Answers
Answer 1
Answer:
To find the perimeter you would need to add 35+35+65+65=200. If the perimeter is 200, and he circles around it 4 times, 200*4=800, which is the answer. Answer: The total amount of yards that Chris dribbles the ball is 800 yards.
a teacher asked 3 pupils to choose any 2 digit number square it and then find the remainder after dividing the result by 7. Doris got 6 Marie got 4, Horace got 3. Two of the pupils made a mistake. Why?
Answers
First write out all the two digit square numbers
4² = 16 5² = 25 6² = 36 7² = 49 8² = 64 9² = 81
Next divide all of them by 7
16/7 = 2 2/7 or 2 and 2 remainders 25/7 = 3 4/7 or 3 and 4 remainders 36/7 = 5 1/7 or 5 and 1 remainder 49/7 = 7 64/7 = 9 1/7 or 9 and 1 remainder 81/7 = 11 4/7 or 11 and 4 remainders
This tells us that the only possible remainders for a two digit square number divided by 7 are 1, 2 and 4 If Doris got 6 and Horace got 3, they must have made a mistake.

The following chips are placed in a bucket: 5 red, 3 yellow, 4 blue, and 1 green. One chip is randomly selected from the bucket. How often will a blue chip be selected?4 out of 13 4 out of 8 1 out of 13 4 out of 9
Answers
So,
If we add them together, we get 5 + 3 + 4 + 1 = 13
Since there are 4 blue chips, the probability would be 4 out of the total number of chips, or 4/13.
4 out of 13 because 13-9=4 so thats what i think
