Answer:

In order to have the answer, 3.487×10^-5, you have to make the power of 10 into -5 :

7×10^-8 = 0.007×10^-5

e.g.

1×10^-2 = 0.01

1×10^-4 = 0.01×10^-2

(take note: when the power is negative, you have to move to the left)

Then you can solve it :

0.007×10^-5 + 3.48×10^-5

= 10^-5(0.007 + 3.48)

= 10^-5(3.487)

= 3.487×10^-5

How do I solve this ​<br>plz help
svet-max [94.6K]

Well it depends. If your radical is wrapped around the entire expression, then your answer would be 3xy²z²√10xz, but if your radical is ONLY wrapped around 90, then your answer would be 3√10x³y⁴z⁵ [radical wrapped ONLY around 10]. So, with the way this is written, although it is simple to figure this out, it is difficult to find the answer you are looking for.

Robert Masterson bought 99 shares of stock Eddie price of $55 per share and $150 shares at $52 per share. The annual dividend pe
Luda [366]

Answer:

2.39%

Step-by-step explanation:

Given that

99 shares at $55 per share = $5445

150 share at $52 per share = $7800

Hence, total share cost => 5445 + 7800 => $13,245

Therefore, given that the average annual yield is the summation of all the income gotten on investment and dividing the amount by the number of years the money was invested.

With a $1.27 dividend per share, and a total share of 99 + 150 = 249 shares

=> 1.27 * 249 = $316.23

Hence, average annual yield = $316.23 ÷ 13,245

=> 0.0239

=> 2.39%

Therefore, Robert Mastersons' average annual yield is 2.39%
