DeepSea Challenger’s descent was a change in depth of (-4) feet per second.We can use the equation y = -4x to model this relationship, where y is the depth (-35,814 ft) and x is the time in seconds that have passed. How many seconds does this model suggest it would take for DeepSea Challenger to reach the bottom?(round to the nearest tenth)
* Explain how you got your answer.

Answers

Answer 1

Answer:

Step-by-step explanation:

x = -35,814 ft ⋅ (1 sec)/(-4 ft) = 8,953.5 sec

Answer 2

The required model suggests that it would take approximately 8957.5 seconds for DeepSea Challenger to reach the bottom.

What is proportionality?

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

To find the time it takes for the DeepSea Challenger to reach the bottom, we need to find the value of x when y = -35,814 ft.

We can substitute the desired depth into the equation y = -4x:

-35,814 = -4x

35,814 = 4x

x = 35,814 / 4

x = 8953.5 seconds

So, the model suggests that it would take approximately 8957.5 seconds for DeepSea Challenger to reach the bottom.

Dinorah weighs 30.5 kg. Her dog weighs 6.1 kg. How many times as much does Dinorah weigh as her dog?

Answers

Answer:

5 times

Step-by-step explanation:

Given

[tex]D = 30.5kg[/tex] -- Dinorah's weight

[tex]d = 6.1kg[/tex] --- Her dog's weight

Required

Determine how much she weighs as much as her dog

To do this, we simply divide her weight by her dogs.

[tex]n = \frac{D}{d}[/tex]

[tex]n = \frac{30.5kg}{6.1kg}[/tex]

[tex]n = \frac{30.5}{6.1}[/tex]

[tex]n = 5[/tex]

-1 is now 8

X^2 + 3x + 8 = 35

Subtract 8 from both sides so it now equals 27

The greatest number of bags she can make without having any stickers or pencils left over is 18 bags.

Step-by-step explanation:

The best way to go about this is by dividing the total number of pencils and stickers by the answer choices given and starting with the highest number (27). We already know that 27 goes into 54 twice without anything left over, but can only go into 36 once while having 9 leftover. This would eliminate 27 as an answer choice as it does not meet the criteria.

Repeat the same process with 18, so 54 divided by 18 is 3, and 36 divided by 18 is 2. There is nothing left over, every bag will have an equal number of pencils and stickers. With this answer, the question criteria is true, making this the correct answer choice.
