The area of a parallelogram is base X height.
so here will be 20 x h = 300
therefore the height is 15
Answer: the rate of the water level in the cone falling when it is 5cm from the bottom of the cone is -0.1768 cm/sec
Step-by-step explanation:
Given the data in the question;
H/h = R/r
10/5 = 6/r
r 1 = 30/10 = 3
Also
10/h = 6/r
r2 = 6h/10 = 3/5 × h
Volume = 1/3πr²h
V = 1/3 × π × (3/5 × h)² × h
V = 1/3 × π × 9/25 × h³
V = 3π/25 × h³
Now
dv/dt = 3π/25 × 3 × h² × dh/dt
-5 = 3π/25 × 3 × 25 × dh/dt
-5 = 3π × 3 × dh/dt
-5 = 9π × dh/dt
dh/dt = -5/9π
dh/dt = -0.1768 cm/sec
therefore, the rate of the water level in the cone falling when it is 5cm from the bottom of the cone is -0.1768 cm/sec
Answer:
From the given data:
More than half of the students own the least number of red dresses, so the data is positively skewed (skewed to the right).
As the number of red dresses owned increases, the number of students owning this number of red dresses generally decreases.
Answer:
A= x=-4
B= x=4
C= y=4
D= y=-2
Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
Interior angles and their exterior angles make a supplementary angle meaning they have a sum of 180°. Knowing this, we can make an equation to solve for x.
x + 165 = 180
x = 15
