A pet store has three fish tanks, each holding a different volume of water and a different number of fish. Tank AAA holds 40\text{ L}40 L40, start text, space, L, end text and 555 fish. Tank BBB holds 100\text{ L}100 L100, start text, space, L, end text and 121212 fish. Tank CCC holds 180\text{ L}180 L180, start text, space, L, end text and 232323 fish.
Answer:
The tanks by volume per fish from least to greatest:
Tank C, Tank A, Tank B
Step-by-step explanation:
A pet store has three fish tanks, each holding a different volume of water and a different number of fish.
Order the tanks by volume per fish from least to greatest.
Tank A holds 40 L and 5 fish.
= 40L/5 fishes
= 8 volume per fish
Tank B holds 100 L and 12 fish
= 100L/12 fishes
= 8.3333333333 volume per fish
Tank C holds 180 L and 23 fish.
= 180L /23 fish
= 7.8260869565 volume per fish
The tanks by volume per fish from least to greatest
Tank C, Tank A, Tank B

S=80.5km/h
D644
T8 hours
The average speed of the car during the trip given the gasoline used per kilometer is 80.50 km/h.
What is the average speed?
Average speed is the total distance travelled per time. It is used to determine the total distance per time.
Average speed = total distance / total time
644 / 8 = 80.50 km/h.

15 - 5k ≥ 0
solve the inequality
The solution is, the value of the inequality is, 3 ≥ k.
What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
given that,
15 - 5k ≥ 0
now, we get,
Start by adding 15 to both sides
15 + 15 will cancel out
15 + 0 = 15
After you are left with just 5k and 15
Divided 5 on both sides of the inequality
5k/5 ( this will cancel out)
15/5 = 3
Bring down the k & inequality sign
3 - k ≥ 0
adding k on both side,
3 ≥ k
Final Answer : 3 ≥ k

Answer:
A
Step-by-step explanation:
Answer:
-7.5
Step-by-step explanation:
Whole numbers are natural numbers from 0 to infinity. This does not include decimals or fractions. For example, these numbers are 0, 1, 2, 3, 4...
Integers are whole numbers, but they include negative numbers. So, from negative infinity to positive infinity. This does not include decimals or fractions. For example, these numbers are ... -3, -2, -1, 0, 1, 2, 3 ...
A rational number is any number that can be expressed as a fraction. So, this includes -7.5, as -7.5 can be expressed as -[tex]\frac{15}{2}[/tex].
Therefore the answer is -7.5.

(b) Factorise fully.
10x²+6x
Answer:
2x(5x + 3)
Step-by-step explanation:
Factor out common factors. Note that both terms have x inside it. Therefore, you will factor out one x from each term.
Note the factors of both 10 & 6:
10: 1 , 2 , 5, 10
6: 1 , 2 , 3, 6
Note that the greatest factor shared is 2. Divide 2 and x out from both terms:
(10x² + 6x)/2x = 5x + 3
2x(5x + 3) is your answer.

The tables show the statistics of a running back in a football game did he gain more than 50 yards total? Explain .
Answer:
He gained more than 50 yards in the game.
Step-by-step explanation:
Running back in the first quarter in a football game = -8.5 yards
Running back in second quarter = 23 yards
Running back in 3rd quarter = 42.5 yards
Running back in 4th quarter = -2.25 yards
Total gain in the game = -8.5 + 23 + 42.5 - 2.25 = 54.75 yards
That means he gained more than 50 yards in the game.

Lucy and Cody were playing a board game. They rolled a die 142 times. An even number was rolled 56 times. A one was rolled 21 times. A three was rolled 34 times. How many times was a five rolled? Select the correct equation to solve. A. 142 - 56 - 21 + 34 = t B. 142 - 56 - 21 - 34 = t C. 142 + (56 - 21) + 34 = t Solution:
Answer:
[tex]Five = 31[/tex]
Step-by-step explanation:
Given
[tex]Total = 142[/tex]
[tex]Even = 56[/tex]
[tex]One = 21[/tex]
[tex]Three = 34[/tex]
Required:
Number of times 5 were rolled
Even represents 2, 4 and 6.
So, we have:
[tex]Total = Even + One + Three + Five[/tex]
[tex]142 = 56 + 21 + 34 + Five[/tex]
[tex]142 = 111 + Five[/tex]
Collect Like Terms
[tex]Five = 142 - 111[/tex]
[tex]Five = 31[/tex]
