Marcy charges $575 per month to rent a room at her eight-room apartment complex. Running the complex costs

Marcy $9,880 per year in upkeep. Assuming that all of the rooms are rented out, how much does Marcy make from

her apartment complex every year?

a. $55,200

b. $45,320

c. $65,080

d. $16,780

### Answers

**Answer:**

**B**

**Step-by-step explanation:**

575 x 8 = 4600

4600 x 12 = 55200

55200 - 9880 = 45320

Therefore, our answer is B

The **amount** Marcy makes from her apartment complex every year is

$45,320

Option B is the correct answer.

What is an expression?

An **expression** isa way of writing a statement with more than two variables or numbers with **operations** such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Charge of a room per month = $575

Number of rooms = 8

Now,

All the **rooms** are rented.

1 year = 12 months.

The **total** **amount** charged in a year.

= 8 x 575 x 12

= $55,200

Now,

$9,880 is **upkeep**.

This means,

The **amount** **made**.

= 55,200 - 9,880

= 45,320

Thus,

The **amount** **made** is $45,320.

A 1/800 scale model (1 cm=800 cm) of the aircraft carrier USS Eisenhower is 42.2 cm long and 8.2 cm wide at the widest point of the deck. What are the actual length and width of this ship in METERS?.

### Answers

**Answer:**

*The actual length of the ship is 337.6 m*

*The actual width of the ship is 65.6 m*

**Step-by-step explanation:**

Scaling

The scale model of the aircraft carrier USS Eisenhower is 42.2 cm long and 8.2 cm wide when using the scale factor of 1 cm=800 cm.

Since we are required to express the real measures in meters, the scale factor is 1 cm = 8 m.

**The actual length of the ship is:**

**42.2*8=337.6 m**

**The actual width of the ship is:**

**8.2*8=65.6 m**

A cafeteria made 28.5 liters of lemonade. How many gallons of lemonade did the cafeteria make? (1 gallon is approximately 3.8 liters)

### Answers

**Answer:**

7.5 gallons

**Step-by-step explanation:**

We know that 1 gal = 3.8 L, and we have 28.5 L. So, set up a proportion:

1 gal / 3.8 L = x gal / 28.5 L , where x is the number of gallons the cafeteria made

Cross-multiply:

1 * 28.5 = 3.8 * x

28.5 = 3.8x

Divide by 3.8:

x = 28.5 / 3.8 = **7.5 gallons**

The LA dodgers hit the most home runs in 2014. The number of Home runs accounted for 6% of the entire major league baseball home run count. if the dodgers hit 35 home runs, then how many did the rest of the league hit?

### Answers

**Answer:**

To answer the question, we will need to find the 6% (the home runs of the LA Dodgers) of 583 (the entire Major League Baseball home run count).

To do that, first we are going to divide 6% by 100% to convert it to a fraction and get rid of the percentage signs :

Now we can multiply our fraction by the entire Major League Baseball home run count to get the home runs of the Dodgers:

We can conclude that the LA Dodgers hit approximately 35 home runs.

The mean output of a certain type of amplifier is 102 watts with a standard deviation of 12 watts. If 63 amplifiers are sampled, what is the probability that the mean of the sample would differ from the population mean by less than 3.4 watts

### Answers

Answer:

0.97547

Step-by-step explanation:

Given That:

Mean (m) = 102

Standard deviation (σ) = 12

Sample size (n) = 63

Probability that sample mean would differ from Population mean by less than 3.4 watts

P(m - s < X < m + s)

P(102 - 3.4 < Z < 102 + 3.4)

Using the Z formula :

Zscore = (x - m) / (σ/√n)

x = 102 - 3.4 = 98.6 ; x = 102 + 3.4 = 105.4

Z = (98.6 - 102) / (12/√63) = −2.248888

P(Z < - 2.2488) = 0.012263 (Z probability calculator)

Z = (105.4 - 102) / (12/√63) = 2.2488886

P(Z < 2.2488) = 0.98774 (Z probability calculator)

0.98774 - 0.012263 = 0.97547

**y = 2x - 3**

**Step-by-step explanation:**

Take any tow point from the line

(x₁ , y₁) = (1 , -1) & (x₂ , y₂) = (0 , -3)

[tex]Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\[/tex]

[tex]= \frac{-3-[-1]}{0-1}\\\\=\frac{-3+1}{-1}\\\\=\frac{-2}{-1}\\\\=2[/tex]

m = 2 & (1, -1)

y - y₁ = m(x -x₁)

y - [-1] = 2(x - 1)

y + 1 = 2x - 2

y = 2x - 2 - 1

**y = 2x - 3**
