The monthly payment would be an amount of $226.67.

A monthly payment is a payment made every month to pay off loans or advances. It's similar to EMI.

Mary takes out a loan for $6,000 at a simple interest rate of 12% to be paid back in 36 monthly installments.

The total payback = P× r/100 × T + P

Here P = $6,000 , r = 12, and T = 3 years

The total payback = 6,000 × 12/100 × 3 + 6,000

The total payback = 6,000 × 0.12 × 3 + 6,000

The total payback = $8,160

The total payback of the borrowings will be $8,160 over a three-year period. The monthly payment for this will be,

The monthly payment = Total payback / No. of payment

The monthly payment = 8,160/36

The monthly payment = $226.67

Therefore, the monthly payment would be an amount of $226.67.

Step-by-step explanation:when we add the 12+5 together and will be the answer

When two numbers added together result in 0, this is known as additive inverse. Using this notion, points on a number line are used to depict additive inverse.

The dotted points with the numbers 3 and -3 are the places on the number line.

To determine whether the points show an additive inverse:

Points 1 and 2 add up to 0.

3 + (-3) = (3 - 3) = 0

When two numbers added together result in 0, this is known as additive inverse.

Using this notion, points on a number line are used to depict additive inverse.

Thus, the points therefore display additive inverse.

Domain: (−∞,∞),{x|x∈R} and Range: (−∞,∞),{y|y∈R} for f(x)=0.5x

A relation is a function if it has only One y-value for each x-value.

Given,

Helene is selling cupcakes for $0.50 each.

The function f(x)=0.5x gives the total amount of money Helene makes after selling x cup cakes.

We need to find the domain and range of the function

solve the equation f(x)=0.5x to determine the values of the independent variable x and obtain the domain.

To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).

Domain: (−∞,∞),{x|x∈R}

Range: (−∞,∞),{y|y∈R}

Hence, Domain: (−∞,∞),{x|x∈R} and Range: (−∞,∞),{y|y∈R} for f(x)=0.5x

The mean absolute deviation of the given values would be = 4.3125

The mean absolute deviation in statistics is defined as the average distance between each data point and the mean and this gives us an idea about the variability in the dataset.

To calculate the mean absolute deviation the following is carried out:

76, 70, 66, 80, 72, 67, 78, 69 = 578/ 8 = 72.25

76-72.25 = 3.75

70-72.25 = 2.25

66-72.25 = 6.25

80-72.25 = 7.75

72-72.25 = 0.25

67-72.25 = 5.25

78-72.25 = 5.75

69-72.25 = 3.25

3.75+2.25+6.25+7.75+0.25+5.25+5.75+3.25 = 34.5

Step-by-step explanation:

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

9 pounds = $8.37

1 pound = $0.98

The amount saved per pound is $0.98

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

Krystal bought 9 pounds of ground beef. She saved $8.37 by using a coupon.

This means,

9 pounds = $8.37

Divide both sides by 9.

1 pounds = 8.37/9

Answer:3,4

Step-by-step explanation:

In point-slope form, the equation of the parallel line to y − 5 = 3/4(x − 2) is: y - 4 = 3/4(x + 1).

If two lines are parallel their equation, written in point-slope form y - b = m(x - a), will have the same value of m, which is the same slope.

The slope of the line with the equation y - 5 = 3/4(x - 2), is 3/4. This means that the line that passes through the point (−1, 4), and that is parallel to the line with the equation y − 5 = 3/4(x − 2), will have the same slope, m = 3/4.

To write the equation of the line that is parallel to y - 5 = 3/4(x - 2), in point-slope form, substitute m = 3/4 and (a, b) = (-1, 4) into y - b = m(x - a):

y - 4 = 3/4(x - (-1))

y - 4 = 3/4(x + 1)

The equation of the line that is parallel to y − 5 = 3/4(x − 2) is therefore expressed in point-slope form as: y - 4 = 3/4(x + 1).

Proportionately, since a 3/4 inch cork stopper is too small for sealing the bottle, the Sailor should next try a 4/5 inch cork stopper, and not a 1/2 inch cork stopper.

Proportion refers to the ratio or relative value between two values.

Proportions are fractional values.

And like ratios, proportions can be expressed as fractions, decimals, or percentages.

To determine the relative sizes of these cork stoppers, we can express them in percentages or decimals and other fractions.

3/4 equals 75%, 7.5/10, 75/100, or 0.75.

1/2 equals 50%, 5/10, 50/100, or 0.50.

4/5 equals 80%, 8/10, or 80/100, or 0.80

The Domain and Range are −2 ≤ x ≤ ∞ & 0 ≤ y ≤ ∞ respectively.

What are the Domain and Range?

Graphs can be used as another tool for determining the domain and range of functions. The domain of a graph is made up of all the input values displayed on the x-axis since the term "domain" refers to the set of potential input values. The y-axis on a graph represents the possible output values or range.

Domain:

The x-value at the farthest left point is at x = −2. Now continue tracing the graph until you get to the point that is the farthest to the right. The x-value at this point is at ∞. There are no breaks in the graph going from left to right which means it’s continuous from -2 to ∞.

Domain: [-2, ∞][−2, ∞] also written as −2 ≤ x ≤ ∞

Range:

Look at the furthest point down on the graph or the bottom of the graph. The y-value at this point is y=0. Now, look at how far up the graph goes or the top of the graph. This is when x = ∞, but now we’re finding the range so we need to look at the yy-value of this point which is at y = 0. There are no breaks in the graph going from down to up which means it’s continuous.

Range: [0, ∞][0, ∞] also written as 0 ≤ y ≤ ∞.

Hence, the Domain and Range are −2 ≤ x ≤ ∞ & 0 ≤ y ≤ ∞ respectively.
