Need help ASAP Select all numbers that are irrational

Answer:

The only irrational number there is π.

Emma always learned that when you multiply by a power of ten, all you need to do is add a zero. She used that trick to solve the following problems:

345 x 10 = 3,450
4,789 x 100 = 478,900
5.6 x 10 = 5.60

Emma’s sister told her that her “trick” doesn’t work, and that 5.6 x 10 is NOT 5.60.
Which girl is correct? How do you know?


help meee plsss you smart people

Answers

Answer:

Her sis is right

Step-by-step explanation:

She is correct because if you multiply a decimal by a power of 10 instead of adding a zero you bring numbers out of the decimal state.

Answer:

Emma's sister is correct

Step-by-step explanation:

When you multiply by a power of ten you are actually just moving the decimal (which in a whole number you don't see) to the right so when it's a whole number yes you just add a zero but in this instance the answer would be 56.

I need help on a math assignment.

Answers

Answer:

(18 , - 10)

Step-by-step explanation:

5x + 4y = 50 .... (1)

x + 2y = - 2 ... (2)

Solve (2) for "x"

x = - 2y - 2 .... (3)

(3) ----> (1)

5(- 2y - 2) + 4y = 50 ⇔ - 6y - 10 = 50 ⇒ y = - 10 .... (4)

(4) ----> (2)

x + 2(- 10) = - 2 ⇒ x = 18

(18, - 10)

the answer is (18, -7). Hope this helps :)

Find the volume of a cone with the radius of 6 height of 8 and length of 10

Answers

The volume of the cone with a radius of 6 units, height of 8 units, and length of 10 units is approximately 301.5928 cubic units.

To find the volume of a cone, you can use the formula:

Volume = (1/3) * π * r^2 * h

Where π (pi) is approximately 3.14159, r is the radius of the cone, and h is the height of the cone.

In this case, the radius is given as 6 units, and the height is given as 8 units.

To calculate the volume, substitute these values into the formula:

Volume = (1/3) * 3.14159 * (6 units)^2 * 8 units

Volume = (1/3) * 3.14159 * 36 square units * 8 units

Volume ≈ 301.5928 cubic units

Therefore, the volume of the cone with a radius of 6 units, height of 8 units, and length of 10 units is approximately 301.5928 cubic units.

A soccer coach filled a water cooler with 34.07 liters of water before a game. The players drank 29.6 liters during their game. How many liters of water were left in the cooler?

Answers

Answer:

4.47 liters

Step-by-step explanation:

To find how many liters were left, subtract the amount they drank from the original amount:

34.07 - 29.6

= 4.47

So, there were 4.47 liters of water left in the cooler.

After players drank 29.6 liters of water from 34.07 liters there is 4.47 liters of water left in the cooler.

What are some alternative names for arithmetic operations?

Addition is also known as the sum, subtraction is also known as the difference, multiplication is also known as the product, and division is also known as the factor.

Given, A soccer coach filled a water cooler with 34.07 liters of water before a game.

The players drank 29.6 liters during their game.

∴ Liters of water that is left in the cooler is the difference between water-filled before the game to the water drank by players during their game which is,

= (34.07 - 29.6).

= 4.47 liters are left in the cooler.

32 bags we sold last Saturday, and 64 today.
