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
Boxes 1-4 met the goal. Only #5 did not meet the goal.
so 4 boxes.
Look at the pictures (examples)
m∠1 = m∠6 → answer: none
m∠2 = m∠3 → answer: none
m∠2 = m∠C → answer: none
7 tens and 3 ones would equal 73... 7×10+3×1=73
Answer:
39°
Step-by-step explanation:
A radius of a circle (segment CD) drawn to the point of tangency (D) intersects the tangent (line DE) at a 90-deg angle.
That makes m<D = 90.
m<D + m<C + m<E = 180
90 + 51 + m<E = 180
m<E = 39
