Answer:
Density is usually expressed as grams per cubic centimeter.
Volume = 55 * 25 * 20 = 27,500 cc
Density = Mass / Volume = 4,000 grams / 27,500 cc
= 0.1454545455 grams/cc
which is an extremely low density
Step-by-step explanation:
5+3x/4
5x+1/2(1/4+10). Distributive property
5x+x/8+5. Combine like terms
5+3x/4
50 secs
as $90÷5hrs= 18 $ per hrs
$18÷60min=$0.30 per min
$0.30÷60sec=$0.005 per sec
$0.25÷$0.005= 50sec to make $0.25
so 50sec is the answer
