Answer:
3 : 7
Step-by-step explanation:
Let the radii be 3x, 7x.
Circumference = 2πr, where r = radius
Thus, ratio of circumference:
2 × π × 3x : 2 × π × 7x
= 3 : 7
( as 2, π and x get cancelled out)
Find the probability of Red/small.
Red = large + small
large = 8
Small = 12
Plug in 8 for large, and 12 for small
Red = 8 + 12
Red = 20
Now we know that the total red = 20
Do the same with small
3 small blue
12 small red
Small = blue + red
Small = 3 + 12
Small = 15
Note that red is first then small. Put red over small
Remember that red = 20, small = 15
20/15 is the fraction you need.
However, note that it says "reduce your answer" at the bottom
Divide 5 from numerator and denominator
(20/15)/(5/5) = 4/3
4/3 is your answer

a) The equation of axis is the middle y-coordinate, which is y = -1.5.
b) The period is the amount of time it takes for the graph to repeat, which is 6.
c) The amplitude is the vertical distance from an extreme point to the midpoint, which is 3.
d) This is a cosine graph since when x=0, y is not equal to 0.
For question 9 - It is stating that AE is equal to 38. So the length of the entire line is 38. We then need to look at which figures are actually useful to us, which in this case is AC which is 10. Therefore the answer is as simple as 38-10, which gives us an answer of 28 for the other half of the line, notated as CE.
Answer:
I believe the answer is cutting through open fields
Step-by-step explanation:
If you needed to get somewhere but you didn't have a direct path to where you needed to go; as in needing to make turns, then you should be able to get there faster if you go at a diagonal angle to the point in which you are trying to reach.
