Answer:

70 members in 2016

Step-by-step explanation:

In 2016

Let the number of members= x

They all paid y amount

Total fees= 42

Xy= 42...... equation 1

In 2017

Members= x+20

They paid y-0.1

Total fees = 45

(X+20)(y-0.1)= 45…equation 2

Xy -0.1x +20y -2= 45

Using values from equation 1

42-0.1(42/y) +20y -2= 45

-4.2/y+20y-5= 0

20y² -4.2 -5y = 0

100y² -25y -21= 0

Solving quadratically

Y= 0.6 or -0.35

We are dealing with price so y Is

definitely a positive number

Y= 0.6

If y= 0.6

Solving for x

Xy= 42

X= 42/0.6

X=70

There were exactly 70 members in 2016

a^2+b^2=c^2
a=b because the sides are equal (11)

Please help me with this question!!

Answer:

  1. rational
  2. irrational
  3. irrational
  4. irrational
  5. √7, it is irrational

Step-by-step explanation:

A <em>rational</em> number is one that can be expressed as the ratio of two integers. All fractions that have integer numerators and (non-zero) denominators are <em>rational</em> numbers. Any finite decimal number, or any repeating decimal number, is a rational number. These can always be expressed as the ratio of two integers. For example, 0.4040... = 40/99, and 0.286 = 286/1000.

To make an irrational sum, at least one of the contributors must be irrational. You want an irrational 2-number sum that has 7/8 as one of the contributors. Since 7/8 is rational, the other contributor must be irrational.

__

<u>Step 1</u>. The number 7/8 is <em>rational</em>.

<u>Step 2</u>. The desired sum is <em>irrational</em>.

<u>Step 3</u>. The rule <em>rational + </em><em>irrational</em><em> = irrational</em> applies.

<u>Step 4</u>. An <em>irrational</em> number must be chosen.

Step 5. √7 will produce an irrational sum, because <em>it is irrational</em>.
