Since it takes less time in September than in June, this is a DECREASE. The percent decrease. The time is different by 114 seconds, divide this by the original time of 465 seconds and then convert to a percent, by multiplying by 100. You should get 114/465 = 0.245 then x 100 = 24.5% decrease.
Answer: Undefined
Step-by-step explanation:
The slope of the line is undefined because the slope of the line is the change in y over the change in x. The change in x is 0 but the change in y is a number. Any number divided by 0 must be undefined.

Answer:
13 costumes
Step-by-step explanation:
The amount of fabric used is the product of the amount per costume and the number of costumes.
A = na . . . . . A = total area; n = number of costumes; 'a' = area per costume
46 2/3 = n(3 1/2)
n = (46 2/3)/(3 1/2) = (140/3)/(7/2) = (140/3)(2/7) = 40/3 = 13 1/3
Apparently there is some waste, as Emerson used more fabric than necessary to make 13 costumes.
Surface area = area of 2 triangular sides + area of the roof + area of the base.
= 2 * 1/2 * 6 * 4 + 2 * 5*7 + 6 * 7
= 24 + 70 + 42
= 136 units^2
75%. Just divide 15/20 and you will get .75 then multiply by 100 to turn the decimal to a percent
