STEP THREE: Find the number of large shirts.

6 × 3 = 18 shirts

After a cleanup, algae covers 2 miles of a coastline. The length of the coastline covered after the cleanup is $\frac{1}{3}$

3​​ of the previous length. How many miles of the coast did the algae previously cover?

Answers

The miles previously covered by algae is 6 miles

let m represent the miles of the coastline covered by algae before the clean-up  

fraction of miles covered after the clean-up = [tex]\frac{1}{3}[/tex] x m = [tex]\frac{1}{3}m[/tex]

miles covered after the clean-up = 2 miles

[tex]\frac{1}{3}m[/tex] = 2 miles

to determine the value of m, make m the subject of the formula.

To do this, take the following step :

multiply both sides of the equation by 2

m = 2 miles x 3

m = 6 miles

Answer:

x = 2

Step-by-step explanation:

h(x) = -3x + 2

In this question, h(x) has the same meaning as y, so though this is not a standard practice, rewrite the question as

y = -3x + 2

What the question is telling you is that y = - 4

-4 = -3x + 2                  Subtract 2 from both sides

-4-2 = -3x                    Combine

-6 = - 3x                       Divide by - 3

A bacteria culture doubles every 5 hours. Determine the hourly growth rate of the bacteria
culture. Round your answer to the nearest tenth of a percent.

Answers

[tex]\sqrt[5]{2}-1 = 1 +x - 1[/tex]Answer:

14.87% per hour

Step-by-step explanation:

Let's pretend we're starting with one bacteria.

Double of one is two

We're gonna have to use this formula: A = P(1 + x)ⁿ

A = Amount (which is 2)

P = Initial amount (which is 1)

x = percentage per time (hour)

n = amount of time (hours)

So our equation will look like this:

2 = 1(1 + x)⁵

First, we need to root both sides to isolate (1 + x)

[tex]\sqrt[5]{2} = \sqrt[5]{(1+x)}[/tex]

[tex]\sqrt[5]{2} = 1 +x[/tex]

Then subtract both sides by 1

[tex]\sqrt[5]{2}-1 = 1 +x - 1[/tex]

[tex]x=\sqrt[5]{2}-1[/tex]

[tex]\sqrt[5]{2} = 1.148698355[/tex]

1.148698355 - 1 = 0.148698355

Lamar works as a tutor for $12 an hour and as a waiter for $14 an hour. This month, he worked a combined total of 100 hours at his two jobs.
Let "t" be the number of hours Lamar worked as a tutor this month. Write an expression for the combined total dollar amount he earned this month.

total earned (in dollars) =__________

Answers

Answer:

-2t + 1400

Step-by-step explanation:

If t represents the number of hours Lamar worked as a tutor, the number of hours he worked as a waiter can be represented by 100 - t.

Create an equation to represent the situation:

12t + 14(100 - t) = total earned

Simplify:

12t + 1400 - 14t = total earned

-2t + 1400 = total earned

So, the expression for the amount he earned is -2t + 1400
