canada has a population that is about one tenth as large as the united states. if canada's population is about 32 million about
trapecia [35]
In this problem it states that one tenth or only 10% is Canada’s population to the United States. Hence with the steps we can identify the population of the United States.
<span><span>1.       </span>10 % = 32 million or 0.1 = 32 million</span>
<span><span>2.       </span>Then 32 million / 0.1 = 320, 000, 000 million</span>

Therefore there are 320, 000, 000 million living in the United States
Adding one zero. Why the zeroes? It is the result because of the power of 10 in a hundred percent population coming from the Canada’s population. Take note that 100% = 320, 000, 000 million of the USA while 10% of it is Canada so we divide it by 0.1 which is 32, 000, 000 (the power of ten)

Answer: 3

Step-by-step explanation:

A simple way to calculate the distance between numbers on a number line is to count every number between them. A faster way is to find the distance by taking the absolute value of the difference of those numbers. We have to find PQ. TAking the difference we have 94-91= 3.

Applying log rules leaves us with the following equation:

x^2 + 8 = 6x

Change to standard form and solve using factoring.

x^2 - 6x + 8 = 0

(x - 4)(x - 2) = 0

x = 4

x = 2

Hope this helps!
