<h2>Answer</h2>

1.5n-3.2

<h2>Explanation</h2>

First, we need to distribute -1.5. To do it we just multiply each term inside the parenthesis by -1.5:

-1.5(4-n)+2.8

-1.5*4-1.5*-n+2.8

-6+1.5n+2.8

Now we just need to combine like terms:

1.5n+2.8-6

1.5n-3.2

Answer: 8.8 + 1.5n

Work:
The first thing you need to do is distribute the -1.5 to the terms within the parentheses. Doing so simplifies the expression to 6 + 1.5n +2.8. Then combine like terms, so the 6 and the 2.8, which simplifies the expression to 8.8 + 1.5n, which is the answer.

What are the steps to construct parallel lines using a compass and straightedge?
nevsk [136]

See if the distance between the two lines is consistent with a compass.

Make sure the lines intersect at right angles with the corner of a piece of paper.

Measure each of the angles with a straightedge.

There is no way to ensure you have constructed parallel lines.

I'm studying a new bacteria that doubles in numbers every 25 minutes. If i start with 50 bacteria, how long until i have 5 milli
dimaraw [331]

Answer:

415.63 minutes

Step-by-step explanation:

Growth can be represented by the equation A=A_0e^{rt}. We can find the rate at which it grows by using t=25 minutes and \frac{A_{0}}{A} =2 or double the amount at that time. The first step we always take is to divide A_0 by A.

[tex]\frac{A_{0}}{A}=e^{rt}\\2=e^{r(25)}

2=e^{(25)r}

To solve for r, we will take the natural log of both sides and use log rules to isolate r.

ln 2=ln e^{(25)r}\\ln 2=25r (ln e)\\\frac{ln2}{25} =r

We know lne=1 so we were able to cancel it out and divide both sides by 25.

We solve with a calculator \frac{ln2}{25} =r\\0.0277=r

We change 0.0277 into a percent by multiplying by 100 to get 2.77% as the rate.

The equation is A=A_0e^{0.0277t} .

We repeat the step above substituting A=5,000,000, A_0=50, and r=0.02777. Then solve for t.

5000000=50e^{0.0277t}\\\frac{5000000}{50} =e^{0.0277t}\\100000=e^{0.0277t}\\ln100000=lne^{0.0277t}\\ln100000=0.02777t(lne)\\\frac{ln100000}{0.0277} =t

t=415.63 minutes
