Answer:
There are 14 new books and 22 old books in the package.
Step-by-step explanation:
New books cost $20 and used books cost $8. The bookstore wants to sell packages that have 36 books total, and the store charges $456 for each package.
If the number of new books in the package is x and that of old books in the package is y, then we can write two simultaneous equations as
x + y = 36 ........... (1) and
20x + 8y = 456
⇒ 5x + 2y = 114 ............ (2)
Now, solving equations (1) and (2) we get,
5x + 2(36 - x) = 114
⇒ 3x + 72 = 114
⇒ 3x = 42
⇒ x = 14
Then, y = 36 - x = 22.
Therefore, there are 14 new books and 22 old books in the package. (Answer)
Answer:
mMKL = 115°
Step-by-step explanation:
Using the property of intersecting chords in a circle, we have that one angle in the intersecting point is the average of the arcs intercepted by the angle and its vertical angle.
So, to find the measure of the angle MKL, we have:
mMKL = (1/2) * (mML + mNU)
mMKL = (1/2) * (155 + 75)
mMKL = (1/2) * (230)
mMKL = 115°
