So first, you need to find the volume of the tank. 25*30*39=29250 cubic cm. If each fish requires 10,000 cubic centimeters of water, you will need to divide 29,250 by 10,000. That would equal 2.925. So, even though it rounds up to 3, the 3rd fish would not have enough space. That leaves us to say that the tank can only hold 2 fish.
Answer:
x < -1
Step-by-step explanation:
Solve -.4x-1.2 >.8 for x.
Start by adding 1.2 to both sides, to isolate -0.4 x:
-0.4x > 0.4
Divide both sides by -0.4, remembering the reverse the direction of the inequality sign:
x < -1
D. no definite shape or definite volume
Answer:
-8/5
Step-by-step explanation:
y values minus each other over x values minus each other
Answer:
The number of miles/the number of hours
Step-by-step explanation:
If the number of hours is not equal to 1, multiply the numerator and denominator by the inverse of the number of hours.
For example, 10 (miles)/2 (hours)
The inverse of 2 is 1/2, so --> the new equation is 10/2 * 1/2 / 1/2 or
10* 1/2 and 2 * 1/2
When multiplied out, this leads to 5/1 or 5 miles per hour
