hello, im in 3rd grade and i need help on these 2 questions.
1) What is 3 as a percentage of 10?
2) The nth term rule for a sequence is 2n+3. Write the first 4 terms in this sequence.
is question 1 30%
thanks if you reply
#1 is indeed 30%
for #2, just substitute values 1,2,3,4 for n. The terms are seen to be
2*1+3=5
2*2+3=7
2*3+3=9
2*4+3=11
da mess you's in 3rd grade and getting that............. wow i privileged
Hello! I'd be happy to help you with your questions.
1) To find out what 3 is as a percentage of 10, we need to divide 3 by 10 and then multiply by 100. This is because a percentage is a way of expressing a number as a fraction of 100. So the calculation will look like this:
3 / 10 = 0.3
0.3 * 100 = 30
Therefore, 3 is 30% of 10, not 30%. I hope this clears things up!
2) The nth term rule for a sequence is given as 2n+3. To find the first 4 terms in the sequence, we substitute the value of n into the formula and calculate the corresponding terms.
When n = 1:
2(1) + 3 = 2 + 3 = 5
When n = 2:
2(2) + 3 = 4 + 3 = 7
When n = 3:
2(3) + 3 = 6 + 3 = 9
When n = 4:
2(4) + 3 = 8 + 3 = 11
So, the first 4 terms in this sequence are 5, 7, 9, and 11.
I hope this helps! Let me know if you have any more questions.
