The movement of the ant illustrates the length of an arc

The measure of the central angle is 2.625 radians

<h3>How to determine the central angle</h3>

The radius of the arc is given as:

r = 8

The distance walked is given as:

L = 21

The length of an arc is

L = r\theta

So, we have:

21 = 8\theta

Divide both sides by 8

\theta = \frac{21}{8}

Divide

\theta = 2.625

Hence, the measure of the central angle is 2.625 radians

What is 4589215 rounded to the nearest thousand place
Musya8 [376]

The answer is 4589000.

And the reason, is:

The thousands place is the number 9, so you look at the number next to it on the right side, which is the number 2. Is 2 above 5, or over five? Its below five. So since its below five, the nine will stay as a nine but the rest of the numbers on the right side of the nine will become 0's. But if it was a 5 or above, the nine would become a 10. But you cant say 45810000, so you'd have to change the 8 to a 9.


Hope this helps :)

Two step inequalities intergers

.Two-step inequalities<span> are very easy to solve and the rules you have to adhere to are the same as for the one-step inequalities – remember that you need to change the sign of inequality when </span><span> multiplying or </span>dividing<span> the whole inequality with a negative number.

Ted has $3.90. He has only dimes and quarters. He has 27 coins altogether. How many of each does he have
mestny [16]

Answer: 8 quarters 19 dimes

Step-by-step explanation:

we already know 8+19=27, if 4 quarters equals a dollar then you use 4 quarters each to create 2 dollars.

then, use 10 dimes to create another dollar summing it up to $3. now all we have to do is make 90 cents, and we've already used 18 coins.

if we used another 9 dimes, that would equal 90 cents.

in conclusion, 4+4= 8

8+10= 18

18+9= 27, and having $3.90
