Answer:
MRS. White graded 51 papers.
Step-by-step explanation:
85/100= 0.85
0.85 x 60 = 51
Answer:
v= 3/2
Step-by-step explanation:
multiply cross products which is 9=6v. Then divide by 6 on both sides. Simplify.
Consider the attached figure. If AB has length 1, then BC has length sin(15°) and CD (the altitude of triangle ABC) has length sin(15°)·cos(15°).
By the double angle formula for sin(α), ...
... sin(2α) = 2sin(α)cos(α)
Rearranging, this gives
... sin(α)·cos(α) = sin(2α)/2
We have
... CD = sin(15°)·cos(15°) = sin(2·15°)/2
... CD = sin(30°)/2 = (1/2)/2 = 1/4
That is, the altitude, CD, is 1/4 the hypotenuse, AB, of triangle ABC.
Answer:
That would be C
