denis23 [38]

Answer:

7.94 x 10⁸miles

Step-by-step explanation:

Given parameters:

Distance of earth from sun = 9.3 x 10⁷miles

Distance of earth from Saturn = 8.87 x 10⁸miles

Unknown:

How much further from the sun is Saturn than Earth = ?

Solution:

To find the solution to this problem, let us find the difference between their distances:

( 8.87 x 10⁸ miles - 9.3 x 10⁷ miles )

= 88.7 x 10⁷ miles - 9.3 x 10⁷ miles

= (88.7 - 9.3) x 10⁷miles

= 79.4 x 10⁷miles

= 7.94 x 10⁸miles

Answer:

$\begin{array}{ccc}\text{Radius}&\text{Volume of sphere}&\text{Volume of cylinder}\\&&\\1&\dfrac{4}{3}\pi &2\pi \\&&\\2&\dfrac{32}{3}\pi &16\pi \\&&\\3&36\pi &54\pi \\&&\\4&\dfrac{256}{3}\pi &128\pi \\&&\\5&\dfrac{500}{3}\pi &250\pi\end{array}$

Step-by-step explanation:

Use formulas for the volumes:

$V_{sphere}=\dfrac{4}{3}\pi r^3,\\ \\V_{cylinder}=\pi r^2h=\pi r^2\cdot 2r=2\pi r^3.$

1. When r=1,

$V_{sphere}=\dfrac{4}{3}\pi\cdot 1^3=\dfrac{4}{3}\pi,\\ \\V_{cylinder}=2\pi \cdot 1^3=2\pi.$

2. When r=2,

$V_{sphere}=\dfrac{4}{3}\pi\cdot 2^3=\dfrac{32}{3}\pi,\\ \\V_{cylinder}=2\pi \cdot 2^3=16\pi.$

3. When r=3,

$V_{sphere}=\dfrac{4}{3}\pi\cdot 3^3=36\pi,\\ \\V_{cylinder}=2\pi \cdot 3^3=54\pi.$

4. When r=4,

$V_{sphere}=\dfrac{4}{3}\pi\cdot 4^3=\dfrac{256}{3}\pi,\\ \\V_{cylinder}=2\pi \cdot 4^3=128\pi.$

5. When r=5,

$V_{sphere}=\dfrac{4}{3}\pi\cdot 5^3=\dfrac{500}{3}\pi,\\ \\V_{cylinder}=2\pi \cdot 5^3=250\pi.$

Note that for all r,

$\dfrac{V_{sphere}}{V_{cylinder}}=\dfrac{\frac{4}{3}\pi r^3}{2\pi r^3}=\dfrac{2}{3}.$

David borrowed $30,000 to start a business. Four years later, he repaid the $30,000 along with an interest of $1,260. What was t

torisob [31]

Answer:

1.05%.

Step-by-step explanation:

If an amount of money, P, called the principal, is borrowed for a period of t years at an annual interest rate r, the amount of interest, I, is given by

I=PrtwhereIPrt=interest=principal=rate=time

The following information is given.

IPt=$1,260=$30,000=4 years

Substituting the given information into the simple interest formula and solving for r gives

I1,2601,260=Prt=(30,000)(r)(4)=120,000r

Dividing both sides by 120,000 and then converting to a percent, we have

r=1,260120,000=0.0105=1.05%

Thus, David's annual interest rate was 1.05%.
