D) If C.P. - Rs 100, S.P. Rs 80, then loss percent

AfilCa [17]

Step-by-step explanation:

Selling price = Rs.80

Cost price = Rs.100

here, CP > SP

Now...

Loss ( L ) = CP - SP

= RS.100 - 80

= Rs.20

Now...

$loss \: percent \: = \frac{loss}{CP} \times 100%$

$= \frac{2000}{100} \\$

= 20 %

For what values of x is the following expression a real number?<br> <img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20-4" id="

IrinaVladis [17]

The square root is defined only for non-negative numbers. In other words, you can compute $\sqrt{x}$ if and only if $x \geq 0$

If $x \geq 0$ , the square root is a real number, and so is $\sqrt{x}-4$

Jack is at the zoo looking up at a monkey

sasho [114]

The height of the pole at which the monkey is at the top is 10.2 feet.

<h3>Trigonometric ratio</h3>

Trigonometric ratio is used to show the relationship between the angles and sides of a right angled triangle.

Let h represent the height of the pole, hence using trigonometric ratio:

tan(23) = h/24

h = 10.2 feet

The height of the pole at which the monkey is at the top is 10.2 feet.
