Answer:
50%
Step-by-step explanation:
The percent gain is calculated as
[tex]\frac{gain}{original}[/tex] × 100%
gain = 27 - 18 = 9 , then
percent gain = [tex]\frac{9}{18}[/tex] × 100% = [tex]\frac{1}{2}[/tex] × 100% = 50%

The ratio of hotdogs to hamburgers sold at the picnic was 3:4. If 98 dinners were sold, how many were hamburgers?
Answer:
56 Burgers
Step-by-step explanation:
First, add the 3 + 4 for a total of 7, because the total of the ratio will equal the total amount of "the dinners sold".
Then divide 98/7, which will give you 14.
Then in the ration 3:4, 4 represent burgers so multiply 14 x 4.
Which gives you 56 burgers.

the sum of person x and person y is 2640. if person x's income is 20% more than person y, find person x's income.
please answer fast fast plssssss as soon as possible
Answer:
I do not understand she question do you mean the sum of their income is 2640
if so, then the answer is 440 to be x income
Step-by-step explanation:
x income = 20% or 1/5 of y income
y income = 5 of x income
we know that the sum of their income = 2640
which means that
x + y = 2640 =
1/5y + y = 2640
6y/5 = 2640
cross multiply to give us
6y = 5(2640)
6y = 13200
divide through by 6 to give us,
6y/6 = 13200/6
y = 2200
since we know that x income is 20% y income,
therefore, x income =
20/100 * 2200
= 440
therefore,
x income = 440
y income = 2200
Answer:
1440Step-by-step explanation:
The equations to reflect the given:
x + y = 2640x = y + 20% ⇒ x = 1.2ySubstitute the value of x into first equation and solve for y:
1.2y + y = 26402.2y = 2640y = 2640/2.2y = 1200Find x:
x = 2640 - 1200 = 1440for questions 6-9 fill in the missing values on the doubled number line

5. Find the measure of the missing angle.
40°
50°
Step-by-step explanation:
40° + 90° + ? = 180°
130° + ? = 180°
? = 180° - 130°
? = 50°
Answer: 50 degrees
Step-by-step explanation: The interior angles add up to 180.
1. 40 + 90 + ? = 180
130 + ? = 180
-130 - 130
? = 50
4(5y-2) = 40
what is y?
Answer: 4(5y−2)=40
Divide both sides by 4.
5y−2=
4
40
Divide 40 by 4 to get 10.
5y−2=10
Add 2 to both sides.
5y=10+2
Add 10 and 2 to get 12.
5y=12
Divide both sides by 5.

Which of the following shows the factors of the polynomial f (x) = x^3 -11x + 6 , if one of those factors is x - 3
a. x - 3 is not a factor and there are no correct answers
b. f(x) = (x -3) ( x^2 - 8x - 18)
c. f(x) = (x -3) ( x^2 + 3x - 2)
d. f(x) = (x -3) ( x^2 - 3x^2 - 2x+12)
Answer: f(x)=(x-3)(x^2+3x-2)

How do I get the x and y intercepts to graph this equation?
Y=-1/2x-3
Answer: x intercept is (-6,0) and y intercept is (0,-3)
Step-by-step explanation: the y intercept is when x=0. the x intercept is when y=0.
to solve this for the y intercept, we set x=0 in the equation y=-1/2x-3. so it would be y=-1/2(0)-3 therefore y= 0-3 and y=-3. the y intercept is (0,-3)
to solve for the x intercept, we set y=0. we plug it into the equation y=-1/2x-3 so 0=-1/2x - 3. this means we can change the sign of -1/2x from negative to positive and move it to the other side. so 1/2x=-3 to solve for x, we divide both sides by 1/2 so x=-6. so the x intercept is (-6,0)
A number is 6 times another number and their sum is 28.what are the two numbers
Answer: Let the 2 numbers be x and
sum of two numbers is 28....Eq 1: x + y = 28
sum of 6 times the 1st number and 3 times the 2nd number is 105....Eq 2: 6x + 3y = 105
Rearrange Eq 1 to solve for x.
x + y = 28
x = 28 - y --> Substitute into Eq 2, you get
6(28 - y) + 3y = 105
168 - 6y + 3y = 105
-3y = -63
y = -63 / -3 = 21
Now solve for x using Eq 1.
x = 28 - y = 28 - 21 = 7

If three dice are rolled, what chance is there
of throwing a total of 3?
Answer:
Just as one die has six outcomes and two dice have 62 = 36 outcomes, the probability experiment of rolling three dice has 63 = 216 outcomes. This idea generalizes further for more dice. If we roll n dice then there are 6n outcomes.
We can also consider the possible sums from rolling several dice. The smallest possible sum occurs when all of the dice are the smallest, or one each. This gives a sum of three when we are rolling three dice. The greatest number on a die is six, which means that the greatest possible sum occurs when all three dice are sixes. The sum of this situation is 18.
When n dice are rolled, the least possible sum is n and the greatest possible sum is 6n.
There is one possible way three dice can total 3

The vertices of a triangle are P(7. -4), Q(-7, -8), and R(8,4). Name the vertices of the image
reflected in the y-axis.
Answer:
P' (-7, -4) , Q' (7, -8) , R' (-8, 4)
Step-by-step explanation:
Reflection in the y -axis:
The rule for a reflection over the y-axis is (x, y) → (−x, y).
P (7, -4) → P' (-7, -4)
Q (-7, -8) → Q' (7, -8)
R (8, 4) → R' (-8, 4)
What are the correct answers to this geometry question?
Answer:
x = 9
AB = 9
BC = 15
Step-by-step explanation:
x + x + 6 = 24
2x + 6 = 24
2x = 24 - 6
2x = 18
x = 18 / 2
x = 9
AB = x = 9
BC = x + 6
= 9 + 6
BC = 15
The Peyton family stayed in a hotel room for 5 nights while on vacation. The total cost before tax was $1,075. If the hotel room tax rate in the city is 14%, what was the total cost for the hotel room?
Answer:
1225.50
Step-by-step explanation:
14% of 1075 =0.14 x 1075=150.5
1075 +150.5 = 1225.5
The 14% of $1075 is $150.5 thus the total cost for the hotel room overall 5 nights including tax will be $1225.50.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
The total cost before tax was $1,075.
The tax rate is 14%
14% of $1075 will be,
(14/100)1075 = $150.5
Total cost includes tax = $1075 + $150.5 = $1225.50
Hence "The 14% of $1075 is $150.5 thus the total cost for the hotel room overall 5 nights including tax will be $1225.50".
