Step-by-step explanation:
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

An American traveling in Japan wishes to exchange American money for Japanese money. If the exchange rate is $1 = 80 yen, then how many dollars will the traveler need to purchase 10,000yen?
Answer: $125
Step-by-step explanation:
1/80=x/10,000
10,000/80=125
Hope this helped!
Answer:125 yen
Step-by-step explanation:
Ratio and proportion
Ratio=1:80=x:10,000
x represents dollars which is unknown
1/80=x/10,000
Then you cross multiply
80x=10,000
80x/80=10,000/80
x=125
Therefore,$125 will give you 10,000yen

Answer:
x=14, angle= 128 degrees
Step-by-step explanation:
The two angles are equal to each other so you can set the equations equal.
7x+9=9x-19
Now solve for x:
28=2x
x= 14
Plug 14 back into an equation, so 7(14)+9=128 degrees.
Solve the side angel for x.
Answer:
x=80
Step-by-step explanation:
a^2+b^2=c^2
48^2+64^2=x
2304+4096=x
6400=√x
√ to get x alone
80=x

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.
The tallest trees in the world are redwoods (Sequoia sempervirens), which tower above the ground in California. These trees can easily reach heights of 300 feet.
If you draw a scale model of this tree and it is 6 inches tall, what would your scale be? Explain your reasoning.
Answer:
1 inch : 50 feet
Step-by-step explanation:
Usually when you are asked for a scale you need the first number to be a.
With that in mind, we simply have to bring 6 inches : 300 feet down to a 1 inch : 50 feet
aka 6/6 and 300/6
Answer:
2 inches : 100 feet
Step-by-step explanation:
Usually when you are asked for a scale you need the first number to be a.
We have to bring 12 inches : 300 feet down to 2 inches : 100 feet
or 6/6 and 300/12
A particular movie theater charges $7.00 per adult and $4.50 per child. Suppose 450 people attended a movie and the total revenue from ticket sales was $2650. Write linear equations for the two constraints, where z represents the number of adults attending the
movie and y represents the number of children attending the movie. 1= ,2=?
Answer:
7z + 4.5y = 2650
z + y = 450
Step-by-step explanation:
The first equation represents the amount of money made from ticket sales for both adult and child tickets.
The second equation represents the amount of customers, both adult and child, that attended the theatre.
Using both equations you cans find the number of adults and children that attended the theatre.
Cheers.
-----------------------------------------------------
Edit: Solving for the variables
There are two easy ways to solve for these values. The first is using an augmented matrix and solving with that method.
7 4.5 | 2650
1 1 | 450
After are augmented matrix is set up, we simply use row operations on the matrix to solve for 1s on the diagonal.
The second method for solving is equation addition or variable substitution to solve for each variable.
7z + 4.5y = 2650
z + y = 450
7(450-y) + 4.5y = 2650
3150 - 7y + 4.5y = 2650
-2.5y = -500
y = 200
Plug back in y into one of the equations to solve for z.
z + 200 = 450
z = 250
So there were 250 adults and 200 children.

Answer:
91
Step-by-step explanation:
There is a rule that says that 129 = 38 + x
so x = 129 - 38
x = 91
Answer:
x = 91.
Step-by-step explanation:
129 = x + 38
First, we can subtract 38 from both sides to get:
91 = x
So the solution is x = 91.
