Answer:
7 inches
Step-by-step explanation:
Using Pythagoras' theorem on the right triangle, that is
r² + 11² = 13²
r² + 121 = 169 ( subtract 121 from both sides )
r² = 48 ( take the square root of both sides )
r = 
≈ 7 in ( to the nearest inch )
Answer:
it's 300
Step-by-step explanation:
because 20 plus 150 plus 100 = 300
One of the approaches:
Each couple can send only one "representative" to the committee. Let's see in how many ways we can choose 3 couples (as there should be 3 members) out of 4 to send only one "representatives" to the committee: 4C3=4.
But each of these 3 couples can send two persons (husband or wife): 2*2*2=2^3=8.
Total # of ways: 4C3*2^3=32.

B is the answer due to when finding the solution you have to equalize the problems and solve.
144 ÷ 36 = 4
to solve a problem like this, flip it to a division problem
