Sea level would be 0

So if it is going -12 /ft/s then it is descending 12 feet per second

-120/-12 = 10

The correct answer would be 10 seconds

I hope this helps!

Cassandra is creating an animated short film, and she needs 35 frames per second of film. He already has at least 200 frames.

scZoUnD [109]

Answer: C) f ≥ 35s - 200

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

She needs 35 frames (f) per second (s) ( we have to multiply the number of frames by the number of seconds) f ≥ 35s

She has already 200 frames (since we already have, we can subtract that to the needed frames per second)

f ≥35s -200

Feel free to ask for more if needed or if you did not understand something.

Azlyn can ride her horse 15.2 miles per hour. She is in an endurance race that is 76 miles

Tema [17]

Step-by-step explanation:

Remember, math is a language

when you see per think fractions

15.2 miles per hour = 15.2 miles / 1 hour

since this is a fraction, Units can cancel just like numbers

To cancel miles and be left with hours rearrange the fraction

1 hour / 15.2 miles

then multiply by 72 miles

$\frac{1hour}{15.2miles} \times 72miles$

the miles cancel and youre left with hours!

so youd write and solve 72 / 15.2

faust18 [17]

Answer:

Linear Function

$y=4x+18$

Step-by-step explanation:

Let

x----> the time in hours

y----> the total inches of snow on the ground

we know that

The function that best model this situation is the linear function

$y=mx+b$

In this problem

$m=4\frac{in}{h}$

$b=18\ in$ ----> the y-intercept

substitute

$y=4x+18$
