Answer:
The total earning of commission on sales of 85, 000 will be:
Step-by-step explanation:
- Total sales earning = 85,000
As salesperson earns 5% commission the first 70,000.
As the salesperson earns 7% commission on the sales over 70,000.
As 15000 is the sales earning on which he will get commission 7%.
Because
So the 7% earning of salesperson will on 15000 will be:
Therefore, the total earning of commission on sales of 85, 000 will be:

Answer:
<h2>
0.0526ft/min</h2>
Step-by-step explanation:
Since the gravel being dumped is in the shape of a cone, we will use the formula for calculating the volume of a cone.
Volume of a cone V = πr²h/3
<em>If the diameter and the height are equal, then r = h</em>
V = πh²h/3
V = πh³/3
If the gravel is being dumped from a conveyor belt at a rate of 20 ft³/min, then dV/dt = 20ft³/min
Using chain rule to get the expression for dV/dt;
dV/dt = dV/dh * dh/dt
From the formula above, dV/dh = 3πh²/3
dV/dh = πh²
dV/dt = πh²dh/dt
20 = πh²dh/dt
To calculate how fast the height of the pile is increasing when the pile is 11 ft high, we will substitute h = 11 into the resulting expression and solve for dh/dt.
20 = π(11)²dh/dt
20 = 121πdh/dt
dh/dt = 20/121π
dh/dt = 20/380.133
dh/dt = 0.0526ft/min
This means that the height of the pile is increasing at 0.0526ft/min
Answer:
x= 4/3
Step-by-step explanation:
Subtract 3/7 from both sides
-x= 2x-28/7
simplify
-x=2x-4
Subtract 2x from both sides
-3x=4
divide both sides by -3
x= 4/3
