After 3 hours, you will be on 450 mile marker.

Step-by-step explanation:

<u>step 1:</u> At start, the number in the mile marker is 100

<u>step 2:</u> After 4 hours, the number in the mile marker is 300

<u>step 3:</u> The difference of 300-100= 200. In 4 hours you crossed 200 mile markers.

<u>step 4:</u> Therefore, for 1 hour you can cross= 200/4= 50 mile markers.

For 3 hours, the number of mile markers crossed= 3*50= 150 mile markers.

<u>step 5:</u> After 3 hours, the number in the mile marker will be= 300+150= 450

P=$222 r=12% Y=10 A=?

To solve for the A or the principal amount plus interest you can use two formulas:

A = P + I

Where: P = Principal
             I  = Interest

or you can use 

A = P (1+ rt)

Where: P = principal
             r  = rate in decimal
             t  = time in years

With your given you can use the second one, without having to use the first. 
Given that the Principal amount is $222 and the rate is 12% and time is 10 years, we first need to convert your rate into decimal by dividing the value in percent by 100 which will yield 0.12. 

Then now we can just input the data that you know into the formula:
A = P(1+ rt)
   = $222(1 + (0.12)(10))
   = $222(2.2) 
   = $488.40

Your A is then equal to $488.40

If you need to get the simple interest all you need to use is the first formula given:

A = P + I
for the interest you transpose the P to the side of the A and you will get:
I = A - P
  = $488.40 - $222
  = $266.40

$266.40 is the added interest to the principal amount.

Answer:

  9n^4

Step-by-step explanation:

The divisor and quotient can be interchanged to find the divisor:

  \dfrac{18n^6+27n^5-36n^4}{2n^2+3n-4}=\boxed{\text{Blank 1}}

Such division is carried out by first finding the quotient of the highest-degree terms:

  \dfrac{18n^6}{2n^2}=\dfrac{18}{2}n^{6-2}=9n^4

This value is used to multiply the denominator and subtract that product from the numerator to find the new numerator. The new numerator is zero, so the value that goes in Blank 1 is ...

  9n^4

_____

The attachment shows the long division.
