A. We know the amounts needed for 18 serving, so we can use proportions to scale this up to 108 cups. It is easy once you realize that 4 cups + 8 cups + 12 cups = 18 servings, and 18 * 6= 108, therefore you will need 6 times the amount of ingredients equally proportionated to each of the juices/seltezer. Therefore, we would need 24, 48, 72 cups of pineapple juice, orange juice, and seltzer.
b. Adding 4, 8, and 12 together, we get 24. 108 cups/24 cups of ingredients = 4.5 servings.
c. Using ratios, we see that we use 8 cups of orange juice for every 12 cups of seltzer. Dividing each side by 12, we get that we use 2/3 cups of orange juice for each cup of seltzer.
I'm guessing the question is "what's the equation"?
When slope and 1 point are known
Since it is a y-intercept then x=0 and the point is
(0,5)
b = y - mx
b = 5 --3 * 0
b = 5
Then we enter the slope and value of "b" into this equation
y = mx + b
y = -3x + 5
Answer:
Step-by-step explanation:
The formula of an area of a rectangle:
<em>l</em><em> - length</em>
<em>w</em><em> - width</em>
We have
Substitute:
Use FOIL <em>(a + b)(c + d) = ac + ad + bc + bd</em>
<em></em><em></em>
combine like terms
Answer: d=-3
Step-by-step explanation: -7-8d=17
-8d=17+7
-8d=24
-8d/-8=24/-8
D=-3
We know that 1 litre is equal to 1000ml (double the amount they're giving us), so 1 litre of paint is going to be $23 (we know this by multiplying 11.50 • 2).
Knowing this, all we need to do is multiply $23 • 4 which should give us $92.
So, the total of how much you will need to pay in this scenario to paint a room is $92 for 4 litres of blue paint.
Good luck!
