Answer:
9 gallons of water per minute
Step-by-step explanation:
First identify what you know:
1) The pipe was flowing water for eight minutes.
2) In that eight minutes, 72 gallons of water came out.
So, if 72 gallons of water came out in eight minutes, how many gallons flowed out in a single minute? Well, assuming that the flow rate was consistent, then simply divide the total number of gallons that flowed out, by the number of minutes the pipe was open!
72/8 = 9
The pipe released 9 gallons of water per minute, thus resulting in 72 gallons of water in 8 minutes!
Hope this helps! :)
Answer:
5
6
Step-by-step explanation:
To solve, collect like terms
x ≥ 2 + 21/2
x ≥ 4 1/2
the whole number that would be greater than 41/2 would be 5
2. 2.7 + 3.3 > x
6 > x
Answer:
we will need 7 bags
Step-by-step explanation:
To solve this problem we first have to calculate the total area of the garden
a = area
b = base = 8m
h = height = 12.5m
a = b * h
we replace with the known values
a = 8m * 12.5m
a = 100m²
Now that we know the total area of the garden and the area occupied by a single bag, we divide the total area by what a bag covers.
100m² / 16m² = 6.25 bags
because we cannot buy a fraction of a bag we will need 7 bags
This question seems to be a good example of why we need to learn math!
P=present value
i=interest rate = 0.02 per year
time, t=1 year
we need P such that
interest = Pit ≥ 9.99
or
P(.0002*1) ≥ 9.99
=>
P ≥ 9.99/0.0002 = 49950
Answer: it takes a minimum balance of $49950 to cover a "below minimum balance fee" of $9.99.
