The water level goes up .4 feet for every .5 hours according to the chart. This also means it goes up .8 feet every hour. Using this as our slope or rate of change, we find that in 0 hours the water level was 18.7-.8= 17.9 feet. This is the original water level. With this information, the equation we get is 0.8t+17.9=w(t).

Did you use coordinate geometry?

Yeah my reasoning sucks...

Wouldn't they be 0 meters apart.... The cable is 10 m above the gound and half the cable is 40 m long. SInce the cable is 10 m above the gound, that means that the cable is 40 m above the ground. If the length of half the cable is 40 m and the cable is 40 m above the ground, wouldn't the cable have to be folded in half? If the cable is folded in half, then the 2 poles are 0 meters apart.

Edit:

Since my previous answer is a total mess, I'll try to clarify.

The problem tells us that the bottom of the cable is 10 m above the gound. Since the poles holding up the cable are 50 m tall, that means that the top of the cable is 50 m above the ground. If we cut the cable in half, there are 40 m on the left and right side. Taking the right side only, the cable is 40 m long. Since the cable is 10 m above the gound, it is 40 m tall. This is the most confusing part that I can't explain well... In order for the cable to be the same length as it is tall, the cable must be right on the pole. For the cable to be on the pole, then the cable must have been folded exactly in half meaning that the distance between the two poles is 0 m.

Each interior angle of the decagon is ((n-2) * 180)/n= 144 degrees. So if D is shifted over to J which is 6 or 4 angles over, x= 144 * 6 or 144 * 4= 864 or 576 degrees. Neither angle is less than 180 degrees, so I'm not sure if the problem is correct.

An area of a prism is the area of the base time the height. Box A's area is just 4 * 10 * 3= 120in^3. Box B's area is the area of the base triangle (8/2) * 3= 12 times the height 6, so 12 * 6= 72in^3. Since 120>72, Box B is made of less cardboard.

\(\sqrt{x}-9=8\)

Add 9 to both sides

\(\sqrt{x}=17\)

Square both sides

\(x=289\)

A cube with a volume of 1000 cm is a 10cm x 10cm x 10cm cube. This means that the largest cylinder that can fit in that cube is 10cm tall and has a diameter of 10cm. With that, the area of the cylinder is 25pi * 10= 250pi.

If there are only 3 types of birds, that means that the sum of two types of birds equals 6. Which means there are 3 birds of each type. 3 * 3= 9 birds.

In your previous question, I explained how parentheses are used in a sentence, maybe you can use that to answer these questions.
