Answer:
See below.
Step-by-step explanation:
To calculate a percentage divide by the part by the whole, You will get a decimal. The decimal becomes a percentage after you multiply by 100. This moves the decimal place two places to the right. So 0.10 becomes 10%.
1. 20 is 50% of 40 since 20/40 = 0.5
2. 8/ 32 = 0.25 so it is 25%
3. 2/40 = 1/20 = 0.05 so it is 5%
4. 100/25 = 4 so it is 400%
5. 3/ 2 = 1.5 so 150%
To find a percentage of a number, multiply the number by the decimal conversion of the percent.
6. 0.15(300) = 45
7. 33/75 = 0.44 so it is 44%
8. 12/18 = 2/3 = 0.66 so it is 66%
9. 0.35(1000) = 350
10. 40 is 20% of what can be solved by remembering that 20* 5 = 100%. So 5*40 = 200. The number is 200.
Hi!
We know that a radius is a line that reaches from point A (the middle of a circle) to point B (the outer part of the circle).
Based on that information, the sentence that describes the radius the best is It is a segment from a point on the circle to the center of the circle.
Hope this helps! :)
