A 16-ounce bottle of spring water is $1.76. A 20-ounce bottle of fresh water is $2.40. which statement about the unit prices is
2 answers:
Answer:
A) Spring water has a lower unit price of $0.11/ounce
Step-by-step explanation:
Given,
The cost 16-ounce bottle of spring water = $ 1.76,
So, the cost of 1 ounce bottle of spring water = = $ 0.11
That is, the unit price of the spring water is $0.11 per ounce,
Also, the cost 20-ounce bottle of fresh water = $ 2.40,
So, the cost of 1 ounce bottle of fresh water = = $ 0.12
That is, the unit price of the fresh water is $0.12 per ounce,
Hence, spring water has a lower unit price of $0.11/ounce

A tetrahedron is a triangular pyramid. It has four triangular faces and four vertices.
In the question, we are told that the length of the edges are all equal = 20m and the length from one corner to the center of the base = 11.5m
We sketch a diagram of a tetrahedron with the given measurement as shown below
To find the height, we will use the Pythagoras theorem
20² = h² + 11.5²
h² = 20² - 11.5²
h² = 267.75
h = √267.75
h = 16.36 (rounded to two decimal places)

Check the picture below.
since the vertical distance, namely the y-coordinate, is twice as much as the horizontal, then if the horizontal is "x", the vertical one must be 2x.
let's find the hypotenuse first.
