Answer:
It would take 7.62 minutes for the third conveyor belt alone to do the same job
Step-by-step explanation:
The together rate is the sum of each separate rate.
In this question:
First conveyor: Rate of 1/9.
Second: Rate of 1/11.
Third: Rate of 1/x.
Total: 1/3
So








It would take 7.62 minutes for the third conveyor belt alone to do the same job
For the first one, it's (a^8b^6). For the second one, it's 81m^8n^20.
First, let's divide by 4, since 4 can go into both the numerator and denominator.
56/4 = 14
100/4 = 25
That gives us 14/25.
That fraction can't be reduced further, so the simplest form of 56/100 is 14/25.
Hope that helped!
Step-by-step explanation:
4-17x^2+16=0 s
Calculate multiply
20-17x^2=0
Reoder the term
-17x^2+20=0
Calculate the discriminat
D=0^2-4x(-17)x20
Simplify
D=1360
The quadric equation has 2 real solutions
So your Solution is :
2 real solutions
