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
Answers
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

Sheldon can read 9 pages in 15 minutes. Betty can read 18 pages in 1 hour. Explain how you could use a table or graph to
find how much longer it would take Betty to read a 360-pageants book than Sheldon.
Make a table of
Betty hours longer to read the book.
Answers
First step, make ratios:
Pages: time
Sheldon: 9 pages: 15 minutes
Betty: 18 pages: 60 minutes (1 hour)
To find how long it would be for 360 you divide:
9/15 is 0.6 pages: 1 minute and 18/60 is 0.3 pages per minute
When you make the table here would be the equation:
y=.06x for Sheldon and y=.3 for betty (plug in times and create a table)
Evaulate each expression when n = 2.3
N + 8n2 - 17=
Answers
Answer: 27.62
Step-by-step explanation:
plug in 2.3 wherever 'n' is
I'm assuming that the '2' in 8n2 is an exponent
2.3 + 8(2.3)² - 17 =
Using PEMDAS
start out with exponent since there isn't any parenthesis
(2.3)² = 5.29
2.3 + 8(5.29) - 17
move on to multiplication
8(5.29) = 42.32
2.3 + 42.32 - 17
with addition and subtraction, you do whichever comes first and since this equation starts with addition we'll start there
2.3 + 42.32 = 44.62
then the subtraction
44.62 - 17 = 27.62
Answer:
Step-by-step explanation:
The answer is 27.62

{(−4, −4), (−4, −1), (−2, −4), (−1, −4), (0, 0)}
Answers
Answer:
\(\huge\boxed{\sf Option \ 1}\)
Step-by-step explanation:
For a relation to be a function,
the x-values (domain) in that relation should not repeat.So,
Here, the set of ordered pair that represents a function is:
{(−4, −4), (−3, −3), (−2, −2), (−1, −1), (0, 0)}Because in this set:
Domain = {-4, -3, -2, -1, 0}
Also, the values in the domain are not repeated. So, this set is a function.

Given that 1+5b+9c=1 , 4a+2b+3c=2, 7a+8b+6c=9
what is 741a + 825b + 639c?
Answers
Answer:
741a + 825b + 639c = 1375/9.
Step-by-step explanation:
To solve this problem, we need to first find the values of a, b, and c that satisfy the given system of equations. We can use any method of solving systems of linear equations, such as substitution or elimination. Here, we will use the elimination method:
Multiplying the first equation by -4 and adding it to the second equation, we get:
-20b - 36c = -2
Multiplying the first equation by -7 and adding it to the third equation, we get:
29b + 45c = 8
Multiplying the second equation by -29/20 and adding it to the third equation, we get:
-21b - 39c = 67/10
Now we have three equations in two variables. We can solve for b and c using any method, such as elimination or substitution. Here, we will use substitution:
From the second equation, we can solve for a in terms of b and c:
a = (2 - 2b - 3c)/4
Substituting this expression for a into the third equation, we get:
741/4 - 825/2 b + 639/6 c = 9
Simplifying and solving for b, we get:
b = (3/5) - (3/5) c
If this helps, please mark my answer as brainliest
Substituting this expression for b into the second equation, we get:
(27/5) c = (2/5)
Solving for c, we get:
c = -(2/27)
Substituting this value of c into the expression for b, we get:
b = (3/5) - (3/5) (-2/27) = (11/27)
Substituting the values of a, b, and c into the expression 741a + 825b + 639c, we get:
741a + 825b + 639c = 741[(2 - 2b - 3c)/4] + 825b + 639c
= 741[(2 - 2(11/27) - 3(-2/27))/4] + 825(11/27) + 639(-2/27)
= 741(5/27) + 275/3 - 426/9
= 1375/9
Therefore, 741a + 825b + 639c = 1375/9.

Explanation:
Step 1: bring -8 to the left since it is less than 10. It would now be 18+8m= -10.
Step 2: you would then move 8 to the right side since you want them to be equal on both sides. it would now be 18= -18m
Step 3: Finally, you divide -18 since you want to find m;you would need to separate them
