What is the length of the hypotenuse of a 45°-45°-90° triangle with leg length 5V3?

Mathematics

timama [110]2 years ago
5 0

Answer:

5\sqrt{6}

Step-by-step explanation:

The easiest way to do this problem is to know that the hypotenuse of a 45-45-90 triangle is equal to \sqrt{2} times the length of a leg.  

So, in your problem the hypotenuse = \sqrt{2}(5\sqrt{3}) = 5\sqrt{6}.   Another way to solve the problem is to use the Pythagorean theorem, but that is a longer way to solve it.

weqwewe [10]

133 adult tickets were sold.

Step-by-step explanation:

Given,

Total tickets sold for school play = 399

Let,

x represent the number of children tickets sold.

y represent the number of adult tickets sold.

According to given statement;

x+y=399      Eqn 1

x = 2y           Eqn 2

Putting value of x from Eqn 2 in Eqn 1

2y+y=399\\3y=399

Dividing both sides by 3

\frac{3y}{3}=\frac{399}{3}\\y=133

133 adult tickets were sold.

Elis [28]

Answer:

$129 000/yr

Step-by-step explanation:

Weighted average is used to answer this question.

<em>total employees are 20</em>

10 employees make 80 000

<em>total earning for 10 employees </em>= 80 000 * 10 = 800 000 (multiplying)

6 employees make 150 000

<em>total earning for 6 employees= </em>150 000 * 6 =900 000<em> (multiplying)</em>

4 employees make 220 000

<em>total earning for 4 employees </em>= 220 000 * 4 = 880 00<em>0 (multiplying)</em>

<em />

<em>To calculate weighted average all the totals are added and then divide by total number of employees.</em>

<em>weighted average =</em> (800 000 + 900 000 + 880 000)/20

<em />

<em>weighted average = </em>2580000/20

<em />

<em>Weighted average = </em>129 000

<em />
