Thanks tianzhu,


I replicated it my child’s worksheet. I ask the teacher for anwers. Anyway, thanks alot…

Thank tianzhu,


For Q1 you are right, find only the pattern 8. Not sum up from 1st pattern to 8th pattern.

The question is correct. What I think is that use 2350 sticks to make which pattern no. left over sticks are ok.

Try 10 --------- 10/2(10+45) -------------- 275
Try 20 ---------------------------------------- 1050
Try 30 --------- 30/2(10+145) -------------- 2325, so the answer is pattern 30.

Is the above uses AP formular?

Thanks

Hi,


Thanks. For your input. But the answers are wrong. The correct anwers are 180 sticks for the first question. pattern 30 on the 2nd question.

for 1st question, i did it one by one:
pattern: 1 2 3 4 5 6 7 8
Sticks: 5 10 15 20 25 30 35 40
Total sticks = 5+10+15+20+25+30+35+40 = 180 sticks.

for Q2: I knew it is pattern 30. I found it from the web. But it did not show out it got it.

Please help. Thanks...

Hi,

I am crazy about my daughter math. Very difficult to solve. Please help :?:

Q: How many sticks does she need for the eighth pattern? If Doreen uses 2350 sticks, which pattern number will she form?

pattern 1= 5 sticks
pattern 2= 10 sticks
pattern 3= 15 sticks.

sorry, i cannot show the patterns. It was squeeze up

Thanks alot...

Daddy,...
