Answer: 2 feets
Step-by-step explanation:
Recommended density = 7 fish/ ft^3
If recommended density guideline is followed:
Number of fishes in aquarium = 42
Length of aquarium = 3ft
Width = 1ft
Height =?
Volume of aquarium = Length × width × height
Volume = 3 × 1 × h = (3ft^2 × h)
Therefore ;
If
1ft^3 = 7 fishes
x ft^3 = 42 fishes
Cross multiply
7(x)ft^3 = 42 fishes
x ft^3 = (42÷7)
x ft^3 = 6
Therefore volume of the aquarium with 42 fishes is 6ft^3
Volume = (3ft^2 × h)
6ft^3 = 3ft^2 × h
h = (6ft^3) / (3ft^2)
h = 2ft
1) 7
3, 4
2, 1, 3
6, -4, 5, -2
1 minute it travels 35/60 miles
so in 180 min it travels 35/60×180 miles = 105miles...
The equation we would use here would be 45 + 0.75x = C
This is because we have a flat fee of $45 and you are being charged $0.75 per mile, so it depends on how many miles were driven.
To find out how much it would cost if it were to drive 110 miles, we simply put 110 in place of x;
45 + 0.75(110) = C
And now we solve!
45 + 82.50 = C
$127.50
Hope this helps!
Answer:
A. The domain is (1,∞), and the range is (-7,∞)
Step-by-step explanation:
Well lets graph it first,
Look at the image below ↓
By looking at the image we move it 3 units right and 3 units down.
Then it will be located at the point (1,-7).
Meaning for the domain it starts at 1 and goes on for infinity.
And For the range it starts down at -7 and goes down for infinity.
<em>Thus,</em>
<em>the correct answer is choice A.</em>
