$\sqrt{33 + \sqrt{4 + \sqrt{50 \cos(60°) } } }$

Now, we know cos(60°) = $\frac {1}{2}$ . So put the value there.

$\sqrt{33 + \sqrt{4 + \sqrt{50 \times \frac{1}{2} } } } \\ = \sqrt{33 + \sqrt{4 + \sqrt{25} } } \\ = \sqrt{33 + \sqrt{4 + 5 } } \\ = \sqrt{33 + \sqrt{9} } \\ = \sqrt{33 + 3} \\ = \sqrt{36} \\ = 6$

Hence LHS = RHS [Proved]

Hope you could understand.

Answer the above question

Svetach [21]

Answer:

Using Pyhagoras Theorem for the right-angled triangle ABO,

h² = 12² + 16² = 400.

∴ The length of the side of the rhombus is 20 cm.

★½×24×32 = 20×h

∴ h= 19.2 cm.

here's the equation: x+x+(x+12)+ 1/2(x+12) =81

combine like terms

(x+x+x+1/2x) + (12+6) = 81

simplify

7/2x +18=

subtract 18 from both sides.

7/2x=63

multiply by reciprocal (aka 2/7)

x=18

18+12=30 so celia gave 30.

Hope this helps!

A jazz concert brought in $134,000 on the sale of 8,500 tickets. If the tickets sold for $10 and $20 each, how many of each type

WINSTONCH [101]

Answer:

3600 $10 tickets

4900 $20 tickets

Step-by-step explanation:

We can use variables to represent the different types of tickets. Let "x" represent the amount of $10 tickets and "y" represent the amount of $20 tickets. Now we can set up a system of equations.

<h3>Setting up a System of Equations</h3>

We know that in total, 8500 tickets were sold. Therefore...

$x+y=8500$

Or in other words, "the amount of $10 tickets plus the amount of $20 tickets is equivalent to 8500 tickets in total".

We also know that $134,000 was made. Therefore...

$10x+20y=134000$

Or in other words, "10 times the amount of $10 tickets plus the 20 times the amount of $20 tickets is equivalent to 134000". Notice that since each ticket costs $10/$20, we have to multiply each variable by that value. We can now solve this system of equations.

<h3>Solving the System of Equations</h3>

$x+y=8500\\10x+20x=134000$

We can solve this system of equations using the elimination method. First, make either the x or y value equivalent in both equations. To do this, we can multiply a whole equation by a certain value.

Multiply the first equation by 10:

$10x+10y=85000\\10x+20y=134000$
