Answer:
They will need √161 feet, or about 12.69 feet of fencing. √161 is irrational because 161 is not a perfect square.
Step-by-step explanation:




The question already gave you the formula in slope-intercept form (y=mx+b). You just need to graph it. Let’s begin with the easy step. The first point is the y-intercept (b) which is -5. Think of it as a point (0,-5), so you input -5 on the y-axis of the graph. After that is the slope, which usually is a fraction symbolizing rise over run. In this case, since the slope is a -x, is is -1 over one, therefore it’s down 1 right 1.
Step-by-step explanation:
the correct answer for the question is 85
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.
