The choices are not given, however, the question can still be solved.

<u>We know that:</u>
pH + pOH = 14
<u>Converting the above equation to concentration form, we will get:</u>
[H₃O+] * [OH-] = 10⁻¹⁴

<u>We are given that:</u>
concentration of hydroxide ion [OH-] = 1.4 * 10⁻¹⁰ M

<u>Substitute with this in the above equation to get concentration of hydronium ion as follows:</u>
[H₃O+] * [OH-] = 10⁻¹⁴
[H₃O+] * [1.4 * 10⁻¹⁰ ] = 10⁻¹⁴
[H₃O+] = \frac{10^{-14} }{1.4* 10^{-10} }
[H₃O+] = 7.1428 * 10⁻⁵ M

Hope this helps :)

It is given in the question that

Ms. Velez will use both x gray bricks and y red bricks to build a wall around her garden. Gray bricks cost $0.45 each and red bricks cost $0.58 each. She can spend up to $200 on her project, and wants the number of red bricks to be less than half the number of gray bricks.

Maximum she can spend is $200. That is

0.45x + 0.58y \leq 200&#10;\\  y< \frac{1}{2} x

And

x\geq 0 , y \geq 0

And that's the required inequalities .

Answer:

Rise over Run

Step-by-step explanation:

The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.
