Yes 2/5 and 4/10 are equivalent fractions. This is because you are able to multiple both numbers in 2/5 by 2 and get 4/10. In addition, you can divide both numbers in 4/10 by 2, therefore they’re equivalent.
It's (A) 18 because if you add 46 & 26 it's 72 and then for you to get 18 , 72 + 18 = 90
I don't even know good sir, But it is most likely A
Since water piper is a cylinder shape, the equation to calculate the volume of a cylinder is:
Volume = radius* radius * 3.14 * height
volume = 5 * 5 * 3.14 * 7
Volume = 25 * 3.14 * 7
Volume = 25 * 21.98
Volume = 549.5
The volume of water take to fill the pipe is 549.5 cubic centimeter.
