Answer:

Therefore, the table of ordered pairs that represents a proportional relationship is Table 2.

Step-by-step explanation:

The ratio of Y to X is 1/-1 = -1, 3/-3 = -1, and 5/-5 = -1. Since the ratio is constant (-1), Table 2 represents a proportional relationship.

Answer:

B

Step-by-step explanation:

You cross multiply the numbers in each table. The table that has equal answers is proportional. In the table for choice B, you can tell the table is proportional since -1 x 3 = -3 x 1

Answer:

22 square units.

Step-by-step explanation:

The area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.

To solve for the area of the figure, we can split the figure into 3 shapes. (2 triangles and a rectangle)

An expression you can use to solve for the area of a rectangle and the area of a triangle is:

Solving for the triangle on the left:

Solving what is in the parenthesis:

Therefore, the triangle on the left has an area of 6 square units.

To solve for the rectangle in the center, we can use this expression:

Therefore, the area of the rectangle in the center is 12 square units.

Solving for the triangle on the right:

Solving what is in the parenthesis:

Therefore, the area of the triangle on the right is 4 square units.

Adding all of the areas together:

Therefore, the total area of the shape is 22 square units.

As you can see in the diagram, the triangular prism has the following faces:

1) Two triangular faces

2) Three rectangular faces.

Surface area is the SUM of the areas of all of the faces.

Let us find these faces one by one:

1.

As you know, the area of the triangle is:

[tex]\frac{1}{2}* base*height[/tex]

Since, the base = 6 inches, and height = 4 inches;

Therefore, The area of ONE triangle = (1/2) * 6 * 4 = 12 inches squared.

In triangular prism, there are two triangles, therefore,

Two triangular faces = 2 * 12 inches = 24 inches squared --- (A)

2.

Now let us find the areas of three rectangular faces...

Since, two of the three rectangular faces are the same, therefore, we would find the area of one rectangular face, and multiple the result with two to get the total area of two rectangular faces.

Area of one rectangular face = base * height.

Since, base = 0.5 inches, height = 5 inches, therefore,

Area of one rectangular face = 0.5 * 5 = 2.5 inches squared.

Now that we have one rectangular face, therefore,

Area of two rectangular faces  = 2 * 2.5 = 5 inches squared.

The area of the third rectangular base = 6 * 0.5 = 3 inches squared

Therefore,

The area of the three rectangular faces = 5 + 3 = 8 inches squared --- (B)

Now add both "area of two triangular faces(A)" and "area of three rectangular faces(B)" to get the final surface area of the triangular prism.

Surface Area of the triangular prism = Area of Two Triangular faces + Area of Three Rectangular faces

Surface Area = 24 + 8 = 32 inches squared

The surface area of the triangular prism = 32 inches squared.

The correct option is: C

Answer:2200 gallons an hour

Step-by-step explanation:

55,000 ÷ 25 = 2,200 gallons an hour

2,200 gallons per 1 hour

55,000÷25=2,200

if 2,200 gallons leaks out every one hour, after 25 hours 55,000 gallons would be gone.

Answer: 3293

Step-by-step explanation: just multiply 365 by 9 then add 8

Answer:

3293

Step-by-step explanation:

multiple 365 by 9 then add 8

53°

Angle X + Angle 2x + 21 = 180. [ LINEAR PAIR ]

Angle 3x + 21 = 180

Angle 3x = 180 - 21 [ Transposing 21 over to RHS ] ( addition becomes subtraction)

Angle 3x = 159

Angle x = 159 ÷ 3. [ Transposing 3 over to RHS ] ( Multiplication becomes divison)

Angle x = 53°

You place the labels where the erosion goes.

Step-by-step explanation:

In the desert, the erosion would be wind. In the rock on the ocean is water. The red triangle thing is gravity. The grass with the little stream is water and the other brown grass rock looking thing in the upper right is ice. Or atleast I think, hope this helps.

a. To calculate the interest earned in 30 years, we can use the simple interest formula:

Simple interest = Principal * Rate * Time

Here, the principal (P) is $3,000, the rate (R) is 1.9%, and the time (T) is 30 years.

Simple interest = $3,000 * 0.019 * 30 = $1,710

Therefore, the customer will earn $1,710 in interest over 30 years.

b. To calculate the account balance after 30 years, we can add the interest earned to the principal:

Account balance = Principal + Interest

Account balance = $3,000 + $1,710 = $4,710

Therefore, the account balance will be $4,710 after 30 years.

Answer:

The colonists fought the British because they wanted to be free from Britain. They fought the British because of unfair taxes. They fought because they didn't have self-government. When the American colonies formed, they were part of Britain.

Step-by-step explanation:

Answer: they were fighting because they wanted their own independence they were fighting for themselves and they were also fighting so they could have their own rights and not have to pay the taxes that were high and so they didn't have to house British soldiers in their own homes.

Answer:

A. x > 14

Step-by-step explanation:

Answer: A

Step-by-step explanation:

First, its important to realize that x= the number of books the reads. We put a 10 in front of the x because for every 1 books she reads, she receives 10 points. If she needs 190 points total, and already has 50 points, we then need to find how many points she needs to get to 190. To find this, we subtract 50 from 190, and are left with 140 points remaining to reach 190.

10x+50>190

      -50  -50

10x>140

now that we know that 10x needs to be greater than 140, we can solve. We can divide both sides by 10 in order to find that x>14. She needs to read more than 14 books in order to earn the grand prize

[tex]\frac{10x > 140}{10}[/tex] = x>140

Answer: 75

Step-by-step explanation:

Add the values given in the table

16+15+20+14+15 = 80

Yellow happens 20 times out of the 80 times total.

The experimental probability of yellow is 20/80 = 1/4 = 0.25 = 25%

If we do 300 trials, then we predict yellow to happen 0.25*300 = 75 times.

Answer:

1634.77

Step-by-step explanation:

2πr= circumference

80.89=2πr

80.89/ πr= r

r= 12.87

area= πr^2

area= 12.87 π^2

area= 1634.77

Answer:

520.89 cm²

Step-by-step explanation:  

IN GIVEN QUESTION

The hubcap of the tire's circumference is 80.89 centimetres.

We must determine the radius of this hub cap, which we can do by using the circumference method to determine its area

now :

2πr = 80.89 cm

r = 80.89/ 2× 3.14

r = 12. 88 cm ( approx)

Area of hub cap = πr²

Area = 3.14 ×12.88² = 520.89 cm²

Answer:

90yrds^2

Step-by-step explanation:
First, let's find our area.
Area of a 2d rectangle is l(w). so 15(18) which in this case is 270ft.
Now that we have our area, we have to convert 270ft into yards.

A yard is equivalent to exactly 3ft. So let's use division to convert!
270/3 = 90.

Therefore, we need 90yrds^2 of carpet.

Answer:

2 or 3

Step-by-step explanation:

18 feet = 2 square yards

or if you

add 18 and 15 you get 33

33 feet = 3.6 square yards
