Rina8888 [55]

Answer:

Number of Fares to airport is 25 and number of fares from airport is 25.

Step-by-step explanation:

Given:

Total Number of fares =50

Let number of fares to airport be x.

Let number of fares from airport be y.

hence the equation can be framed as;

$x+y=50 \ \ \ \ equation \ 1$

Also Given

Total Money Collected = $375

Cost to airport = $10

Cost from Airport = $5

Total Money Collect is equal to Cost to airport multiplied by number of Fares to airport plus Cost from airport multiplied by number of Fare from airport.

$10x+5y=375$

Dividing by 5 on both side we get;

$2x+y = 75 \ \ \ \ equation \ 2$

Now Subtracting equation 1 from 2 we get;

$(2x+y)-(x+y)=75-50\\2x+y-x-y=25\\x=25$

Substituting the value of x in equation 1 we get;

$x+y=50\\25+y=50\\y=50-25\\y=25$

Hence Number of Fares to airport is 25 and number of fares from airport is 25.

The screen at Dallas' AT&T Stadium is 175 feet wide. A movie theatre screen with

Mazyrski [523]

Answer:

17150 ft²

Step-by-step explanation:

Given the ratio of sides = a : b , then

ratio of areas = a² : b²

Here ratio of sides = 175 : 40 = 35 : 8 , then

ratio of areas = 35² : 8² = 1225 : 64

let x be the area of AT & T Stadium then by proportion

$\frac{x}{1225}$ = $\frac{896}{64}$ ( cross- multiply )

64x = 896 × 1225 = 1097600 ( divide both sides by 64 )

x = 17150

The AT & T screen has an area of 17150 ft²
