Explanation:

This looks like an essay question with no right answer.

There are two "special" right triangles:

isosceles 45°-45°-90° triangle with sides in the ratios 1 : 1 : √2

30°-60°-90° triangle with sides in the ratios 1 : √3 : 2

These side lengths give rise to the trigonometric ratios shown below for angles with 30°, 45°, or 60° as reference angles.

Since Carmen gives two coins to Frankie for every five that she gets, she effectively only gains 3 coins at a time. Therefore, if she has 9 coins, Frankie must have 6.

What is the height of a rectangular prism that has a volume 192 cubic feet and a base with an area of 48 square feet?

Westkost [7]

Answer:

A rectangular prism has 3 measurements: length (l), width (w), and height (h)

The volume of a rectangular prism has the formula: V=lwh

The area of the base of the rectangular prism is its length times its width; or

Area of base = lw

So, the volume of the rectangular prism can be written as:

Volume = area of the base * height

Substitute in your numbers:

192=48*h

h=192/48

h=4

So the height is 4 feet

Step-by-step explanation: Hope this helps. :))

Answer:

Sam

Step-by-step explanation:

Sam made a mistake when he said $10^2 -20$ . The steps should have been:

$2n^2-20=2(5)^2-20\\2(25)-20\\50-20=30$

You are supposed to square 5 first before multiplying 2. Sam multiplied by 2 first. The correct answer is 30.
