Answer:

C (Lake Depth Answer)

Step-by-step explanation:

Here we want to find the math that <u>ends up with 0</u>.

The stock starts with 12$, but loses 16$.

That's -4$ total, not 0.

The ion starts with 19 protons, and 18 electrons. Protons are postive charges, electrons are negative.

This leaves us with 1 proton, not 0.

The lake depth increases by 6 inches, but evaporates 6.

This leaves us back where we started, with 0.

Ahmed spends 25$, but earns 30$.

This leaves us with $5, not 0.

Given the two expressions shown below:

kobusy [5.1K]

<h2>Answer: A. Both are rational.</h2>

Step-by-step explanation:

Although both expressions have square roots, the result of each square root is an integer, which can be expressed as a fraction.

In this sense:

Rational numbers are all numbers that can be represented as the quotient (division) of two integer numbers. This means they can be represented as a fraction in which the denominator is nonzero.

If we solve both expressions, we will be able to see that the result is an integer that can be expressed as a fraction with two integers:

$\sqrt{4} + \sqrt{25}=2 + 5= 7$ The result is an integer

$7=\frac{7}{1}$

$\sqrt{4} + \sqrt{9}= 2 + 3=5$ The result is an integer

$5=\frac{5}{1}$

Between which to whole numbers does the square root of 119 lie?

Stella [2.4K]

Answer:

10 and 11

Step-by-step explanation:

$1^2, 2^2, 3^2, 4^2, 5^2, 6^2, 7^2, 8^2, 9^2, 10^2, 11^2\\1, 4, 9, 16, 25, 36,49,64,81,100,121$

The $\sqrt{119}$ lies between whole number 10 and 11 since it lies between 100-121 which square rooted, is 10 and 11.
