3. Over the weekend, Jada made three times as much money babysitting than Han did mowing lawns. Jada made an additional $27 selling lemonade. From babysitting and selling lemonade, she has a total of $96. If the equation 3x + 27 = 96 represents this situation, what does the variable x represent?
Answer:
X is the amount Han made mowing lawns
because it said that she earned 3xs the amount he did. So you would take what he made times three plus the extra 27 she made from selling lemonade
Can someone help me solve pleaseeeee? Asap
Answer:
[tex]\frac{4}{5}[/tex]
Step-by-step explanation:
Given
[tex]\frac{12x-4}{15x-5}[/tex] ← factorise numerator and denominator
= [tex]\frac{4(3x-1)}{5(3x-1)}[/tex] ← cancel (3x - 1) on numerator and denominator
= [tex]\frac{4}{5}[/tex]
Jensen has an above ground pool in the shape of a regular octagon. Opposite sides are 25 feet apart and each side is 10.4 feet long. It requires 7.5 gallons to fill one cubic foot. How much water is need to fill the pool with 3 feet of water.
A. 3900
B. 5850
C. 1560
D. 11700
Answer:
D
Step-by-step explanation:
To solve this question we can use the area formula for an octagon.
It is as follows:
A=2(1+√2)a^2
where "A" is the total area and "a" is the length of a side.
Plug in our side length a=10.4
A=2(1+√2)10.4^2
≈522.24268
Alternatively, you can split the octagon into 8 equal triangles.
The base of each triangle would be 10.4 and the height would be 12.5 since opposite sides are 25 feet apart. (25/2)
The area of a triangle would then be:
A=1/2bh
where "b" is base and "h" is height
A=125*10.4*1/2
=65
Since there are 8 we multiply that by 8 for the area of an octagon
65*8=520
The area of the octagon base is 520 square feet.
I'll use this value to do my calculations as it is more exact.
Now, using this area, we need to find the volume of the pool we are meant to fill.
To do this, we simply multiply the area of the base by the height.
520*3=1560
Now, we know that the volume of the pool is 1560 cubic feet.
Each cubic foot takes 7.5 gallons to fill.
1560*7.5=11700
Therefore, the pool takes 11700 gallons of water to fill.
2.Mauricio tanqueó su auto en una estación de gasolina. Si el galón costo $ 7.000 y él pagó 12.250 por el servicio, ¿Qué fracción indica la cantidad de galones que pagó Mauricio?

2.Mauricio llenó su auto en una gasolinera. Si el galón le costó $ 7,000 y él pagó 12,250 por el servicio, ¿qué fracción es la cantidad de galones que pagó Mauricio?
La fracción por la cantidad de galones que pagó Mauricio se calcula como:
Cantidad de galones / Cantidad total pagada por el servicio
= $ 7000 / $ 12,250
= 4/7
Por lo tanto, la fracción que es la cantidad de galones que pagó Mauricio es 4/7

Answer:
Angle A = 15°
use angle properties of triangle to solve this.
Step-by-step explanation:
Given Angle CBD = 30,
Angle ABC + Angle CBD = 180 (Sum of Angles on the same straight line)
Angle ABC + 30 = 180
Angle ABC = 180 - 30 = 150
Since Angle AB =~ BC,
Angle A = Angle C
Let angle A and C be x.
Angle A + Angle C + Angle ABC = 180 (Sum of Angles in a triangle)
[tex]x + x + 150 = 180 \\ 2x + 150 = 180 \\ 2x = 180 - 150 \\ 2x = 30 \\ x = 15[/tex]
Therefore Angle A = 15 degrees

2 Fat-free cottage cheese is sold in quantities of 125 g at R8,99.
Calculate the cost of the fat-free cottage cheese required in the recipe.
Answer:
R17.98
Step-by-step explanation:
Required in the recipe = 250 g Fat free cottage cheese ;
125 g Fat free cottage cheese = R8.99
For 250g Fat free cottage cheese ; 250 / 125 = 2 125 g fat free cottage cheese is required ;
1 125 g Fat free cheese =. R8. 99
2 125g fat free cottage cheese =. R8. 99 * 2
R8. 99 * 2 = R17.98

Answer:
Set this up as a proportion.
54/n = 75/100
Now solve for n and finish from here.
Can i also have brain or a heart :)
Answer:
x would equal 72
Step-by-step explanation:
you can find a percent but there is already a percent showing. So the answer should be 72.
When you're trying to find the answer to these problems you should check if there is a percent part and whole. In this question, there is already a percent and a part so you would just try to find the whole.

James scored a total of 16 points during a basketball game. During the game, he made only free throws, worth 1 point each, and 3-point baskets. He made a total of 10 free-throws and 3-point baskets. Determine exactly how many free throws and how man 3-point basket James made during the game.
Answer:
x = 7 , y = 3 , or 7 free throws, and 3 3-pointers.
Step-by-step explanation:
James scored a total of 16 points during a basketball. Only free throws and 3-point baskets are used. Free throws = 1 point (x), 3-pointers = 3 points (y).
Set the equations:
16 = x + 3y
10 = x + y
First, isolate the variable x in the second equation. Divide y from both sides of the equation:
10 (-y) = x + y (-y)
x = 10 - y
Next, plug in 10 - y for x in the first equation:
16 = x + 3y
16 = (10 - y) + 3y
Simplify. Combine like terms:
16 = 10 - y + 3y
16 = 10 + (-y + 3y)
16 = 10 + 2y
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, subtract 10 from both sides of the equation:
16 (-10) = 10 (-10) + 2y
2y = 16 - 10
2y = 6
Next, divide 2 from both sides:
(2y)/2 = (6)/2
y = 6/2 = 3
Plug in 3 for y in one of the equations:
16 = x + 3y
16 = x + 3(3)
16 = x + 9
Isolate the variable, subtract 9 from both sides of the equation:
16 (-9) = x + 9 (-9)
x = 16 - 9
x = 7
x = 7 , y = 3 , or 7 free throws, and 3 3-pointers.
Plug in to check:
16 = x + 3y
10 = x + y
16 = (7) + 3(3)
16 = 7 + 9
16 = 16 (True)
10 = (7) + (3)
10 = 10 (True).

Answer:
x = 7 , y = 3 or 7 free throws, and 3 3-pointers.

Pictures attached-- 100 points!! Assuming that any increase occurs in whole dollar amounts, what is the maximum possible increase that maintains the desired minimum revenue? Explain why this is true.
Answer:
Part A:
Cost: 10+x
Customers: 16 - 2x
Part B:
-2x^2+-4x+160 ≥ 130.
Part C:
$12
Part D:
$12 because it is greater.
Step-by-step explanation:
To know how to solve you do this
Put each number from part c like 13 is 3 and change the x
for example
-2(x)^2-4(x)+160
to
-2(3)^2-4(3)+160
Is it greater than ≥ 130 or equal to?
What evera is greater to is the answer.
