Answer:
B) 17 games.
Step-by-step explanation:
Let <em>g</em> represent the number of games Mark played.
Since there is a $5 entrance fee and each game costs an additional $1.25, we can write the expression:

Which represents that total cost after <em>g</em> games.
Since we know that Mark spent a total of $26.25:

Solve for <em>g.</em> Subtract five from both sides:

And divide both sides by 1.25. Hence:

So, Mark played a total of 17 games.
Our answer is B.
Answer:
The length of a rectangle is 2 feet more than it's width. How do you find the dimensions of the rectangle if its area is 63 square feet?
Step-by-step explanation:
x(x+2) = 63
x^2 + 2x = 63
x^2 + 2x - 63 = 0
Quadratic formula with numbers plugged in: (-2 +or- sqrt(4 - 4* 1 * -63))/2 becomes
-2 +or- sqrt(256)/2 so (-2 +or- 16)/2 therefore -18/2 or 14/2. Discard negative result.
x = 7. 63/7=9. Sides are 7ft and 9ft.
Answer:
110sin(72°) feet
Step-by-step explanation:
In the right triangle with the 110 ft ladder as the hypotenuse, the side opposite the 72° angle represents the maximum height the ladder will reach. The definition of the sine function tells you ...
Sin = Opposite/Hypotenuse
so the Opposite side will be ...
ladder height = (110 ft)sin(72°)
