Ashley got $10 discount, at 40% discount on the meal worth $25.
What is percentage?Percentage is a part of the whole number. It is denoted by % sign.
1 %= 1/100.
Given that,
The cost of meal = $25.00
The discount given to Ashley on meal = 40%
The total value of discount = 25 x 40/100
= 1000/100
= 10
The total discount given by shopkeeper is $10.

A sample was taken of the metabolic rates of men participating in a study regarding diets. If each score is multiplied by 25 points , then the standard deviation of the new scores would:_______
Answer:
multiply by 25 also.
Step-by-step explanation:
If the scores are multiplied by 25, that means that the mean will also multiply by 25. Since the mean and the scores all increased by 25 times, the standard deviation will increase by 25 times.
If instead, you added 25 (or any other number) to each score, then the standard deviation would not change. The mean and each score will increase by 25, bu the difference between them will not change.

Rewrite p(x) as a product of linear factors.
p(2) =
Answer:
Rewriting p(x) as a product of linear factors: [tex]\mathbf{f(x)=(x+3)(x-2)(x+6)}[/tex]
Step-by-step explanation:
The polynomial [tex]p(x) = x^3 + 7x^2 - 36[/tex] has a known factor of [tex](x + 3)[/tex]
We need to find other factors.
First we find quotient of [tex]p(x) = x^3 + 7x^2 - 36[/tex] divided by [tex](x + 3)[/tex]
The division is shown in image attached.
The quotient is: [tex]x^2+4x-12[/tex]
Now, factoring the quotient [tex]x^2+4x-12[/tex]
[tex]x^2+4x-12\\=x^2+6x-2x-12\\=x(x+6)-2(x+6)\\=(x-2)(x+6)[/tex]
The other two factors are (x-2)(x+6)
So, Rewriting p(x) as a product of linear factors: [tex]f(x)=(x+3)(x-2)(x+6)[/tex]

Answer:
x = -3
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
-2x + 14 = 20
Step 2: Solve for x
Subtract 14 on both sides: -2x = 6Divide -2 on both sides: x = -3Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -2(-3) + 14 = 20Multiply: 6 + 14 = 20Add: 20 = 20Here we see that 20 does indeed equal 20.
∴ x = -3 is a solution of the equation.

A store pays $1.50 for a bag of candy. If the store wants to mark-up the price 60%,
for how much will the store sell the bag of candy?
Answer:
Selling price = $2.4
Step-by-step explanation:
Given:
Purchase price = $1.50
Increase in price = 60%
Find:
Selling price
Computation:
Selling price = Purchase price + (Purchase price)(Increase in price)
Selling price = $1.5 + (1.5)(60%)
Selling price = $1.5 + 0.9
Selling price = $2.4

Tomas is a commercial real estate agent who earns a yearly salary of $82,500 and a 2.5% commission on his total sales. If Tomas sold properties that totaled $3.75 million in sales during one year, what are Tomas’s earnings for that year?
Answer:
$176,250
Step-by-step explanation:
Multiply $3.75 million by Tomas commission on his total sales. Since you can't multiply a percentage you have to turn the commission into a decimal by moving it two spaces to the left. (Note: If it doesn't have a decimal add one at the end of the number then move it two spaces to the left)
$3,750,000 x .025 or 0.025 = $93,750
Add $93,750 to Tomas yearly salary
$93,750 + $82,500 = $176,250
So
If Tomas sold properties that totaled $3.75 million in sales during one year, his earnings for that year would be $176,250

A library contains only paperback and hardback books. If the ratio of paperback books to the total number of books is 3 to 5, which statement must be true? The ratio of paperback books to hardback books is 2 to 3. The ratio of paperback books to hardback books is 2 to 3. The ratio of paperback books to hardback books is 3 to 2. The ratio of paperback books to hardback books is 3 to 2. There are exactly 2 paperback books in the library. There are exactly 2 paperback books in the library. There are exactly 8 hardback books in the library. There are exactly 8 hardback books in the library.
Answer:
A library contains only paperback and hardback books. If the ratio of paperback books to the total number of books is 3 to 5, the true statement is:
The ratio of paperback books to hardback books is 3 to 2.
Step-by-step explanation:
The number of books in the library = 5
The number of paperback books in the library = 3
Therefore, the number of hardback books in the library = 2 (5 - 3)
Then, the relationship between the paperback books and the hardback books in the library can be expressed as a ratio of 3:2. This still gives the sum of the ratios as 5, which is the total number of books in the library, including paperback and hardback books.

Answer: The area of the triangle is 25 units^2.
Step-by-step explanation: The formula to find the area of the triangle is (base * height)/2. In this case, the base is 10 units long (on the x axis, it's the overall horizontal length of the triangle) and the height is 5 units long (the height can be calculated by finding the y axis length from the highest point of the triangle to the lowest). So (10*5)/2 = 50/2 which equals 25. And keep in mind, because this is the area, the unit will be units squared.

Anthony has been saving nickels (N), dimes (D), and quarters (Q) over the last year. He knows that he has twice as many nickels as quarters. When he takes the coins to the change machine to exchange them for paper money, he learns that he has 260 coins that total $29.75. Determine the number of each type of coin Anthony saved.
Answer:
75 number of quarters
150 number of nickels
35 number of dimes
Step-by-step explanation:
Let x, y and z be the amount of quarters, nickel and dimes respectively.
he learns that he has 260 coins, thus;
x + y + z = 260 - - - (1)
Now, we are told that he has twice as many nickels as quarters.
Thus, number of nickels = 2x
y = 2x - - - (2)
From online research, we have the following cost;
1 quarter = $0.25
1 nickel = $0.05
1 dime = $0.1
Total cost is $29.75. Therefore;
0.25x + 0.05y + 0.1z = 29.75 - - - (3)
Put 2x for y in eq (1) and eq (3) to get;
x + 2x + z = 260
3x + z = 260 - - - (eq 4)
0.25x + 0.05(2x) + 0.1z = 29.75
0.25x + 0.10x + 0.1z = 29.75
0.35x + 0.1z = 29.75 - - - (eq 5)
From eq(4), z = 260 - 3x
Thus;
0.35x + 0.1(260 - 3x) = 29.75
0.35x + 26 - 0.3x = 29.75
0.05x = 29.75 - 26
0.05x = 3.75
x = 3.75/0.05
x = 75
So, z = 260 - 3(75)
z = 260 - 225
z = 35
Since y = 2x,
Then,y = 2(75) = 150
Thus,we have;
75 number of quarters
150 number of nickels
35 number of dimes
