tatiyna
Lets answer this:-

1st lets divide to see how many times 28 goes in 8. And then we will multiply....

28 ÷ 8 = 3.5

Now lets multiply to see how many symphonies are equal to 25 concerts. Lets do it:-

3.5 × 6 = 21

So, 21 symphonies are equal to 28 concerts. 

Lets divide to see how many concerts are equal to 42 symphonies and the multiply to get our final answer. 

42 ÷ 6 = 7

7 × 8 = 56.

So, 56 concerts are equal to 42 symphonies.

Hope I helped ya!!

Can somebody help me with this plz?!?

Answer:

Step-by-step explanation:

The angle is 60 degrees and a whole circle has a total of 360 degrees, of that makes sense. So if you do 360/60, you get 6. This tells you that 6 of those particular arcs fit into this particular circle.

Find the circumference of the circle. You are given the radius, 3. Use the circumference formula, 2(pi)(r). You get 6pi.

6/6 = 1, so the length of that one arc is just p

Hope this helps!.
