Answer:

The local newspaper has 250 readers in total

Step-by-step explanation:

Given that

Letter to the editor = 10

Also it is given that 10 is the 4% of total readers of the newspaper.

Let x be the number of readers of the newspaper

It can be written as:

10 = 4\%\ of\ x

Converting the percentage into decimal

10 = 0.04x\\\frac{10}{0.04} = \frac{0.04x}{0.04}\\x = 250

The newspaper has 250 readers.

Hence,

The local newspaper has 250 readers in total

Please help me !!! i will mark brain-list for the correct answer !!!

Answer:

B

Step-by-step explanation:

So remember that a quarter of a circle is 90 degrees, a half of a circle is 180 degrees, and a whole circle is 360 degrees.

Looking at the image shown, it must be half a circle, whihc is 180 degrees. The image tells us that the 1st angle is 7 degrees. Now, we must find the 2nd angle.

Heres what we know however:

angle 1 + angle 2 = 180 degrees.

How do we know this?

Well, there are only 2 angles in this 180 degrees. We know that the first one is 7 degrees.

Lets input that into our nice lil equation to get an answer:

7 degrees+angle 2 = 180 degrees

Now lets solve.

Subtract 7 on both sides, and your left with:

angle 2 = 173 degrees.

So the answer must be:

<u>173 degrees</u>

Hope this helps! ;)
