A scuba diver dives 243 feet into the ocean and then swims up 156
wariber [46]

Answer:

Her final position would stop at -87.

Step-by-step explanation:

As she dove 243 feet into the ocean, that means she went down. Therefore she's currently at -243, however she swam up 156 feet ending her up at -87. If that was kinda complicated, then use -243+156 and you'll get -87.

What percentage of the people liked Rocky the most ?
Ede4ka [16]

Answer:

15%

Step-by-step explanation:

The amount of people who likes Titanic is 25%, because there are 360° in a circle and 90° is used for Titanic. Hence

\frac{90}{360}  =  \frac{25}{100}

To find the percentage of people who liked Rocky the most, we subtract the rest from the total (100%)

100 - 25 - 20 - 30 - 10 = 15

Therefore, 15% of the people liked Rocky the most.
