Step-by-step explanation:
SinA=1/3=p/h
p=1,h=3,and b=?
Using Pythagoras Theorem,
b=√3^2-1^2
b=√9-1
b=√8=2√2
Now,
CosA=b/h=2√2/3
TanA=p/b=1/2√2
There is no phi in my keypad so I use A angle instead of phi.Adjust it.

Answer:
d = 1.1 units
Step-by-step explanation:
Since the x- coordinates of the 2 points are equal, both 3, then they lie on a vertical line. The distance between the 2 points is the difference in the y- coordinates, that is
d = | 2.4 - 1.3 | = | 1.1 | = 1.1 units
If you miss 9 questions, the how many did you get right?
85 - 9 = 76
So now you got 76 out of 85 correct or 76/85...
Now if you just do the fractional division that is described by the fraction you will get the answer. The fraction bar literally means "divided by", so the fraction means...
76 divided by 85 which equals...
.8941
Now to convert to percentage we multiply by 100 (move the decimal 2 places to the right)
.8941 x 100 = 89.41% Round to nearest one percent...
89%
Answer:
B. 7/30
Step-by-step explanation:
1st time to pick red is 8/16 8 red cubes out of 16 are red
2nd time to pick red is 7/15 7 red cubes out of 15 are red,
*if one red is picked already
8/16 x 7/15 = 7/30
