Alright so the first one involves in shading.
You can see that Jack and Renee have two bars with rectangles inside the bar.
Jack took 3/4 hours or in words, three out of four. So in Jack's bar, shade 3 boxes and leave one unshaded.
Renee took 2/3 or two out of three. Shade 2 boxes in Renee's bar and see the difference.
As you can see, Jack has more shade length than Renee and that could only mean one thing:
Jack took longer to fix the tire than Renee.
The symbol that represents this is 3/4 > 2/3
The second activity has the same case.
Water: 3/5 means that you have to shade three boxes and leave the other two unshaded.
Sports Drink: 4/6 means that you have to shade four boxes and leave the other two unshaded.
As you can see again, there is more sports drink than the water since the shade length is longer in the sports drink than on the water.
This meant that she poured in more sports drink than water.
The third activity is just as simple, you just need to visually make up your own sections. Do the shading then see which one is bigger then just input the sign (hint: the first one is < and the second one is >)

Answer:
382.925 feets
Step-by-step explanation:
The solution diagram is attached below :
Converting radian measurement to degree :
radian angle * 180/π = degree angle
1.2 * 180/π = 68.755°
0.9 * 180/π = 51.566°
Height of dam is h:
Using trigonometry :
Tan θ = opposite / Adjacent
Tan 68.755° = h / x
h = x Tan 68.755° - - - (1)
Tan 51.566° = h / (155+x)
h = (155+x) tan 51.566° - - - (2)
Equate (1) and (2)
x Tan 68.755 = (155+x) Tan 51.566
x Tan 68.755 = 155tan 51.566 + x tan 51.566
x Tan 68.755 = 195.32311 + x Tan 51.566
x Tan 68.755 - x Tan 51.566 = 195.32311
x(tan 68.755 - tan 51.566) = 195.32311
x * 1.3120110 = 195.32311
1.3120110x = 195.32311
x = 195.32311 / 1.3120110
x = 148.87307
Using :
h = x Tan 68.755
h = 148.87307 * tan(68.755)
h = 382.92539
h = 382.925 feets

DO I HEAR 100 POINTS? Yes.
For the first image, that answer is A.
For the second image, I'm a bit confused on which problems you want me to do, so I'll do number 10, 11, and 14.
10) Yeah, you're correct, it is J.
11) (1,-6), (-2,-5), (8,2) (4,0) and I can't see the last point so..
14) Can't see the question :(
It was used to see how your basic math skills
