answer:

1 : 2.5

explanation:

given ratio: 12 : 30

divide by 12:

  • \frac{12}{12} : \frac{30}{12}
  • 1 : 2.5

n = 2.5

Solution:

<u>Note that:</u>

  • 12:30 = 12/30

<u>Simplify the denominator and the numerator.</u>

  • => 12/30 = 6/15 = 2/5 = 1/2.5
  • => 1/2.5 = 1:2.5 (In ratio form 1:n)

The simplified ratio form of 12:30 is 1:2.5.

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 16 miles per hou
Verizon [17]
We'll use variables to represent the speeds of the eastbound and westbound trains.

x will represent the speed of the eastbound train.
y will represent the speed of the westbound train.

The eastbound train is 16 mph faster than the westbound train. An equation can be made from this:

x  - y = 16

Subtraction is used, because it represents the difference in distances between the two trains if they travel the same direction.

After 4 hours, the trains are 800 miles apart. An equation can be made from this:

4x + 4y = 800

Addition is used, because the trains are heading in opposite directions, which means their distances from the starting point are added together.

Set the two equations up vertically:

x - y = 16
4x + 4y = 800

We will use elimination to solve for x.

Multiply the entire first equation by 4 so that the coefficients for y will be opposite numbers:

(x - y = 16) \times 4 = 4x - 4y = 64

4x - 4y = 64
4x + 4y = 800

Combine the two equations together to cancel out y:

8x = 864

Divide both sides by 8 to get x by itself:

x = 108

The speed of the eastbound train is 108 mph.

What is the relationship between the degree of a function and the degree of the derivative?​
Over [174]

Answer:

Graphing the derivative with the function can illustrate how to find these turning points. The function is increasing exactly where the derivative is positive, and decreasing exactly where the derivative is negative. On the graph of the derivative find the x-value of the zero to the left of the origin.
