Peter receives a $30000 salary for working as an engineer. If Peter spends 20% of his salary on expenses each year, then how much money does Peter have to spend on expenses?Identify the part, percent, and whole. Then solve with the formula

Answers

Answer 1

Answer: If Peter spends 20% of his salary on expenses, and his salary is $30,000, then all we need to do is find 20% of 30,000.

We can do this by converting 20% to a fraction or decimal. We'll do fraction because I think it is easier to see.

20% = 20/100 = 2/10 = 1/5

So we need to find 1/5th of 30,000

1/5 x 30,000 = 30,000/5 = 6,000

Therefore, Peter has $6,000 to spend on expenses.

Answer 2

Answer: Peter has $6000 to spend on expenses. You have to multiply 30000 time .20(the decimal form of 20%).

StartFraction 1 over 1.55 EndFraction = StartFraction x over 3.5 EndFraction
StartFraction x over 1.55 EndFraction = StartFraction 1 over 3.5 EndFraction

Answers

Answer:

StartFraction 1.55 over 1 EndFraction = StartFraction x over 3.5 EndFraction

Step-by-step explanation:

$(1.55)/(1) = (x)/(3.5) \n \n \therefore \: x = 1.55 * 3.5 \n \n \therefore \: x = \$ 5.425 \n \n\therefore \: x\approx \$5.43$

Answers

We simplify 10q-13-5q=12 to 5q-13=12. Now, we add 13 to both sides, 5q-13+13=12+13. We should get 5q=25. Finnally, we divide both sides by 5, 5q/5=25/5, Therefore, the answer is q=5

You have $23 when you go out to dinner. You want to save $5 for dessert. Which inequality represents the amount of money, s, you can spend before dessert?A. 23-s ≥ 5
B. 23-s >5
C. 5D. s ≤23+5

Answers

The inequality is 23-s≥5 so, option A is correct.

What is inequality?

Inequality is the relationship between two expressions such that those expressions are not equal.

A person spend $s on the food. Determine the amount left for the dessert.

23-s

The amount left should be greater than or equal to $5 so that a person can purchase dessert.

If x^(2) - 2 = 2^(2/3) + 2(-2/3) prove that x = 2^(1/3)+2^(-1/3)

Answers

Step-by-step explanation:

x² - 2 = 2^(2/3) + 2^(-2/3)

x² = 2^(2/3) + 2 + 2^(-2/3)

x² = (2^(1/3))² + 2 × 2^(1/3) × 2^(-1/3) +

(2^(-1/3))² (It is in the form of a²+2ab+b²)

x² = (2^(1/3) + 2^(-1/3))²

x = 2^(1/3) + 2^(-1/3)

Answers

7 x a = 8 x 10 - 31
7 x a = 80 - 31
7 x a = 49
a = 49/7
a = 7

7*a = 8*10 - 31. We perform the multiplication first.

7a = 80 - 31

7a = 49

a = 49/7

a = 7

lu a = 7
