Answer:
1/3 chance for even 1/3 chance for odd
The hydroxonium ion concentration of the fruit juice whose pH as given in the task content is; 5.6 can be evaluated as; [H3O+] = 2.51 × 10^-6.
<h3>What is the hydroxonium ion concentration of the fruit juice whose pH is 5.6?</h3>
Since the given pH of the fruit juice is 5.6, the hydroxonium ion concentration of the fruit juice can be evaluated by means of the formula as follows;
pH=-log[H3O+].
5.6 = -log[H3O+].
-5.6 = log[H3O+].
[H3O+] = antilogarithm (-5.6)
[H3O+] = 2.51 × 10^-6.

Answer:
(1)C- Trapezoid
(2)D-20 square feet
Step-by-step explanation:
<u>Question 1</u>
A cross-section of a rectangular pyramid cut perpendicular to the base but not passing through the top will have two parallel sides where one of the sides will be longer. Therefore, the shape which describes the cross-section will be a trapezoid.
<u>Question 2</u>
The base of the Triangle = 5 feet
Height of the Triangle = 8 feet
![\text{Area of a triangle}=\dfrac12 \times $Base \times Height\\=\dfrac12 \times 5 \times 8\\=20 ft^2](https://tex.z-dn.net/?f=%5Ctext%7BArea%20of%20a%20triangle%7D%3D%5Cdfrac12%20%5Ctimes%20%24Base%20%20%5Ctimes%20Height%5C%5C%3D%5Cdfrac12%20%5Ctimes%205%20%20%5Ctimes%208%5C%5C%3D20%20ft%5E2)
