Answer:</h3>
B. 1 : 26
Step-by-step explanation:
Let the volume of large cone, the volume of water and the volume of air in the cone be V,
Vw and Va.
Since the cone of water is similar to the large cone and we know its height is x3 smaller,
Vw = (1/3)^3 * V = V/27
Also, Va = V - Vw
= V - V/27 = 26/27 V
Hence, Vw : Va
1 : 26
Answer:
2, 120 degrees
Step-by-step explanation:
The first step in finding the polar form is finding the modulus, r
r= sqrt( x^2 + y^2)
r = sqrt( (-1)^2 + sqrt(3)^2)
r = sqrt(1+3)
r= sqrt(4)
r =2
The next step is finding the angle
theta = arctan (y/x)
theta = arctan (sqrt(3)/-1))
theta = arctan (-sqrt(3))
theta = -60
The point (-1, sqrt(3)) is in the 2nd quadrant, but our angle is in the 4th quadrant, so we add 180 degrees
theta = -60 + 180 = 120
theta = 120 degrees
Answer:
Copy and paste the question
Step-by-step explanation:
simple
8-8^-1
=8-1/8 <<< 8*8=64 then 64-1=63
=63/8
in decimal(7.875)
6² ÷ 2 × 3 + 4
=36/2(3)+4
=(18)(3)+4
=54+4
=58
