Which number is irrational? A.0.3 B. C.0.777... D.0.454545…

Savatey [412]

Each of A, C, and D are rational, so presumably B is the answer here.

A is rational, since $10\times0.3=3$ , so $0.3=\dfrac3{10}$ .

C is also rational. If $x=0.777\ldots$ , then $10x=7.777\ldots$ . This would mean $10x-x=9x=7$ , and so $x=\dfrac79$ .

D is rational by a similar argument. If $x=0.4545\ldots$ , then $100x=45.4545\ldots$ . So, $100x-x=99x=45$ , which means $x=\dfrac{45}{99}=\dfrac5{11}$ .

What is the value of x? sin55°=cosx Enter your answer in the box. x = °

rodikova [14]

ANSWER

x=35°

EXPLANATION

The sine and cosine ratio are complementary trigonometric ratios.

This means that:

sin(A)°=cos(90-A)°

The given equation is:

sin(55)°=cos(x).

This implies that,

x=90-55

x=35°

The question is in the picture

Veronika [31]

13 3/4 + x = 7 1/4

becomes x = 13 3/4 / 7 1/4

13 3/4 = 55/4

7 1/4 = 29/4

55/4 / 29/4 = 55/4 * 4/29 = 220/116

220/116 reduces to 1 26/29
