Answer:
there are 40% black ball a
white ball we don't know
so, we let = x
40\100 × x
now we cutting
ans is 10x
You can solve this system of the equations with graphical method or algebra method.
I solve this system with Gaus algorithm
first we divide second equation with number 3 and get x+10y=12
Than subtract first equation from second and get 5y=6 => y=6/5
now we replace y in the first equation and get x+5*(6/5)=6 =>x+6=6
=> x=0 (x,y)=(0,6/5)
Conclusion is that we have one intersection point between this two graphs.
Good luck!!!
Answer:
80 minutes.
Step-by-step explanation:
If you look at the graph, every 50 square feet, the time goes up 20 mins.So if 150 were to become 200, then 60 would become 80.
The percent of commission is 7.3% to the nearest tenth of a percent
Step-by-step explanation:
The given is:
- Bill earns a commission on every sale he makes
- He sells a bed for $591 and earns a $43 commission
We need to find the percent commission
To find the percent of commission divide the commission by the selling price and multiply the answer by 100%
∵ His commission is $43
∵ The selling price is $591
∵ The percent of commission = × 100%
∴ The percent of commission = × 100%
∴ The percent of commission = 7.2758%
- Rounded it to the nearest tenth percent
∴ The percent of commission = 7.3%
The percent of commission is 7.3% to the nearest tenth of a percent
