Answer:b
Step-by-step explanation:
While this problem seems confusing, the answer is rather simple.
All you have to do is the reverse of what they are asking.
This is, substract 8 to 60 and then divide by 4:
So the interval which 13 falls into is 10 to 20 and the answer is b.
Answer:
4, 3, 4
Step-by-step explanation:
The unsimplified ratio of squares to triangles is 6:8, which simplifies to 3:4. That means, for every 3 squares, there are 4 triangles
As stated above, the simplified ratio of squares to triangles is 3:4
A) The equation for circumference is C=2piR. So Filling in for circle A we have 28.26=2*pi*4.5 so we want to isolate pi which I'm gonna call x for it's easier for me xD. So we're gonna start by dividing 4.5 from each side which is gonna leave us with 6.28=2*x which gives you x(pi)= 3.14. For circle B we have 15.70=2*x*2.5 isolate x by first dividing 2.5 which leaves us again with 6.28=2x and x= 3.14.
B) The equation for area is A=piR^2. So again for circle A we have 63.585=x9^2. This one is harder but also are you sure that the area is 63.585 it's supposed to be 254.469 (We'll come back to this)
C) The observation you can make about the value of pi for circles A and B is that it stays consistent at 3.14
Answer:forgot to add sin a = -5
