If he wants to earn $1000, it means that $1000 must be 20% of his overall sales.
1000 = 20% * x
1000 = 20/100x
1000 = 0,2x / ÷ 0,2 (both sides)
x = 5000
Answer: A salesman must sell products for $5000 to earn $1000.
Answer:
2,143.57
Step-by-step explanation:
The equation for volume of a sphere is 4/3 x pie x r^3. Plug in 8 for r = 512. 512 x 3.14= 1,607.68. 4/3 x 1,607.68 is about 2,143.57
11/36 would be the probability of getting 4 , when two dice are thrown simultaneously.
As there are 6 faces of die,
So Probability of Not getting four in one dice = 
As both events are mutually exclusive, the probability of not getting four in two dice = 
So probability of getting at least one four is = 
So probability =

Let

be the amount of salt (in pounds) in the tank at time

. We're given that

.
The rate at which the amount of salt in the tank changes is given by the ODE






Given that

, we find that

so that the amount of salt in the tank is described by

The tank will be filled when

, or after

minutes. At this time, the amount of salt in the tank is
