Answer:

AT = 8 $\sqrt{2}$

Step-by-step explanation:

Using the sine ratio in the right triangle

and sin45° = $\frac{1}{\sqrt{2} }$

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{AB}{AT}$ = $\frac{8}{AT}$

Multiply both sides by AT

AT × sin45° = 8, that is

AT × $\frac{1}{\sqrt{2} }$ = 8

Multiply both sides by $\sqrt{2}$

AT = 8 $\sqrt{2}$

Answer:

$\frac{11}{20}$

Step-by-step explanation:

We are told that at the popular restaurant Fire Wok, 55% of guests order the signature dish.

To find the fraction of guests who ordered the signature dish we can write 55% as 55 divided by 100.

$\text{Fraction of guests ordered the signature dish}=\frac{55}{100}$

Upon simplifying our fraction we will get,

$\text{Fraction of guests ordered the signature dish}=\frac{11}{20}$

Therefore, $\frac{11}{20}$ of the guests at the restaurant Fire Wok ordered the signature dish.

For what value of X is the rational expression below equal to zero

ryzh [129]

C. -10

(20+2x)/(5-x)
Multiply both sides by lowest common denominator, simplify
$\frac{(5-x)(20+2x)}{5-x} = (5-x)0$

2x + 20 = 0

2(x + 10) = 0
factor out 2 from 2x+20
