We can dig out the soil from the well equal to volume of well.
Height(h) of well is = 15 meters.
Diameter = 1.6 meters.
So radius(r) =

meter.
As well in cylindrical shapes.
So volume of well =

=

In general

So volume of well is =

cubic meter.
So we can dig out 30.144 cubic meter soil from well.
$2.25 an ounce for unit price
Answer:
$32 is the sales price.
Step-by-step explanation:
First, change the percentage to a decimal.
60% = 60/100 = 0.6
Next, multiply 0.6 with the regular price ($80)
80 x 0.6 = 48
$48 is the discount. Subtract from the original price
80 - 48 = 32
$32 is the sales price.
~
By subtracting 25 from both sides, you get:
AB+CD-25=0
by subtracting CD from both sides, you get;
AB=25-CD
by subtracting AB from both sides, you get:
CD=-AB+25
The way she put it implies that she will sell many water bottles and only one iced tea. the correct equation would be 1.25x+1.49y=100, as she may sell different amounts of each.
