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%

Was gonna brute force every question with a calculator but luckily A was correct. Substituted 25 for x and found all the angles. 5x was 125, which I subtracted from 180 to find the interior angle, 55°. 3x was 75.

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

**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).

Write an equation of the line with a slope of -3/4 and y-intercept of -6

Answers

Answer:

Hi there!

Your answer is:

y= -3/4x -6

Step-by-step explanation:

The y int is the constant.

The slope is the coefficient of the X

Hope this helps!

The equation of the line with a slope of -3/4 and y-intercept of -6 is; 4y + 3x = -24.

The slope-intercept form of the equation of a straight line usually takes the form;

y = Mx + c

where; m = slope and c = y-intercept

Therefore; the equation of the required line is;

y = (-3/4)x + (-6)

4y = -3x - 24

4y + 3x = -24
