Mathematics

the price is 0.55$ per square foot

Step-by-step explanation:

We can solve the problem by using the rule of three.

In fact, we know that:

1 gallon covers an area of 100 ft^2

While the price per gallon is

$55 per gallon

This means that the price per 100 ft^2 is $55, since 1 gallon cover 100 ft^2

Therefore, to find the price per square foot, we can write

\frac{55}{100}=\frac{x}{1}

WHere x is the price per square foot. Solving for x,

x=\frac{55}{100}=0.55\$

So, the price is 0.55$ per square foot.

Airline fares for a flight from Dallas to Austin are $30 for first class and $25 for tourist class. If a flight had 52 passenger
posledela

There were 40 tourist class passengers and 12 first class passengers.  

Explanation:

Let the number of passengers who booked for tourist class be

=

x

Then, number of passengers who booked for first class

=

52

−

x

According to question,

Total money paid = $25(tourist class)+$30(first class)

There were 40 tourist class passengers and 12 first class passengers.

Which expression is a difference of squares with a factor of 5x − 8?
Olegator [25]

Answer:

25x^2-64

Step-by-step explanation:

Remember that the formula for the difference of squares is a^2-b^2=(a+b)(a-b). The formula implies that if (5x - 8) is a factor, then (5x + 8) is the other factor. We can use our formula to find which one is our difference of squares:

(5x-8)(5x+8)=(5x)^2-8^2

(5x-8)(5x+8)=5^2x^2-64

(5x-8)(5x+8)=25x^2-64

We can conclude that the correct answer is 25x^2-64.
