Answer:
### What is dilation?

The figures that are **scaled copies** of the original figure A include the following: B. 2 and 4.

A **dilation **is a type of transformation that is used for altering the dimensions of a geometric figure, but not its shape.

In Mathematics, the following rules are applied to interpret and understand the **dilation** of a geometric figure:

- A geometric figure is enlarged when the
**scale factor**is greater than 1. - A geometric figure remains the same when the scale factor is equal to 1.
- A geometric figure is reduced when the
**scale factor**is less than 1.

In this context, we can logically deduce that the **scaled copies** of the original figure A are figure 2 and figure 4 because dilation preserves angle measures and the direction that the shape faces.

Complete Question:

Here is a figure that looks like the letter A, along with several other figures. Which figures are scaled copies of the original A?

2 and 3

2 and 4

1 and 4

1 and 3

Answer:

**Answer:**

i think 2 and 4

**Step-by-step explanation:**

In a study of factors affecting whether soldiers decide to reenlist, 320 subjects were measured for an index of satisfaction. The sample mean is 28.8 and the sample standard deviation is 7.3. Use the given sample data to construct the 98 percent confidence interval for the population mean.

The machinist's goal was to increase his production by at least 10% each day. Assume he achieved his goal. If he was able to machine 25 items on Tuesday, how many would he machine on Wednesday?

Consider an unreliable communication channel that can successfully send a message with probability 1/2, or otherwise, the message is lost with probability 1/2. How many times do we need to transmit the message over this unreliable channel so that with probability 63/64 the message is received at least once? Explain your answer. Hint: treat this as a Bernoulli process with a probability of success 1/2. The question is equivalent to: how many times do you have to try until you get at least one success?

Six-four million, one hundred eighty-six thousand, three hundred square miles in standard form

Two parallel lines are crossed by a transversal.What is the value of x?Could someone tell me how to solve this?

Based on the available information, and options in the question, the total **change** in the gift card balance after 3 weeks is **option A.** -$17.61

Evaluation in Mathematics is a method that is used to find the value of the expression when the **variable** is replaced by a given number.

In this case, to find the total change in the gift card balance after 3 weeks, calculate the total amount spent on **gourmet** coffee during this period.

Given that Sonia purchases a **$5.87** gourmet coffee each week the total amount spent on coffee after 3 weeks can be calculated as follows:

Total amount spent = cost per coffee * number of weeks

= $5.87 * 3

= **$17.61**

Therefore, Sonia will have spent a total of $17.61 on gourmet coffee after 3 weeks, which will be **$-17.61** of the top change in the gift card.

Hence, in this case, it is concluded that the correct answer is **option A**. -$17.61

you just divide 1.5 by a 100

**Answer:**

(-2.2, -1.6), (3, 1)

**Step-by-step explanation:**

You don't have to go far to find the equations. They are right there in your problem statement. Perhaps you want to find the solutions to the equations.

Use the first equation to write an expression for x, then substitute that into the second equation:

x = 2y +1

y^2 -3(2y+1)(y) +8 = 0

-5y^2 -3y +8 = 0

-(5y +8)(y -1) = 0

y = -8/5 or y = 1

The corresponding values of x are ...

x = 2(-8/5)+1 = -11/5

x = 2(1) +1 = 3

**The solutions are (x, y) = (-2.2, -1.6) and (3, 1)**.

As given by the question

There are given that the inside edge is 4 in.

Now,

Since sphere fits snugly inside a cube therefore diameter of sphere will be equal to side of the cube

So,

Then,

Volume of the sphere is given by:

And,

The volume of a cube is:

Then,

The volume of the space between the sphere and cube = 64-33.5 = 30.5.

Hence, **the answer is 30.5 cube inches.**
