A triangle has a perimeter of 72 units, and two of its sides measure x units and 3x units, respectively. Which inequality repres
blagie [28]

Answer:

x

Step-by-step explanation:

Given: Perimeter of triangle= 72 units

          Measure of one of the side= x units

          Measure of second side = 3x units

We know the perimeter of triangle is equal to sum of all sides.

Now, finding the possible value of x

forming an inequality to determine the value of x

Remember triangle has three sides, however, measure of only two sides are given.  

⇒ x+3x < 72\ units

⇒ 4x

Dividing both side by 4

⇒ x < 18

∴ The inequality to represents all possible values of x is x < 18

A country's population in 1991 was 136 million. In 2000 it was 141 million. Estimate the population in 2016 using the exponentia
xeze [42]
Answer: The population will be about 150 million in the year 2016.

First, let's start by using the given equation. Fill in the values that you know and solve for the missing piece.

Our equation is:

141 = 136e^(9k)    I used 9 because 2000 is 9 years past 1991.

(141/136) = e^9k   Divide both sides by 136

ln (141/138) = 9k    Take the natural log of both sides, the e is removed.

0.004 = k    Find the natural log of 141/136 and divide it by 9.

Now, we have a new equation. Just plug in 25 for x and you will get 150. We used 26 because 2016 is 25 years past the starting year of 1991.
