Answer:
the number of boxes that would take fill
the storage completely is 6<u>0 boxes.</u>
Step-by-step explanation:
given:
A storage unit has the dimensions 6 ft. x 7 1/2 ft. x 4 1/2 ft.
find:
What number of
1 1/2 ft. x 1 1/2 ft. x 1 1/2 ft. cardboard boxes would it take to completely
fill this storage unit?
Volume of a storage unit = 6 x 7.5 x 4.5
Volume of a storage unit = 202.5 ft³
Volume of a cardboard box = 1.5 x 1.5 x 1.5
Volume of a cardboard box = 3.38 ft³
to get the number of cardboard boxes to fill in the storage unit,
Number of boxes = <u> 202.5 ft³ </u>
3.38 ft³
Number of boxes = 60
therefore,
the number of boxes that would take fill the storage completely is 60 boxes.
Answer:
Most of the money which can be invested at 6% is $6000
Step-by-step explanation:
Total amount of money = $8500
Let most of the money which is invested at 6% = x
So, most of the money which is invested at 7% = 8500 - x
Now, amount of interest which is guaranteed per year = $535
So, according to the given condition, We have :
6% of x + 7% of (8500 - x) = 535
⇒ 0.06·x + 0.07·(8500 - x) = 535
⇒ 0.06·x + 0.07 × 8500 - 0.07·x = 535
⇒ -0.01·x = -60
⇒ x = 6000
Hence, Most of the money which can be invested at 6% is $6000
