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:

1.25g+5

Which represents that total cost after <em>g</em> games.

Since we know that Mark spent a total of $26.25:

1.25g+5=26.25

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

1.25g=21.25

And divide both sides by 1.25. Hence:

g=17

So, Mark played a total of 17 games.

Our answer is B.

TiliK225 [7]

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.

Svetradugi [14.3K]

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°)
