If we have 300 animals total, and the ratio of cats to all animals is 7 : 15 or 7/15, we can multiply that fraction/ratio by the total, so 300 * 7 /15 = 20 * 7 = 140.
The area equation for a rectangle is length times width. And the area equation for a half (or semi) circle is (1/2) times pi (or 3.14) times the radius squared.
So, you have to add the area of the rectangle and semi-circle together.
Rectangle: A = 18*10 = 180 cm^2
Semi-circle: A = (1/2)*3.14*(18/2)^2 = 127.17 cm^2
Add those together to get 307.17cm^2 or choice C.
Hello!
To find the circumference of a circle, you multiply by diameter by pi. As we have our diameter, let's just multiply by pi!
8
≈25.13
Therefore, our circumference is about 25.13 feet
I hope this helps!
The answer is Candy Bar to Nachos represents a ratio of 2:1. A ratio means that when you have 1 of something times it buy the other number. You have 1 Nacho to every 2 Candy bars. You can also fine this by reducing. 30:15 can both be divided by 15 making it 2:1. You're welcome :)!
