Answer:

Perimeter of MNO = 38.71 in.

Area of MNO = 63.73 sq. in.

Step-by-step explanation:

Since the two triangles are similar, this means that

- linear dimensions are proportional to ratio of corresponding sides

- areas are proportional to ratio of corresponding sides.

Ratio of corresponding sides of MNO to DEF

= 6.7/9

Therefore

Perimeter of MNO = P*6.7/9 = 38.71 in.

Area of MNO = A*(6.7/9)^2 = 63.73 sq. in.

The product of 2 numbers is when you multiply them together. 12x2=24

The quotient of 2 numbers is when you divide them. 45/5=9

The total number of people at a football game was 5600. Field-side tickets were 40 dollars and end-zone tickets were 20 dollars.

rewona [7]

Answer:

1100 field-side tickets and 4500 end-zone tickets.

Step-by-step explanation:

Let x represent number of field side tickets and y represent number of end-zone tickets.

We have been given that the total number of people at a football game was 5600. We can represent this information in an equation as:

$x+y=5600...(1)$

$y=5600-x...(1)$

We are also told that Field-side tickets were 40 dollars and end-zone tickets were 20 dollars.

Cost of x field side tickets would be $40x$ and cost of y end-zone tickets would be $20y$ .

The total amount of money received for the tickets was $134000. We can represent this information in an equation as:

$40x+20y=134000...(2)$

Upon substituting equation (1) in equation (2), we will get:

$40x+20(5600-x)=134000$

$40x+112000-20x=134000$

$20x+112000=134000$

$20x+112000-112000=134000-112000$

$20x=22000$

$\frac{20x}{20}=\frac{22000}{20}$

$x=1100$

Therefore, 1100 field side tickets were sold.

Upon substituting $x=1100$ in equation (1), we will get:

$y=5600-1100$

$y=4500$

Therefore, 4500 end-zone tickets were sold.

The dimensions of a 10 ft by 6 ft rectangle are multiplied by 1/3. how is the area affected?

Misha Larkins [42]

Area is proportional to the square of the dimensions. Divide the dimensions by 3, and you divide the area by 3-squared = 9.
