How do you explain ratios?

Mathematics

A ratio is the part divided by the whole. Johnny took 3 pieces of pizza when the whole pizza had 8. Johnny has 3/8 (3 out of 8) pieces of pizza, or .375 parts. To find that number, literally divide your part from your whole to get the decimal form.

Using the right triangle below. What is the name for side AC ?
irga5000 [103]

Answer:

B) Adjacent

Step-by-step explanation:

The hypotenuse will ALWAYS be designated as the longest side in a right triangle.

Pretend that the angle (the one with the round line) is an eyeball that is looking outwards. The eye is looking out at side BC. That means that line BC is opposite of the angle.

This leaves one side left: the adjacent side. The adjacent side is the side next to the angle. But it is the side that is NOT the hypotenuse.

Write an equation where the left side is your power of 10 times n and the right side is the result of multiplying 0.1515... by t
Neko [114]

Answer:

n10^x = 0.1515x

Step-by-step explanation:

Required

Translate the statements to algebraic expression

Represent the power with x;

So, the left hand side is

<em>Power of 10: </em>10^x<em />

<em>Times n: </em>10^x * n<em />

<em />

The right hand side is:

<em>0.1515 * power of 10: </em>0.1515 * x<em />

Equate the right hand side to the left:

10^x * n = 0.1515 * x

n10^x = 0.1515x

Hence;

<em>The required expression is </em>n10^x = 0.1515x<em />
