Just divide 100% by 80% and multiply that answer by 5. I'm pretty sure that's how you do it.

Question

The Mulraney's home has 2,550 square feet of living space. A contractor is building an addition to their home that will increase the square footage by 8%. What will be the square footage of their home with the addition?

Solution 1

First we have to find out how much the Mulraney's square footage increases with the addition. To do this, we should multiply the percent of expansion, 8% (0.08) by their current square footage (2, 550)

0.08 * 2,550 = 204

This means that the addition is adding 204 square feet to the Mulraney's house.

To find the total number of square footage, we just add the original (2,550 feet) to the addition (204).

2,550 + 204 = 2754

Therefore,**the square footage of the Mulraney's home with the addition is 2754 square feet.**

0.08 * 2,550 = 204

This means that the addition is adding 204 square feet to the Mulraney's house.

To find the total number of square footage, we just add the original (2,550 feet) to the addition (204).

2,550 + 204 = 2754

Therefore,

You have to find x then add 13

Question

The product of two numbers is 24 negative if one of the factor is -6 what is the other factors

Solution 1

The other factor is 4 because if you multiply a negative with a positive, you'll get a negative. -6 * 4 will give you - 24.

Question

Find the product of two numbers whose sum is 11 and difference is 3.

Solution 1

The **two numbers** are **7 **and **4**

Let the first number = x

let the second number = y

The sum of the numbers is 11, in algebra form x + y = 11

The difference of the two numbers is 3, in algebra form, x - y = 3

To obtain the two **unknown numbers**, we solve the two equations;

from the first equation, x = 11 - y

substitute the value of x into the last equation;

(11 - y) - y = 3

11 - y - y = 3

11 - 2y = 3

2y = 11 - 3

2y = 8

y = 4

The value of x = 11 - 4 = 7

Thus, the **two numbers** are **7 **and **4**

Solution 2

All you would do is minus what you have, like 11-3= 8 which would be 8+3=11 and 11-8=3 which means now you have the sum of 11 and the difference of 3.

Question

Runyon Company sells T-shirts ($5) and shorts ($6). If total sales were $1,040 and people bought 4 times as many T-shirts as shorts, what was the total number of T-shirts and shorts sold

Solution 1

You answer would be **4,160 **and you get the answer by multiplying 1,040 and 4 and you get **4,160**

Question

during a flu epidemic,146 students out of 680 who attend Lincoln middle school were absent. what percent were absent?

Solution 1

21% were absent, if you divide 146 by 680 and multiply by 100, then round to the nearest whole number, you get 21

Question

Lara solved an equation incorrectly, as shown below: Step 1: 2x = 18
Step 2: x = 18 − 2
Step 3: x = 16
Which statement best explains why Step 2 is incorrect in Lara's solution?
A) She did not divide 18 by 2.
B)She did not add 2 to 18.
C)She did not multiply 18 by 2.
D) She did not multiply 18 two times.

Solution 1

We have been given the steps to solve the equation as

Step 1: 2x = 18

Step 2: x = 18 − 2

Step 3: x = 16

There is an error in step 2.

We have

x is in multiplication with 2. So in order to get rid of 2 from the left hand side, we perform opposite operation of multiplication i.e. division.

So we must divide both sides by 2.

**Therefore, A is the correct option.**

**A) She did not divide 18 by 2.**

Solution 2

The answer is b. 18/2=9

Question

What number is 21% of 450

Solution 1

Since percent means per hundred, you are basically asking how many is 21 per hundred of 450.

To calculate 21 of 450, we solve the the problem by using the following formula: (X*Y)/100 where X=21 and Y=450.

Thus, when we enter 21 and 450 into our formula, we get this:

(21*450)/100 = answer

First we multiplied 21 by 450 and then we divided that by 100. When we did this, we found the answer to be 94.5.

Therefore, 21 percent of 450 is 94.5.

Therefore, 21 percent of 450 is 94.5.

Solution 2

The answer would be 94.5

21% of 450 is 94.5

21% of 450 is 94.5

Question

PLEASE HELP !Barry has an ice tray that makes ice cubes shaped like a cone with a diameter of 2 cm and height of 2 cm. To the nearest cubic centimeter, what is the volume of an ice cube from Barry's tray? 2 cm³ 8 cm³ 25 cm³ 101 cm³

Solution 1

To the nearest cubic centimeter, the volume of an ice cube would be 2 cm³. The formula for a cone is πr²(h/3), and when you divide the diameter by 2, you get one, so the formula would turn into π1²(2/3), giving you the answer.
