Answer:
66 minutes, or 1 hour and 6 minutes.
Step-by-step explanation:
let us first do the rectangular aquarium:
8 x 10 = 80
80 x 14 = 1120
now the second box
23 x 25 = 575
575 x 33 = 18975
we can divide the boxes volume:
18975/575 = 33
so all we have to do is times 33 by 2 which equals:
66 minutes, or 1 hour and 6 minutes.

You calculate the markup or markdown in absolute terms (you find by how much the quantity changed), and then you calculate the percent change relative to the original value. So they're really just another form of "increase - decrease" exercises.
Example:
A computer software retailer used a markup rate of 40%. Find the selling price of a computer game that cost the retailer $25.
The markup is 40% of the $25 cost, so the markup is:
(0.40)(25) = 10
Then the selling price, being the cost plus markup, is:
25 + 10 = 35
The item sold for $35.

Answer:
Lanza is correct.
Step-by-step explanation:
The two missing dimensions on the left are 4.5 m on the vertical line, and 5 m on the horizontal line.
These dimensions let us partition the garden a number of ways. One way is ...
- a rectangle 9 m by 4.5 m
- a rectangle 4 m by 3.5 m
The total of the areas of these is ...
(9)(4.5) +4(3.5) = 40.5 +14 = 54.5 . . . . square meters
At £16 per square meter, Lanza's charge will be ...
£16 × 54.5 = £872
Lanza is correct that she will have to charge more than £800.
