Lucy fills a bathroom sink with water. Is the amount of water more than 1 liter, about 1 liter or less than 1 liter? Explain how
Novay_Z [31]
Proposed Answer
Much more than 1 liter.

Make a guess.
Suppose the bathroom sink is about 15 inches across. That's actually not very big for a bathroom sink. But it makes up for the other estimate I'm going to make. 

Suppose the sink is 7 1/2 inches deep at it's deepest point. So what you have is a 1/2 sphere. Figure this out in ccs. That way you have a simple conversion to make.

Conversion
1 in = 2.54 cm
7 1/2 in = x       Cross multiply

x * 1 inch= 7 1/2 * 2.54
x  =  6.5 * 2.54
x = 19.05 cm

x is actually the radius of the 1/2 sphere.
pi = 3.14
r = x = 19.05 cm

V = (4/3) pi * 19.05^3 / 2
V =  86831 / 6
V = 14471 ccs

1 L = 1000 cc
x  =    14471 cc

x = 14.471 Liters. That's 14.5 times bigger than 1 Liter. Most sinks are about 7 1/2 inches deep but they are more across than 15 inches. So my answer is much  more than 1 Liter.  <<<<< Answer

Answer much more than a liter.

Modern computers are built using the principle of Hierarchical layers of abstraction. Explain Hierarchical layers of abstraction
bearhunter [10]

Answer:

Hierarchical layers of abstraction in computers are used to hide information and manage deep functionality by allowing the separation to facilitate  platform independence.

Step-by-step explanation:

Hierarchical layers of abstraction in computers:

Hierarchical layers of abstraction in computers are used to hide information and manage deep functionality by allowing the separation to facilitate  platform independence.

In Hierarchical layers, users work independently at each level of the hierarchy.

example:

Abstraction in computing is language abstraction

Development of programming languages from machine language to  assembly language and then high-level language is an example of  Hierarchical layers of abstraction. Here each stage is a base for the next stage.

Write the General Form of the equation of the circle centered at (1, 2) with radius 3. PLZZZZZZZZZZZZZ Help
docker41 [41]

Answer:

X^2 +Y^2 - 2X-4Y= 0

Step-by-step explanation:

From the circle eqn.

(x-a) ^2 +(y-b) ^2 =r^2

a=1, b= 2. r= 3

(x-1)^2 +(y-2)^2 =3^2

(x-1)(x-1)+(y-2)(y-2)=3^2

X^2 - 2x+1+y^2 -4y+4=9

X^2 +Y^2 - 2x-4y+5=9

X^2 +Y^2 - 2x-4y-4=0
