If the descent starts from 12 m above theground level; how long will it take to reach −468 m?10. Ryan was playing a game where catching a fish in the basket adds 10 points to his score. If hecatches an octopus instead, he loses 5 points. What is his total if he catches 3 fish and 5 octopus?

She wants to do it in 5 equal descents.(i) Use the number line to find how far the diver should travel in each of the 5 descents.(ii) To solve this problem, you can set up a division problem: _____.−100? =12. Show that:−5 (12 + 7) = (-5 12) + (-5 7)× ×13. The fish in the pond below, carry somenumbers. Choose any 4 pairs and carry out fourmultiplications with those numbers. Now,choose four other pairs and carry out divisionswith these numbers.For example,1. (–13) × (–15) = 1952. (−24) ÷ 9 = −8314. Allen’s score in a video game was changed by -75 points because he missed some targets. He got -15points for each missed target. How many targets did he miss?15. Ned took a test with 25 questions. He lost 4 points for each of the 6 questions he got wrong andearned an additional 10 points for answering a bonus question correctly. How many points did Nedreceive or lose overall?16 Use the sign >, <, or = in the following: (Show all the steps of your calculations)(i) _______80 + 69 − 319 − 219 − 100 + 70 + 79(ii) __________19 + (− 40) − 37 32 + (− 66) − (− 39)

A 25 foot ladder is set against the side of a house so that it reaches up 15 feet. If Camden grabs the ladder at its base and pulls it 3 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 12 ft.) Round to the nearest tenth of a foot.
