Tanya bought three adult tickets and one children's ticket to a movie for 24.60 Li bought five adult tickets and four children's tickets for 50.10 . Find the cost of one adult ticket and the cost of one children's ticket.

Answers

Answer:

adult tickets 6.9

children tickets 3.9

Step-by-step explanation:

3x + y = 24.60 L1

5x + 4y = 50.10 L2

5L1 - 3L2

15x + 5y = 123

-15x - 12y = -150.3

-7y = -27,3

y = -27,3/-7

y = 3.9

3x + y = 24.60

3x + 3.9 = 24.60

3x = 24.60 - 3.9

3x = 20.7

x = 20.7 / 3

x = 6.9

Find the value of 3/27

Answers

Answer:

The cubed root of a number is the number that, when multiplied by itself three times (number x number x number), gives the original number. For example, the cubed root of 27 is 3, as 3 x 3 x 3 = 27. The cubed root of 125 is 5, as 5 x 5 x 5 = 125. Unlike the square root, the cubed root is always positive

A metal washer is made by cutting out a circle 13.2 mm in diameter from a larger circle. To the nearest tenth, what is the area of the washer

Answers

The standard formula of area of the circle is (pi * r^2)
here r is radius.

So the radius of this washer is equal to 6.1 mm (13.2 / 2)
Therefore the area of the washer
pi * 6.1^2
116.9 mm^2

When evaluating proportions, we write the ratios in fractional form and then we
