Alvin is 14 years older than Elga. The sum of their ages is 56. What is Elga's age?

Mathematics

uysha [10]3 years ago

Answer:

Elga is 32 years old.

Step-by-step explanation:

Let Alvin's age = A

Let Elga's age = E

 

Alvin is 10 years younger than Elga, so A = E - 10

The sum of their ages is 54, so A + E = 54

 

Replace the A in the second equation with E - 10, then solve for E.

A + E = 54 becomes (E - 10) + E = 54

 

Combine like terms

2E - 10 = 54

 

Add 10 to both sides

2E = 64

 

Divide both sides by 2

E = 32

ollegr [7]

Answer:

The contribution margin it's determined by the total amount of Gross Profit divided by the total value of sales.

Profit = $405,000

Sales = 11,250×106 =$1,192,500

Therefore contribution margin ratio = ($405,000/$1,192,500) = 0.34

The Break Even point is given thus;

Fixed cost = 25 × 11250 =$281,250

Break-even point = Fixed costs ÷ contribution ratio

= $281,250/0.34 = $827,205.88

use a^2-b^2=(a+b)(a-b)

to get (\cos^3A-\sin^3A)(\cos^3A+\sin^3A)

then use a^3+b^3=(a+b)(a^2+b^2-ab)

and a^3-b^3=(a-b)(a^2+b^2+ab)

also, \sin^2\theta+\cos^2\theta=1

to get (\cos A-\sin A)(1+\sin A\cos A)(\cos A+ \sin A)(1-\sin A\cos A)

then again use the first identity In both pairs, i.e.

(\cos A-\sin A)(\cos A+ \sin A) \cdot (1+\sin A\cos A)(1-\sin A\cos A)

to get \cos 2A (1-\sin^2A\cos^2A)

multiply and divide by 4 to get the RHS.

because, \sin(2A)= 2\sin A \cos A

squaring both sides, \sin^2 (2A)=4\sin^2A\cos^2A
