First, we need to find his unit rate, the amount he earns in 1 hour.

So, we have to divide 28.50 by 2.

That is:

28.50 / 2 = $14.25 per hour

To find the amount he earns in 8 hours, we will need to multiply hourly rate found by "8". So,

14.25 * 8 = $114

<h2>Rolando earns $114 in 8 hours</h2>

erica [24]

Hello!

The answer is:

Luke did a work of 308N.m or 308 Joules.

When a force is applied on a object making it to move covering a distance we call it "work". The movement caused by the force, will follow the same direction that the force.

We can calculate the work done by using the following equation:

$Work=Force*distance*Cos(\alpha)$

Where,

Work is the transferred energy.

Force, is the force applied to the object.

Distance, is the distance covered due to the applied force.

α, is the angle at the work is done.

We are given the following information to calculate the work done:

$Force=22N\\Distance=14m$

So, substituting the given information into the equation to calculate work, we have:

$Work=Force*distance\\Work=22N*14m=308N.m$

Hence, we have that Luke did a work of 308N.m or 308 Jouls.

Have a nice day!

The length of a room is 18

Virty [35]

<em><u>Question:</u></em>

The length of a room is 18 1 /2 feet. If using 1 /4 inch = 1 foot scale, what would be the length of a wall on a blueprint of a floor plan?

<em><u>Answer:</u></em>

The length of a wall on a blueprint of a floor plan is $4.625 \text{ or } 4\frac{5}{8} \text{ inches }$

<em><u>Solution:</u></em>

Given that,

$Length\ of\ room = 18\frac{1}{2} \text{ feet }\\\\Length\ of\ room = 18.5 \text{ feet }$

The scale given is:

$\frac{1}{4}\ inch = 1\ foot$

To find: Length of a wall on a blueprint of a floor plan

Let "x" be the length of a wall on a blueprint of a floor plan

Then from given,

$\frac{1}{4}\ inch = 1\ foot\\\\x\ inches = 18.5\ feet$

This forms a proportion and we can solve by cross multiplying

$\frac{1}{4} \times 18.5 = x \times 1\\\\x = 4.625\\\\In\ terms\ of\ mixed\ fraction,\\\\x = 4\frac{5}{8}$

Thus length of a wall on a blueprint of a floor plan is $4.625 \text{ or } 4\frac{5}{8} \text{ inches }$

What value must be defined for to remove the discontinuity of this function at ?

olchik [2.2K]

Answer:

Option D. 8

Step-by-step explanation:

we have

$f(x)=\frac{x^{2}-16 }{x-4}$

Remember that

$x^{2}-16 =(x+4)(x-4)$

substitute

$f(x)=\frac{(x+4)(x-4)}{x-4}$

Remove the discontinuity at x=4

Simplify

$f(x)=(x+4)$

Find the value of f(4)

For x=4

$f(4)=(4+4)=8$
