Stephen's heart beats 68 times in one minute
Step-by-step explanation:
60 sec (one min) divided by 15 sec ( the unit of time we use to track the 17 heartbeats) = 4
4 times 17 =68
Answer:
8 vertices, 6 faces, 12 edges
Step-by-step explanation:
There doesn't seem to be a question, but based on the topic above the question I would say, find the irrational numbers
Answer:
the answer is two
Step-by-step explanation:
i don't have one but i did the quiz and got it right
<span>n + (n + 1) + (n + 2) = 36
Let's first create the equation ourselves and then see if it fits any of the available options. We want 3 consecutive integers that add up to 36. Let's use the value "n" to represent the first number in the sequence.
n
Now the next number will be n+1 and the third will be n+2. And since we want the sum, we get
n + n + 1 + n + 2 = ?
And finally, we want the sum to be 36, so our final equation is
n + n + 1 + n + 2 = 36
With this equation in mind, let's look at the available choices.
n + (n + 2) + (n + 4) = 36
Well, it has the 36 OK, but it has +2 and +4 where we have +1 and +2. So it won't fit and it's wrong.
n + (n + 1) + (n + 3) = 36
Closer. Got the 36 and the +1. But it has +3 instead of +2, so not a fit either.
n + (n + 1) + (n + 2) = 36
This looks good. Has a couple of extra parenthesis, but they don't affect the final answer and it has the +1, +2 and the 36. This one is correct.
n + (n â’ 1) + (n â’ 3) = 36
Hmm. The n - 1 has a possibility. Perhaps they want n to be the middle of the 3 numbers to add. If that's the case, then the other number should be n+1 which it isn't. Maybe they want the n to be the last number. If that's the case, then the third number should be n-2. But that doesn't work either. So this equation won't work.
So of the 4 choices, the only answer that works is "n + (n + 1) + (n + 2) = 36"</span>
