Answer:

The value of x is 2.7  and the equation used for finding the value of x is 7.5 = 2.1 + 2x.

Step-by-step explanation:

As given

The isosceles triangle has a perimeter of 7.5 m  .

if the shortest side, y measures 2.1 m

In the isosceles triangle two sides of the triangle are equal .

Let us assume that the two equal sides each of length x .

Thus

Perimeter = Sum of all sides

Perimeter = x + x + y

7.5 = 2x + 2.1

7.5 - 2.1 = 2x

5.4 = 2x

x = \frac{5.4}{2}

x = 2.7 m

Therefore the value of x is 2.7  and the equation used for finding the value of x is 7.5 = 2.1 +2x.

Is 1.5 over 7.5 a rational number
Tomtit [17]
Yes, because you can simplify it to .2 which can be written as a fraction. Irrational numbers are those ones that keep going with an infinite string of numbers past the decimal.

The country of Sylvania has decided to reduce the number of its illiterate citizens by 3/5 each year. This year there are 9000 i
KonstantinChe [14]

Answer:

P(t)= 9000(0.4)^t

Step-by-step explanation:

Generally, we have an exponential function as follows;

P(t)= I(1 - r)^t

This case represents a decay ( decrease in value)

from what we have;

I represents the initial value, whereas r is the rate of change

From the question, we have that the change rate is the fraction 3/5

Writing this as a decimal, it is 0.6

substituting this back into the equation, we have;

P(t)= I(1-0.6)^t

P(t)= I(0.4)^t

I in this case is 9,000

So we have it that;

P(t) = 9000(0.4)^t
