Mark is typing up the final copy of his essay for class. he can type 20 words per minute. if his final essay is 5356 words in length, how long did it take mark to finish typing his essay? round to the nearest minute.

It takes Mark 268 minutes to type 5356 words

Step-by-step explanation:

We can easily solve this using proportion;

let x be the number of minutes that will take Mark to type 5356 words,

20 words    = 1 minute

5356 words= x

Cross multiply

20x = 5356

Divide both-side of the equation by 20

20x/20 = 5356/20

(On the left-hand side of the equation 20 at the numerator will cancel-out the 20 at the denominator leaving us with just x, while the right-hand side of the equation 5356 will be divided by 20)

x = 5356/20

x=267.8

x≈268

Therefore, it takes Mark 268 minutes to type 5356 words

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
