80% of what # is 16?

1 answer:

4 0

80% of x = 16
"of" translates to multiplication and 80% becomes 80/100.

80/100 × x = 16

0.8x = 16

0.8x/0.8 = 16/0.8

x = 16/0.8

x = 20

Your final answer is 80% of 20 is 16.

Given sin z=4/5 and cos x=3/5. What is the ratio for tan z? Enter your answer in the boxes as a fraction in simplest form.

Minchanka [31]

The answer is: " $\frac{4}{3}$ " .
______________________________________________________
Explanation:
______________________________________________________
Note: tan z = (sin z/ cos z) ;

tan z = (4/5) / (3/5) ;

= $\frac{4}{5}$ * $\frac{5}{3}$ ; 
Note: Both of the "5 ' s" cancel out to "1" ; since: "{5 ÷ 5 = 1 }" ;

And we rewrite as:

→ " $\frac{4}{1}$ * $\frac{1}{3}$ " ;

= $\frac{(4*1)}{(1*3)}$ ;

= " $\frac{4}{3}$ " .

The answer is: " $\frac{4}{3}$ " .
