You bought some jeans for $55. Today they were on sale for $49.50. What was the percent decrease in price?

10% decrease

Explain how you these answers are right

Answers

Answer:

Step-by-step explanation:

Profit % = \(\frac{New Value - Old Value}{Old value}\)x 100

Loss % = \(\frac{Old Value-NewValue}{Old Value}\)

Profit % = \(\frac{16.1-5}{5}\) × 100

= \(\frac{11.1}{5}\) x 100

= 11.1 x 20

= 222% increase

∴ Hence, proved that the answer is correct.

Profit % = \(\frac{57.6-40}{40}\)×100

= 44% increase

∴ Hence, proved that the answer is correct.

Profit % = \(\frac{63.6-60}{60}\)x 100

= 6% increase

∴ Hence, proved that the answer is correct.

Loss % = \(\frac{110-13.2}{110}\)x 100

= 88% decrease

∴ Hence, proved that the answer is correct.

Loss % = \(\frac{55-49.5}{55}\)x 100

= 10% decrease

∴ Hence, proved that the answer is correct.

Answer:

Step-by-step explanation:

Old Value:  5

            New Value:   16.1

16.1-5=11.1

11.1 divided by 5= 2.22

2.22/1 x 100=222%

222% increase

Old Value:  40

            New Value:  57.6

57.6-40=17.6

17.6 divided by 40= 0.44

0.44/1 x 100= 44%

44% increase

Old Value:  60

           New Value:   63.6

63.6-60=3.6

3.6 divided by 60= 0.06

0.06/1 x 100= 6%

6% increase

Old Value:  110

           New Value:   13.2

13.2-110= -96.8

-96.8 divided by 110= -0.88

-0.88/1 x 100= 88%

1. Do the product rule:
Since the base of both numbers are the same, keep the base. In this case, it’s 2. Next add the exponents together. 3 + 2 = 5.
So the simplified one would be 2^5 (two to the fifth power)

2. Multiply 2 by itself five times; 2 • 2 • 2 • 2 • 2 = 64
So evaluated (calculated) the answer would be 64.

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.

Answers

The function for the points are  y = -15x - 5

How to determine the function

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

m is the slope of the liney - y₁ and (x - x₁) are the points

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

5; for each additional hour a student studies, their grade is predicted to increase by 5% on the test

Answers

Answer:

Step-by-step explanation:

The y-intercept of the line of fit is 70, which means that a student who does not study at all (0 hours) is predicted to earn a grade of 70%. In other words, the line of fit starts at the point (0,70), indicating that even if a student does not study at all, they can still earn a grade of 70% on the test. However, it should be noted that this prediction may not always hold true for all students and situations. The y-intercept provides a useful reference point for interpreting the rest of the data, and helps to establish a baseline for the relationship between study time and test grades.

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?

Answers

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

Answers

Answer:

  113 cm²

Step-by-step explanation:

You want the area of the given composite shape.

Composition

The shape is already divided for you into a lower part that is a trapezoid and an upper part that is a parallelogram.

Trapezoid

The area of the trapezoid is given by ...

  A = 1/2(b1 +b2)h

  A = 1/2(14 +7)(6) = 63 . . . . square centimeters

Parallelogram

The area of the parallelogram is given by ...

  A = bh

  A = (10)(5) = 50 . . . . square centimeters

Figure area

The area of the figure is the sum of the areas of its parts:

  figure area = trapezoid area + parallelogram area

  figure area = 63 cm² +50 cm² = 113 cm²

The area of the figure is 113 square centimeters.

Simplify -15- |-7.5|

Answers

Answer:

-22.5

Step-by-step explanation:

-15- |-7.5|

after taking the absolute value off, -7.5 would become positive 7.5. But then the negative outside the absolute value makes it negative again.

-15-7.5

=-22.5

The simplified expression -15 - |-7.5| is equal to -22.5.

To simplify the expression -15 - |-7.5|, we'll follow these steps:

Evaluate the absolute value: |-7.5|.

The absolute value of a number is its distance from zero on the number line. In this case, |-7.5| is equal to 7.5 because 7.5 units away from zero.

Substitute the absolute value into the expression:

-15 - 7.5.

Perform the subtraction:

-15 - 7.5 = -22.5.

Therefore, the simplified expression -15 - |-7.5| is equal to -22.5.

(a). The shape will be decomposed into two (2) trapezoid

(b). For the bigger trapezoid;

area of smaller trapezoid = 1/2 × (2.5 + 6) × 2 ft²

area of smaller trapezoid = 8.5 ft²

Total square feet area of carpet = 20.5 ft² + 8.5 ft²

how to check : 3x+5=11

Answers

Answer:

There are two ways to check if 3x+5=11 is true:

Subtract 5 from both sides of the equation. This will isolate x on the left-hand side of the equation.

3x = 6

Divide both sides of the equation by 3. This will divide both sides of the equation by 3, which will cancel out the 3 on the left-hand side of the equation, leaving x by itself.

x = 2

You can also check if 3x+5=11 is true by plugging in 2 for x. If you do this, you will get 3(2)+5 = 6+5 = 11. Therefore, 3x+5=11 is true when x=2.

Subtract 5 from both sides
