By giving just the radius and asking for the arc length of that circle your answer will be without math is 22

Let’s do same math!
Arc length = (()/360)⋅2⋅⋅

Answer:
345 miles
Step-by-step explanation:
So we know that 2 cities are 5.75 inches apart on the map and the scale reads for every 0.5 inch its 30 miles. So we can first start of by diving 5.75 by 0.5, since we need to know how many “0.5” inches are in 5.75 inches. You’d get 11.5. Now 11.5 multiply that by 30 which would get you 345 miles.
Answer: A
Step-by-step explanation: I think its A because < means less than. So y is less than z. I hope that helps.
Step 1: set up equation
-2x+y=3
Step 2: add 2x to both sides
-2x+y=3
+2x +2x
<u>
y=3+2x</u>
Hope this helps :)
Ratio of girls to boys is (1/3*X) / (2/3*X).
That is, 1:2
Similarly, ratio of boys to girls is (2/3*X) / (1/3*X).
That is, 2:1
Step-by-step explanation:
- Assume, total Number of students in the class is X. Since, 1/3 part of the class is girls, this makes 2/3 part of the class boys.
- Total number of girls will be equal to 1/3 *X. Total number of boys is equal to 2/3*X.
- So, ratio of girls to boys is (1/3*X) / (2/3*X).
That is, 1:2. Similarly, ratio of boys to girls is (2/3*X) / (1/3*X). That is, 2:1
