Answer:
240
Step-by-step explanation:
So let the first side be x. So the next side is 3x and the last side is (3x +60) . Add all 3 sides and set equal to 480. So x + 3x + (3x +60)= 480. Now do the Algebra. So 7x + 60 = 480. Subtracting 60 we get 7x = 420 so x= 60. You are asked to ffg ind the length of the longest side so 3(60) + 60 = 240.
Answer:
2 hours, 26 minutes
Step-by-step explanation:
2 boxes of 21 parts = 42 total parts
3 minutes per part = 42 x 3 = 126 minutes
10 minutes per box to package = 10 x 2 = 20 minutes
126 + 20 = 146 minutes
2 hours = 120 minutes
146 - 120 = 26
Final Answer: 2 hours, 26 minutes
Answer:
x = 35/36
Step-by-step explanation:
3(x-1/4) = 13/6 Distribute
3x-3/4=13/6 Add 3/4 on both sides
3x = 35/12 Divide by 3 on both sides
x = 35/36
C) 50 randomly selected people leaving the movie teather
Answer:
40
Step-by-step explanation:
The number of gift baskets Nikki can make varies directly with the amount of time she spends making the baskets .
Let n be the number of baskets and let t be the mount of time it takes to make the basket. This means that:
n α t
=> n = kt
where k = constant of proportionality
She can make 4 baskets in every 1/2 hour.
This means that:
4 = k * 1/2
=> k = 4 * 2 = 8 baskets per hour
The time is now 5 hours (t = 5). Therefore:
n = 8 * 5 = 40 baskets
She can make 40 baskets in 5 hours.
