A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18
Rashad took a test with 75 multiple - choice questions. If he got 9 questions incorrect,what is the ratio of the questions he got correct to the questions he got incorrect.
Step-by-step explanation:
If he got 9 questions wrong on a 75 multiple choices test, that means he got 66 right. That means the ratio to the questions he got correct to the questions he got incorrect is 66:9, or 22:3 simplified.
List all the numbers you can for (?) in the fraction ?/10. Each choice must be less then ten, and the fraction formed must be in simplest form [For the ones who can't read what it says.]

Step-by-step explanation:
7x - 2 = 5x + 14
Please help
Answer:
8
Step-by-step explanation:
7x - 2 = 5x + 14
7x - 2 - 5x = 5x + 14 - 5x
2x -2 = 14
2x -2 + 2 = 14 + 2
2x = 16
2x /2 = 16/2
x= 8
Hope this helps ^-^
Answer:
X=8
Step-by-step explanation:
7x - 2 = 5x + 14
Subtract 5x from both sides
2x-2=14
Add 2 to each side
2x=16
Divide by 2
x=8

What is the equation of this line?
y=2/3x
y=−3/2x
y=−2/3x
y=3/2x
Answer:
D. y=(3)/(2)x
Step-by-step explanation:
w=3x+7y solve for y in doing a class paper and im super confused
To solve for y, we need to isolate it. Start by moving all of the values on the side the y is on that don't have y to the other side (kind of confusing the way I said it). By that, I mean subtract 3x from both sides:
W = 3x + 7y
W - 3x = 7y
Now, divide both sides by 7 to find the value of y:
W - 3x = 7y
(W - 3x)/7 = y
Hope this helps! :)
Pete wants to treat several friends to the baseball game. he has a budget of $110. tikets are $8. he will spend $20 on parking how many friends can he afford to take without going over his budget?
Answer:
He can take 11 friends.
Step-by-step explanation:
110 - 20 = 90
Then you do simple math, how many times can 8 go into 90? Well, 8 times 10 is 80, so add 8 more and you have 88 (Which is 8 times 11).
90 - 88 = 2, so you can put in anymore.

Answer:
C = 106.76 cm
Step-by-step explanation:
In the diagram, we are given the diameter (d), which is 34 cm. Using the formula you are given, we know circumference is 3.14 × d
C = 3.14 × d
C = 3.14 × (34)
C = 106.76 cm
The circumference is around 106.76 cm
What is the measure of angle 2 if angle 1 is (5x - 2) and angle 2 is (2x)?
Answer:
52 degrees
Step-by-step explanation:
We're given:
Angle 1 = 5x-2Angle 2 = 2xThe sum of the two angles is 180 degrees, because they construct a straight edge together. A straight line has an angle measure of 180 degrees.
Knowing this, we can form the following equation and solve for x:
\(5x-2+2x=180\\7x-2=180\\7x=182\\x=26\)
Therefore, x is 26. Find 2x to find the measure of Angle 2:
\(2*26=52\)
Therefore, Angle 2 has a measure of 52 degrees.
Answer:
52
Step-by-step explanation:
Angle 1 and angle 2 are on a straight line so their measure add up to 180 and they are supplementary
m<1 + m<2 = 180
5x - 2 + 2x = 180 add like terms
7x - 2 = 180 add 2 to both sides
7x = 182 divide both sides by 7
x = 26
To find the measure of angle 2 replace x with the value we found
m<2 = 2x
2*26 = 52

So what is the question asking you?
The length of a building is 60 feet. The length of the building on a scale drawing is 4 inches. Which ratio describes the scale of the drawing?
-- giving brainliest to whoever has the answer (with descriptions and such)
-- if no one else answers (but only one person), i'll be able to give five stars and a thanks
the ratio of the scale drawing is
1 inch on the drawing represents 180 feet in real life.
To determine the ratio of the scale drawing, we need to first find the length of the building on the scale drawing. We know that the actual length of the building is 60 feet, and the length of the building on the scale drawing is 4 inches. We can set up a proportion to find the length of the building on the scale drawing:
Actual length / Length on scale drawing = Scale factor
We can plug in the values we know:
60 feet / Length on scale drawing in inches = Scale factor
To solve for the length on the scale drawing in inches, we can cross-multiply:
60 feet * 1 inch / Scale factor = Length on scale drawing in inches
Simplifying:
Length on scale drawing in inches = 60 feet * 12 inches / Scale factor
We know that the length on the scale drawing is 4 inches, so we can plug that into the equation:
4 inches = 60 feet * 12 inches / Scale factor
Solving for the scale factor:
Scale factor = 60 feet * 12 inches / 4 inches
Scale factor = 180
