Look at the picture.

Corresponding Angles are equal.

Alternate Angles are equal.

Consecutive Angles add up to 180°.

----------------------------------------------------------------------

3a and 45 are Consecutive Angles. Therefore

3a + 45 = 180    |subtract 45 from both sides

3a = 135      |divide both sides by 3

<h3>a = 45.</h3>

----------------------------------------------------------------------

(2c - 1) and 45 are Corresponding Angles. Therefore

2c - 1 = 45     |add 1 to both sides

2c = 46     |divide both sides by 2

<h3>c = 23.</h3>

----------------------------------------------------------------------

3a and (12b + 3) are Alternate Angles. Therefore

3(45) = 12b + 3

135 = 12b + 3     |subtract 3 from both sides

132 = 12b      |divide both sides by 12

<h3>b = 11.</h3>

The denominator in the earnings per share formula is? a.preferred dividends. b.net income. c.number of preferred shared outstand
astra-53 [7]

The denominator in the earnings per share formula is number of common shares outstanding.

What is the denominator used in the computation of earnings per share?

  • The weighted average of the outstanding shares of common stock serves as the numerator of the earnings per share.
  • The "per share" part necessitates further computation when the number of common shares changes in the middle of the year.
  • The weighting of the per share part depends on how long each share number has been in circulation.

How are basic earnings per share determined?

  • Basic EPS is calculated by dividing net income by the weighted average of the common shares outstanding for the relevant period.
  • Preferred dividends should be removed from the net income because they are not available to common stockholders.
  • Net income can also be broken down into "continuing operations" P&L and "total P&L".

The common ratio of a geometric series is \dfrac14 4 1 ​ start fraction, 1, divided by, 4, end fraction and the sum of the first
myrzilka [38]

Answer:

The common ratio of a geometric series is \dfrac14

4

1 ​

start fraction, 1, divided by, 4, end fraction and the sum of the first 4 terms is 170

The first term is 128

Step-by-step explanation:

The common ratio of the geometric series is given as:

r =  \frac{1}{4}

The sum of the first 4 term is 170.

The sum of first n terms of a geometric sequence is given b;

s_n=\frac{a_1(1-r^n)}{1-r}

common ratio, n=4 and equate to 170.

\frac{a_1(1-( \frac{1}{4} )^4)}{1- \frac{1}{4} } = 170

\frac{a_1(1- \frac{1}{256} )}{ \frac{3}{4} } = 170\\\\ \frac{255}{256} a_1 = \frac{3}{4}  \times 170\\\\\frac{255}{256} a_1 = \frac{255}{2}  \\\\\frac{1}{256} a_1 = \frac{1}{2}  \\\\ a_1 = \frac{1}{2}   \times 256\\\\a_1 = \frac{1}{2}   \times 256 \\\\= 128

a week before election day, 276 out of 450 people said they would vote for the republican candidate. if 15,240 registered voters
Ann [662]

Answer:

(a) \frac {276}{450}=\frac {y}{15240}

(b) We cross multiply the probability by the total voters

(c) 9347

Step-by-step explanation:

(a)

Probability of getting a republican voter is

\frac {276}{450}=\frac {138}{225}=\frac {46}{75}

\frac {276}{450}=\frac {138}{225}=\frac {46}{75}=\frac {y}{15240}

These are found by dividing the first numerator and denominator by 2, then by 3

To make it complete, the situation is therefore defined as \frac {276}{450}=\frac {y}{15240} where y is unknown value

(b)

Cross multiplication of the probability and number of voters gives the actual figure of y in the equation formed in part a of the question.

(c)

Since we have 15240 voters who plan to participate in election, we cross multiply to get the approximate number of republican voters which yields

\frac {46}{75}\times 15240=9347.2\approx 9347

PLEASE HELP ASAP!! DUE!!!
Ipatiy [6.2K]

Answer:

s = (14 + 7 + 11)/2 = 32/2 =16

=> area = sqrt(16*(16-14)*(16-11)*(16-7)) = ~37.95

=> h = 2*Area/Base = 2*37.95/14 = 5.42
