Answer:

4,000 L/h

Step-by-step explanation:

First we'll find the amount of the change.

18,000 - 6,000 = 12,000 L

The time of the volume change was 3 hours: 0230 - 0530

Since we're looking for liters per hour, we will divide the liters (12,000) by the hours (3)

12,000/3 = 4,000 L/h

There are two spheres of different sizes. The large sphere has a radius 3 times the size of the small sphere. How many times lar
Vikentia [17]

Answer:

The answer to your question is the letter B. 27

Step-by-step explanation:

Data

The Radius of large sphere = 3 times the size of the radius small sphere.

The Ratio of Volume = ?

Formula

Volume of a sphere = 4/3 πr³

Process

1.- Calculate the volume of the large sphere

                   Vl = 4/3 π(3r)³

2.- Calculate the volume of the small sphere

                   Vs = 4/3 πr³

3.- Calculate the ratio

                   Vl / Vs = [4/3π(3r³)] / [4/3 πr³]

- Simplification

                   Vl / Vs = 3³r³ / r³

                   Vl / Vs = 27

bezimeni [28]

Answer:

smaller x =-1/2

larger x = 7

Step-by-step explanation:

(x-7)(-4x - 2) = 0

Using the zero product property

(x-7)=0              (-4x - 2) = 0

x-7+7 = 0+7        -4x-2-2 =0+2

x=7                         -4x =2

                               -4x/-4 = 2/-4

                                    x = -1/2

mina [271]

Answer:

67.20\%

Step-by-step explanation:

Given

n =2430 --- sample

r = 16.72\% --- degeneration rate

From the findings, we have:

p = 377 --- tested positive

t =561 --- total test

Required

The positive predicted value (PPV)

This is calculated using:

PPV=\frac{Positive}{Total}

i.e.

PPV = \frac{377}{561}

PPV = 0.6720

Express as percentage

PPV = 0.6720 * 100\%

PPV = 67.20
