D^2 - 4d = 3d
d^2 - 7d = 0
d(d - 7) = 0
d = 0 or d - 7 = 0
d = 0 or d = 7
Answer:
450 minutes
Step-by-step explanation:
Given
w = 45000 - 100t
Required
Determine how long it'll take to empty the pool
Being empty means there's no water in the pool.
So, we have to set w to 0 to get the value of t
i.e w = 0
Substitute 0 for w in w = 45000 - 100t
0 = 45000 - 100t
Collect Like Terms
100t = 45000
Divide through by 100.
t = 450
Hence, it'll take 450 minutes to empty the pool
If you ate a third of the box and there ARE 16 left then you started with 48 originally
Answer:
y2-y1/x2-x1 or rise/run
Step-by-step explanation:
I learned this in algebra
12. Since there is no table given I will assume that what you want me to do is to show that Unit rate of Brandon’s biking.
SO here are the data that we need:
=> 8 and ½ miles = 8.5 miles
=> ½ hour = .5 hours or 30 minutes
Now, let’s solve for the unit rate
=> SO in every 30 minutes he bikes around 8.5 miles
=> Since 1 hour is equals to 30 minutes, simply multiply 8.5 by 2
=> 8.5 * 2 = 17miles
=> 17 miles / hour
