Answer:
(C)
Step-by-step explanation:
The diagram is divided ninto 5 parts that is rectangles ABCD, CHGD, GFEH and triangles CIH and DGJ.
Area of rectangle ABCD= 
=
Area rectangle CDHG=
=
Area rectangle HGFE=
=
Area of triangles CIH and DIG= 
=
Surface area of the triangular prism=Area of rectangle ABCD+Area rectangle CDHG+Area rectangle HGFE+Area of triangles CIH and DIG
=
Hence, option C is correct.
Answer:
The number of students in the school band = 70
40% of students in the school band are sixth graders.
20% of students in the school band are seventh graders.

I think the anwser is 17,887
Answer:
8
Step-by-step explanation:
Use substitution: substitute each number from the set in for x, and see if the result from dividing is 45.
4
360/x=45
360/4=90
90 ≠ 45
Therefore, 4 does not make the equation true
8
360/x=45
360/8=45
45=45
Therefore, 8 does make the equation true.
16
360/x=45
360/16=22.5
22.5 ≠ 45
Therefore, 16 does not make the equation true.
So, 8 is the value that makes the equation true
