Answer 1

Answer:

16

Step-by-step explanation:

Line 1: ◄ + ◄ + ◄ = 30

3◄ = 30

◄ = 10

The triangle equals 10.

Line 2: ◄ + ◘ + ◘ = 18

10 + 2◘ = 18

2◘ = 8

◘ = 4

The square equals 4.

Line 3: ◘ - ○ = 2

4 - ○ = 2

-○ = -2

○ = 2

The circle equals 2.

○ + ◄ + ◘ = 2 + 10 + 4 = 16

Answer: 16

Answers

Answer:

it`s 5

Step-by-step explanation:

x is unknown, but it`s multiplied by 6 and by 5, so it`s 30, then space x again, which you need now to divide the opposite way. 30 / 6 = 5x

So, the answer is 5x, easy

Answers

Answer:

18 square yards of rubber flooring

Step-by-step explanation:

We can look at the model as a 16x13 rectangle with a 6x9 rectangle cut out of it. So we can just find the area of the 16x13 rectangle and subtract the area of the 6x9 rectangle:

16*13=208

6*9=54

208-54=154

So the area of the floor is 154 square feet.

BUT the problem asks how many square YARDS of rubber flooring are required to cover the floor. Because there are 3 feet in a yard, there are 3^2 square feet in a square yard, or 9 square feet in a square yard. So we need to divide 154 by 9, which is 17 1^9. Because you can only buy 1 square yard of rubber flooring at a time, we need to buy 18 yards of rubber flooring to cover the floor.

I hope I explained this well enough. Happy mathing!

Edit: I just stood up too fast. The second picture is VERY true.

Answer:

154 ft.^2

Step-by-step explanation:

13 times 16 = 208

6 times 9 = 54

208 - 54 = 154

A map of a highway has a scale of 2 inches =27 miles. The length of the highway on the map is 9 inches. There are 7 rest stops equally spaced on the​ highway, including one at each end. You are making a new map with a scale of 1 inch=30 miles . How far apart are the rest stops on the new​ map?

Answers

Answer: 0.675 inches apart

Step-by-step explanation:

27/2=13.5

7 spots-1 spot( because one is on the end of the map at 0)

9/6=1.5

1.5•13.5=20.25

20.25/30=0.675

Vertical angles are congruent.

9 Pencils cost $7.74
Which equation would help determine the cost of 6 pencils?

Answers

Answer: $5.16

Explanation: (in my way)
x= 6x7.74/9
Multiply 6 x 7.74
x=46.44/9
Divide
x=$5.16
$7.74 divided by 9 equals $0.86 per pencil. so 6 pencils would be 6 times 0.86 which equals $5.16 for 6 pencils.

(7.74 / 9) • 6 = Cost of 6 pencils

In the figure below, DOG, ION, and IDO are congruent and isosceles, each with perimeter 55. The quadrilaterals FLIN, DIES, and DRAG are all squares. The perimeter of the 11-sided polygon DRAGONFLIES is 127.

What is the area of DRAG?

Answers

Let's call the sides that are length  DG " s " .

And let's call the sides that are length  GO  " t ".

Since the perimeter of each triangle is 55...

s + t + t  =  55

s + 2t  =  55

2t  =  55 - s

Since the perimeter of the entire figure is 127...

9s + 2t  =  127            

Since  2t = 55 - s  ,  we can replace  2t  with  55 - s .

9s + (55 - s)  =  127

8s + 55  =  127             Subtract  55  from both sides.

8s  =  72                       Divide both sides by  8  .

s  =  9

And...the area of the square DRAG  =  DG2  =  s2  =  92  =  81 sq. units.

A cell phone provider offers a plan that costs ​$40 per month plus ​$0.10 per text message sent or received. A comparable plan costs ​$60 per month but offers unlimited text messaging. If you send or receive an average of 50 text messages each​ month, which plan would you​ choose? Why?

Answers

Okay so $40 a month, 10 cents per message.

10 cents times 50 messages is only 5 dollars.

So, it would be around $45 a month.

If I only sent around that many messages a month, I would just go with the $40 a month, cause you can save around $15.
