Answer:

Yes

Step-by-step explanation:

If the longest side squared is equal to the sum of the squares on the other 2 sides then they form a right triangle

longest side = 7.5

7.5² = 56.25

2.1² + 7.2² = 4.41 + 51.84 = 56.25

Thus the 3 values form a right triangle.

Answer: Yes, the three measurements form a right angled triangle

Step-by-step explanation: A right angled triangle can be solved by the Pythagoras theorem, that is, when one side is missing. The formula is

AC^2 = AB^2 + BC^2

(The square of the longest side equals to the sum of the square of the other two sides)

Where AC is the longest side and AB and BC are the other two sides.

In the question given, the longest side is 7.5, and so substituting for the values, we can write out the Pythagoras theorem as follows;

7.5^2 = 7.2^2 + 2.1^2

56.25 = 51.84 + 4.41

56.25 = 56.25

Since the Left Hand Side equals to the Right Hand Side, then the dimensions given in the question forms a right angled triangle

The easiest way to determine the score is to use a calculator or spreadsheet and the appropriate probability function.

If you want the top 10%, the score corresponds to the 90th percentile. That score is 316.

If you want the top 15%, the score corresponds to the 85th percentile. That score is 313.

What is the simplified value of the exponential expression 64 1/4

katrin [286]

$\bf a^{\frac{ n}{ m}} \implies \sqrt[ m]{a^ n} 
\qquad \qquad
\sqrt[ m]{a^ n}\implies a^{\frac{ n}{ m}}\\\\
-------------------------------\\\\
64^{\frac{1}{4}}\qquad \boxed{64=2^6}\qquad (2^6)^{\frac{1}{4}}\implies 2^{6\cdot \frac{1}{4}}\implies 2^{\frac{6}{4}}\implies 2^{\frac{3}{2}}
\\\\\\
\sqrt[2]{2^3}\implies \sqrt{2^{2+1}}\implies \sqrt{2^2\cdot 2^1}\implies 2\sqrt{2}$

Please answer this question i really want answers :(

Based on the hints of distinguishing between radical and non-radical numbers, we have the following lists:

$\sqrt{3}$ , $2.\overline{2}$ , 2.5, $\sqrt{5}$
3.01, $3.\overline{01}$ , $3.\overline{1}$ , $\sqrt{9}$
$-4.\overline{1}$ , - 4.1, 4.01, $\sqrt{17}$
- 2.5, $-\sqrt{5}$ , $\sqrt{6}$ , 2.5

<h3>How to order numbers from least to greatest</h3>

In this question we must order sets of numbers in ascending order. A hint consists in comparing non-radical numbers with the closest radical numbers whose results are integers.

In consequence, we obtain the following orders:

$\sqrt{3}$ , $2.\overline{2}$ , 2.5, $\sqrt{5}$
3.01, $3.\overline{01}$ , $3.\overline{1}$ , $\sqrt{9}$
$-4.\overline{1}$ , - 4.1, 4.01, $\sqrt{17}$
- 2.5, $-\sqrt{5}$ , $\sqrt{6}$ , 2.5
