What is percentage of a number?

The percentage of a number represents a portion or fraction of the whole number expressed as a fraction of 100. It is often used to describe a proportion or rate out of 100.

To calculate the percentage of a number, you typically multiply the number by the desired percentage as a decimal or fraction. The result represents the portion or fraction of the number expressed as a percentage.

The formula for calculating the percentage of a number is:

Percentage = (Number * Percentage Value) / 100.

Substituting the values into the formula above;

percentage = (9 / 12) * 100

percentage = (3/4) * 100

percentage = 0.75 * 100

Percentage = 75%

Answer:

(2x+7)° + (5x+4)° + 69° = 360°

=> 2x + 7 + 5x + 4 + 69 = 360

=> 7x + 80 = 360

=> 7x = 360 – 80

=> x = 280/7

=> x = 40

Answer:

x=40

Step-by-step explanation:

(2x+7)*+(5x+4)*+69*=360*   (360* because its a circle)

7x+80=360       (combine like terms)

- 80     -80      (minus 80 both sides)

**pls help ASAP taking a test .

Answers

Answer:

C.  The value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days

Step-by-step explanation:

So 5 time 4 equals 20...!

80 minus 20= 60

The value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days, which is the correct answer would be option (C).

What is a numerical expression?

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

A student works 80 hours per month and plans to work 5 hours each day, but only on days when work is planned. After working for d days, the function / (d) - 80 — 5d shows the number of hours of work remaining for the month.

⇒ f (d) = 80 - 5d ....(i)

According to option (C),

Substitute the value of d = 4 in equation (i),

⇒ f (4) = 80 - 5(4)

⇒ f (4) = 80 - 20

⇒ f (4) = 60

Thus, the value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days

Hence, the correct answer would be option (C).

Santa Claus has been experiencing some recent back pain and is unable to carry large bags of toys over his shoulders. As a result he uses redex to deliver many of his gifts this year. Fedex charges a flat rate of $2.50 plus $0.85 per pound. If the cost of sending gifts to the Jones is $28.85, how much did their gifts weigh?

Answers

Answer: 31 pounds

Step-by-step explanation:

From the question, we are informed that Fedex charges a flat rate of $2.50 plus $0.85 per pound and that the total cost of sending gifts to the Jones is $28.85. This can be mathematically expressed as:

2.50 + 0.85p = 28.85

where p = weight of the gift

So we have to solve the equation

2.50 + 0.85p = 28.85

0.85p = 28.85 - 2.50

0.85p = 26.35

p = 26.35/0.85

p = 31

Therefore the weight of the gift is 31 pounds
