weeeeeb [17]

Answer:

Option c. 104 people

Step-by-step explanation:

For 1 desk : 4 people

For 2 desks: 6 people

For 3 desks: 8 people

<em>For 51 desks: </em>

<em>We can see the pattern in the number of people that can be seated on the tables. </em>

Using arithmetic series: 4,6,8,....

a(n) = a1 + (n-1)d

n = 51

d = a2 - a1 = 6 - 4 = 2

a(51) = 4 + (51 - 1) 2

= 4 + (50)2

= 4 + 100

= 104

The legs of a right triangle are 3 units and 8 units. What is the length of the hypotenuse? Round your answer to the nearest hun

Alisiya [41]

Answer:

<h2>8.54 units</h2>

Step-by-step explanation:

Given,

Perpendicular ( p ) = 8 units

Base ( b ) = 3 units

Hypotenuse ( h ) = ?

Using Pythagoras theorem:

${h}^{2} = {p}^{2} + {b}^{2}$

plug the values

${h}^{2} = {8}^{2} + {3}^{2}$

Evaluate the power

${h}^{2} = 64 + 9$

Calculate the sum

${h}^{2} = 73$

Squaring on both sides

$h = \sqrt{73}$

Calculate

$h = 8.54$ units

Hope this helps..

Best regards!
