In a square, one pair of opposite sides was made 50% longer and the other pair of opposite sides was made 50% shorter.

1 answer:

8 0

You have a square with an area of 100 meters^2.
if you decrees a pair of opposite sides by 50%. you end up with a rectangle with the area of 50 meters^2.
then you increase the other pair of opposite sides by 50%. you end up with a rectangle with the area of 75 meters^2. OK now I see what I did wrong.

The correct answer is 75%

Determine the temperature of 2.6 moles of gas contained in a 5.00-L vessel at a pressure of 1.2atm.

strojnjashka [21]

Answer:

28.108 K.

Step-by-step explanation:

Given: Pressure (P)= 1.2atm

Number of moles (n)= 2.6 moles

Volume (V)= 5.00-L

Now finding the temperature (T).

Formula; T= $\frac{P\times V}{n\times R}$

R is a constant factor which makes other factors work together.

There is a numerical value for R which we use is $0.0821 \times \frac{L.atm}{mole.K}$

∴ Temperature (T)= $\frac{1.2\times 5}{2.6\times 0.0821 \frac{L.atm}{mol.K} }$

⇒ Temperature (T)= $\frac{6}{0.21346} = 28.1083\ K$

∴ Temperature is 28.108 K

Answer:

Option C: $\sqrt{\textbf{121}}$

Step-by-step explanation:

Given the side length of a square is 11 units.

Note that $\sqrt{121} = \pm 11$

Since, length cannot be negative, we can eliminate - 11.

Hence, the length of the side of the square is 11 units = $\sqrt{11^2} = \sqrt{121}$ .

Hence, the answer.

when Apple sells their iPads they increase the price $50 from what it cost then to actually make the iPads one Apple Store sold

Anvisha [2.4K]

First things you have to do is figure out how much they increased the iPads by:

$50 • 10 = $500

They increased the iPad price by $500.

Subtract the total amount from the iPad price:

$5,000 - $500 = $4,500

The actual price of 10 iPads, without an increase is $4,500

Now divide that by 10 to get the amount for one iPad:

$4,500 ÷ 10 = $450

One iPad actually costs $450 to make.
