The answer is:
________________________________________________________
" $\frac{4829}{900}$ "; or, "5 $\frac{329}{900}$ " ;
or, write as: "5.366" .
________________________________________________________
Explanation:
__________________________________
Given: " (1 + 0.12 ÷ 12)12 * 1 ÷ 2− 1 ÷ 0.12 ÷ 12 = ? " ;
___________________________________________

First, start with the "parentheses" ;
______________________________
"(1 + 0.12 ÷ 12) = ??

Start with the division: " 0.12 ÷ 12 = 0.01 " .

"(1 + 0.01)" = (1.01) .

We have: "1.01 (12)
Given: " (1.01)12 * 1 ÷ 2 − 1 ÷ 0.12 ÷ 12 = ? " ;

So, 1.01 * 12 = 12 .12 .
______________________
" 12.12 * 1 ÷  2 − 1 ÷ 0.12 ÷ 12 = ? " ;

Note: Using order of operations, treat this problem as:

" [ (12.12 * 1) ÷  2 ] − [ (1 ÷ 0.12) ÷ 12 ] = ? " ;

→ ( 12.12 ÷ 2 ) − (25/3) ÷ 12 ] = ? " ;

→ ( 6.06) − { (25/3) * 1/12) } = ?

→ ( 6.06) − { ( 25* 1) / (3*12) = ?

→ ( 6.06) − { ( 25* 1) / (3*12) = ?

→ ( 6.06) − (25/36) ;

→ 6 $\frac{6}{100}$ − $\frac{25}{36}$   ;

→ 6 $\frac{3}{50}$ − $\frac{25}{36}$   ;

Rewrite " 6 $\frac{3}{50}$ " ; as an improper fraction:

→ " 6 $\frac{3}{50}$ " = "[ (50*6) + 3 ] / 50 = $\frac{303}{50}$ ;
__________________________________________
→ 6 $\frac{3}{50}$ − $\frac{25}{36}$ ;

= $\frac{303}{50}$   − $\frac{25}{36}$ ;

= $\frac{(303*36)-(25*50)}{50*36} = \frac{10,908-1250}{1800}$ ;

= $\frac{9658}{1800}$ ;
_________________________________
→ Divide EACH SIDE of the "fraction" by "2" ; to simplify:
____________________________________________________
→ $\frac{9658/2}{1800/2}$ ;
= $\frac{4829}{900}$ = 5 $\frac{329}{900}$ ; or, write as:

(5 + (329 ÷ 900) = → 5.3655555555555556 .
→ round to: 5.366 .

Answer from: Quest

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

-3 -3

y=-4x+5

Which of the following equations is equivalent to y+3=-4(x-2)?

Answer from: Quest

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
