Bezzdna [24]

Answer:

The answer is "0.03125".

Step-by-step explanation:

Two types of undergraduates exist. Its chance for selecting the very first person who is part of degree studies will be 1/2. The probability will also be 1/2 for the 2nd person, as well as, the 3rd, 4th, and 5th person. For 5 random samples, the probability of the graduate therefore is

\to \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} =  \frac{1}{32}=0.03125

You are build a water tower. The scale factor is 1 : 12. The model depth is 32 centimeters. What is the actual depth in meters?&
Mkey [24]
Scale Factor = 1 : 12

It means, for every 12 centimeters, it is 1 centimeter in the model

The depth of Tower in model = 32 cm
In real, It would be: 32 * 12 = 384 cm

We know, 1 m = 100 cm
So, 384 cm = 384/100 = 3.84 m

In short, Your Answer would be: 3.84 meter

Hope this helps!

Rewrite the formula to solve for the positive value of r in terms of h and v.
Zigmanuir [339]

Answer:

r=\sqrt{\dfrac{3V}{\pi h}}

Step-by-step explanation:

The formula for the volume of a cone is given by :

V=\dfrac{1}{3}\pi r^2 h

Where

r is radius of cone and h is its height

We need to solve the above formula for r.

Cross multiplying both sides of the given formula

3V=\pi r^ 2h

Dividing both sides by πh.

\dfrac{3V}{\pi h}=\dfrac{\pi r^2 h}{\pi h}\\\\r^2=\dfrac{3V}{\pi h}\\\\r=\sqrt{\dfrac{3V}{\pi h}}

So, the formula for r is \sqrt{\dfrac{3V}{\pi h}}
