In the figure shown, ABCD is a square and triangle CDE is equilateral. What is the degree measure of angle CBE?
ElenaW [278]

Answer:

angle CBE=15 degrees

Step-by-step explanation:

angle ECD is 60 degrees and EC=CD because equilateral triangle

angle DCB is 90 degrees and CB=CD because square

angle ECD +angle DCB= angle ECB

60+90=150=angle ECB

since triangle ECB has legs EC and CB  equal in length, then it is an isosceles triangle.

so angles CBB and CBE are equal

angle CBE=(180-150)/2

angle CBE=15 degrees

Stockholders' Equity Paid-In Capital: Common Stock, $120 Par (500,000 Shares Authorized, 400,000 Shares Issued) $ Excess over pa
Mashutka [201]

Answer:

$117,380,000

Step-by-step explanation:

Stockholders' Equity section of the balance sheet

Paid in capital:

common stock $120 Par (500,000 Shares Authorized, 400,000 Shares Issued)    = $120  * 400,000 = $48,000,000

Excess over par = $6,400,000

Paid in capital, common stock = $48,000,000 + $6,400,000 =$54,400,000

From sale of treasury stock =  $4,500,000

Sum total paid-in capital = $54,400,000 + $4,500,000 = $58,900,000

Retained earnings =$63,680,000

Treasury stock (40,000 shares at cost) = $5,200,000

Total stockholders’ equity =$58,900,000 + $63,680,000 - $5,200,000

= $117,380,000

Find f(x) · g(x) = (fg)(x). Simplify. f(x) = x2 + 4 g(x) = x2 − x + 5
9966 [12]
<span>f(x) = x2 + 4 g(x) = x2 − x + 5

</span>f(x) · g(x) = (fg)(x) = (x^2 + 4)(<span> x^2 − x + 5)
</span>f(x) · g(x) = (fg)(x) = x^4 - x^3 + 5x^2 + 4x^2 - 4x + 20
f(x) · g(x) = (fg)(x) = x^4 - x^3 + 9x^2 - 4x + 20

answer
f(x) · g(x) = (fg)(x) = 
x^4 - x^3 + 9x^2 - 4x + 20

7+3/5b=7/10b what is b
Olegator [25]

Answer:

b = 70

Step-by-step explanation:

7+3/5b=7/10b

Subtract 3/5 b from each side

7+3/5b - 3/5 b=7/10b - 3/5 b

7 = 7/10 b - 3/5 b

We need to get a common denominator or 10 on the right hand side

7 = 7/10 b -3/5 *2/2 b

7 = 7/10b - 6/10 b

7 = 1/10 b

Multiply each side by 10

7*10 = 1/10 * 10 b

70 = b
