log(x+y)=logx+logy,then x=

Answer»

logx + logy = log(x+y)

log(xy) = log(x+y)

xy = x+y

xy - y = x

(x-1)y = x

y = x/(x-1)

logx + logy = log (x+y)log (xy) = log (x+y)xy =x+yxy-y=x(x-1)y=xy=x/(x-1)

logx + lovy = log (x+y)log (xy) =log (x+y)xy = x+yxy - y = x(x-1)y=xy=x/(x-1)

Rhombus sheet whosepeineيراهل كل القبائل من eینمایی بهم لاand painted on both sales at deste of25 per m bina cost of painting.

Answer»

Perimeter = 4 a = 32 => side = 8mdiagonal c = 10m to find other diagonal d. Then area = c d / 2cost of painting both sides = 2 * (c d / 2) * 5 Rs

In a Rhombus, c² + d² = 4 a² and c² - d² = 4a² cos Ф so d² = 4 * 8² - 10² = 156 d = 2 √39 mCost = 100 √39 Rs.

1. The base area of a cone is 38.5 cm2. Its volume is 77 cm. Find its height.

Answer»

Given:The base area of cone = 38.5 cm^2.Volume of the cone=77cm^3

Thusπr^2=38.5cm2

Vol =13πr^2h=77cm

313*38.5*h=77h=77*338.5=6cmThus height =6cm

A number when added to its half gives 72. Find the number.

Answer»

Let the required number be xHalf of the number = ½x

According to Question = x + ½x = 72 = 2x + x/2 = 72 = 2x+ x = 72×2 = 3x = 144 = x = 144/3 = x = 48

Hence, the required number is 48........
