Answer:

13.9

Step-by-step explanation:

Use Pythagorean Theorem:

Both of the lengths given are the legs,

13.5^2 + 3.2^2 = c^2

182.25 + 10.24 = c^2

192.49 = c^2

13.87 = c

-4 + 3y = -43<br> what does y equal?

NeTakaya

Answer:

-13

Step-by-step explanation:

We remove the -4 by adding 4 to each side:

3y = -43 + 4

Now we simplify to give:

3y = -39

So now we divide both sides by 3 to give our answer of:

y = -39/3
y = -13
We can substitute this into the original equation to check our answer:

-4 + 3(-13) = -43

-4 + -39 = -43

A circle with the diameter of 20 mm is showing what is the exact Sir conference obvious and then question to what is the approxi

yaroslaw [1]

Answer:

The approximate circumference is 62.8 mm

Step-by-step explanation:

Circumference is basically the perimeter of the circle

Circumference is given by

$2 *\pi *r$

Here the diameter is 20 mm, so the radius will be half of diameter = 10 mm

Substituting the given values, in above equation, we get -

Circumference =

$2 *3.14 * 10 \\62.8$ mm

The approximate circumference is 62.8 mm
