The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
2900 individuals went to a b-ball game. 1769 individuals going to upheld the host group, while 1131 upheld the opposing group.
The percentage is given as,
P = (1131 / 2900) x 100

An investor flips a house, selling it for $88,000. If her profit was 30%, how much did she pay for the house originally? Round to two decimal places.
Answers
Answer:
She paid $67692.31 for the house originally.
Step-by-step explanation:
Let the initial cost of the house be [tex]x[/tex] dollars.
Given:
Selling price of the house (S.P) = $88000
Profit made = 30% of 'x' = [tex]0.30x[/tex]
We know that,
Profit = Selling Price - Original price
[tex]0.30x = 88000 - x[/tex]
Adding [tex]x[/tex] on both sides, we get:
[tex]0.30x+x = 88000\\\\1.3x=88000[/tex]
Dividing both sides by 1.3, we get:
[tex]x = 88000/1.3\\\\x = \$ 67692.307[/tex]
Rounding to 2 decimal places, we get:
[tex]x=\$67692.31[/tex]
Therefore, she paid $67692.31 for the house originally.

Step-by-step explanation:
Distribute:
3x+9-2x+2=5x-25
Combine like terms:
x+11=5x-25
Solve:
x-x+11=5x-x-25
11=4x-25
11+25=4x-25+25
36=4x
Divide by 9:
x=9.
Hope this helps :D
Answer:
x = 9
Step-by-step explanation:
Step 1: Solve both sides by distributing the values.
3x+9-2x+2 = 5x-25
Step 2: Put the like terms together.
3x-2x-5x = -25-9-2
-4x = -36
Step 3: Divide both sides by -4 to get the value of x.
[tex]\frac{-4x}{-4}[/tex] = [tex]\frac{-36}{-4}[/tex]
x = 9
Let's verify the answer.
3x+9-2x+2 = 5x-25
3(9)+9-2(9)+2 = 5(9)-25
27+9-18+2=45-25

Find the final sale price of a basketball that is $ 35 which is on sale for 50% and then gets an additional 10% off.
Answers
Answer:
$15.75
Step-by-step explanation:
$35 * 0.50 = 17.5
$35 - $17.50 = $17.50
$17.50 * 0.10 = $1.75
$17.50 - $1.75 =$15.75
Answer:
$15.75Step-by-step explanation:
To find the percent of a number, we need to express the percent as a decimal with the decimal point of the original percent moved two places to the left. We cannot add the two percents together. You are only paying 50% of the original price.
50% = 0.5
We will now move to decimal two places to the left.
0.005 x 35 = 17.50
Now, we find 90% (since we only care about the amount you are paying) of $17.50
0.009 x 17.50 = 15.75
$15.75A florist sells a dozen long-stemmed red roses for $54.99. In honor of their 16th wedding anniversary, a man wants to buy 20 roses for his wife. (Hint: How many roses are in one dozen?)
Let c represent the cost of 20 roses. Write a proportion, in terms of c, that can be used to solve for the cost of 20 roses.
What will the roses cost (in dollars)?
Answers
Answer:
20 roses cost $91.65
Step-by-step explanation:
Given
1 dozen rose = $54.99
Required
Determine the cost of 20 roses
To calculate the proportion, we make use of:
[tex]c = kx[/tex]
Where
c = cost
k = constant of proportionality
x = number of roses
For a dozen rose
[tex]c = 54.99[/tex] and [tex]x = 12[/tex]
So:
[tex]c = kx[/tex]
[tex]54.99 = k * 12[/tex]
[tex]54.99 = 12k[/tex]
[tex]k = \frac{54.99}{12}[/tex]
[tex]k = 4.5825[/tex]
For 20 roses
[tex]c = kx[/tex]
Where
[tex]k = 4.5825[/tex]
[tex]x = 20[/tex]
[tex]c = 4.5825 * 20[/tex]
[tex]c = 91.65[/tex]

[tex][f(x)]^2-g(x) = 5x^2-13x-8[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2x-2\\g(x) = -x^2+5x+12[/tex]
To find: [tex][f(x)]^2-g(x)[/tex]
First of all the square of first function f(x) will be found and then second function g(x) will be subtracted from the square of first function
Squaring the first function
[tex][f(x)]^2 = (2x-2)^2\\Using\ (a-b)^2 = a^2-2ab+b^2\\\[f(x)]^2 = (2x)^2-2(2x)(2)+(2)^2\\= 4x^2-8x+4[/tex]
Now subtracting g(x) from [f(x)]^2
[tex][f(x)]^2-g(x) = (4x^2-8x+4)-(-x^2+5x+12)\\\[f(x)]^2-g(x) = 4x^2-8x+4+x^2-5x-12[/tex]
Combining alike terms
[tex][f(x)]^2-g(x) = 4x^2+x^2-5x-8x+4-12\\\[f(x)]^2-g(x) = 5x^2-13x-8[/tex]
Hence,
Subtracting g(x) from the square of f(x) gives us:
[tex][f(x)]^2-g(x) = 5x^2-13x-8[/tex]

Conditional probability A provided B is generally written as:P(A/B)=P(A∩B)P(B)
Answers
Answer:
52 cards:
26 red and 26 black
P(R) = probability of picking a red card
P(B) = probability of picking a black card
P(R) = P(B) = ¹/₂
If with replacement:
P(R∩B) = (¹/₂)(¹/₂) = ¹/₄
If without replacement:
P(R∩B) = (¹/₂)(²⁶/₅₁) = ¹³/₅₁
8 Balls:
3 red and 5 white
P(R) = probability of picking a red ball
P(W) = probability of picking a white ball
P(R) = ³/₈
P(W) = ⁵/₈
If with replacement:
P(R∩W) ∪ P(W∩R) = (³/₈)(⁵/₈) + (⁵/₈)(³/₈)
= ¹⁵/₆₄ + ¹⁵/₆₄
= ³⁰/₆₄
= ¹⁵/₃₂
If without replacement:
P(R∩W) ∪ P(W∩R) = (³/₈)(⁵/₇) + (⁵/₈)(³/₇)
= ¹⁵/₄₂ + ¹⁵/₄₂
= ³⁰/₄₂
= ⁵/₇
