the answer is 0 i used a calculator
Answer:
40 persons
Step-by-step explanation:
Data provided :
The power put out by a single person = 100 W
Power required by an electric clothes dryer = 4.00 kW = 4000 W
Thus,
The number of persons required to produce 4000 W of power
= ( Power required ) / ( power produced per person )
or
= (4000 W) / (100 W/ person)
or
= 40 persons
Hence, the number of persons required is 40

Step-by-step explanation:
<u>Step 1: Define</u>
Ax + bx = c
<u>Step 1: Solve for </u><em><u>x</u></em>
- Factor: x(A + b) = c
- Isolate <em>x</em>: x = c/(A + b)
We know that we cannot divide by 0, so A + b cannot equal 0.
Answer:
1. a ≥ -3 and a ≤ 3
I am assuming you mean to have an = sign as well
Step-by-step explanation:
|a| < =3
we get two solutions, one positive and one negative
remember to flip the inequality for the negative
a<=3 and a >= -3
