Answer:
b. SAS
Step-by-step explanation:
SAS stands for Side Angle Side
The first Side being AB or BC
The Angle being ∡ABD and ∡CBD
And the last Side being BD
Distance between C and D =sr( (-7 - -10)^2 + (6 - 2)^2) = sr(3^2 + 4^2) = sr(9 + 16) = sr(25) = 5 units
We must first solve the number of fiction and nonfiction books
if x is the number of fiction books and
y is the number of nonfinction books
Then,
x + y = 400
x = y + 40
Solving the system of equations:
x = 220
y = 180
Therefore, the probability that Audrey and Ryan will get both nonfiction books is
P = 180/400 + 179/399
P = 0.8986
Answer:
$ 20
Step-by-step explanation:
Given that,
No. of notes Joe has = 4
The total value of the notes = $ 75
From the given notes, 4 notes that can make the sum of 75 would be
$ 50 note + $ 10 + $ 10 note + $ 5
= 50 * 1 + 10 * 1 + 10 * 1 + 5 * 1
= $ 75
Thus, the note that would not be included in the total value would $20 note as if we add it either the sum would be greater or lesser with four notes in combination.
Thhe answer is equal to A. x = 2.5.
