symmetry. In other words, if you can reflect a shape across a line and the shape looks like it never moved, it has reflection symmetry.

Answer:

y=5/4x

Step-by-step explanation:

The equation for the line passing through points (0, 0),(4, 5), and (8, 10) is; y = (5/4)x

From the coordinate, (0, 0), we can conclude that the y-intercept of the line is 0.

In essence, to determine the equation of the line, we must evaluate the slope by consider two points on the line namely;

Slope, m = (y2 -y1)/(x2 - x1).

Slope, m =( 10 - 5)/(8-4)

Therefore, the equation of the line is;

Answer:

I think the answer is c because the arrow has to pointing positive.

Answer:

1/6x

Step-by-step explanation:

the slope intercept form is: y = mx + b

m = slope

b = y-intercept.

When you already have in the form the slope is where m is, so the number that's is with x. In this case it's 1/6x.

Answer:

x = 6

Step-by-step explanation:

2x - 7 = 5​

=> 2x = 5 + 7

=> 2x = 12

=> x = 12 / 2

=> x = 6

Hope it helps :)

Answer:

x = 6

Step-by-step explanation:

2x - 7 = 5

→ Add 5 to both sides

2x = 12

→ Divide both sides by 2 to isolate x

x = 6

Answer:

Yes

Step-by-step explanation:

The volume is for example the area of a circle times the height. If you divide the volume of a cylinder by the amount the radius is squared multiplied by pi, to calculate its height.

Yes, there exists a linear relationship between the height and the volume.

A linear relationship is a relationship between the variables in a linear fashion. The relations ships can positive, negative, and neutral. Volume is a scalar quantity that is expressed in three-dimensional space.

Example of volume for the area of a circle is times the height. If we divide the volume of a cylinder by the amount of R it can be squared and multiplied by pi, to find its height.

Answer:

L= 24cm

W= 4cm

Step-by-step explanation:

Given data

Perimeter= 56cm

Area= 96cm^2

Let the width be x

W= x cm

L= 5x+4

P=2L+2W

56= 2(5x+4)+2x

56= 10x+8+2x

56-8= 12x

48= 12x

x= 48/12

x= 4cm

L= 5x+4

L= 5(4)+4

L= 20+4

L= 24cm

Answer: 60,000 tiles

Step-by-step explanation:

First find the area of the mural.

= 3 * 2

= 6 m²

The find the area of the tiles.

= 1 * 1

= 1 cm²

I m² = 10,000 cm²

There is therefore:

= 6 * 10,000

= 60,000 cm²

That is the area that needs to be covered in cm²

Seeing as each tile is 1cm², the number of tiles needed is:

= 60,000 / 1

= 60,000 tiles

Answer: the answer is 60,000 tiles

by the way that kinda seems like a lot of tiles to place like how long is that gonna take.

Answer:

It will cost 72 dollars to fence the perimeter

Step-by-step explanation:

First of all, we will have to make sure that we are working with the same units.

To do this, we will have to convert our units which are given in feet to inches.

1 foot = 12 inches

24 feet = 288 inches.

We now have the total length of what he needs to be 288 inches.

The fence costs 0.25 dollars per inch.

Therefore 288 inches will cost 0.25 X 288 = $ 72
