What is, 18 5/12+8 10/17+23 7/12+28 7/17

Answers

Answer 1

Answer:

18 5/12 + 8 10/17 + 23 7/12 + 28 7/17

First change them to improper fractions

18 5/12 = 221/12

8 10/17 = 146/17

23 7/12 = 283/12

28 7/17 = 483/17

now find the common denominator which would be 204

221/12 = 3757 /204

146/17 = 1752 /204

283/ 12 = 4811 /204

483/ 17 = 5796 /204

now add

(3757 + 1752 + 4811 + 5796) = 16,116/204

now divide

16,116 ÷ 204 = 79

Your answer is D. 79

Hope this helps. :)

Answers

V=LWH
SA=2(LW+LH+WH)
V=240
first check that they are 240 volume
multiply numbers they should equal 240

the first one (A) can be eliminated since the dimentions are the same and therefor the surface areas are the same

2nd one check so far

3rd one (C) 6*4*15=360 which is wrong so eliminate this one

4th (d) 12*6*5=360 which is not 240 so eliminate

answer is B

Is 2115 divisible by 9 if so explain why or why not

Answers

Yes It is because when you divide any number by another and it does not have a decimal it is divisible by that number and when you divide 2115 by 9 it comes out 235 (without a decimal) so it is divisible.
Hope that makes sense lol
Hope I helped :)

yes because if you divide 2115 by 9 you get 235
