Answer:
24:5
Step-by-step explanation:
4 yards is 3 feet, so 4*3=12. There are 12 inches in a foot, so 12*12=144. 144:30= 72:15 = 24:5
Answer:
Step-by-step explanation:
Multiply out 
in order to find out which expression it is equivalent to.
1) Since the whole quantity is squared, write it out as 
.
2) Multiply binomials by using the FOIL method. Multiply the terms that are listed first in each binomial, then the ones that are listed outermost when looking at both binomials, then innermost, and finally the last terms listed in each binomial. Simplify and combine like terms.
3) 
, so 
must be 
. Thus, 
is equivalent to -1. Knowing this, simplify and combine like terms.
Thus, it is equivalent to 
.
The third one tells us the price is $12 per liter, that is to say, the top number is twelve times the bottom number.
.25 × 12 = $3
.7 × 12 = $8.40
2.5 × 12 = $30
3.52 × 12 = $42.24
$57.60 / 12 = 4.80 liters
I don’t think f would have any value in this equation and f would represent 1 zero??
