Option B: 21.3 in is the length of AB

Explanation:

The equation is $\sin 25^{\circ}=\frac{9}{c}$

To find the length of AB, let us equate,

$c=\frac{9}{\sin 25^{\circ}}$

Substituting the value for sin 25°, we get,

$c=\frac{9}{0.4226}}$

Dividing the values, we have

$c=21.3$

Thus, the length of AB is 21.3 in.

The correct answer is Option B.

Delvig [45]

Answer: $\dfrac{33}{40}\ gm$

Step-by-step explanation:

Given

Neville place three weights in the sequence

$\dfrac{1}{2}\ gm,\dfrac{1}{5}\ gm,\dfrac{1}{8}\ gm$

The total weight of the three weights is

$\Rightarrow \dfrac{1}{2}+\dfrac{1}{5}+\dfrac{1}{8}=\dfrac{20+8+5}{40}\\\\\Rightarrow \dfrac{33}{40}\ gm$

Thus, herbs weigh $\frac{33}{40}\ gm$

$18. \ \ \frac{-1}{x-9}- \frac{-2}{x+7}= \frac{-1(x+7)+2(x-9)}{(x-9)(x+7)}= \frac{-x-7+2x-18}{(x-9)(x+7)}= \frac{x-25}{(x-9)(x+7)}$

$\frac{2}{x}+ \frac{12}{x}=7 \\ \\ \frac{14}{x} =7 \\ \\ x= \frac{14}{7} \\ \\ x=2$
