Step-by-step explanation:
Discriminant = 16k² - 4(2)(-5k)
Since 16k² + 40k < 0, 2k² + 5k < 0, k(2k + 5) < 0.
Therefore -5/2 < k < 0.
Answer:
14 packs per hour
Step-by-step explanation:
The store sold 57 - 15 = 42 packs of toilet paper in 3 hours.
42 packs in 3 hours = 42/3 = 14 packs per hour
Answer:
50% percent chance the ball will be yellow
Step-by-step explanation:
Find the amount of all the balls-24 and the amount of yellow balls-12
Then divide the number of yellow balls by the number of total balls.
12÷24=0.5
0.5=50%
Answer: The mixed number 5 & 1/2
====================================
Work Shown:
1 & 1/2 = 1 + 1/2 = 2/2 + 1/2 = 3/2
3 & 2/3 = 3 + 2/3 = 9/3 + 2/3 = 11/3
------
Multiplying 1&1/2 with 3&2/3 is the same as multiplying 3/2 and 11/3
(3/2)*(11/3) = (3*11)/(2*3) = 11/2
-------
Use long division to find that 11/2 = 5 & 1/2
Or you can break it up like this
11/2 = (10+1)/2 = 10/2 + 1/2 = 5 + 1/2 = 5 & 1/2
