Answer:
C. {(2,4) (3,4) (4,4) (5,4) (6,4)} is a function.
Step-by-step explanation:
Since there is one value of y for every value of x in {(2,4) (3,4) (4,4) (5,4) (6,4)}, this relation is a function.
Step-by-step explanation:
each child gets a certain amount of items costing the specified price by item.
so, we need to multiply the number of children with the number of items with the price per item to get the total cost.
500×3×3.5 for pencils = 5,250
500×5×7.5 for notebooks = 18,750
500×1×21.75 for crayons = 10,875
500×2×9.26 for pad paper = 9,260
total 44,135
since we have only 1,200 available in the existing fund, we need a new one to cover the remaining
44,135 - 1,200 = 42,935
To find the average speed in miles per hour, you would divide the distance, 380 miles, by the time, 8 hours, in order to find the answer. Therefore the average speed should be 47.5 mph.
Answer:
A
Step-by-step explanation:
Put the ratios into fraction form. Since you do not know how many problems, replace it with an unknown number a.k.a. a variable.
10/30 = x/60
Since you can get 30 to 60 by multiplying by 2, multiply everything on the left side by 2.
Then, you get 20/60, which means 20 = x. So, he can complete 20 minutes an hour.
