I need to know what two numbers add to equal -3 and multiply to equal -2650

Answers

Answer 1
Answer: 50 and -53

50 + (-53) = -3

50 x (-53) = -2650
Answer 2
Answer: - - To solve:

50 + -53 = -3

and 

50 * -53= -2650

Leaving your answers with 50 and 53, this is because they both add to -3 and multiply to -2650

A round barbecue pit is 2 meters in diameter. What is the distance around the barbecue pit? A. 3.14 meters
B. 12. 56 meters
C. 6.28 meters
D. 18.84 meters

Answers

The length of a circle is equal to 2π * diameter/2, where π = ~3.14. In our case we have 2*(~3.14) = 6.28 meters. So the correct answer is C.

Say that Thailand has a workforce of 35,709,487 people, each of whom earns an average salary of (equivalent USD) $8,630 annually. If the Thai government wants to raise $70 billion in tax revenue, approximately where should it set the income tax rate?

Answers

First we have to multiply the number of working people by their average annual salary: 35,709,487 * $8630 = $308,172,872,810. Then we have to calculate which percent of that sum represents $70,000,000,000. r = ( 70,000,000,000 / 308,172,872,810 ) * 100 = 22.7%. Answer; The income tax rate should be approximately 22.7%.

Answer:

c

Step-by-step explanation:The answer is c which is 23%

How do you express 43.7% as a decimal?

you move the decimal 2 spaces to the left and drop the percentage sign. a cool trick is to count when you do it. move the decimal once say "tens" then move it twice say "hundreds" same goes for thousands and so on. your answer should look like this  .437
or if rounded .44

The surface area of a cube is 1849 mm2. Which statements are true about the same cube measured in square centimeters?

Choose all answers that are correct.

A.The number representing the surface area would decrease.

B.The number representing the surface area would increase.

C.The actual surface area would decrease.

D.The actual surface area would increase.

E.The actual surface area would stay the same.

Answers

The correct statements are from letters A and E. The same cube when measured in square centimeters will still be the same cube. Only the number which represents the surface area will change and will decrease because the units are now in centimeters.  The surface area would be 184.9 cm^2. The actual surface area of the cube will still be the same.

Write an algebraic expression to represent each of these 6 verbal expressions.1. 7 less than fifteen times a number
2. the difference of nine times a number and the quotient of 6 and the same number
3. the sum of 100 and four times a number
4. the product of 3 and the sum of 11 and a number
5. four times the square of a number increased by five times the same number
6. 23 more than the product of 7 and a number

Answers

Answer:

1. 15n - 7

2. 9n - (6/n)

3. 4n + 100

4. 3(11 + n)

5. 4n^2 + 5n

6. 7n + 23

Step-by-step explanation:

1. "7 less than fifteen times a number" can be represented as 15n - 7, where n represents the unknown number. This expression means that you take the number, multiply it by 15, and then subtract 7 from the result.

2. "The difference of nine times a number and the quotient of 6 and the same number" can be represented as 9n - (6 / n), where n represents the unknown number. This expression means that you take the number, multiply it by 9, and then subtract the quotient of 6 divided by the same number.

3. "The sum of 100 and four times a number" can be represented as 4n + 100, where n represents the unknown number. This expression means that you take the number, multiply it by 4, and then add 100 to the result.

4. "The product of 3 and the sum of 11 and a number" can be represented as 3(11 + n), where n represents the unknown number. This expression means that you take the number, add 11 to it, and then multiply the sum by 3.

5. "Four times the square of a number increased by five times the same number" can be represented as 4n^2 + 5n, where n represents the unknown number. This expression means that you square the number, multiply the result by 4, and then add the product of the number and 5.

6. "23 more than the product of 7 and a number" can be represented as 7n + 23, where n represents the unknown number. This expression means that you take the number, multiply it by 7, and then add 23 to the result.
