TiliK225 [7]
Answer: Corries’ answer is correct.

1. Take the ratio, and add the parts to make a whole number —> 2:3 —> 2 + 3 = 5
2. Divide the total by 5 —> 30/5 = 6, meaning each part of the ratio is represented by 6 ounces
3. 2 * 6 = 12 and 3 * 6 = 18, meaning 12 ounces of blue paint and 18 ounces of yellow paint were used to make this green
4. Then, divide 12 by 30 and simplify to find out which student is correct
5. 40% of the paint in the container is blue paint, find the fraction equivalent to 40% which is 2/5

I need help ASAP can someone please help me right away​.​
PSYCHO15rus [73]

Answer:

60 degrees.

Step-by-step explanation:

We know that we can rotate the image by a total of 360 degrees until we reach the original point again.

To rotate the image to a point where the image looks the same, we need to take a look at how we can do this. We want to line up the image with the gap between the two white semicircles. There are a total of 6 of these gaps:

360/6 = 60 degree rotations will make the image the same.

I hope this helps!
