B. 3/16
C. 5/16
D. 7/16

Answers

d. 7/16
i think its that because 4 plus 3 equals 7 and they asked second or third row and they only have second row up there and they asked for both so i think 7/16.
The answer is D.7/16 due to the fact that there are 4 students in the second row, and 3 students in the third, the ratio would be 7/16.hope i helped.

How do you find the answers

9. to find angle 6 just do 180-95 because a straight line is 180 degrees
To find angle 1 you just have to know that angle 5 is the same as angle one and to find angle five its the same as 95 degrees because they are across from each other ( they're called vertical angles ). From there I think you can figure it out. :)

Misha has a board that is 17 1/2 inches long that he has to into 3 equal pieces.How long should each piece be?

Answers

3 is written as 3/1 so:
(17 1/2)/(3/1)
(34/2)/(3/1)
34/2*1/3
34/6
17/3
5 2/3 inches.

Hope this helps :)

17.5 (Or 1/2) divided by 3 = 5.833333333, or just 5.8. So each piece would be 5 4/5 in long.

Sorry if it's a little confusing. Hope it helped! :)

How can you use models to explain why 3.1=3.10?

Answers

Answer:

3.1 = 3.10 because adding zero (0) in decimal number at the right most side doesn't affect the number as the same way adding zero at the left most side of a number doesn't affect the number.

Also, 3 and 1 ones are the same as 3 and 10 tenths.

Adding a zero would not do anything after a decimal because 1 is the tenth, and adding a zero will still make it 3 wholes and 1 tenth....0 hundredths. 

That is why 3.1 = 3.10
