A triangle has one side that is 6 units long and another side that is 3 units long.
kiruha [24]

The possible value of the third length is an illustration of Triangle inequality theorem

The possible third lengths are 4 units and 6 units

<h3>How to determine the possible length of the third side?</h3>

To determine the third length, we make use of the following Triangle inequality theorem.

a + b > c

Let the third side be x.

So, we have:

x + 6 > 3

x + 3 > 6

3 + 6 > x

Solve the inequalities

x > -3

x > 3

x < 9

Remove the negative inequality value.

So, we have:

x > 3 or x < 9

Rewrite as:

3 < x or x < 9

Combine the inequality

3 < x < 9

This means that the possible value of the third length is between 3 and 9 (exclusive)

Hence, the possible third lengths are 4 units and 6 units

WILL GIVE BRAINLIEST<br><br>solve for x : -4 = (2/3)x <br><br>show steps please
cupoosta [38]
<h2>Answer:  x = -6</h2>

<h3>Step-by-step explanation:</h3>

To solve for x, we have to find a way to make x the subject of the equation (get x on one side and everything else on the other side)

<h3></h3>

since    -4 = (2/3)x     [mutiply both sides by 3]

⇒    -4 × 3 = 2x     [divide both sides by 2]

⇒   (-12/2) = x      [simplify by dividing -12 by 2]

∴            x = -6

Three workers have to do a certain job. The first worker can finish the job in 8 hours. The second worker can finish the job in
mestny [16]

Working together three workers would take 1 hour 36 minutes to finish the job

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

Given that first worker can finish the job in 8 hours

So in one hour, first worker can do \frac{1}{8} th of the work

The second worker can finish the job in 4 hours

So in one hour, second worker can do \frac{1}{4} th of the work

The third worker can also finish the job in 4 hours

So in one hour, third worker can do \frac{1}{4} th of the work

<em><u>The three workers working together in 1 hour can do:</u></em>

\frac{1}{8} + \frac{1}{4} + \frac{1}{4} = \frac{1 + 2 + 2}{8} = \frac{5}{8}

The three worker can thus do \frac{5}{8} th of the work in one hour

Hence the three of them together can finish the work in \frac{8}{5} hours

\frac{8}{5} = 1\frac{3}{5} hours

Thus working together three workers would take 1 hour 36 minutes to finish the job

Which type of transformation maps trapezoid PQRS onto trapezoid P'Q'R'S'? reflection rotation translation dilation
Keith_Richards [23]

Answer:

Dilation.

Step-by-step explanation:

From the given picture , it can be seen that the size of trapezoid P'Q'R'S' is decreased from trapezoid PQRS .

Reflection , rotation and translation are rigid motions that produces congruent images and do not change the size of the shapes.

But dilation is not a rigid motion because it changes the size of the shape by using a scale factor.

Hence, the transformation maps trapezoid PQRS onto trapezoid P'Q'R'S' is "Dilation".
