Hi there!
To solve this problem, we need to multiply each number by 4 ft.
8×4=32
5×4=20
Now, we films the area.
32×20 = 640
The area of the room is 640 feet squared.
Hope this helps!
Answer:
x = 3/2
Step-by-step explanation:
2^2x = 2^3
2x = 3
x = 3/2
#11
Each roll is 9' long,
length of each roll = 9' * (12"/foot) = 108"
Each ribbon piece = 15", so number of ribbons per roll
=108/15=7 with 3" left over, which is assumed not possible to be joined with other pieces.
Therefore, with 5 rolls, there are 7*5=35 pieces of ribbon, with 5 pieces or 3" left over.
So according to the question statements
6% of the $40k and 7$ of the second $40k and 9% ammount of the $80k
the answer would be
40000 * 0.06
+ 40000 * 0.07
+ 25000 * 0.09
= 270250
23.25 just cut the cost of the example in half
