Answer:
1 / 8², B
Step-by-step explanation:
8 / 8³
8³ = 8*8*8
So, the equation can also be written as:
8 / 8*8*8
divide the numerator and denominator by 8.
1 / 8*8
This is equal to:
1 / 8²
The answer is B.
Observe that the difference of the sequence is 30. The first term is 12.
Let's use the arithmetic sequence formula
Replacing the given information, we have.
<h2>Hence, the right answer is C because it relates correctly the first term and the difference.</h2>
Try this solution (this is not the only way!):
Q1: if cosx=-0.5 and x∈(90;180), it means x=120°.
So, sin(x-30)=sin(120-30)=sin90°=1.
<u>answer</u>: 1.
Q2: it tgx= -1/√3 and x∈(270°;360°), it means x=330°.
So, sin(x+30)=sin(330+30)=sin360°=0.
<u>answer</u>: 0.
Answer:
Step-by-step explanation:
We are given that the diameter of the sand-shaped cone is 14 inches, and the height is 15 inches.
The volume for a cone is given by:
Where r is the radius and h is the height.
Since the diameter is 14, the radius is 7.
And we are given that the height is 15.
Therefore, the volume will be:
Use a calculator:
The volume of the cone is approximately 769.7 cubic inches.
Step-by-step explanation:
1.2 x 5 = 6.0
0.9 x 1.1 = .99
1.5 x 2 = 3.0
