What is the formula for the volume of a trapezoidal prism?

Answer:

7?

Step-by-step explanation:

72/10 squares = about 7

Answer:

x

Step-by-step explanation:

Answer:

l = 14

Step-by-step explanation:

The perimeter of a rectangle is

P =2(l+w)

The width is x-6

w = x-6

The length is 8 units longer than the width

l = w+8

l = x-6+8

l = x+2

We can substitute this into the equation for Perimeter, which is given as 40

40 = 2(x+2 + x-6)

Combine like terms

40 =2 (2x-4)

Divide by 2

40/2 = 2/2 (2x-4)

20 = 2x-4

Add 4 to each side

20+4 =2x-4+4

24 = 2x

Divide by 2

24/2 =2x/2

12=x

We want to know the length

l = x+2

l =12+2

l = 14

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Multiply the length that you have been given by 2

2: Then, subtract the result from the perimeter.

3: You now have the total length for the remaining 2 sides.

4: Width or height is the number divided by 2.

Answer:

75+8n

Step-by-step explanation:

$75 is the constant because that is the amount of money only paid once. $8 is the coefficient because it is multipled by the variable n. The variable is the amount of people going to the bowling alley.

Therefore, to determine the total cost, you need add $75 to the product of 8 and the number of people coming.

Answer:

Intersect/Solution at (1, -2)

Step-by-step explanation:

Equation 1: y = 3x - 5

Equation 2: y = 6x - 8

Step 1 Mutliply each side of equations one by -2

New Equation 1: -2y = -6x + 10

New Equation 2: y = 6x -8

Add the Equations: -y = +2

Multiply each side by -1 and you'll get that y = -2

Plug in -2 to either equation: -2 = 3x - 5

add 2 to each side 0 = 3x -3

add 3 to each side 3x = 3

divide by 3 and you'll get that x = 1

Part A:The solution of the pair of  the equation is,x=1 and y=- -2.

Part B:  If the two equations are graphed, at point (1,-2) will the lines representing the two equations intersect.

If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:

y = mx +c

A pair of equations is shown below:

y = 3x − 5 -------1

y = 6x − 8 --------2

Substitute the value of y from the equation 1 into equation 2;

3x − 5=6x − 8

3x=-5+8

3x=3

x=1

Put the value of x in the equation 1;

y = 3x − 5 -------1

y=3(1)-5

y=- -2

Hence,the solution of the pair of  the equation is,x=1 and y=- -2 and at point (1,-2) will the lines representing the two equations intersect.

Answer:

a, and e.

Step-by-step explanation:

x+6=5+x has no solution. When you subtract 6 from both sides, you get x=-1+x. We know that x doesn't equal -1+x, so this equation has no solution.

-2(x-3)=-2x+6 has a solution. When you distribute, you get -2x+6=-2x+6.

4-4x=3x+2 has a solution. Subtract 4 from both sides to get -4x=3x-2. Subtract 3x from both sides to get -7x=-2, then divide -2 by -7 to get x=0.285714285714. This equation has a solution.

4(x+1)=3(x+2) has a solution. Distribute to get 4x+4=3x+6. Subtract 4 from both sides to get 4x=3x+2. Subtract 3x from both sides to get x=2. This equation has a solution.

5-3x=-3x+4 has no solution. Subtract 5 from both sides to get -3x=-3x-1. We know that -3x does not equal -3x-1, so we can determine that this equation has no solution.

Answer:

a  and e has no solution

Step-by-step explanation:

A) x + 6 = x +5

Subtract x from both sides

   x + 6 - x = x + 5 - x

        6 = 5 which is not true.

So, this equation has no solution

d) 5 - 3x = -3x + 4

Add 3x to both sides

5- 3x + 3x = -3x + 4 + 3x

5 = 4         which is not true.

So, no solution

Answer:

Tiffany just got an aquarium for her rare turtle. She wants to fill it with water but it came without the volume measurement on it. She measures and finds aquarium's length is 30 inches, width is 12 inches, and height is 18 inches. How much many cubic inches of water does she need?

Step-by-step explanation:

Formula for right rectangular prism is Length×Width×Height

30×12×18 = 6480

So she needs 6,480 in³ of water

Answer:

28m⁷n⁵

Step-by-step explanation:

You would first multiply 14 by 2. You would then multiply (which is really addition when it comes to exponents) your like-term exponents.

(14m²n⁵)(2m⁵) =28m⁷n⁵

14(2) = 28

m² + m⁵=m⁷

n⁵ + 0 = n⁵

Answer:

[tex]28 {m}^{7} {n}^{5} [/tex]

Step-by-step explanation:

14*2=28; m^2*m^5=m^7.

When you're working with multiplication of powers, you have to add the exponents. For example

[tex] {x}^{4} \times {x}^{2} = {x}^{6} [/tex]

Because

[tex] {x}^{4} = x \times x \times x \times x \\ {x}^{2} = x \times x \\ {x}^{4} \times {x}^{2} = x \times x \times x \times x \times x \times x = {x}^{6} [/tex]

Step-by-step explanation:

The table is completed below.

We can say that the relationship between the scale factor and the area of scaled copies is proportional.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

Using the formula for the area of a triangle:

Area = 1/2 x base x height

With a base of 3cm and height of 2cm, the area of the original triangle is:

Area = 1/2 x 3cm x 2cm = 3cm²

To find the area of the scaled triangles, we can use the scale factor to determine the corresponding dimensions, and then calculate the area using the same formula.

Scale factor Corresponding dimensions Area

1                         3cm x 2cm               3cm²

2                         6cm x 4cm                12cm²

5                        15cm x 10cm               75cm²

s                        3s cm x 2s cm             3s² cm²

Now,

To see if the relationship between the scale factor and the area of scaled copies is proportional, we can calculate the ratio of the area to the scale factor for each row of the table:

Scale factor Corresponding dimensions Area Ratio of area to scale factor

1                             3cm x 2cm             3cm²          3/1 = 3

2                             6cm x 4cm             12cm² 12/2 = 6

5                                 15cm x 10cm      75cm² 75/5 = 15

s                            3s cm x 2s cm     3s² cm²  (3s²)/s = 3s

In each case, the ratio of the area to the scale factor is constant, which means that the relationship between the scale factor and the area of scaled copies is indeed proportional.

Therefore,

We can say that the relationship between the scale factor and the area of scaled copies is proportional.
