Answer:
25 feet
Step-by-step explanation:
Basically that non-regulation tennis court is a rectangle. You want to know the length of the diagonal. If you draw it on paper, you'll see that this then become 2 triangles... of which you have 2 sides, and are seeking the hypotenuse. So....
H² = A² + B²
H² = 20² + 15² = 400 + 225 = 625
H = 25 feet.
No. 26,341 is not evenly divisible by 3 .
Here's the trick you can use to decide this
just by looking at a big number:
==> If a number is divisible by 3, then the
sum of its digits is divisible by 3.
I've never taken the trouble to figure out why this works,
but it does work. I didn't make it up. It's widely known.
So let's look at 26,341 .
The sum of the digits is (2 + 6 + 3 + 4 + 1) = 16 .
16 is not divisible by 3 , so 26,341 is not divisible by 3 .
