Answer:
3 is the correct answer (see explanations for each possible choice)
Step-by-step explanation:
1 cannot be right because 3 times smaller than 9 would be 3 as 1/3*9=3
2 cannot be right because 3 less than 9 is 9-3=6
3 is right because 3 times as much as 9 is 9*3=27
4 cannot be right because 3 more than 9 is 3+9=12
I think it might be c. but im not sure
Answer: 89.1
Step-by-step explanation: Firstly, for the square, you would multiply 8 by 8 which would result in 64. That is your first addend. Next, to find the area of the semicircle, you find the area of a whole circle, then divide by two. In this case, the area formula would be (pi)r^2. So, the radius would be 4, and in he formula that would end up with the answer being 50.24. Then, you divide by two. 25.1 (rounded to tenths) + 64 = 89.1.
Hope this helped!!
Answer:
6
Step-by-step explanation:
We need to find the slope
We have 2 points
(0,0) and (1,6)
m = (y2-y1)/(x2-x1)
= (6-0)/(1-0)
= 6/1
= 6
y = 6x
The constant of proportionality is 6
