Answer:

12.8 IN.

Step-by-step explanation:

So, what exactly is perimeter?

Perimeter= 2L+ 2W

In this question we were given the length.ie.Base and the perimeter itself.

●Length is 39 In.

●Perimeter is 103.6 In.

●We don't know the width.

But, as per given the question, we know that;

1 length = 39 In.

2 lengths= 78 In.

Now that we know the <u>total</u><u> </u><u>length</u><u> </u><u>we</u><u> </u><u>can</u><u> </u><u>find</u><u> </u><u>the</u><u> </u><u>total</u><u> </u><u>width</u><u>.</u>

See as follows,

103.6 - 78= 25.6

<u>2</u><u> </u><u>widths</u><u>=</u><u> </u><u>25</u><u>.</u><u>6</u>

<u>1</u><u> </u><u>width</u><u>=</u><u> </u><u>25</u><u>.</u><u>6</u><u>÷</u><u>2</u>

<u>=</u><u>12</u><u>.</u><u>8</u><u> </u><u>In</u>

Solve for k.<br> (k)4+ 3= 14<br> ​k=<br> ​
r-ruslan [8.4K]
Solving for "K" , got it! :)
I'll make it easier to solve

(k)4+3-14=?
? = 0

4(k)-11 = 0 

Take off the '0' and the addition symbol so we can add from 11 on your sides

4(k) - 11
+11   +11
---- ----
15k. 22
      ⬆ This would be your answer for k            

 4(k) = 11
÷4 ÷4
--- ----
1K ?

K = 11/4 (for fraction)
K = 2.75 (as a decimal)

What is the length of the unknown leg in the right triangle? 6 mm 8 mm mm mm
makkiz [27]

Answer: 10mm

Step-by-step explanation: You are going to use the "Pythagorean Theorem" method.

Step 1 :

Equation : a^2+b^2=c^2

plug in your data to the equation given. Then simplify and add.

6^2+8^2=C^2

simplify : 36 + 64 = C^2

simplify : 100 = C^2

Step 2 :

Find what goes into 100 evenly.

100 = 10^2 = (10)(10) = C^2

Step 3:

Find the square root of 10^2 = C^2

10 = c

Last Step :

The length of the unknown leg in the right triangle is 10mm

YAY!!!! you're finished! I hope I explained this so it was easy for you to understand.

DaniilM [7]

Answer:Here are some more problems to solve.

Calculate the volume of a paperback book with the following dimensions:

Length = 12 cm

Width = 3 cm

Height = 20 cm

Calculate the volume of a steel bar with the following dimensions:

Length = 5 cm

Width = 2 cm

Height = 30 cm

Now determine the density of the steel bar if its mass is 2.34 kg. (Hint: Convert to grams first.)

A cork has a volume of 5.0 cm3 and a mass of 1.2 grams. Calculate its density.

Water has a density of 1 g/cm3. If you placed a cork and a steel paper clip in a jar of water, what do you think would happen? Use your knowledge of density to explain the outcome.
