Answer: Could you give us the graph?
Step-by-step explanation:
Answer:
6, 8, and 10.
Step-by-step explanation:
You could work this out with the pythagorean theorem, by proving that 6^2, 36, plus 8^2, 64, equals 100. The fastest way, however, is to use pythagorean triples. These are predetermined sets of numbers that work as side lengths for right triangles. The first two are 3, 4, and 5, which form a right triangle, and 6, 8, and 10, shown here.
Q1. Look at the picture.
Q2. Look at the picture.
Q3.
Put the value of x = 2 to the equation 3x + y = 5:
<em>subtract 6 from both sides</em>
Q4.
Substitute (*) to (**):
<em>use distributive property</em>
<em>add 33 to both sides</em>
<em>divide both sides by 11</em>
Put the value of m to (*):
Q5.
w - width
3w - length
24 in - the sum of length and width
The equation:
<em>divide both sides by 4</em>
Answer:
0.3kg
Step-by-step explanation:
Since the weight of 120 books is 36kg, the weight per book will be:
= 36kg / 120
= 0.3kg
The square root of a whole number will be rational if the whole number is a perfect square (i.e 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144 etc) and irrational otherwise.
Rational number is a number that can be described as m/n
so a fraction can be a rational number, 0.8=4/5
Irrational numbers can't be written as a fraction
The part about the number having to be a perfect square is still correct, if it's not a prefect square than it will just keep going(a decimal that never ends)
for example the square root of 0.64 is 0.8
and the square root of 10 is 3.162277...
as you can see the 0.64 one ends and is rational, whereas the 10 one just keeps going and is irrational.
