Answer:

By summing cylindrical slabs of infinitesimal height and different radii place one on the other such that margin of between real and intended volume is minimum.

Step-by-step explanation:

A spherical slab is characterized by the radius as its inherent variable and cylindrical slabs by its radius and height. The volume of the spherical slab can be approximated by summing cylindrical slabs of infinitesimal height and different radii place one on the other such that margin of between real and intended volume is minimum.

Answer:

OC=48

RK=100

Step-by-step explanation:

We can use proportions to find both OC and RK.

$\frac{OK}{KY} =\frac{OC}{RY}$

$\frac{12}{24} =\frac{OC}{96}$

$24OC=1152$

$OC=48$

$\frac{KC}{RK} =\frac{OK}{KY}$

$\frac{50}{RK} =\frac{12}{24}$

$12RK=1200$

$RK=100$

$56,820 rounded to the nearest dollar

Alex_Xolod [135]

Well, if that is a comma in the number, it is already rounded. If the comma is supposed to be a decimal, the answer would be $57.

What is the solution to the system of equations below? -4x+6y=-18 and y=-2x+21

Verdich [7]

Answer:

x=9 and y=3

Step-by-step explanation:

Let's solve your system by substitution.

−4x+6y=−18 and y=−2x+21

Rewrite equations:

y=−2x+21;−4x+6y=−18

Step: Solve y=−2x+21for y:

y=−2x+21

Step: Substitute−2x+21foryin−4x+6y=−18:

−4x+6y=−18

−4x+6(−2x+21)=−18

−16x+126=−18(Simplify both sides of the equation)

−16x+126+−126=−18+−126(Add -126 to both sides)

−16x=−144

−16x

−16

−144

−16

(Divide both sides by -16)

x=9

Step: Substitute9forxiny=−2x+21:

y=−2x+21

y=(−2)(9)+21

y=3(Simplify both sides of the equation)

Answer:

x=9 and y=3

3. A savings account has a 3% interest rate. (a) Complete the ratio table shown. Show your work. Deposit ($) 100 50 300 Interest

blsea [12.9K]

We all know, savings account have "Compound Interest"

So, Here, On $100 deposit, amount of Interest = $12

So, for $50, it would be: $6

Then, for $300, it is: $36

b) If you deposit $200, then balance after 1 year,
A = P(1 + r)^t

A = 200(1 + 0.03)^1

A = 200(1.03)
A = $206

Now, Balance with $150
A = 150 (1 + 0.03)^1
A = 150(1.03)
A = 154.5

Difference = 206 - 154.5 = $51.5

In short, Your Answer would be: $51.5

Hope this helps!
