Simple...what fun!

To solve for this type of problem...it's real simple!

I will show you the easiest and fastest way to solve...

so..you have...

$\frac{2}{5} = \frac{x}{35}$

Just..CROSS MULTIPLY!!

2*35=70
and
5*x=5x

Leaving you with....

5x=70

Easy...now divide!!

$\frac{5x}{5} = \frac{70}{5}$

x=14

To check your work...plug it in....

$\frac{2}{5} = \frac{14}{35}$

simplify...

14/7=2

and

35/7=5

Thus, your answer.

At the movie theater, child admission is $5.50 and adult admission is $8.60. On Saturday, 137 tickets were sold for a total sale

snow_tiger [21]

Answer:

The number of child tickets were sold is 75

Step-by-step explanation:

Given as :

The price of tickets for child admission = $5.50

The price of tickets for adult admission = $8.60

The total numbers of tickets sold = 137

The total price of tickets sold = $986.00

Let The number of tickets for child = C

The number of tickets for adults = A

So, According to question

A + C = 137

And 5.50 A + 8.60 C = 986

Solve the above equation

5.5 A + 5.5 C = 137 × 5.5

or, 5.5 A + 5.5 C = 753.5

Or, ( 5.5 A + 8.6 C) - ( 5.5 A + 5.5 C) = 986 - 753.5

Or, (5.5 A - 5.5 A) + (8.6 C - 5.5 C) = 232.5

Or, 0 + 3.1 C = 232.5

∴ C = $\frac{232.5}{3.1}$ = 75

And A = 137 - C = 137 - 75 = 62

Hence The number of child tickets were sold is 75. Answer

What is the height of the cone below?

Paul [167]

The height of the cone is h = 27

Formula:-

Step 1:-

The volume of the cone is V=\frac{1}{3} (base)(height)V=31(base)(height)

Given volume is V= 45 in^ 3

Given base of the cone is B= 5 in^2

Step 2:-

by using formula, we get solution

45 = \frac{1}{3} (5)(h)45=31(5)(h)

cross multiplication, we get

\frac{45 x 3}{5} =h545x3=h

<em>now simplification, the height of the cone is h = 27</em>
