Answer:
a = 51
b = 51 (??not so sure)
c = 20 cents
Step-by-step explanation:
a) 25 x 408 = 10200
10200 ÷ 200 = 51 square ft is one one roll.
b) the surface area of an average gift is 51 sq ft (?)
c) 40 ÷ 200 = 0.2
each roll costs $40 dollars. each roll can wrap 200 gifts so 40 ÷ 200 = $0.20/ 20 cents
Answer:
77 feet below sea level.
Step-by-step explanation:
Since y is the time the submarine is ascending, we can plug it in for y and find our answer. We can create an equation where D is the depth and y is time ascending: D = -230 + 17y
Substitute 9 for y:
D = -230 + 17(9)
D = -230 + 153
D = -77
The depth of the submarine after 9 minutes will be 77 feet below sea level. Hope this helps, and Brainly will be highly appreciated.
