A furniture shop refinishes chairs. Employees use one of two methods to refinish each chair. Method I takes 0.5 hours and the ma
satela [25.4K]

Answer:

method I = 88 chairs

method II = 62 chairs

Explanation:

This problem can be modeled by a system of two linear equations.

Define x as the number of chairs refinished by method I and y by method II

The sum of hours spent on both methods should equal 199 and the sum of total material cost should equal $1226, therefore:

0.5x + 2.5y = 199

9x+7y = 1226

Multiplying the first equation by -18 and adding it to the second equation we can solve for the value of y:

9x+7y +(-9x - 45)= 1226+(-3582)\\y=\frac{2356}{38} = 62\\

We can now apply the value of y found to the first equation and solve for x:

0.5x+2.5*62 = 199\\x=\frac{199 - (2.5*62)}{0.5} = 88

Therefore, they should refinish 88 chairs with method I and 62 chairs with method II

A 9-volt battery is connected to a capacitor that stores 4.5 × 10–3 joules of energy. Calculate the amount of charge on the capa
zalisa [80]

Amount of charge on the capacitor=q=10⁻³C

Energy stored=4.5x10⁻³ J

potential difference= 9 V

Energy stored= E= 1/2 q V

4.5x10⁻³ =1/2 q (9)

q=10⁻³C

Thus the amount of charge on the capacitor=q=10⁻³C

A bike at rest moves to 2 m/s in 2 seconds.
Sergio039 [100]

Answer:

Explanation:

When at rest, initial velocity = 0

In 2 seconds, final velocity = 2 m/s

Acceleration = (final velocity - initial velocity) / time

= (2 - 0) / 2

= 1 m/s^2
