Answer:
### What is the percentage?

The** number is 442 **which is obtained after decreasing 520 by 15% **the answer is 442.**

It's the **ratio **of **two integers **stated as a fraction of a **hundred parts**. It is a metric for comparing **two sets **of **data**, and it is **expressed **as a **percentage **using the **percent symbol**.

**Let x be the number that is obtained after decreasing 520 by 15%**

**= (100 - 15)% of 520**

= 85% of 520

= 0.85×520

**= 442**

Thus, the** number is 442 **which is obtained after decreasing 520 by 15% **the answer is 442.**

Answer:

Answer:

442

Step-by-step explanation:

If you want to decrease 520 by 15%, you have to multiply 15% by 520 first, which is 78. Next, you have to minus 78 from 520. Now you get 442!

A mattress store sells only king, queen and twin-size mattresses. Sales records at the store indicate that the number of queen-size mattresses sold is one-fourth the number of king and twin-size mattresses combined. Records also indicate that three times as many king-size mattresses are sold as twin-size mattresses. Calculate the probability that the next mattress sold is either king or queen-size.

**Answer:**

A, B, and D.

**Step-by-step explanation:**

HEY!! remember that if a number has ^2, it basically means it's multiplied by itself. for example:

5^2 = 5 x 5

aka, 25.

You can use this to check each of the answers in your formula, like this:

if x=6, then:

x^2 < 100

6 x 6 = 36

36 < 100

A is one of your correct answers!

Also remember, if you multiply a negative by a negative, it becomes positive.

-5 x -5 = 25

-10 x -10 = 100

The answer to this is A, B, D.

**Answer:**

100

**Step-by-step explanation:**

because 10×100=1000

**Answer:**

100 of the $100 bills equals to $1000

**Step-by-step explanation:**

1000/100=100

**Step-by-step explanation:**

given a slope and a point that the line passes through you have 2 options

Option 1: Solve for the equation of the line so you can just use that to graph the line. In this scenario it would be y=(-5/2)x - (20/13)

Option 2: plot the given point and, based on the slope, plot the next point that it crosses. In this case the next point would be (5, 7). Then you can just draw a line using these 2 points.

**Answer:**

**(c) 0.46 million**

**Step-by-step explanation:**

As provided immediate cash outlay = $8 million.

This will represent cash outflow at period 0, as it is made immediately, no time period has lapsed.

Cash inflows as provided and the respective present value factor are:

Year Cash Inflow Factor Discounted Value

1 $3 million 0.9091 $2,727,300

2 $4 million 0.8264 $3,305,600

3 $2 million 0.7513 $1,502,600

Total present value of cash inflow = $7,535,500

Therefore, net present value = $7,535,500 - $8,000,000 = - $464,500

That is - 0.46 million

Correct option is

**(c) 0.46 million**
