The Baleen whale is the largest animal on earth yet it survives by consuming some of the smallest organisms in the ocean. What must be true in order for the Baleen whale to be sustainable? There must be enough Phytoplankton to support enough Krill to sustain the whale.

The number of Krill is the only thing that matters in the environment because Krill are photosynthetic.

The number of Krill is the only thing that directly affects the whale because its the only thing the whale eats.

The whale can easily find other sources of food in the ocean to sustain itself.

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
