Answer:
The number of 43 cent stamps Esmeralda bought is <u>19</u>.
Step-by-step explanation:
Given:
Esmeralda bought 12.22 worth of 43 cent stamps and 81 cent stamps. The number of 81 cent stamps was 14 less than the number of 43 cent stamps.
Now, to solve the equation 0.43 s + 0.81 ( s − 14 ) = 12.22 for s and to find the number of 43 cent stamps.
Let the number of 43 cent stamps be 
And, the number of 81 cent stamps be 
So, to solve equation for 



<em>Adding both sides by 11.34 we get:</em>

<em>Dividing both sides by 1.24 we get:</em>

<em>The number of 43 cent stamps = 19.</em>
Therefore, the number of 43 cent stamps Esmeralda bought is 19.
We are given the two sides of the right triangle therefore we can use the pythagorean theorem to solve for the third side. This theorem states that, in a right triangle the square of the hypotenuse is equal to the sum of the square of each leg.
c² = a² + b²
70² = 35² + b²
b = √70² - 35²
b = 60.62 feet

Answer:
y = 2x -1
Step-by-step explanation:
y = mx + b
y = 2x + b
7 = 2(4) + b
7 = 8 + b
-8 -8
-1 = b
Answer: There are 6045 millions world population during the period of 1950 to 2000.
Step-by-step explanation:
Since we have given that
The world population in the second half of the 20 the century by the equation:

We need to find the average world population during the period of 1950 to 2000.
So, there are 50 years between 1950 to 2000.
So, t = 50 years.
Therefore, the average population would be

Hence, there are 6045 millions world population during the period of 1950 to 2000.
