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
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%
88% decrease

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom 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 pointsUsing (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
\(a=-15b-5\)

Data was collected on the amount of time that a random sample of 8 students spent studying for a test and the grades they earned on the test. A scatter plot and line of fit were created for the data.
scatter plot titled students' data, with points plotted at 1 comma 80, 2 comma 70, 2 comma 80, 2 comma 90, 3 comma 80, 3 comma 100, 4 comma 90, and 4 comma 98, and a line of fit drawn passing through the points 0 comma 70 and 1 comma 75
Find the y-intercept of the line of fit and explain its meaning in the context of the data.
80; a student who studies for 0 hours is predicted to earn 80% on the test
70; a student who studies for 0 hours is predicted to earn 70% on the test
10; for each additional hour a student studies, their grade is predicted to increase by 10% on the test
5; for each additional hour a student studies, their grade is predicted to increase by 5% on the test
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?
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

Find the area of each figure. If necessary, use 3.14 for π and round to the nearest hundredth. (Example 1)
Answer:
113 cm²
Step-by-step explanation:
You want the area of the given composite shape.
CompositionThe shape is already divided for you into a lower part that is a trapezoid and an upper part that is a parallelogram.
TrapezoidThe area of the trapezoid is given by ...
A = 1/2(b1 +b2)h
A = 1/2(14 +7)(6) = 63 . . . . square centimeters
ParallelogramThe area of the parallelogram is given by ...
A = bh
A = (10)(5) = 50 . . . . square centimeters
Figure areaThe 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|
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;
8ft 6in = 8.5 ft
area of bigger trapezoid = 1/2 × (8.5 + 12) × 2 ft²
area of bigger trapezoid = 20.5 ft²
For the smaller trapezoid;
2ft 6in = 2.5 ft
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
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.
