Supplementary adjacent angles form a "linear pair." Together, they make a line. The angle supplementary to 85° will be slightly obtuse, just as 85° is slightly acute.

The half-life of a radioactive material is about 2 years. How much of a 5.0 kg sample of this material will remain after 4 years
HACTEHA [7]

The remaining amount after 4 years is 1.25 kg

<h3>How to determine the remaining amount?</h3>

The half life of a function is represented as:

A = A_o * (1/2)^{t/h}

Where

Ao represents the initial amount

So, we have:

A = 5 * (1/2)^{t/2}

In 4 years, t = 4.

So, we have:

A = 5 * (1/2)^{4/2}

This gives

A = 5 * (1/2)^2

Evaluate the expression

A = 1.25

Hence, the remaining amount after 4 years is 1.25 kg

Classify each number according to which sets of numbers it belongs in:
True [87]

Answer:

Natural, integer, rational:  10, 9, 3(12-\frac{2}{2})

Integer, rational:  -6

Rational:  3.7, 3.3333333

Irrational: \pi, 1.41421356

Step-by-step explanation:

Given numbers:

10,\pi, -6, 3.3333333333, 9, 3.7, 3(12-2/2),1.41421356

To classify them in natural integer, whole rational or irrational numbers.

Solution:

Natural numbers are whole numbers stating from 1.

{1,2,3,4,5,6..........}

Whole numbers are integers starting from 0.

{0,1,2,3,4,5...........}

Integers are all real numbers that do not include decimals or fractions.

{.............-4,-3,-2,-1,0,1,2,3,4.........}

Rational numbers are those numbers which can be represented as fraction of whole numbers. For example:

-1.5=-\frac{3}{2}

0.1111.....=\frac{1}{9}

5=\frac{5}{1}

Irrational numbers are those numbers which cannot be represented as simple fractions.

<em>Based on the above definitions, we can classify numbers.</em>

1) 10

Natural, Integer, Rational

2) \pi

Irrational

3) -6

Integer, Rational

4) 3.33333333333

Rational

5) 9

Natural, Integer, Rational

6) 3.7

Rational

7) 3(12-\frac{2}{2})=3(12-1)=3(11)=33

Natural, Integer, Rational

8) 1.41421356

Irrational
