10

It doesn't say they jumped out of the tank.

Answer:

Im not quite sure but I think it is either 10, cause it says there are 10 fish in the tank. Either that or 8 (ill explain)

Step-by-step explanation:

1 died, but that doesnt mean it was taken out of the tank. 3 swam away, but if they are in a tank they probably just swam to a different part of the tank. 4 choke on water, but that doesnt mean they didnt recover. however, the "2 are breathing" part got me confused since the definition of breathing means taking in air and expelling stuff out...fish "breathe" water so it didnt make sense. So, if you include the 2 breathing fish there are 10, but if u dont there are 8.

I really hope this helps :)

Answer:

75 minutes

1 hour and 40 mins is equal to 100 mins

Divide 100/75 and you get 1.33333, meaning you multiply 75 by 1.33333 to get 100, meaning there is a 33.333333% increase

Answer:

5.4 feet

Step-by-step explanation:

Start with the flagpole. It is 5/9 of 32 2/5.

32 2/5 = 162/5.

5/9 * 162/5 = 162/9.

Ramiro is 3/10 as tall as 162/9.

3/10 * 162/9 = 27/5, or 5.4 feet tall

His height is 5.4 f

Answer:

I believe the answer is (4 * 5 +1) = 21

Step-by-step explanation:

The fewest number of beads you must pick to be absolutely sure there are 5 beads of the same color is 20 + 5 = 25 beads.

To guarantee that you have picked 5 beads of the same color, you need to ensure that you have at least 4 beads from each of the 5 colors.

To calculate the fewest number of beads you must pick, we can consider the worst-case scenario where you have picked the maximum number of beads from each color without having 5 of the same color.

In this scenario, you would have 4 beads from each color, which totals 4 * 5 = 20 beads.

However, to guarantee that you have 5 beads of the same color, you need to pick one more bead from each color, which is an additional 5 beads.

Therefore, the fewest number of beads you must pick to be absolutely sure there are 5 beads of the same color is 20 + 5 = 25 beads.

Step-by-step explanation:

you will see, this is totally easy. so, once you understand that principle, I am sure you will agree with me that this costs more time putting it in here than just doing it yourself in the future.

you need to consider for addition and subtraction every variable combined with an exponent a different thing, a fruit for example.

you know exactly what to do, when you are being asked to add 3 apples to 2 apples, right ?

or, when are are asked to add 4 apples and 2 pears to 3 apples and 2 pears.

in the first case we simply get 5 (2+3) apples.

in the second case we get 7 (3+4) apples and 4 (2+2) pears.

and nothing else happens here.

we could call x² apples, y² pears, y³ plums, x kiwis, t strawberries, t² raspberries. and the constants could be another fruit or grams of sugar.

now, we simply combine the "fruits" that belong together. there is nothing more to this.

5x² + 3y³ - 4x² = x² - 3y³ (because 5-4 for x²)

y³ + 2y³ - 8 + 2 = 3y³ - 6 (1+2 for y³ and -8+2 constant)

9 - 3x - 4x + 2x - 12 = -5x - 3

-6t + 4t² - 6 + 7t - 4t² = t - 6 (4-4 for t², -6+7 for t)

Answer:

1,165

Step-by-step explanation:

To solve 1,175 ÷ 5 by using partial quotient we should subtracted 10², when multiplied by 5.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

The expression is,

⇒ 1,175 ÷ 5

Now,

Solve the expression 1,175 ÷ 5 by using partial quotients as;

5 ) 1,175 (

   - 500       100

     ------

      675        135

     -675

     --------

The simplified expression is [tex]27/(16x^6y^8).[/tex]

We have,

To simplify the expression [tex]4(3x^2y^4)^3 / (2x^3y^5)^4,[/tex] we can simplify each part separately and then divide.

Let's simplify the numerator first:

[tex](3x^2y^4)^3 = 3^3 * (x^2)^3 * (y^4)^3 = 27x^6y^{12}[/tex]

Now, let's simplify the denominator:

[tex](2x^3y^5)^4 = 2^4 * (x^3)^4 * (y^5)^4 = 16x^{12}y^{20}[/tex]

Now we can divide the numerator by the denominator:

[tex](27x^6y^{12}) / (16x^{12}y^{20})[/tex]

To divide the variables with the same base, we subtract their exponents:

[tex]27/16 * x^{6-12} * y^{12-20}[/tex]

Simplifying further:

[tex]27/16 * x^{-6} * y^{-8}[/tex]

To make the exponents positive, we can move the variables with negative exponents to the denominator:

[tex]27/(16x^6y^8)[/tex]

Therefore,

The simplified expression is [tex]27/(16x^6y^8).[/tex]
