A robot submarine dives 803 ft to the ocean floor. It rises 215 ft as the water gets shallower. Then the submarine dives 2619 ft into a deep crevice. Next, it rises 734 ft to photograph a crack in the wall of the crevice. What is the location of the crack in relation to sea level?

You make five withdrawals of equal amounts from your bank account. The total amount you withdraw is $360. What is the change in your account balance each time you make withdrawal?

Answer 1

The numbers ordered from least to greatest are -7, -2.1, 2, 2.236 (√5), 3, 3.5. The submarine is at a location 2473 ft below sea level after the series of dives and ascents. Each bank account withdrawal was $72.

Step-by-step explanation:

To graph the numbers 3.5, -2.1, √9, -7, 2, √5 on a number line and arrange them from least to greatest, first evaluate the square roots. √9 is 3, and √5 is approximately 2.236. Now, you can place all the numbers on the number line. The order from least to greatest is -7, -2.1, 2, 2.236 (√5), 3, and 3.5.

For the submarine's location in relation to sea level, start by subtracting 215 ft from the initial dive of 803 ft, leaving the submarine 588 ft below the surface. Then, after diving an additional 2619 ft, it is 3207 ft below the surface. Rising 734 ft brings it to a depth of 2473 ft below sea level. Thus, the location of the crack is 2473 ft below sea level.

If you make five equal withdrawals from your bank account totalling $360, each withdrawal is $360 divided by 5, which is $72. So, each time you withdraw, your account balance decreases by $72.
