Write 0.7--- as a fraction.

its 7/10

Step-by-step explanation:

In 0.7 we will change the decimal to fraction.

First we will write the decimal without the decimal point as the numerator.

Now in the denominator, write 1 followed by one zeros as there are 1 digit in the decimal part of the decimal number.

= 7/10

Therefore, we observe that 0.7 (decimal) is converted to 7/10 (fraction).

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
