**Answer 1**

**Answer:**

-3/5

**Step-by-step explanation:**

I used the KCF, or keep, change, flip, method for this.

The original problem is -2/5 divided by -2/3

We keep the first fraction - -2/5

change the sign to multiplication

and flip the second fraction - 3/2

so, -2/5 x 3/2

and then check for where we can simplify, we can in this instance:

-1/5 x 3/1

and then multiply across

-3/5

5. The cost per person to rent a chartered bus varies inversely to the number of people a who ride the bus. If 40 people pay $9.50 each to ride the chartered bus, what is the cost per person if only 25 people go?

the answers are

a. $24.50

b. $5.94

c. $15.20

d. $380.00

### Answers

Answer d $380.00 or answer a $24.00

The **cost per person **for 25 people is 15.20

How to determine the cost per person?

An **inverse variation **is represented as:

k = xy

Where:

k represents the **proportionality constant**y represents the **cost per person**x represents the **number of persons**

So, we have:

40 * 9.50 = 25 * y

Divide both sides by 25

y = 15.20

Hence, the **cost per person **for 25 people is 15.20

How can you use a sequence of transformations to map a preimage to its image?

### Answers

**Answer:**

You can use a sequence of two or more transformations to map a preimage to its image. You can map AABC onto AA"B"C" by a translation 3 units right followed by a 90° clockwise rotation about the origin.

A** sequence of transformations** to map a preimage to its image is **reflection.**

It is required to** find the transformations **to map a preimage to its image.

What are transformations?

A** transformation** is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the** transformation.**

Given:

Transformation maps the pre-image, DEFG, to the image, D'E'F'G'. The transformation is a reflection.

The line of reflection must go through the center point. Two lines of reflection go through the sides of the figure. Two lines of reflection go through the vertices of the figure. Thus, there are four possible lines that go through the center and are lines of reflections.

Therefore, a** sequence of transformations** to map a preimage to its image is **reflection.**

Answer:x=9

Step-by-step explanation:so this is a isosceles triangle so that means the two sides are equal so set up the equation as 3x-7=20. And by moving the 7 over it will be 3x=27 and then you want you separate the x and to do that you have to divide x and 27 by 3 and you answer is x = 9

Hey there!

3x - 7 = 20°

ADD 7 to BOTH SIDES

3x - 7 + 7 = 20 + 7

CANCEL out: -7 + 7 because it give you 0

KEEP: 20 + 7 because it help solve for the x-value

NEW EQUATION: 3x = 20 + 7

SIMPLIFY IT!

3x = 27

DIVIDE 3 to BOTH SIDES

3x/3 = 27/3

CANCEL out: 3/3 because it give you 1

KEEP: 27/3 because it help solve for the x-value

NEW EQUATION: x = 27/3

SIMPLIFY IT!

x = 9

Therefore, your answer is: x = 9

A coin is being flipped 400 times. What is the probability of it landing on heads at most 170 times, rounded to the nearest tenth of a percent?

"at most" is throwing me... what is the formula?

### Answers

Hello!

We have two probabilities we can use; we have 170/400, for our experiment, and 1/2, which is our theoretical probability.

To solve, we just multiply the two probabilities.

=0.2125≈21.3

Therefore, we have about a 21.3% chance of this event occurring.
