Answer:

A) Scale factor from A to B is 2

B) Length of left side is 3 and length of right side is 5.

Step-by-step explanation:

A) Length of the top side is 2.5 in A and is 5 in polygon B. 5/2.5 = 2, therefore scale factor is 2.

B) Because the scale factor is 2, each of the sides double while the angles stay the same. Therefore, the length of the side on the left is 3 and length of the side on the right is 5.

1.5 x 2 = 3

2.5 x 2 = 5

Part (a)

Divide the upper horizontal lengths of the two figures:

5/2.5 = 2

The scale factor is 2. This means figure B has side lengths twice as long compared to figure A.

Answer: Scale factor = 2

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

Part (b)

The missing side length seems to be the diagonal side of figure B. I'm not sure what's going on with the vertical side 89.4 as that should be 3 instead (since 1.5*2 = 3).

The diagonal side is 5 units long since we double 2.5 to get 5.

Answers:

vertical side = 3

diagonal side = 5

A pentagon has 3 congruent sides and 2 other congruent sides. The perimeter of the pentagon is 36 centimeters. The three long congruent sides are 2 centimeters longer than the two shorter congruent sides.

Let x = length of a short side
Let y = length of a long side

The system of equations can be used to represent the situation.

y = x + 2
2x + 3y = 36

What is the length of one of the shorter congruent sides?

Answers

Answer:

Length of one of the shorter congruent side is: 6 cm

Step-by-step explanation:

In order to find the length of congruent sides we have to solve the system of equations

Given systems of equation is:

y = x + 2

2x + 3y = 36

Putting y = x+2 in second equation

[tex]2x + 3(x+2) = 36\\2x+3x+6 = 36\\5x+6 = 36\\5x = 36-6\\5x = 30\\\frac{5x}{5} = \frac{30}{5}\\x =6[/tex]

As we know that x represents the shorter side, the length of short side is: 6 cm

Hence,

Length of one of the shorter congruent side is: 6 cm

Ava solved the compound inequality+7<-1 or 2x-129 for all possible values of x. Which graph represents
the solution set?

36 -30 -24 -18 -12 -6 06 12
-36 -30 -24 -18 -12 -6 0 6 12

Answers

Answer:

Step-by-step explanation:

To get the graph, we will need to solve each inequality differently

For the first one, we have that

x/4 < -1-7

x/4 < -8

x < -8 * 4

x < -32

For the second side;

2x-1 ≥ 9

2x ≥ 10

x ≥ 5

So we have two arrows facing different directions

On the left should be unshaded while the right hand side should be shaded

All tickets to a play have the same cost. A group bought 6 tickets and paid a total of $99. Write a multiplication equation that can be used to determine cost c in dollars for each ticket.

Answers

You can use the equation 6c= 99

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

The multiplication equation to determine the cost C in dollars of each ticket is C = 99 x 1/6.

The cost of each ticket is $16.5.

What is a unit rate?

It is the quantity of an amount of something at a rate of one of another quantity.

Example:

6 miles in 2 hours

0ne hour will be 3 miles.

We have,

6 tickets = $99

Divide both sides by 6.

1 ticket = 99/6

1 ticket = $16.5

The multiplication equation to determine the cost C in dollars of each ticket:

$C = 99 x 1/6

Thus,

The multiplication equation to determine the cost C in dollars of each ticket is C = 99 x 1/6.

The cost of each ticket is $16.5.

Step-by-step explanation:

I'm not sure, but considering that 3/2 = 1.5 I'm assuming that the rest is proportional as well. Therefore, making x=3 and y=2 (4/2=2 and 6/2=3)

Answer:

x = 3, y = 2

Step-by-step explanation:

the diagram shows two triangles that are similar (angle measures are equal and sides are proportional)

1.5 corresponds to 3; therefore, the ratio of sides is 1:2

'x' corresponds to 6 (x must be half of 6)

'y' corresponds to 4 (y must be half of4)

Find the coordinates of the points of intersection of the parabola y=x^2+3x-4 and the line y=2x+2

Answers

You can set the y values equal to each other and solve the system:

x^2+3x-4=2x+2
x^2+x-6=0
(x+3)(x-2)=0
x=-3,2

So, these are the x values of the intersection. To get the y values, you can just plug them back into either formula:

y=2(-3)+2
y=-4

y2(2)+2
y=6

So the coordinates are (-3,-4) and 2,6).

how many solutions can be found by the equation 3y+5-2y=11?

Answers

We can solve the equation to find it's number of solutions, but we already know it only has 1 solution because it is a linear equation (y is raised to the first power).

3y + 5 − 2y = 11
y + 5 = 11
y = 6

This confirms that there is only 1 solution.

Find the value of f(-6).

Answers

Answer:

f(-6) = 5

Step-by-step explanation:

We want to find the value of the graph when x = -6

Go to where x = -6 and the y value is 5

f(-6) = 5

Answer: f(-6) = 5.

The number inside f(-6) is just x. So, use your finger to find -6 on the x-axis. Then, trace your finger in a vertical line to find where the function crosses where x = -6. This will be f(-6). We can see that this is 5.

A square field has an area of 479² ft What is the approximate length of a side of the field? Give your answer to the nearest foot. Explain your response.

Answers

Answer:

≈ 22 ft

Step-by-step explanation:

The area (A) of a square is calculated as

A = s² ( where s is the side length )

Given A = 479, then

s² = 479 ( take the square root of both sides )

s = [tex]\sqrt{479}[/tex] ≈ 22 ft ( to the nearest foot )

Answer:

A = 479 sq ft

479 = x²

square root of 479 = square root of x²

21.89 = x

rounded= 22 ft
