A construction worker needs to raise some materials to the top of a 20-ft tall building by using a computer-controlled crane. If the materials are 28 feet away from the base of the building, what slope needs to be programmed into the computer to accomplish the delivery? State your answer as a fraction in lowest terms
The stack on the left is made up of 15 pennies, and the stack on the right is also made up of 15 pennies. If the volume of the stack of pennies on the left is 390 mm3, what is the volume of the stack of pennies on the right in cubic millimeters? (Hint: only enter numerals in the answer blank) (4 points)

The drawing below shows a right-angled triangle. A straight line crosses the triangle parallel to
the line z and encloses an angle of α. The lengths x and y of the bottom and top line segments
as well as the angle α are given. Find an equation for the length z.
A circle has an area equal to 25pi cm2. Its diameter AB coincides with one of the sides of triangle ACB whose vertex C lies on the circle. If the triangle has an area equal to 11 cm2, find the perimeter of the triangle.
Point M lies on side AC of an equilateral triangle ABC; circles \Omega _1 and \Omega _2 are circumcircles of triangles MAB and MBC respectively. It is known that point A divides arc MAB of circle in the ratio of \Omega _1 that MA:AB = 28:41. Find the ratio on which point C devides arc MCB of circle \Omega _2 . In the answer indicate MC:CB
If the circle passing through the point (-1,0) touches the y-axis at (0,2) then what is the equation of the circle?
