Marco pays $1008  for for his credit card, groceries, and rent.

percentage, a relative value indicating hundredth parts of any quantity.

Given that Marco budgets $1,600 a month for expenses.

According to the graph he pays 4% of credit card

Now let us find 4% of 1600

4/100×1600

0.04×1600

$64 Marco pays for credit card.

From graph, he pays 17% for groceries

17% of 1600

17/100×1600

0.17×1600=$272

$272 Marco pays for Groceries.

From graph, he pays 42% for rent

42/100×1600

0.42×1600=672

$672 Marco pays for Rent.

Hence, Marco pays $1008  for for his credit card, groceries, and rent.

Answer: The total amount Jennifer will owe to the bank on January 31st is $3,458.75

Step-by-step explanation: In September, Jennifer Rick went to Park Bank to borrow $2,500 at 11.75% interest for 4 months. As this loan is a simple interest loan calculated monthly, we need to calculate the total amount she will owe to the bank on January 31st.

We use the formula for simple interest which is:

Interest = Principal x Interest rate x Time

Interest = $2,500 x 11.75/100 x 4/12 = $958.75 (rounding to the nearest cent)

Now we can add the interest to the principal amount to get the total amount that Jennifer will owe to the bank on January 31st.

Total amount = Principal + Interest

Total amount = $2,500 + $958.75 = $3,458.75 (rounding to the nearest cent)

So, the total amount Jennifer will owe to the bank on January 31st is $3,458.75

The equation that can be used to determine the total cost, given the number of movie tickets, is c = 8. 50 c

The equation that shows the total cost when you buy a certain number of tickets, can only be found after you solve for the ticket price.

The ticket price is :
= Cost of tickets / Number of tickets

= 42. 50 / 8

= $ 8. 50

The equation for the total cost would therefore be:

Total cost = Number of tickets x Cost per ticket

c = f x 8. 50

c = 8. 50 f

Answer:

600 ml

Step-by-step explanation:

One of the rules of ratio includes sorting ratio in order according to the question. In this case, squash is mentioned first, then water. Hence, the ratio is:

squash:water = 1:6

Use cross multiplication:

1       :       6

100  :        ?

Multiply 100 by 6 then divide it by 1: which basically means 100 * 6 = 600 ml.

If you are unfamiliar with cross multiplication, then simply find out how many times did you have to multiply the 1 in the squash ratio to result to 100, which is 100, then multiply 6 by that answer = 6 * 100.

The equation that represents circles that have a diameter of 12 units and a center that lies on the y-axis is x²+ (y-3)² = 36. Therefore, option A is the correct answer.

The equation of circle provides an algebraic way to describe a circle, given the center and the length of the radius of a circle. The equation of a circle is different from the formulas that are used to calculate the area or the circumference of a circle.

The standard equation of a circle with center at (x₁, y₁) and radius r is (x-x₁)²+(y-y₁)²=r²

The standard form for finding the equation of a circle is expressed as;

(x-a)²+ (y-b)² =r²

Where; (a, b) is the center of the circle and r is the radius of the circle

Given that, diameter = 12 units

So, radius = 12/2 = 6 units

If the center lies on the y-axis, the center will be at (0, 3)

Substituting into the formula, we will have (x-0)² + (y-3)² = 6² equivalent to x²+ (y-3)² = 36

Therefore, option A is the correct answer.

The tangent of the subtraction of angles x and y is defined as follows:

tan(x - y) = (36 - 20π)/(48 + 15π)

The tangent of the subtraction of two angles is obtained according to the identity presented as follows:

tan(x - y) = [tan(x) - tan(y)]/[1 + tan(x)tan(y)]

The tangent of angle x is given as follows:

3/4.

The tangent and cotangent are defined as follows:

Hence the tangent of angle y is obtained inverting the numerator and the denominator of the function, as follows:

tan(y) = 5π/12.

The subtraction of the two tangents is given as follows:

tan(x) - tan(y) = 3/4 - 5π/12 = 9/12 - 5π/12 = (9 - 5π)/12.

The quotient of the two tangents is given as follows:

tan(x)tan(y) = 3/4 x 5π/12 = 15π/48.

Then the denominator of the expression is given as follows:

1 + 15π/48 = (48 + 15π)/48.

Considering the division of the two fractions, the tangent of the subtraction is defined as follows:

tan(x - y) = (9 - 5π)/12 x 48/(48 + 15π)

What is algebraic operation?

A basic algebraic operation in mathematics is any of the common arithmetic operations, such as addition, subtraction, multiplication, division, raising to a whole number power, and taking roots (fractional power).

Multiplication and division tasks should be completed first from left to right, followed by addition and subtraction tasks from left to right.

Given:

The equation 3x - y = - 1; - 3x - y = 5 when solved using the elimination method is x = -1 and y = -2 respectively.

3x - y = - 1

- 3x - y = 5

Subtract the equation to eliminate y

3x - (-3x) = - 1 - 5

3x + 3x = - 6

6x = - 6

divide both sides by 6

x = -6 / 6

x = -1

Substitute x = -1 into

Step-by-step explanation:

Approximately 68% of the data points in a dataset are expected to be within one standard deviation of the mean, assuming that the data follows a normal distribution. This is known as the Empirical Rule or the 68-95-99.7 rule. According to this rule, approximately 95% of the data points are expected to be within two standard deviations of the mean, and approximately 99.7% of the data points are expected to be within three standard deviations of the mean.

Please note that this rule applies only to a normal distribution, if the data is not normally distributed, the proportion may be different.

We can use the tangent function to solve for the height of the tower. The tangent of an angle is the ratio of the opposite side to the adjacent side in a right triangle.

First, we'll find the opposite side (the height of the tower) using the angle of elevation:

tan(21°) = opposite / 300

opposite = 300 * tan(21°)

Then we'll find the opposite side (the depth of the base of the tower below the window) using the angle of depression:

tan(20°) = opposite / 300

opposite = 300 * tan(20°)

Now we can add the two opposite sides we found to get the total height of the tower

height = opposite(elevation) + opposite(depression)

height = 300 * tan(21°) + 300 * tan(20°)

The angle should be converted to radians before using the tangent function, and the final answer should be rounded to 2 decimal places.

The circumference of a tire can be found by using the formula C = πd, where C is the circumference, and d is the diameter.

For the old bicycle with 12 inch diameter tires, the circumference is:

C = π * 12 = 12 * π inches

For the new bicycle with 16 inch diameter tires, the circumference is:

C = π * 16 = 16 * π inches

To find the difference in the circumference of the tires, we subtract the circumference of the old tire from the circumference of the new tire:

16π - 12π = 4π inches

So the difference in the circumference of the two tires is 4π inches.

It's around 12.56 inches.

Answer: Elijah's debt-to-credit ratio is 37%.

Step-by-step explanation:

Elijah's debt-to-credit ratio is the ratio of the amount of money he owes to the total amount of credit he has available.

To calculate the debt-to-credit ratio, we need to divide the amount of debt by the total amount of credit, and then multiply by 100 to get the answer in percentage.

Debt = $2,127.50

Credit = $5,750.00

Debt-to-credit ratio = (Debt / Credit) * 100

Debt-to-credit ratio = (2127.50 / 5750) * 100 = 37.29 ~ 37%

So the answer is: b) 37%

Since Z and 92 both have vertical angles, they are equal. Subtract from 180 to determine the measure of the other angle, which is 88 degrees since it forms a straight line with the 92-degree angle. Solve the expression by setting the value at 88.

∠AOB + ∠BOC = 180°

92°+( 10x  +  32 )° = 180°

10x + 32° = 180 - 92

10x + 32° = 88

10x = 88 - 32
