Its not any of them. The answer is 48. She did it completely wrong
-4/9(-9/4)=x/100(-9/4)

the next step would be:
-1=-9x/432
Then the answer would be 48 since you would multiply by 432 and divide by -9

Task 5: A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a const

USPshnik [31]

Answer:

Step-by-step explanation:

To find answer,

We multiply 2 hours by the decrease, which is 3 degrees.

2*3=6 degrees

Now this means it will decrease 6 degrees in 2 hours, and starting from the start we do

0-6= -6 degrees in 2 hours

For five hours, we do

5*3=15

Now do the same

0-15= -15 degrees

Use the list of five irrational below to answer the questions

ExtremeBDS [4]

Answer:

$\text{A.}\ \sqrt{2}\times\sqrt{18}\\\\\text{B.}\ \sqrt{2}\times\sqrt{6}$

Step-by-step explanation:

A: The root will be rational if the product of the numbers under the radicals is a perfect square. For this part, there are a couple of choices.

$\text{1.}\ \sqrt{2}\times\sqrt{18}=\sqrt{36}=6\\\\\text{2.}\ \sqrt{6}\times\sqrt{24}=\sqrt{144}=12$

B: The root will be irrational if the product of the numbers under the radicals is not a perfect square. For this part, there are many choices.

$\text{1.}\ \sqrt{2}\times\sqrt{6}=\sqrt{12}\\\\\text{2.}\ \sqrt{2}\times\sqrt{12}=\sqrt{24}\\\\\text{3.}\ \sqrt{2}\times\sqrt{24}=\sqrt{48}\\\\\text{4.}\ \sqrt{6}\times\sqrt{12}=\sqrt{72}\\\\\text{5.}\ \sqrt{6}\times\sqrt{18}=\sqrt{108}\\\\\text{6.}\ \sqrt{12}\times\sqrt{18}=\sqrt{216}\\\\\text{7.}\ \sqrt{12}\times\sqrt{24}=\sqrt{288}\\\\\text{8.}\ \sqrt{18}\times\sqrt{24}=\sqrt{432}$
