Answer:
no
Step-by-step explanation:
thirty percent of $28 is $8.4, so you would subtract the two leaving you with $19.6
2.5 sales tax of $19.6 is $0.49
Adding those two, the total comes to 20.09 which is just over budget
The amount of the book is more than $20. Then she does not have enough money.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Let 'x' be the markdown price. Then the equation is given as,
30% = [(28 - x) / 28] × 100
0.30 = [(28 - x) / 28]
8.4 = 28 - x
x = $19.6
Then the amount of book after tax is given as,
⇒ $19.6 x 1.025
⇒ $20.09
The amount of the book is more than $20. Then she does not have enough money.

Rafeal wants to know if there is a single transformation that will move trapezoid JKLM onto trapezoid PQRS Below
Which Statement is true?
A. A 90 counterclockwise roation of trapezoid JKLM about the origin will move angle L onto angle R
B. A 180 rotation of trapezoid JKLM about the origin will move angle J onto angle R
C. A reflection of trapezoid JKLM across the y-axis will move angle K onto angle R
D. There is no transformation Rafael can use because trapezoids JKLM and PQRS are not congruent
A. A 90° counterclockwise rotation of trapezoid JKLM about the origin will move angle L onto angle R.
Step-by-step explanation:
Since both the trapezoids, trapezoid JKLM and PQRS are congruent, we can do any transformation, may be rotation, reflection and translation.
A 90° counterclockwise rotation of trapezoid JKLM about the origin will move angle L onto angle R is the true statement others are incorrect statements.
When the Preimage is rotated 90° counterclockwise rotation, then its coordinates (x,y) changed into (-y,x)
Kelly has a rock garden with a length of 6 feet. She constructs a scale model of the rock garden using
the scale 1 inch:2 feet.
What is the length of the garden in her model? Show your work, including your proportion.
If the width is 5 inches for the scale model and the scale is still 1 inch to 2 feet, will her scale
model drawing fit on a piece of paper that is 8.5 inches by 7 inches? Why or why not?
Answer:
Answer:
3 inches
It will fit in the paper.
Step-by-step explanation:
In the scale drawing the 2 feet original length is converted to 1 inch drawing length as Kelly constructs a scale model of the rock garden using the scale 1 inch : 2 feet.
Now the proportion is 1 inch : (2 × 12) inches = 1 : 24 {Since 1 foot is equivalent to 12 inches}
Now, maintaining that scale ratio the 6 feet original length of the garden will be converted to [tex]\frac{1}{24} \times (6 \times 12) = 3[/tex] inches in the drawing.
It is also given that the width of the garden in the scale model is 5 inches and the scale is still 1 inch : 2 feet.
Therefore, the dimensions of the garden in the model is 3 inches by 5 inches and this will fit on a piece of paper that is 8.5 inches by 7 inches. (Answer)

On a certain hot summer's day, 391 people used the public swimming pool. The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $752.75. How many children and how many adults swam at the public pool that day?
Final answer:
there were 127 children and 264 adults.
Explanation:
To solve this problem, we use a system of equations. Let's denote the number of children as C and the number of adults as A. We know two facts: the total number of people is 391, and the total amount of money collected is $752.75. Therefore, we have the equations:
C + A = 3911.25C + 2.25A = 752.75To solve this system, we first multiply the first equation by 1.25 to align the coefficient of C with the second equation:
1.25(C + A) = 1.25(391)1.25C + 1.25A = 488.75Next, we subtract this result from the second equation to eliminate C, leaving an equation in terms of A only:
2.25A - 1.25A = 752.75 - 488.75
A = (264) / 1 = 264
Substituting the value of A into the first equation, we find the value of C:
C + 264 = 391
C = 127
Therefore, there were 127 children and 264 adults who swam at the public pool that day.
Prime factor of 2080
Answer:
2 x 2 x 2 x 2 x 2 x 5 x 13
Step-by-step explanation:
The Prime Factorization is:
2 x 2 x 2 x 2 x 2 x 5 x 13
In Exponential Form:
25 x 51 x 131
CSV Format:
2, 2, 2, 2, 2, 5, 13
The prime factors of 2080 are 2, 2, 2, 2, 5, and 13.
Divide 2080 by the smallest prime number, which is 2:
2080 ÷ 2 = 1040
Continue dividing by 2:
1040 ÷ 2 = 520
Continue dividing by 2:
520 ÷ 2 = 260
Continue dividing by 2:
260 ÷ 2 = 130
Continue dividing by 2:
130 ÷ 2 = 65
Now, 65 is not divisible by 2.
Move to the next prime number, which is 5:
65 ÷ 5 = 13
13 is a prime number.
So, the prime factors of 2080 are 2, 2, 2, 2, 5, and 13. In exponential form, this can be written as 24 * 5 *13.

Roxy has some necklaces. Kelly has 4 times more rings than Roxy. Together they have 35. How many necklaces does Roxy have?
Answer:
Roxy has 7 necklaces.
Step-by-step explanation:
35 = n + 4n
35 = 5n
5 = 5
n = 7
The problem is a simple algebra problem related to ratios. By setting up an equation according to the given information, we find that Roxy has 7 necklaces.
Explanation:This is a math problem concerning ratios and simple algebra. Let's denote the number of necklaces that Roxy has as R. Then, Kelly has 4 times more rings, which is 4R. Together they have 35. So, the equation can be set up as:
R + 4R = 35
Combine like terms, you get:
5R = 35
Then, you can solve for R by dividing both sides by 5:
R = 35/5 = 7
So, Roxy has 7 necklaces.

The value of y varies directly as the square of x and y=36 when x=3. What is y when x=4?
Answer: y = 64
Step-by-step explanation:
y <> x² ----------------------- 1
y = kx² ----------------------- 2
36 = 3²k
36 = 9k
K = 36/9
= 4.
To find y when x = 4, we substitute for x in equation 2
y = kx²
y = 4²k
y = 16 x 4
y = 64
The value of y, which varies directly as the square of x, is determined by first identifying the constant of variation from the given values, in this case, y = 36 when x = 3. The constant is found to be 4. Using this constant (k), when x is 4, y will be 64.
Explanation:The value of y varies directly as the square of x, which is represented mathematically as y = kx², where k is the constant of variation. Using the given that y = 36 when x = 3, we can determine k by substituting these values into the equation. Thus, k = y/x² = 36/9 = 4. Now, having the value for k, we can find y when x = 4 by substituting these values into the equation: y = kx² = 4×16 = 64. Therefore, y equals 64 when x equals 4 in the given relation.

in Eduardo’s collection, the number of butterflies is 12 more than twice the number of moths. If there are x moths, write an expression to represent the number of butterflies he has.
Answer:
An expression to represent the number of butterflies he has is y = 12 + 2x
Step-by-step explanation:
Let the number of butterflies in Eduardo’s collection be y
Then according to the question
The number of moths = x
The number of butterflies y = 12 + twice the number of moths---------(1)
Twice the number of moths = [tex]2 \times \text{number of moths}[/tex]

The x intercept is [tex](\frac{-2}{5}, 0)[/tex]
The y intercept is [tex](0, \frac{-2}{3})[/tex]
Solution:
Given equation is:
10x + 6y = -4
The x intercept is the point where the line crosses the x axis
The y intercept is the point where the line crosses the y axis
Find x intercept:
Substitute y = 0 in given equation
10x + 6(0) = -4
10x = -4
[tex]x = \frac{-4}{10}\\\\x = \frac{-2}{5}[/tex]
Thus the x intercept is [tex](\frac{-2}{5}, 0)[/tex]
Find y intercept:
Substitute x = 0 in given equation
10(0) + 6y = -4
[tex]6y = -4\\\\y = \frac{-4}{6}\\\\y = \frac{-2}{3}[/tex]
Thus the y intercept is [tex](0, \frac{-2}{3})[/tex]
Area of a rectangle is 100 sq ft. The length is 10 ft longer than twice it’s width. What is the length and the width.
The length of the rectange is 20ft and width of the 5ft.
Step-by-step explanation:
Let us consider a rectangle and its area is known to be 100 sq ft.
We are given the information that the length of the rectangle is 10ft longer than twice its width.
⇒Length l = 2w+10.
Where w is the width of the rectangle.
The formula for area of the rectangle A = length × width.
A= (2w+10)×w.
100 = [tex]2w^2+10w[/tex].
0=[tex]2w^2+10w-100[/tex].
Thus it forms an quadratic equation we have to solve for the solution.
0=(2w-10)(w+10).
2w-10=0. w+10=0.
2w=10. w=-10. (negative value cannot be choosed.)
w=[tex](\frac{10}{2} )[/tex].
w=5ft.
Thus width is is 5 ft.
Length = 2(5)+10.
=10+10.
=20ft.
Thus the length is 20ft.

Answer:
1. Yes
2. Yes
Step-by-step explanation:
Leah wrote 2 different fractions with the same denominator. Both fractions were less than 1.
1. Can their sum equal 1?
Let Leah fractions be [tex]\dfrac{6}{7}[/tex] and [tex]\dfrac{1}{7}.[/tex] Both these fractions have the same denominators and are less than 1. Find their sum:
[tex]\dfrac{6}{7}+\dfrac{1}{7}=\dfrac{7}{7}=1[/tex]
2. Can their sum be greater than 1?
Let Leah fractions be [tex]\dfrac{6}{7}[/tex] and [tex]\dfrac{5}{7}[/tex]. Both these fractions have the same denominators and are less than 1. Find their sum:
[tex]\dfrac{6}{7}+\dfrac{5}{7}=\dfrac{11}{7}=1\dfrac{4}{7}>1[/tex]
Two fractions with the same denominator can sum to 1 if their numerators add up to the denominator, or they can sum to more than 1 if their numerators together exceed the denominator. This is based on the concept of adding fractions where only the numerators are summed.
Leah wrote two different fractions with the same denominator, and both were less than 1. Can their sum equal 1? Can their sum be greater than 1? The answer to both questions depends on the value of the numerators. Fractions represent parts of a whole. For two fractions with the same denominator to have a sum of 1, the numerators must add up to the denominator. If their sum is greater than the denominator, then the total sum would be greater than 1.
For example, if we have fractions ½ and ¾, their sum is ½ + ¾ = ¾ which is less than 1. However, if we have ¾ and ¾, the sum equals 6/4, which reduces to 1½, a sum greater than 1.
In conclusion, two fractions with the same denominator and each less than 1 can sum to 1 if the numerators total the denominator, or can sum to greater than 1 if the numerators together exceed the denominator. An important aspect of adding fractions is that we only add the numerators and never the denominators.

4.) Mr. Souders purchased a car priced at $9800. He paid $500 down and
agreed to a monthly payment of $250 per month for 48 months.
Including the down payment, what is the total cost of the car?
Please show your work.
Answer:
The total cost of the car including the down payment = $12,500
Step-by-step explanation:
The Original price of the car = $9800
The amount paid for down payment = $500
Also, the monthly payment amount = $250
Now, the number of months, the amount is paid = 48 months
So, the TOTAL amount paid in 48 months
= 48 x ( Amount paid each month) = 48 x ( $250)
= $12,000
So, the TOTAL PRICE of CAR paid = Total amount paid in 48 months + The amount paid for down payment
= $12,000 + $500
= $12,500
Hence, the total cost of the car including the down payment = $12,500
Ella and her children went into a bakery and where they sell cookies for $0.50 each and brownies for $2.25 each. Ella has $15 to spend and must buy a minimum of 9 cookies and brownies altogether. If Ella decided to buy 5 cookies, determine the maximum number of brownies that she could buy. If there are no possible solutions, submit an empty answer.
Answer: 5 brownies
Step-by-step explanation:
cookies = 5 x $0.50 = $2.5
$15 - $2.5 = $12.5
$12.5 divided by $2.25 = $5.555
so at the most ella can buy 5 brownies if she buys 5 cookies
Answer:
If each cookie is .50 and she wants to buy 5 cookies @ .50= $2.50
Than subtract $2,50 from $15.00 (which she has to spend you have $12.50
Then divide 2.25 into $12.5 and you get an answer of 5 brownies with a $1.30 extra to spend

Which of the following expressions are equivalent to -8 -(-1)-5
Answer:
Step-by-step explanation:
-8 -(-1)-5
Opening bracket
= -8 + 1 - 5
= -12
The student's expression -8 -(-1)-5 simplifies to -8 + 1 - 5, which is equal to -12 after performing the addition and subtraction sequentially.
The expression in question is -8 -(-1)-5. To solve this, we need to recognize that subtracting a negative number is the same as adding its positive equivalent. So, the expression simplifies to -8 + 1 - 5.
Now, we perform the addition and subtraction in the order they appear:
First, we add 1 to -8, which gives us -7.Then, we subtract 5 from -7, which gives us -12.Therefore, the expression -8 -(-1)-5 is equivalent to -12.
