Help plz dont know the answer

Mathematics
1 answer:
stealth61 [152]3 years ago
6 0

Answer is B

How I got is because I had to first figure out what 40 seconds worth of heartbeats are equal to. 80 - 48 is 32 divided by 2 is 16. Next, I added 48 and 16 which got me 64. All I had to do next was to add 80 and 16 because the rate of heartbeats per 10 seconds is 16. 80+16=96 and thats how I figured that the answer is B

which three numbers make a right triangle the square root of 4 the square root of 5 the square root of 9 + square root of 6 the
statuscvo [17]
Please, group your sets of numbers, using {   }  notation or at least semicolons ( ; ).  Thanks.

Looking at what I think is your first set:   { sqrt(4), sqrt(5), sqrt(16) }

Square each of these and then subst. the results into the Pythagorean Theorem:

  { 4, 5, 16 }        Do 4 and 5 when added together result in 16?  NO.
Therefore,   { sqrt(4), sqrt(5), sqrt(16) }  does not produce a right triangle.

Your turn.  Pick out the next 3 numbers and test them using the Pyth. Thm.
