Generally what do the elements in a group have in common with each other?

1 answer:

6 0

They have the same number of valence electrons which, in general, gives them similar oxidation numbers and other similar chemical and physical properties. The similarities are most pronounced in the groups at either side of the standard periodic table, and are least pronounced for the transition and rare earth elements.

Rodrigo planted flowers in a section of a circular garden as shown. Calculate the closest area of this sector of the garden to t

Novay_Z [31]

Answer:

$A = 118ft^2$

Step-by-step explanation:

See attachment for complete question.

From the attachment, we have:

$\theta = 80$

$r = 13ft$ -- Radius

Required

Determine the area of the sector

Area (A) of a sector is calculated as:

$A = \frac{\theta}{360} * \pi r^2$

Substitute values for r and $\theta$

$A = \frac{80}{360} * \pi 13^2$

$A = \frac{80}{360} * \pi *169$

$A = \frac{80*169}{360} * \pi$

$A = \frac{13520}{360} * \pi$

Take $\pi$ as $\frac{22}{7}$

$A = \frac{13520}{360} * \frac{22}{7}$

$A = \frac{13520 * 22}{360 * 7}$

$A = \frac{297440}{2520}$

$A = 118ft^2$ <em>-- approximated</em>

Anastaziya [24]

The amount reported for the investment in Zip Company by Akron's December 31, 2021, balance sheet is <u>$143,400</u>, which is the fair value of the Common Stock of Zip Company.

<h3>What is the fair value of an investment?</h3>

The fair value of an investment is the current value and not the historical cost when the investment was made.

Fair value refers to the intrinsic worth of an asset or security.

<h3>Data and Calculations:</h3>

Income Dividends Common Stock Akron's Investment

Declared Fair Value (12/31) in Zip Company

2019 $321,000 $16,050 ($321,000 x 5%)

2020 $79,000 $6,200 376,000 $94,000 ($376,000 x 25%)

2021 89,000 15,800 478,000 $143,400 ($478,000 x 30%)

Excess attributed to share of Zip's franchises = $33,350 ($143,400 - $110,050).

Thus, the amount reported for the investment in Zip Company by Akron's December 31, 2021, balance sheet is <u>$143,400.</u>
