Jeans are on sale for 25% off. The jeans Bailee wants to buy are marked with an original price of $60. What is the total cost, in dollars, for a pair of jeans at the sale price, including a 7% tax?

Answers

25% of 60 is 15$ so the sale price would be 45$
7% tax = 3.15
= $48.15

I hope this helps :)

The total cost for a pair of jeans at the sale price including 7% tax is $96.30.

What is Percentage?

Percentage, denoted by %, is defined as the parts of a number per fraction of 100.

We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

here, we have,

Given that,

Original price of the jeans = $60

Discount percentage = 25%

Amount of discount = 25% × 60

= 0.25 × 60

= $15

Price of a jean at the sales price = $60 - $15 = $45

Percentage tax = 7%

Tax amount = 7% × 45 = 0.07 × 45 = $3.15

Price of the jean after tax = $45 + $3.15 = $48.15

Total cost for a pair of jeans = 2 × $48.15 = $96.30

Hence the total cost is $96.30.

How do you solve for x and y?

Answers

Answer:

x = 60°, y = 30°

Step-by-step explanation:

The sum of the triangle angles is always 180°

Therefore 90° + x + y = 180°

It is also known that x = 2y

// combine the given value of x into the previous expression

90° + 2y + y = 180°

2y + y = 180° - 90°

3y = 90°

// divide both sides by 3

y = 30°

// then combine the given value of y into the expression x = 2y

x = 2 * 30°

x = 60°

Which of the following represents the independent variable of the function?

y=1/2x-2

A. 1/2

B. x

C. y

D. -2

Answers

Answer:

X is the independent variable

Step-by-step explanation:

I just know

X is the independent variable that represents the independent variable of the function.

What are independent and dependent variables?

Even though everything can be almost always related to its reason, when we talk about two related things, there might happen that one of those things is dependent on other.

If a variable is taking its values independently of any visible direct cause, then that variable is called independent variable.

We are given an expression as y=1/2x-2

Here we can see the variables x and y .

the y intercept is -2.

The slope of the equation is 1/2.

Therefore, we can conclude that the X is the independent variable.

Is it possible to form a triangle with side lengths 3.5 3.5, and 9? If so, will it be scalene, isosceles, or equilateral? Or none

Answers

Answer:

It is not possible to draw a triangle with given measurements of 3.5, 3.5, and 9.

Step-by-step explanation:

Scalene Triangle - All 3 sides have different lengths.

Isosceles Triangle - 2 sides have equal lengths.

Equilateral Triangle - All 3 sides have equal lengths.

You must be thinking that it would be Isosceles triangle, but it is not. The measurements you gave is 3.5, 3.5, and 9. Grab a piece of paper, ruler, and a pencil. First draw the length of 9 cm with your pencil and ruler (let us pretend that the measurements are in cm). Then draw 3.5 cm by placing your ruler on the end/start of your 9cm line that you drew before. Then, once again draw a 3.5 cm on the other end of the 9cm line. You will see something like the picture above. You can see that the two sides of the triangle are not intersecting on the top. This means that the triangle formation cannot be made by the given measurements of 3.5, 3.5, and 9.

I hope you understand my answer and this is an easy way to find if, from the given measurements, a triangle is able to be drawn. Thank you !!

The given side lengths, 3.5 3.5, and 9, cannot form a triangle.

The Triangle Inequality TheoremThe triangle inequality theorem states that for any triangle, the sum of any two of its side must be greater than the length of the third side.

Given the side lengths, 3.5 3.5, and 9:

3.5 + 3.5 (7) is not greater than 9

Thus, we can conclude that the given side lengths, 3.5 3.5, and 9, cannot form a triangle.

Answer:

y = 240,000(1.048)^t

Step-by-step explanation:

Initial population: p = 240,000

Annual growth rate: 4.8% = 0.048

Number of years: t

Population in year t: y

y = p(1 + r)^t

y = 240,000(1 + 0.048)^t

y = 240,000(1.048)^t

1. Find the maximum and minimum values of z = 2x + 3y subject to the following constraints

and y =
minimum value =
when x =
and y=

Answers

Answer:

Minimum Values:

x = 0, y = 1, z = 3

Maximum Values:

x = 7 , y = 11 , z = 47

Step-by-step explanation:

FOR MINIMUM VALUES:

0<= x <= 7

It is clear from the above inequality that the minimum value of x must be 0.

y>= 1

This inequality shows that the minimum value of y must be 1. Using these minimum values of x and y to get the minimum value of z:

z = 2x + 3y

z = (2)(0) + (3)(1)

z = 3 (Minimum)

FOR MAXIMUM VALUES:

0<= x <= 7

It is clear from the above inequality that the maximum value of x must be 7.

x + y <= 11

To calculate maximum value of y we can use the minimum value of x in this inequality:

0 + y <= 11

y <= 11

Hence, the maximum value of y is 11.

Using these maximum values of x and y to get the maximum value of z:

z = 2x + 3y

z = (2)(7) + (3)(11)

z = 47 (Maximum)

Are x and y proportional?
