<em>first:</em>

<em></em> $\left(\frac{1}{4}+1\frac{1}{2}\right)\cdot \frac{1}{2} =\left(\frac{1}{4}+\frac{3}{2}\right)\cdot \frac{1}{2} =\frac{\left(\frac{1}{4}+\frac{3}{2}\right)\cdot \:1}{2} =\frac{\left(\frac{1}{4}+\frac{6}{4}\right)\cdot \:1}{2} =\frac{\frac{7}{4}\cdot \:1}{2} =\frac{\frac{7}{4}}{2} =\frac{7}{4\cdot \:2} =\frac{7}{8}$ <em></em>

Hannah earned $1536 in 8 years on an investment at a 4% annual simple interest rate. How much was Hannah’s investment? $4800 $30

Nonamiya [84]

Simple interest calculates interest on initial amount only. The investment by Hannah was : Option A: $4800

<h3>How to calculate simple interest amount if rate of interest is R% annually?</h3>

Suppose that the initial amount of investment is P

And the rate of simple interest is R% annually,

And the time of investment is T years.

Then, the amount of simple interest is calculated as:

$I = \dfrac{P \times R \times T}{100}$

For the given case, let the initial investment Hannah made was of $P

Then, the time of investment is T = 8 years, R% = 4%, and given that Hannah earned interest I = $1536

Putting values in the above formula, we get;

$I = \dfrac{P \times R \times T}{100}\\\\1536 = \dfrac{P \times 8 \times 4}{100}\\\\P = \dfrac{153600}{32} = 4800$

Thus,

The investment by Hannah was : Option A: $4800

The mean distance from the Sun to Earth is 9.29x10^7. Jupiter’s mean distance from the Sun is 4.8388x10^8. What is the differenc

iVinArrow [24]

Answer:

$-3.9098*10^8$

Step-by-step explanation:

1) Convert to Standard Form:

9.29 * 10^7 = 92900000

4.8388 * 10^8= 483880000

2) Subtract 483880000 from 92900000.

$92900000-483880000=-390980000$

3) Convert the difference into scientific notation.

$-390980000= -3.9098 * 10^8$

<em>C would be your best choice.</em>
