Answer:
75 liters are left in the bathtub
Explanation:
First, we should know that a hectoliter is a unit of capacity that is equal to 100 liters.
We are given that the bathtub holds 1 hectoliter of water.
This means that the bathtub holds 100 liters of water.
We are also given that 25 liters of water were drained from the bathtub.
This means that:
remaining amount of water = original amount - drained amount
remaining amount of water = 100 - 25
remaining amount of water = 75 liters
Hope this helps :)

11 units
Step-by-step explanation:
HPO and DPI are similar triangles
HP/DP = PO/PI
HP/9 = 6/27
HP = 9×6/27
HP = 2
HD = HP + PD
HD = 2 + 9 = 11
Answer:
$36 (see below)
Step-by-step explanation:
First, you have to find how much they paid for one ticket.
If they paid $12 for 3, then they paid $4 for 1.
You could've also use a ratio:
$12 $x
-------- = --------
3 1
Cross multiply:
$12 (1) = $3x
$12 = $3x
$4 = x
So $4 for 1 ticket.
To find the cost of 9 tickets, just multiply the price by the number of tickets, which is:
$4 (9) = $36
Answer:
x = 2
Step-by-step explanation:
3(x - 1) = 23 - 5(x + 2) ← distribute parenthesis on both sides
3x - 3 = 23 - 5x - 10
3x - 3 = 13 - 5x ( add 5x to both sides )
8x - 3 = 13 ( add 3 to both sides )
8x = 16 ( divide both sides by 8 )
x = 2
The percentile rank of a certain score is the score percentages in its frequency distribution that are equal to it or lower that it.
