Answer:
D.
Step-by-step explanation:
It just is hard to explain but I had the same question.
Answer:
109.5; B
Step-by-step explanation:
From your identity,
CosA = adjacent/ hypothenus
A represent an arbitrary angle between the sides in question.
In the question above, A=64
Hypothenus is the longest side and adjacent is the side just below the angle .
In the above case,
Hypothenus= X
adjacent =48
This means;
Cos64 = 48 /X
X = 48 / cos64; [ from cross multiplication and diving through by cos64]
X = 48 /0.4383 [ cos64 in radian = 0.4383]
= 109.51
= 109.5 to the nearest tenth.
Note( do your calculation of angle in radian or else, you won't get the answer)
A cone with the same radius and height as a cylinder will have one-third the volume of the cylinder.
Vcone = (1/3)*π*r^2*h
Vcylinder = π*r^2*h
Answer:
60% or 0.6
Step-by-step explanation:
Divide 12 by 20
12/20 = 0.6
Conversion to percentage
0.6 * 100 = 60%
18.39 is 5.58% of 329.64.
We have to find that 18.39 is what percent of 120?
First, make the assumption that 329.64 is 100% as it is our output value.
We next represent the value we seek with x, therefore
100% = 329.64
And, x% = 18.39
Now, we get pair of simple equations
100% = 329.64 ........(1)
x% = 18.39 ........(2)
Now by simply dividing equation 1 by equation 2 and note of the fact that the LHS of both equations have the same unit (%);
100% / x% = 329.64 / 18.39
Taking the reciprocal of both sides, we get
x% / 100% = 18.39 / 329.64
or x = 5.58%
Hence, 18.39 is 5.58% of 329.64.
