495 is 55 percent of what number
Delicious77 [7]
If you would like to know 55 percent of what number is 495, you can calculate this using the following steps:

55% of what number = 495
55% * x = 495
55/100 * x = 495
x = 495 * 100/55
x = 900

The number you are looking for is 900.

Simplify the sum. d^2-7d+12/d^2-d-6 + d^2+5d+6/d^2-2d-15
Law Incorporation [45]

Answer:

The sum is \frac{2d^2-5d+24}{d^2-3d-10}

Step-by-step explanation:

The given expression is


\frac{d^2-7d+12}{d^2-d-6}+\frac{d^2+5d+6}{d^2-2d-15}


These are all quadratic trinomials, so we split each of the middle terms to obtain,

\frac{d^2-4d-3d+12}{d^2-3d+2d-6}+\frac{d^2+2d+3d+6}{d^2-5d+3d-15}


We factor to obtain,


\frac{d(d-4)-3(d-4)}{d(d-3)+2(d-3)}+\frac{d(d+2)+3(d+2)}{d(d-5)+3(d-5)}


We factor further to obtain,

\frac{(d-4)(d-3)}{(d-3)(d+2)}+\frac{(d+2)(d+3)}{(d-5)(d+3)}


We cancel out the common factors to get,


\frac{(d-4)}{(d+2)}+\frac{(d+2)}{(d-5)}


The least common denominator is (d+2)(d-5).


We collect LCD to get


\frac{(d-4)(d-5)+(d+2)(d+2)}{(d+2)(d-5)}


We now expand to get,


\frac{d^2-5d-4d+20+d^2+2d+2d+4}{d^2-5d+2d-10}


We simplify to get,


\frac{d^2-9d+20+d^2+4d+4}{d^2-3d-10}


We simplify further to get,


\frac{2d^2-5d+24}{d^2-3d-10}

GAMES In a game of pick-up-sticks, the last 4 sticks
Nimfa-mama [501]

Answer:

∠1 and ∠2

∠3 and ∠4

∠5 and ∠6

Step-by-step explanation:

The question figure is shown below.

To find the angles which are supplementary angles.

Solution:

Supplementary angles are a pair of angles that lie on a straight line and hence the sum of the angle = 180°

In the figure shown below, there are three pairs of angles that lie on a straight line.

The pairs are:

∠1 and ∠2

∠3 and ∠4

∠5 and ∠6

Since all the three pairs of angles lie on a straight line, hence the pairs are called linear pairs or supplementary angles.
