Everyone will have juice in party and you have 10 liters of a juice blend (mixture of
pure juice and water) that is 60% pure juice.
1. How many liters of pure juice need to be added in order to make a blend that is 75% juice?
2. How many liters of pure juíce need to be added in order to make a blend that is 90% juice?
Answers
Answer: you added 6 liters of juice
Step-by-step explanation:
You have 10 liters of a juice blend that is 60% juice. How many liters of pure juice need to be added in order to make a blend that is 75% juice?
Ten liters of a juice blend at 60% juice means you also have ten liters of a juice blend at 40% water. 10 x .40 yields 4 liters of water in your blend.
A juice blend of 75% has a water content of 25%. So the same 4 liters of water must represent 25% of the blend after adding more juice.
4/.25 = 16 liters. 16 x .75 = 12.
12 + 4 = 16.
That means after adding your juice you will have 16 liters of blend at 75% juice.
You originally had 10 liters at 60% and now you have 16 liters at 75% . Subtracting 10 from 16 means you added 6 liters of juice.

Solve the system of equations below by graphing.
y= x - 3
y=-5/2x + 4
Answers
x-3 = -5/2 +4
Multiply both sides of equation by 2 to remove the fraction...
2(x-3)= 2(-5/2x+4)
2x-6 = -5x+8
Move the terms together...
2x+5x = 8 + 6
7x = 14
So....
x = 2
1. what is the equation of a line that has an x-intercept of 2 and a y-intercept of 8
Answers
Answer:
B
Step-by-step explanation:
x- intercept = 2 .So, Coordinate(2 , 0)
y-intercept = 8 . So, Coordinate (0, 8)
[tex]Slope = \frac{8-0}{0-2}\\\\=\frac{8}{-2}\\\\=-4[/tex]
Slope y-intercept form: y = mx + b {Here, b is y-intercept}
y = -4x + 8
Find the equation of the circle that has center (-4,3) and passes through 3,-3
Answers
Answer:
(x+4)^2+(y-3)^2 = 85
Step-by-step explanation:
The standard form of equation of a circle is expressed as;
(x-a)^2 + (y-b)^2 = r^2
(a, b) is the center
r iis the radius
Get the radius
Radius is the distance between the two points
r^2 = (-3-3)^2 + (3-(-4))^2
r^2 - (-6)^2+(7)^2
r^2 = 36+49
r^2 = 85
Substitute (-4, 3) and r^2 = 85 into the formula
(x-(-4))^2 + (y-3)^2 = 85
(x+4)^2+(y-3)^2 = 85
This gives the required equation

Three cylinders have a volume of 2826 cm. Cylinder A has a height of 900 cm. Cylinder B
has a height of 225 cm. Cylinder C has a height of 100 cm. Find the radius of each cylinder.
Use 3.14 as an approximation for T.
Answers
Answer:
the radius of each cylinder is 1 cm, 2 cm and 3 cm respectively
Step-by-step explanation:
The computation of the radius of each cylinder is shown below:
As we know that
The Volume of the cylinder = πr^2h
The radius would be
[tex]=\sqrt{ \frac{V}{\pi h} }[/tex]
For cylinder A
[tex]=\sqrt{\frac{2826}{3.14\times 900} }[/tex]
= 1 cm
For cylinder B
[tex]=\sqrt{\frac{2826}{3.14\times 225} }[/tex]
= 2 cm
For cylinder C
[tex]=\sqrt{\frac{2826}{3.14\times 100} }[/tex]
= 3 cm
Hence, the radius of each cylinder is 1 cm, 2 cm and 3 cm respectively

Choose all the properties of a square
Answers
Answer:
Opposite sides are parallel. All sides are congruent. All angles are congruent. Diagonals bisect each other. Consecutive angles are supplementary. Diagonals are perpendicular and congruent.
Step-by-step explanation:
A square is a special shape in which all angles, sides, and diagonals are congruent to one another. Therefore, all sides and angles are congruent, the diagonals cross in the middle of the square making them perpendicular, the diagonals bisect each other in the middle, and they are supplementary because they are parallel.

WalMart offered a 15% discount off the regular price of a Ice Cream Maker. The amount of the discount is $5.00. What is the regular price of the Ice Cream Maker?
Answers
Answer:
$33.33
Step-by-step explanation:
We are told in the above :
WalMart offered a 15% discount off the regular price of a Ice Cream Maker.
The amount of the discount is $5.00.
The formula for Percentage Discount =
Discount/Original amount × 100
Original amount = x
Hence:
$5/x × 100 = 15%
= 5/x = 15/100
Cross Multiply
5 = 0.15 × x
5= 0.15x
x = 5/0.15
x = $33.33
Therefore, the regular price of the Ice Cream Maker is $33.33
