Answer:

  A. About 4,900 ft

Step-by-step explanation:

We want h such that ...

  5 = 10·ln(h) -80

  8.5 = ln(h) . . . . . . . add 80, divide by 10

  e^8.5 = h ≈ 4914.8 . . . . take the antilog

  h ≈ 4900 . . . . feet

Fiona needs to choose a five-character password with a combination of three letters and the even numbers 0, 2, 4, 6, or 8.
katen-ka-za [31]

The total outcomes of creating a password is 20

<h3>How to determine the total outcomes creating different passwords with the given characters and numbers?</h3>

The given parameters are

Letters = 3

Digits = 5 digits i.e 0, 2, 4, 6, or 8.

From the question, the digits and the letters cannot be repeated.

So, we have:

Possible letters = 3 characters (position fixed)

Digits = 2 numbers

So, the total outcomes of creating different passwords is

Total = 1 * 1 * 1 * 5 * 4

Evaluate the product

Total = 20

Hence, the total outcomes of creating a password is 20

The perimeter of a rectangular rug is 40 ft. It's length is 12 ft. What is it's width?
Alexus [3.1K]

Answer:

<h2>The answer is 8 ft</h2>

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

perimeter = 40 ft

length = 12 ft

Substitute the values into the above formula and solve for the width

That's

40 = 2(12) + 2w

40 = 24 + 2w

2w = 40 - 24

2w = 16

Divide both sides by 2

We have the final answer as

<h3>8 ft</h3>

Hope this helps you

You can buy a 6 hour phone card for $5, but the fine print says that each minute you talk actually costs you 1.5 minutes of time
Snowcat [4.5K]

we are given

You can buy a 6 hour phone card for $5

so, total hours = 6 hours

now, we can change it into min

6 hours = 6*60 min

6hrs=360min

Let's assume

x is the number of actual minutes talked,

y is the called number of minutes left on the card

and we are given

each minute you talk actually costs you 1.5 minutes of time

so, we get equation as

y=360-1.5x
