Answer:

From left to right:

pentagon

quadrilateral

rhombus

parallelogram

Step-by-step explanation:

From left to right:

First polygon:

5 sides, pentagon. This pentagon has two sets of congruent sides, but there is no special name for it.

Second polygon:

4 sides, quadrilateral. This quadrilateral has 3 congruent sides, but there is no special name for it.

Third polygon:

4 sides, quadrilateral. All sides are congruent. It is a rhombus. A rhombus is also a parallelogram.

Fourth polygon:

4 sides, quadrilateral. There are two pairs of congruent sides. It is a parallelogram.

Before paying employee bonuses and state and federal taxes, a company earns profits of $60,000. The company pays employees a bon

wariber [46]

Answer:

$\left[\begin{array}{ccc}1&0.05&0.05\\0.05&1&0\\0.4&0.4&1\end{array}\right] *\left[\begin{array}{c} x_1\\x_2\\x_3\end{array}\right] = \left[\begin{array}{c} 3000\\3000\\24000\end{array}\right]$

Step-by-step explanation:

Given:

- Profits earned = $ 60, 000

- Bonus after tax = 5%

- State tax after bonus is = 5%

- Federal tax after bonus and state tax is = 40%

Find:

A linear equation system to find the amounts paid in bonuses, state tax, and federal tax.

Solution:

Define variables:

- x_1 : amount paid for bonuses

- x_2: amount paid for state tax

- x_3: amount paid for federal tax

- Since bonuses are paid after taxes at 5 %:

x_1 = 0.05(60,000 - x_2 - x_3)

3000 = x_1 + 0.5x_2 + 0.5x_3

- State taxes are paid after bonuses:

x_2 = 0.05*(60000 - x_1)

x_2 + 0.05x_2 = 3000

- Finally federal tax are paid:

x_3 = 0.4*(60,000 - x_1 - x_2)

x_3 + 0.4x_2 + 0.4x_3 = 24,000

- Therefore the system is:

x_1 + 0.5x_2 + 0.5x_3= 3000

x_2 + 0.05x_2 = 3000

x_3 + 0.4x_2 + 0.4x_3 = 24,000

Therefore the system can be expressed as an equation below:

$\left[\begin{array}{ccc}1&0.05&0.05\\0.05&1&0\\0.4&0.4&1\end{array}\right] *\left[\begin{array}{c} x_1\\x_2\\x_3\end{array}\right] = \left[\begin{array}{c} 3000\\3000\\24000\end{array}\right]$

The face of a clock has a circumference of 63 in. What is the area of the face of the clock?

ryzh [129]

Answer:

The area of the clock $= 315.41\ inch^{2}$

Step-by-step explanation:

We have been given the face of the clock that is $63\ in$

So that is also the circumference of the clock.

Since the clock is circular in shape.

So $2\pi(r)=63\ inch$

From here we will calculate the value of radius $(r)$ of the clock that is circular in shape.

Then $2\pi(r)=63\ inch =\frac{63}{2\pi} = 10.02\ in$

Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.

Now $\pi (r)^{2}=\pi(10.02)^{2}=315.41\ in^{2}$

So the area of the face of the clock = $315.41\ in^{2}$

Reduce -56/-70 to lowest terms.<br> 8/10 <br> -4/5 <br> -2/3 <br> 4/5

VLD [36.1K]

This one is just common sense - you don't even have to do any work. Since there's a negative on both the top and bottom you cancel them, which eliminates both the second and third answer choices. Also, 8/10 and 4/5 are the same, but 4/5 is simplified more so that is your answer.
