When markups are based on the selling price, the selling price is
A. cost – markup.
B. the portion.
C. 100% + cost percent.
D. 100%.
Answers
Markup is the amount added to the total cost of product to cover the total overheads and profit.
In markup based on selling price method, the selling price is considered as the endpoint that companies wanted to achieve, (100%) and the markup will be adjusted to cater into thaat equation.
When markups are based on the selling price, the selling price is seen as 100% since markup is a percentage of the selling price. The cost and markup together make up 100% of the selling price.
Explanation:When markups are based on the selling price, the selling price can be seen as 100%.
This is because the markup is calculated as a percentage of the selling price rather than the cost of the item.
Assuming that the entire selling price is 100%, the markup portion and the cost portion together make up this 100%.
The cost and markup are represented as percentages of the selling price, so if you know the cost and markup percentages, you can calculate the selling price.

The sum of a number and 12 is 20. What is the number?
Answers
The number is 8.
We verify:
x + 12 = 20
x = 20 - 12
x = 8
Regards !
I hope it helps you :)
"The sum of a number and 12..." The word sum is the keyword of what operation we are doing. We are doing addition. When we continue the phrase we know we are adding a number (an unknown) and 12.
So, on the left-hand side we have x + 12.
"... is 20" In mathematics, the word 'is' can mean equal. So, the left-hand side will equal the number 20.
Now we have the equation x + 12 = 20.
Solve for x.
x + 12 = 20
x = 8 <-- Subtract each side by 12
So, x is equal to 8.

A bouncing ball reaches a height of 27 feet at its first peak, 18 feet at its second peak, and 12 feet at its third peak. Describe how a sequence can be used to determine the height of the ball when it reaches its fourth peak.
Answers
so, let's take a peek, 27, 18, 12
now, to get the common factor from a geometric sequence, since it's just a multiplier, if you divide any of the terms by the term before it, the quotient is then the common factor, let's do so with hmm say 12 and 18, 12/18 = 2/3 <---- the common factor, you can check if you so wish with 18/27.
and the first term is of course, 27.
[tex]\bf n^{th}\textit{ term of a geometric sequence}\\\\ a_n=a_1\cdot r^{n-1}\qquad \begin{cases} n=n^{th}\ term\\ a_1=\textit{first term's value}\\ r=\textit{common ratio}\\ ----------\\ a_1=27\\ r=\frac{2}{3} \end{cases}\implies a_n=27\left( \frac{2}{3} \right)^{n-1}[/tex]
To determine the height of the bouncing ball at the fourth peak, we recognize a geometric sequence, where each peak's height is two-thirds of the previous peak. Applying this pattern, the height of the fourth peak is found to be 8 feet.
A sequence can be used to determine the height of a bouncing ball when it reaches its fourth peak. You can observe that the heights of the ball at each peak form a sequence, which in this case appears to be decreasing. By analyzing the pattern in the sequence, you can predict the height of the ball at its fourth peak.
A bouncing ball reaches various heights at different peaks which suggests a pattern. To determine the height of the fourth peak, we look at the sequence formed by the heights of the previous peaks. Noticing the pattern, each peak's height is [tex]\frac{2}{3}[/tex] of the previous one.
First peak: 27 feet
Second peak: 18 feet( [tex]27*\frac{2}{3}[/tex])
Third peak: 12 feet ([tex]18*\frac{2}{3}[/tex] )
To find the fourth peak, we continue the pattern:
Fourth peak: 12 feet *[tex]\frac{2}{3}[/tex] = 8 feet
Therefore, the fourth peak would be 8 feet high. By understanding the geometric sequence, we're able to predict future behavior.
You purchased 8 pounds 10 ounces of candy from a candy shop. You want to split it equally among 3 classrooms at a local school.
Answers
3 classrooms = 138 ounces
1 classroom = 138/3
= 46 ounces
= 2 pounds 14 ounces
Each classroom should receive 2 pounds and 14 ounces of candy.
Answer:
Each classroom will receive 2 pounds and 14 ounces of candy .
Step-by-step explanation:
Given that
Purchased candy= 8 pounds and 10 ounces
First we convert pound into ounces
1 Pound=16 ounces
8 pound = [tex]16\times 8[/tex]
8 pounds= 128 ounces
Now, purchased candy in ounces= 128+10=138 ounces
If we want to distribute purchased candy into three calssroom equally
Therefore, we divide purchased candy by 3
Each classroom receive candy= [tex]\frac{138}{3}[/tex]
Each classroom receive candy=46 ounces
Each classroom receive candy in pounds
16 ounces=1 pound
1 ounces=[tex]\frac{1}{16}[/tex] pounds
46 ounces=2 pounds and 14 ounces
Each classroom receive candy=2 pounds and 14 ounces
Hence, each classroom receive candy =2 pounds and 14 ounces.Juanita is making necklaces to give as presents. She plans to put 15 beads on each necklace. Beads are sold in packages of 20. What is the least number of packages she can buy to make necklaces and have no beads left over

Find the average rate of change of f on the interval [50, 70].
Answers
Final answer:
The average rate of change of a function on an interval is calculated by finding the difference in the function's values at the endpoints of the interval, and then dividing that difference by the length of the interval. In this case, the interval is [50, 70], so the average rate of change of the function is (f(70) - f(50)) / (70 - 50).
Explanation:
The average rate of change of a function on an interval is calculated by finding the difference in the function's values at the endpoints of the interval, and then dividing that difference by the length of the interval.
In this case, the interval is [50, 70], so the average rate of change of the function is (f(70) - f(50)) / (70 - 50).
For example, if the function is f(x) = 2x + 3, then the average rate of change on the interval [50, 70] would be (f(70) - f(50)) / (70 - 50) = (2(70) + 3) - (2(50) + 3) / 20 = (143 - 103) / 20 = 40 / 20 = 2.

What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given,
Fabric required in 1 larger window = 3 3/4
⇒ [(4×3)+3] /4 = 15/4
Fabric required in 1 smaller window = 1 1/3
⇒ (3+1)/3 = 4/3
Now,
Mary has 2 larger windows and 3 smaller
So,
Total fabric = 2 Larger + 3 smaller
Total fabric = 2(15/4) + 3(4/3)
Total fabric = 15/2 + 4
Total fabric = 23/2
Hence "Marys need a total of 23/2 yard of fabric for his all windows".

the length of a each edge of a cube is x centimeters. if x is an integer, why can't the volume of the cube equal 15cm3
Answers
The volume of the cube can't equal 15cm ³ because 15 has no cube roots, the volume of the cube equals 15 cm squared.
What is the volume of the cube?The volume of a cube is equal to the product of the length, width, and height of a cube.
The volume of a cube is given by the formula as
The volume of a cube = length × breadth× height
What is a cube root?The cube root of a number is the component that we multiply by itself three times to produce that number.
The cube root is denoted by the'∛ ' symbol.
Example: ∛216 = ∛(6 × 6 × 6) = 6.
Here the length of each edge of a cube is x centimeters.
If we write the cube of a number

Suppose that you have 8 cards. 5 are green and 3 are yellow. the 5 green cards are numbered 1, 2, 3, 4, and 5. the 3 yellow cards are numbered 1, 2, and 3. the cards are well shuffled. suppose that you randomly draw two cards, one at a time, and with replacement. ⢠g1 = first card is green ⢠g2 = second card is green enter the probability as a fraction. p(g1 and g2)
Answers
The probability of drawing a green card on both the first and second draw, with replacement, is 25/64, as each draw is an independent event with the same probability of 5/8 for drawing a green card.
Explanation:The problem is asking us to compute the probability of drawing two green cards in succession, with replacement, from a deck that contains eight cards of which five are green and three are yellow. Since the draws are independent and with replacement, the probability of an event occurring on the first draw is not affected by the second draw, and vice versa.
To calculate the probability of drawing a green card on the first draw, denoted as P(G₁), we look at the number of green cards and the total number of cards. There are 5 green cards out of 8 total cards, so P(G₁) = 5/8.
Because we are replacing the drawn card before the second draw, the probability of drawing a green card on the second draw, denoted as P(G₂), remains the same as for the first draw, thus P(G₂) = 5/8.
The probability of both events happening, denoted as P(G₁ and G₂), is the product of the individual probabilities since the draws are independent. Therefore, we have:
P(G₁ and G₂) = P(G₁) * P(G₂) = (5/8) * (5/8) = 25/64.
