True.
The Pythagorean theorem is a^2 + b^2 = c^2 where a^2 and b^2 are the two legs of the triangle (two sides connected by the right angle) and c is the hypotenuse (longest side, opposite the right angle).
To solve using the Pythagorean theorem, plug in sides AC and CB into a and b, then solve for c.
23^2 + 31^2 = c^2
529 + 961 = c^2
c^2 = 1490
c = √1490 = 38.601

<span>The elevation is 12,000 feet. the altimeter reading in an airplane is 17.00 in hg. this pressure is equal to:
There are 29.92inHg in 1 atm
thus
</span>17 inHg×(1 atm/29.92inHg)
=17/29.92
=0.5682 atm
Answer: 0.5682 atm
The length of the copy is 16.8 cm ,The length of the original is 25 cm.

What is Percentage ?</h3>
Percentage is a number or ratio that represents a fraction of 100
It is given that
A photocopier makes copies that are 40% larger than the original.
An original is 12cm long. Find the length of the copy.
The copy will be
140 % of 12 cm
140 * 12/100
16.8 cm
Therefore , the length of the copy is 16.8 cm.
A copy is 35cm long. Find the length of the original.
The original will be x
140 * x / 100 = 35
x = 35 * 100 / 140 = 25cm
The length of the original is 25 cm.
