Angles in a triangle total 180°

180=128+5x+10+9x
180-128-10=5x+9x
42=14x
x=3

Answer:

The value of x is 3.

Step-by-step explanation:

It is given that the angles of a triangle are 128, 5x+10 and 9x.

According to the angle sum property of a triangle, the sum of all interior angles of a triangle is 180 degrees.

128+5x+10+9x=180

138+14x=180

14x=180-138

14x=42

Divide both sides by 14.

x=3

Therefore the value of x is 3.

The population of bacteria in a certain culture can be modeled by the function P(t)=10000(1.03)^t. Is the population of bacteria
ch4aika [34]

Answer:

The population of bacteria is increasing.

Step-by-step explanation:

The function modelling the population of bacteria in the given culture is an exponential function; We have a base 1.03 and an exponent t. An exponential function is said to be increasing if the base is strictly greater than 1, this implies that the population of the bacteria is increasing as t increases from 0 to infinity.

How to <br> Write <br> 3/9<br> in simplest form.
White raven [17]
To write it in simplest form, you must find a common factor.

In \frac{3}{9}, 3 is a factor of both 3 and 9

3÷3=1 and 9÷3=3

So \frac{3}{9} =  \frac{1}{3}

\frac{1}{3} is your answer in simplest form.
