You purchased concentrated cleaner that must be diluted (watered down) before use. Container A is the cleaner, which is a 20% solution. Container B is pure water. You are mixing together the contents of Container A and Container B to produce 40 gallons of 9% solution. How many gallons from each container are needed to create the 40 gallons of 9% cleaning solution? Write your answers as integers only.
Container A: 20% Cleaning Solution =
gallons
Container B: Pure Water =
gallons
Answer:
Amount of chemical solution = 18 gallon
Amount of pure water = 22 gallon
Step-by-step explanation:
Assume;
20% of solution = x
So,
Amount of pure water = 40 gallons - x
Amount of pure water = 40 - x
Computation:
20% of x = 9% of 40 gallon
0.2 x = 3.6
x = 3.6 / 0.2
x = 18 gallon
So,
Amount of chemical solution = 18 gallon
Amount of pure water = Total solution - Amount of chemical solution
Amount of pure water = 40 -18
Amount of pure water = 22 gallon
please helppp!!!!!!!!
Answer:
Angle 1 is 140.
Step-by-step explanation:
Set angle 1 and angle 3 equal to each other since they are congruent to each other to get this equation 20x+60=30x+20. Subtract 20x on both sides to get this equation 60 = 10x + 20. Subtract 20 on both sides to get to 40 = 10x. Divide 10 on both sides to get your x-variable which is 4. Since you are solving for angle 1, plug in the x-value to get 20(4)+60. You should get 140 degrees as your final answer.
Because your Christmas tree is bigger this year, you can decorate it with more ornaments! Last year, you put 35 ornaments on the tree. Since the tree is now bigger, you have room to increase the number of ornaments by 40%.
a. How many more ornaments can you put on the tree?
b. What is the total number of ornaments you are putting on the tree this year?
Answer:
You can put a total of 14 more ornaments this year.
The total number of ornaments you can put are 35+14= 49
Step-by-step explanation:
Answer:
See below :)
Step-by-step explanation:
a. This year, we know that the space increased by 40% of the last years.
Last year: 35 ornaments
This year: 35 ornaments + 40%(35) ornaments
We want to calculate 40%(35) so:
35 * 0.4 = 14
a answer. I can put 14 more ornaments on the tree.
b. In order to calculate the total ornaments, we want to add last year's + the new space
We already calculated 40%(35) is 14 so all we have to do is add 35 and 14:
35 + 14 = 49
b answer. The total number of ornaments I can put on the tree this year is 49.

Step-by-step explanation:
Answer:
Just subtract, 400 - 50 = 350, 350 - 50 = 300....etc until you reach (8,0) point on the graph. Graph a straight line down from starting point (0,400) on graph to (8,0). This is your answer subtract 50 from 400 until you reach 0. Starting point (0,400) and ending point (8,0), it's a straight line down ward..

ASAP!!! 135 5 - 4 (3x + 31) (7x - 64) (4x + 15) (6x - 8) 120° Q. Solve for X.
Answer:
X=3
Step-by-step explanation:
this is a heptagon (7sides) so all the angles must add to 900 degrees
you have to add them all up
135+(5x-4)+(3x+31)+(4x+15)+(6x-8)+120+(7x-64)=900
25x+225=900
25x+225-225=900
25x=675
25x/25=675/25
x=3
The value of x in the given hexagon is 19.8°.
What is a polygon?A polygon is a closed more than two-sided and can be made up of a finite number of straight line segments and is a type of planar figure in geometry.
Each line of the polygonal circuit's segments is referred to as its edges or sides.
We know the sum of interior angles in a hexagon is 720°.
∴ 135° + (5x - 4)° + (3x + 31)° + (7x - 64)° + (4x + 15)° + (6x - 8)° + 120° = 720°.
5x + 3x + 7x + 4x + 6x = (720 - 135 + 4 - 31 + 64 - 15 + 8 - 120)°.
25x = 495°.
x = 19.8°.

Write the equation of a line in point-slope form that is parallel to the line y=2x-5 and goes through the point (-1,4)
(y-4) = 2(X+1)
Step-by-step explanation:
Hey there!
The given eqaution is; y = 2x-5.......(i)
Now; As the eqaution is in the form of y= mx+b.
Slope(m1) = 2.
As per the condition of parallel lines, slope of the 1st equation (m1) = slope of 2nd eqaution (m2).
Therefore, m1= m2= 2
Now, use one point formula for finding the eqaution of the line which passes through the point.
(y-y1) = m2(x-x1)
~ Put all values.
(y-4) = 2(X+1)
You can simply write upto here. But it you want to make it simplified form then, (look below)
~ simplify it.
y = 2x +2+4
The eqaution of the line which is parallel to y = 2x -5 and point (-1,4) is y = 2x + 6.
Hope it helps.....
Answer: y - 4 = 2(x + 1)
Step-by-step explanation:
The point slope form formula says that y - b = m(x-a) where m is the slope,b is the y coordinate of a given point , and a is the x coordinate of the same point.
Remember that parallel lines have the same slopes but different y-intercepts, meaning that m will equal to 2 because the slope for the line y=2x-5 is 2.
m will be 2, b will be 4 , and a will be -1.
y - 4 = 2(x - (-1) which reduces to
y - 4 = 2(x + 1)

Which shows the result of a correct substitution for the system y=2x+3 and 3x+2y=9?
Answer:
The result of the correct substitution gives:
x = 3/7 and y = 27/7
Step-by-step explanation:
From the given information:
y = 2x + 3 ---- (1)
3x + 2y = 9 ---- (2)
By using substitutional method
Substitute the value of y = 2x +3 into equation (2)
So,
3x + 2(2x + 3) = 9
3x + 4x + 6 = 9
7x = 9 - 6
7x = 3
x = 3/7
From equation (1), let replace the value of x to be 3/7
So,
y = 2x + 3
y = 2(3/7) + 3
y = 6/7 + 3
y = 27/7
