Please help!!!!!! find the area of the whole rectangle.
Olegator [25]

Answer:

Step-by-step explanation:

The area of a rec tangle is A x W

but first you have to find the area of the triangle wich is going to be 127.5.

Then you have to multiply 127.5 times 15.

And that will give you 1,912.5.

I think this is correct, but im not sure.

The equation for the pH of a substance is pH = –log[H+], where H+ is the concentration of hydrogen ions. Which equation models t
Zanzabum

Answer:  [H+] = 10^-7.2

Step-by-step explanation:

Given that the PH of the solution = 7.2

Using the formula pH = –log[H+]. To get the H+ concentration from the pH, raise both sides by the base of 10. Then we have

10^ -pH = H+. with pH of 7.2,

Thus the answer to this problem is

[H+] = 10^-7.2

Is QRS a right triangle? Why or why not?
Yuliya22 [10]

Answer:

C

Step-by-step explanation:

Using Pythagoras' identity to determine if the triangle is right

The square of the longest side should equal the sum of the squares on the other 2 sides, that is

QS² = RS² + QR² = 8² + 5² = 64 + 25 = 89 ( take the square root of both sides )

QS = \sqrt{89}

Δ QRS is not right as QS would have to be \sqrt{89}
