Answer:
A,B,D
Step-by-step explanation:
case A) If the price is marked down by percent, the new price will be
we know that
If the price is marked down by 10 percent
then the new price will be
10%= 10/100=0.10
(1 - 0.10) *$28= 0.90 * $28
=$25.20
therefore The statement case A) is True
case B) If the price is marked down by 25 percent, the new price will be $21
we know that
If the price is marked down by 25 percent
then the new price will be
25%=25/100=0.25
(1-0.25)* $28=0.75*$28
=$21
therefore The statement case B) is True
case C) If the price is marked down by 50 percent, the new price will be $19 we know that
If the price is marked down by 50 percent
then the new price will be
50%=50/100=0.50
(1-0.50)*$28= 0.50*$28
=14
therefore The statement case C) is False
case D) If the price is marked down by 35 percent, the new price will be $18.20
we know that
If the price is marked down by 35 percent
then the new price will be
35%= 35/100=0.35
(1-0.35)* $28=0.65*$28
=18.20
therefore The statement case D) is True
case E) If the price is marked down by 40 percent, the new price will be $29.80 we know that
If the price is marked down by 40 percent
then the new price will be
40%=40/100=0.40
(1-0.40)*$28= 0.60*$28
=$16.80
therefore The statement case E) is False

Step-by-step explanation:
First, at up an equation based on the problem:
2 - ⅓x = 4 + 6
Then, solve for x:
2 - ⅓x = 10
-⅓x = 8
x = -24
OR
2 = 10 + ⅓x
-8 = ⅓x
-24 = x

At a grocery store, 7 apples and 2 oranges will cost $12.80. In addition, 6 apples and 3
oranges cost $12.00. Assuming that we are talking about the same apples and oranges, what is the
cost of 1 apple? What is the cost of 1 orange? Let x represent the cost of an apple
and y represent the cost of an orange. Show ALL work!
Equation #1:
Equation #2:
Cost of 1 apple: $
Cost of 1 orange: $
Answers
Answer:
Equation 1: 7x + 2y = 12.8
Equation 2: 6x + 3y = 12
Cost of 1 apple: $1.60
Cost of 1 orange: $0.80
Cost of 1 orange: $Step-by-step explanation:
Let's use the elimination method to solve this
Multiply equation 1 by 3
(7x + 2y = 12.8) x 3 = 21x + 6y = 38.4
Multiply equation 2 by -2
(6x + 3y = 12) x -2 = -12x - 6y = -24
The x terms will cancel each other out
21x + 6y = 38.4
-12x - 6y = -24
9x = 14.4
Divide by sides by 9 to isolate the x variable
9x/9 = 14.4/9
x = 1.6
This means an apple costs $1.60
Plug the new x into one of the original equations to find y; we'll use equation 1
7(1.6) + 2y = 12.8
11.2 + 2y = 12.8
Subtract 11.2 from both sides
11.2 + 2y = 12.8
- 11.2 - 11.2
2y = 1.6
Divide both sides by 2
2y/2 = 1.6/2
y = 0.8
This means an orange costs $0.80

SAS
=========================================
Explanation:
SAS = side angle side
One pair of congruent sides is AC = CE (single tickmark). That takes care of one "S" of "SAS".
The other pair of congruent sides is BC = CD (double tickmark). This takes care of the other "S" of "SAS". The order of the "S" terms doesn't matter as long as the angles are between those sides.
The congruent pair of angles is angle ACB = angle ECD. Vertical angles are always congruent. Since we have a pair of congruent angles, this takes care of the "A" of "SAS". The angles are between the sides mentioned in the previous paragraphs.
In a city, 49% of the adults are male. Of the adults, 24% are male and rent action-movie DVDs and 10% are female and rent action-movie DVDs.
If an adult is randomly picked, the probability that the person rents action-movie DVDs, given that the person is female, is
.
Answers
Answer:
I getting the probability of the adult female that will rent the action movies in DVDs in by dividing the possible probability outcome which is 10% of all adults by the total number of possible outcome. So all of the population of the female is 51% and the ones who rent is only 10%. the probability is 19%
The solution is, 0.20 is the probability that the person rents action-movie DVDs, given that the person is female.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given that,
Data:
A: the adult is a male, P(A) = 0.49
B: the adult rent action-movie DVDs
C: the adult is a female, P(C) = 1 - P(A) = 1 - 0.49 = 0.51
24% of the adults are male and rent action-movie DVDs, then P(A ∩ B) = 0.24
10% of the adults are female and rent action-movie DVDs, then P(C ∩ B) = 0.10
The conditional probability of B (the adult rents action-movie DVDs) given C (the adult is female) is computed as follows:
P(B|C) = P(C ∩ B)/P(C)
= 0.1/0.51
= 0.2
Hence, The solution is, 0.20 is the probability that the person rents action-movie DVDs, given that the person is female.

2. [tex]\rm 9(x^2 + 6x) = 7[/tex]
3. [tex]\rm 9(x^2 + 6x + 9) = 7 + 81[/tex]
Given
The quadratic equation given as 9x^2 + 54x = 7.
Quadratic equation;The highest power of the degree is 2 is known as a quadratic equation.
To solve using the completing the square method.
The first three steps for solving the quadratic equation by completing the square are given below.
1. Write the equation in a way that the constants are on the right side while the terms with x are on the left.
[tex]\rm 9x^2 +54x = 7[/tex]
2. Make sure that the coefficient of the x^2 term is 1.
[tex]\rm 9(x^2 + 6x) = 7[/tex]
3. Adding a term to both sides that will complete the square on the left side.
This is done by dividing the coefficient of the x term by 2 and squaring it.
The same amount should be added to the right side to balance the equation.
[tex]\rm 9(x^2 + 6x + 9) = 7 + 81[/tex]

Raul works at a movie theatre. The function f(x) represents the amount of money Raul earns per ticket, where x is the number of tickets he sells. The function g(x) represents the number of tickets Raul sells per hour, where x is the number of hours he works. Show all work to find f(g(x))
Answers
Answer:
Step-by-step explanation:
Function f(g(x)) is the amount of money Raul earns per ticket sold.
here are the steps to find f(g(x)):
Define the functions f(x) and g(x).
f(x) = amount of money Raul earns per ticket
g(x) = number of tickets Raul sells per hour
Substitute g(x) for x in the function f(x).
f(g(x)) = amount of money Raul earns per ticket * number of tickets Raul sells per hour
Simplify the expression.
f(g(x)) = amount of money Raul earns per ticket * number of tickets Raul sells per hour
= amount of money Raul earns per ticket sold
Therefore, f(g(x)) is the amount of money Raul earns per ticket sold.
Here is an example:
Let's say f(x) = $10 and g(x) = 2 tickets/hour. If Raul works for 1 hour, he will sell 2 tickets and earn $20.
f(g(x)) = f(2) = $10 * 2 = $20
