What is the answer to this word problem, Samantha is using a 2 liter pitcher to serve lemonade to 10 of her friends. How many times will she need to fill the pitcher in order to serve each friend 400 milliliters of lemonade?

2

Step-by-step explanation:

10 friends each served 400 ml of lemonade consumes 400 x 10 = 4000 ml = 4 l of lemonade in total

Pitcher size is 2 l therefore 4 / 2 = 2 pitchers are required assuming no losses.

Step-by-step explanation:

The pitcher is 2 liters. 400 milliliters=0.4 liter. There are 10 friends so multiply 400 by 10. That's 4000 milliliters which is 4 liters. Therefore you would have to refill it once to be able to server each friend 400 milliliters.

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
