Answer:
r = 6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
PR² = PQ² + QR² , substitute values
(r + 4)² = r² + 8²
r² + 8r + 16 = r² + 64 ( subtract r² from both sides )
8r + 16 = 64 ( subtract 16 from both sides )
8r = 48 ( divide both sides by 8 )
r = 6
Answer:
5,7,3,2
Step-by-step explanation:
It's pretty simple: a prime number is a number that can *only* be divided by the number 1 and it's own.
I just checked all the numbers from 1 to 10 in order to solve this problem.
If you have any questions about the way I solved it, don't hesitate to ask!
Hello!
To solve this you have to find the ratio between the two cylinders
Cylinder 1 height is 30
Cylinder 2 height is 20
this is a 30:20 ratio
This can be reduced to a 3:2 ratio
Now you look for one that are also equal to 3:2
3 * 7 = 21
2 * 7 = 14
The answers are 3:2 and 21:14
Hope this helps!
