Answer:

Regular

Step-by-step explanation:

The answer to this question is a regular tessellation. A regular tessellation can be explained as a cover design of the plane which is done by making use of 1 type of regular polygon.

In order To make a regular tessellation, we have to make sure that the internal angle of the polygon can divide 360. This way there won't be gaps.

Answer: regular

Answer:

First two boxes are 6

Third box is -18

the last row is 3/1 (-18/1) = (1/3a) 3/1

Step-by-step explanation:

Ima try my best to explain:

-6 = 12 + 1/3a

+6    +6        

0 = 18 + 1/3 a    subtract 18 on both  in order to get 1/3a by itself

-18   -18

-18 = 1/3a          

-18/ 1/3  = 1/3a / 1/3 to make it easier multiply by the reciprocal on both sides

3/1 x -18/1 = 1/3 x 3/1      

multiply across will get you -54/1 which is just -54

Answer:

No

Step-by-step explanation:

Because it can be expressed as the quotient of two integers: 88 ÷ 1.

Answer:

No. 88 Is not an irrational number. The reason? It can only be expressed as 88 ÷ 1. Thus resulting in not being a irrational number.

Answer:

110

Step-by-step explanation:

They are equal to each other.

23x-5= 21x +5

2x = 10

x = 5

21(5) +5 = 110°

23(5) -5 = 110°

So it works. Angles are 110°

Answer:

120

Step-by-step explanation:

so we have 16 teams and we are chosing two

so this formula is called the chose formula

and the formula is 16*(16-1)/2!=16*15/2=120

Answer:

43

Step-by-step explanation:

you plug in the values

3m^2 + 2p^2 - 15

= 3(3)^2+2(10)^2-15

= 3×9+2×100-15

= 27+200-15

= 227-15

= 212

Just subtitute the value of m and p to the equation

Problem 3

Explanation: The angles opposite the congruent sides, are congruent angles. We consider these the base angles. This triangle is isosceles.

==================================================

Problem 4

Explanation:

Refer to the diagram below. Note how I've added in the variable y and marked another angle as 53 degrees which is one of the base angles of the left triangle. The base angles of the triangle on the right are y degrees each. Also, note the vertical angles both are y.

For the left triangle, the three angles add up to 180 which means we can solve for y to go from 53+53+y = 180 to y = 74

Then the interior angles of the triangle on the right has the three angles (y,y,x) add to 180 as well. So we have y+y+x = 180 which turns into 74+74+x = 180. That solves to x = 32

==================================================

Problem 5

Explanation:

Refer to the diagram below. I've added another base angle x, and the angle 90-x is complementary to this. This is because the two pieces must add to 90.

For the triangle on the bottom, the two base angles 74 and 74, add to the third angle 90-x and we would get 180. So we solve 74+74+(90-x) = 180 to get x = 58

Answer:

3. x = 47

4. x = 32

She can make five bcs she can

An expression that represents the given calculation is (450 + 348) × 7

The correct answer is an option (B)

"It is a combination of numbers, variables and some mathematical operations."

It is an acronym and it stands for Bracket , Order , Division , Multiplication , Addition and Subtraction .

In this question ,

its been said to first add then multiply

First add 450 to 348

(450 + 348)

now multiply the result with 7

(450 + 348  ) × 7

Therefore, an expression that represents the given calculation is (450 + 348) × 7

Answer:

Step-by-step explanation:

a) The circumference of the circle is given by ...

  C = πd

  C = (3.14)(5.5 mi) = 17.27 mi

The distance around the lake is about 17.27 miles.

__

b) The area is given by ...

  A = πr^2 . . . . . where r = d/2

  A = (3.14)(2.75^2) ≈ 23.75 . . . . square miles

The surface area of the lake is about 23.75 square miles.

If you use a more exact value of pi (the "pi button" for example), then the hundredths digit increases by 1 in each case: 17.28, 23.76.

Answer:

The maximum height of the ferris wheel is 64 ft.

The radius of the ferris wheel is 30ft.

Step-by-step explanation:

i took the test :)

True statements are:

'The car makes a complete revolution in 5 s.'

'The maximum height of the Ferris wheel is 64 ft.'

'The radius of the Ferris wheel is 30 ft.'

An amusement ride consisting of a rotating upright wheel with multiple passenger-carrying components attached to the rim in such a way that as the wheel turns, they are kept upright, usually by gravity is called a Ferris wheel. Wheel is of circle shape having axle joint to the rim with spikes.

Given table

Time (seconds) Height (feet)

0                          34

2.5                       64

5                          34

7.5                         4

10                         34

12.5                      64

15                         34

17.5                         4

20                        34

statements,

a) The car makes a complete revolution in 5s,
It's true, because the car reaches at the same height in every 5 seconds.

b) The maximum height of the Ferris wheel is 64 ft,

it's true, because observing the table, maximum height is 64 ft.

c) Radius of the Ferris wheel = 30 feet,

It's true because, the height of the car is 4 feet and it achieves maximum height = 64 feet

Diameter of wheel = 64 - 4 = 60 ft

Radius = 60/2 = 30 ft.

d) If the car is loaded at 0 s, then people are loaded at the lowest point of the Ferris wheel.

It's false because the lowest point is 4 ft. but at 0 second height is 34 feet.

Hence, statements,

'The car makes a complete revolution in 5 s.'

'The maximum height of the Ferris wheel is 64 ft.'

'The radius of the Ferris wheel is 30 ft.'

are true.
