A 3-gallon container of window cleaner costs $15.84. What is the price per quart?
*Hint: 1 gallon = 4 quarts*
HURRY DUE SOON PLEASE AND THANK YOU :)
Answer:
1.32
Step-by-step explanation:
3 gallon = 1
12 quarts = 4
12 quarts =1
$15.84= 1.32
Answer:
$1.32 per quart
Step-by-step explanation:
To find the price per quart, we must divide the price by the number of quarts.
price / quarts
We are told that a 3 gallon container costs $15.84. First, we must find out how many quarts are in 3 gallons.
We know that 1 gallon is equal to 4 quarts.
Let’s set up a proportion.
quarts/ gallons = quarts/ gallons
4 quarts /1 gallon = x quarts/ 3 gallons
4/1= x/3
Multiply both sides by 3
3*4/1= x/3*3
3*4/1=x
3*4=x
12=x
There are 12 quarts in 3 gallons.
Now we know how many quarts are in 3 gallons. We can find the price per quart.
price / quarts
It costs $15.84 for 12 quarts.
$15.84/12 quarts
Divide 15.84 by 12
$1.32 / quart
It costs $1.32 per quart of window cleaner.

What is the simplified form of the expression? 6/√5−√2
Answer:
The expression can be simplified into [tex]2\,\sqrt{5} +2\sqrt{2}[/tex]
with no square roots in the denominator
Step-by-step explanation:
We are considering the expression [tex]\frac{6}{\sqrt{5}-\sqrt{2} }[/tex] which I believe is what you wanted to type in your question.
The idea behind simplification of the expression, is normally associated with the rationalization of the denominator by eliminating irrational numbers from it. This means to get rid of any "irrational" number expression (like in this example, the square root of non-perfect square numbers ([tex]\sqrt{5}\,\,\,and \,\,\sqrt{2}[/tex]).
We proceed by writing this quotient in an equivalent form by multiplying its numerator and its denominator by what is called the "conjugate" of the denominator. In our case, multiply by " [tex](\sqrt{5} +\sqrt{2})[/tex] ", because such product will allow the denominator to become a rational number:
[tex]\frac{6}{\sqrt{5}-\sqrt{2} }\,*\,\frac{(\sqrt{5}+\sqrt{2} )}{(\sqrt{5}+\sqrt{2}) } =\frac{6\,(\sqrt{5}\,+\,\sqrt{2} )}{\sqrt{5}^2-\sqrt{2}^2 }=\frac{6\,(\sqrt{5}\,+\,\sqrt{2} )}{3}=2\,\sqrt{5} +2\sqrt{2}[/tex]
where we find all square roots eliminated from the denominator

Find the value of X
Plz help me it’s emergency
Answer:
x = - 2
Step-by-step explanation:
Using the rules of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex]
[tex]\frac{a^{m} }{a^{n} }[/tex] = [tex]a^{(m-n)}[/tex]
Evaluating the numerator
9³ × 9 = [tex]9^{(3+1)}[/tex] = [tex]9^{4}[/tex] , thus
[tex]\frac{9^{4} }{9^{6} }[/tex]
= [tex]9^{(4-6)}[/tex] = [tex]9^{-2}[/tex]
and [tex]9^{-2}[/tex] = [tex]9^{x}[/tex]
Since bases on both sides are 9, then equate exponents
x = - 2

The domain of the function f(x) = 3x3 is {2, 5}. What is the function’s range?
The range of the function f(x) = 3x3 when its domain is {2, 5} is
Answer:
[tex]Range = [24, 375][/tex]
Step-by-step explanation:
Given
[tex]f(x) = 3x^3[/tex]
[tex]Domain = [2,5][/tex]
Required
Find the Range
The range is calculated by solving for f(2) and f(5). In other words, the range is calculated when x is 2 and x is 5
When x = 2;
f(2) is as follows;
[tex]f(2) = 3*2^3[/tex]
[tex]f(2) = 3 * 8[/tex]
[tex]f(2) = 24[/tex]
When x = 5;
f(5) is as follows;
[tex]f(5) = 3*5^3[/tex]
[tex]f(5) = 3 * 125[/tex]
[tex]f(5) = 375[/tex]
Hence, the range of the function is [24, 375]

A truck can be rented from Company A for $120 a day plus $0.70 per mile. Company B charges $80 a day plus $0.90 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answer:
200 miles
Explaination:
in order to fiind the point of interaction you must put the world problem into an liner equation.
y=mx+b
key:
miles : x
y= 0.70x + 120
&
y= 0.90x + 80
now you put them together
0.70x + 120 = 0.90x + 80
-0.70x. -0.70x
____________________ subtract slope from both sides
120 = 0.20x + 80. ( doesn't matter which one)
-80 - 80
____________________ subtract
40 = 0.20x
_________ Divide each # with the slope
0.20 0.20
200 = x

4(2+a)=24 what is the answer
Given:
4(2 + a)= 24
Use Distributive Property:
8 + 4a = 24
Subtract 8 to both sides:
4a = 16
Divide 4 to both sides:
a = 4
Answer:
A = 4
Step-by-step explanation:
Assuming the question is asking what a is, then all you have to do is follow a few steps to get the right answer.
1) Use the distributive property to simplify the first part of the equation.
4(2+a) distribute the 4 to what is within the parenthesis, so multiply 4 to what is in the parenthesis. P.S: This also gets rid of the parenthesis.
(8 + 4a)
2) Now your equation looks like 8 + 4a = 24. Now, use inverse operations to isolate a. Inverse operations are basically using the opposite signs and processes to get some parts of an equation to another side.
2a. Subtract 8 from both sides of the equation:
8 + 4a - 8 = 24 - 8.
So now you have 4a = 16.
2b. Divide 4 from both sides of the equation.
4a/4 = 16/4
So now you have a = 4.
Final answer:
A = 4

Answer:
C : 414.7
Step-by-step explanation:
I do not completely know if this is right or not, but I used reasoning to figure this out. I can easily find the area of a circle just based on the radius of it, and the radius of the circle (all parts included) is 452.39. And since the percentage of the shaded circle would have to be a lot larger to have the unshaded area only be 188, then I can reason that 414.7 would be the most reasonable answer.

A local car dealer has 150 cars on the lot. 30% of the cars are sedans. How many of the cars are NOT sedans?
Answer:
105 cars
Step-by-step explanation:
150cars=100%
and if 30% of the cars are sedans then the cars which are not sedans is
100%-30% =70%
if 150 cars=100%
? cars=70%
if less more devides
70%/100%×150cars
all zeros cancel which would be left with
7× 15
105 cars.
Answer:
The answer is 105
So that 30% of those cars are 45 Sedans of the 150 cars.
Now we need to find out how many cars are in that remaining 70%
In order to do this we need to subtract 45 from 150
So 150 minus 45 is 105
Finally, we know that that remaining 70% is 105 cars that aren't Sedans.
So 105 cars are not Sedans.

What information is missing but is needed to solve this problem?
The community theater staged performances on Friday, Saturday, and Sunday. There were 357 people at Friday's performance and 422 at Sunday's performance. How many people attended Saturday's performance?
A)the number of people at Friday's, Saturday's, and Sunday's performances combined
B)the number of people at Friday's and Sunday's performances combined
C)the difference between the number of people at Friday's and Sunday's performances
D)the average of the number of people at Friday's and Sunday's performances
Answer:
a. the number of people at Friday's, Saturday's, and Sunday's performances combined.
Step-by-step explanation:
The reason this information is needed to solve this problem is because we are looking to find the number of people who attended Saturday's performance. Without any information on Saturday's performance, there is no way to solve the problem. We are given the number of people on Friday and Sunday's performance, but are not given a total amount of people on all performances.
Answer:
A) The number of people at Friday's, Saturday's, and Sunday's performances combined.
Step-by-step explanation:
We are looking for the amount of people who attended Saturday's performance, but only one of the answers contains anything about Saturday, which is A. All the information in the other 3 choices we already know, because we know the amount of people at both Friday and Saturday's performance, so we can do some simple math to figure it out.

A bluebird house should have a 5 inch by 5 inch floor, a height ranging from
8 inches to 12 inches, and an opening of 1.5 inches. Bluebirds like open areas,
such as fields, large lawns, cemeteries, parks, and golf courses. Hanging a
bluebird house on a post or pole about 4 or 5 feet above the ground will
probably attract the birds and offer them protection from predators.
In Exercises 1–5, use the following information.
Your woodshop class is making bluebird houses for a final project. A model of
the birdhouse is shown below. The roof consists of four congruent triangles, the
sides are made of four congruent isosceles trapezoids, and the base includes four
rectangles and a square bottom.
1. Find the area of material needed to
make the roof.
2. Find the area of the entrance hole.
3. Find the area of material needed to
make the sides of the birdhouse,
excluding the entrance hole.
4. Find the area of the material needed
to construct the base of the birdhouse.
5. What is the total amount of material
needed for the entire birdhouse?
Answer:
1. 140 in²
2. 2.25 in²
3. 182 in²
4. 55 in²
5. 374.75 in²
Step-by-step explanation:
1. Area of each triangle: 10*7*1/2 = 35 in²
Area of the roof = 4*35 = 140 in²
2. Area of the entrance hole: 1.5*1.5 = 2.25 in²
3. Area of each trapezoid: (8+5)/2*7 = 45.5 in²
Area of the sides: 4*45.5 = 182 in²
4. Area of the square of the base: 5*5 = 25 in²
Area of each rectangle: 1.5*5 = 7.5 in²
Area of the four rectangles = 4*7.5 = 30 in²
Area of the base: 25 + 30 = 55 in²
5. The total amount of material needed for the entire birdhouse is: 140 - 2.25 + 182 + 55 = 374.75 in²

If xy>0, then the points of P(x,y) lies...
Answer:
In Quadrant I or III
Step-by-step explanation:
We know if the sign was not showing closed inequality facing other way
xy < 0 would be in the 2nd or 4th quadrant.
If xy = 0 then either xy or both are on the x or y axis
But if xy>0 then they are in quadrant I or III
If xy>0, then the points of P(x,y) lies in Quadrant I and III
Quadrants on the Cartesian planeAccording to the given condition;
xy > 0This means that the product of x and y is a positive number.
Hence, either both x and y-coordinates are positive or are both negative
Hence, only points in the Quadrant I have positive x and y coordinates Or Quadrant III in which case all x and y values are negative.
