Answer:
For B the answer is 1 : 30. For A the graph is Y goes up 2 for every 60 on the X.
Answer:
The Answer is J because 1 1/2 or 1.5 times itself equals 2 1/4 or 2.25
Answer:
a. yes
b. no
c. yes
d. yes
Step-by-step explanation:
For a, 27 + 38 can be broken apart. 27 is broken up by adding smaller numbers (20 + 7 = 27) and the same is done with 38 (30 + 8 = 38), so A and C shows a way to add 27 and 38. In C, the numbers are just put into a different order. B is not a way to add 27 and 38, because the sum is different.
27 + 38 = 65, however 20 + 70 + 38 = 128. The addition problem for D is a way to solve for 27 + 38, because it is broken up differently than A and C. They instead added the 20 and 30 together first, then split up 15 (from 8+7) into 10 and 5. So D is a way to solve, because it gets the same answer as 27 and 38 :D
Answer:
740 or 990
Step-by-step explanation:
It just depends on the height. I don't know if it is 10 or 15. If the height is 15 then 990. If the height is 10 then 740. :)
