A large aquarium should contain 10,000 liters of water when it is filled correctly. Fish will get sick if the aquarium gets down to 4,000 liters or less. One day over the weekend, there is an accident, and the tank cracks in 4 places, causing water to empty out of the aquarium at a rate of 20.5 liters per hour. The aquarium workers did not catch the leaks until 2 days later. How much water was left in the tank when the aquarium workers finally caught the leak? Based on the level of water, were fish sick?

Answer:

6. 4

7. 0

Step-by-step explanation:

6. Slope of line that passes through (-1, -4) and (1, 4):

Slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 - (-4))}{1 - (-1)} = \frac{8}{2} = 4 [/tex]

7. Slope of line that passes through (1, 2) and (-3, 2):

Slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 2)}{-3 - 1} = \frac{0}{-4} = 0 [/tex]

Answer:

2.  12 2/9

Step-by-step explanation:

Because of the choices, I assume the three addends are mixed numerals:

3 4/7 + 4 2/9 + 4 3/7 =

= 3 + 4 + 4 + 4/7 + 2/9 + 3/7

= 11 + 7/7 + 2/9

= 11 + 1 + 2/9

= 12 2/9

Answer: 2.  12 2/9

Answer:

22 m

Step-by-step explanation:

The computation of the how much far does the boat travel is as follows:

sin 43 degrees = 15 ÷ d

d = 15 ÷sin 43 degrees

= 15 ÷ 0.6820

= 21.99

= 22 m

Hence, the how much far does the boat travel is 22 m

We simply applied the above formula so that the correct value could come

The same is to be considered

Answer:

y = (-x-z+8)/3

Step-by-step explanation:

Step-by-step explanation:

Answer:

1.88 to 2 decimal places

Step-by-step explanation:

First, I plugged in 1.8 and 1.9:

1.8^3-3*1.8=0.432

1.9^3-3*1.9=1.159

Then, I plugged in 1.85:

1.85^3-3*1.85=0.78

Next, I plugged in 1.87 to get the answer closer to 1:

1.87^3-3*1.87=0.93

Finally, I plugged in 1.88 to get even closer to 1:

1.88^3-3*1.88=1.00

Hope this helps!

Answer:

Step-by-step explanation:

1.8=-0.568 is too small

1.9=0.159 is too big

1.87=-0.70797 is too small

1.88=0.004672 is too big

Next, I plugged in 1.87 to get the answer closer to 1:

1.87^3-3*1.87=0.93

Finally, I plugged in 1.88 to get even closer to 1:

1.88^3-3*1.88=1.00

1.875=-0.033203125 is too small

so it should be 1.88 to 2 decimal places

Answer:

b

Step-by-step explanation:

denominator(5) stays the same

multiply 2 by 4 since that is 1 fourth of an hour.

So now its 8/5

5 goes into 8 1 time with 3 leftover

So the 1 is a whole number now

the leftover fraction 3/5

=1  3/5

Answer:

40

Step-by-step explanation:

SF of KP to KN = 4

If LM = 32, then we would have to divide 32 by 4 in order to get the missing length of KL.

32 ÷ 4 = 8

Length of KL = 8

Length of LM = 32

Length of KM = 32 + 8 = 40

Answer:

0.75

Step-by-step explanation:

From the attached question, we

3÷ 4

We are asked to find 3÷ 4

3 ÷ 4 = 3/4

We simplify further in other to get a decimal form

3/4 = 0.75

Answer:

B

Step-by-step explanation:

30x = 30 minutes per day

Answer: D

(I might be wrong btw, srry)

Step-by-step explanation:

A and C aren't possible cause they suggest mintues. In your expression 30 is already the minutes. As for B which is really similar to D, it can't be either because it was only for this one season and not all.

Have a nice day :)

Answer:

y = 3x -3

Step-by-step explanation:

Find the slope first

Givens

y2 = 3

y1 = - 3

x2 = 3

x1 = 1

Equation

m= (y2 - y1)/(x2 - x1)

Solution

m = (3 - - 3) / (3 - 1)

m = (3 + 3) / 2

m = 3

Find the y intercept next

Use either point to find the y intercept

y = 3x + b

x = 3

y = 3

y = 3*3 + b

3 = 6 + b

-3 = b

Answer

y = 3x - 3

Answer:

I believe a to the 8th power

Step-by-step explanation:

when you multiple number with numbers in the power place you multiply the numbers and add the power numbers, so in the case a times a is a and -3 plus 5 is 2 or you could think of it as 5 - 3 = 2

Answer:

$9.35

Step-by-step explanation:

14.86+25.88+5.76=46.5

55.85-46.5=9.35

Answer:

The rounded number would be nine

Step-by-step explanation:

It would be nine because you convert 55.85 to 56 then convert 14.86 to 15 convert 25.88 to 26 and convert 5.76 to 6 then subtract all of that to get nine hope it helps

Step-by-step explanation:

Answer:

1

Step-by-step explanation:

Let's look at the first option in this multiple-choice; 18. 18 is divisible by 18, but is not divisible by 35, so that answer isn't right.

What about 3? 3 is divisible by 18, but it isn't divisible by 35. Let's move on.

7 is divisible by 35, but it isn't divisible by 18.

1 is universally divisible by anything. That doesn't mean it is the greatest common factor, but in this case it is, because none of the other options are a factor of both numbers given. Therefore, 1 is divisible by 18.

Answer:

32% increase at the end of 20 years

Step-by-step explanation:

If the population increases at a rate of 1.6% per year, we should multiply it by the number of years that passed, which in this case, is 20. When we multiply those, we get 32%.

We now move to a more detailed exploration of teaching and learning in three disciplines: history, mathematics, and science. We chose these three areas in order to focus on the similarities and differences of disciplines that use different methods of inquiry and analysis.

Step-by-step explanation:

Answer:

2.5 or 2 1/2 apples.

Step-by-step explanation:

5/2 simplified will be 2.5 or 2 1/2.

If you look into it further, because Richard had 15 apples, you subtract 2 1/2 apples he gave Pam which would leave him with 12.5 or 12 1/2. But really the answer is two and a half apples.
