<h3>
Answer: A and B (first answer choice)</h3>
Explanation:
Both figures shown in A and B are triangular pyramids. The base is a triangle, and the lateral sides are also triangles. Another example would be rectangular pyramids where the base is a rectangle, and the lateral sides are triangles.
Choice C is ruled out because cones aren't considered pyramids.
Choice D is a combination of a rectangular prism, and a rectangular pyramid stacked on top, so it's not purely a pyramid only. We can rule out choice D.
<h3>The value after 4 years is $ 2244.16</h3>
<em><u>Solution:</u></em>
<em><u>The decreasing function is given as:</u></em>
Where,
y is final value
a is initial value
r is decreasing rate in decimal
t is number of years
From given,
a = 3000
t = 4 years
<em><u>Substituting the values we get,</u></em>
Thus the value after 4 years is $ 2244.16
Answer:
2 1/2 or 2.5
Step-by-step explanation:
As you can see in the image, there are 4 whole rectangle's, each divided into two halves. That give's us 8 total parts to work with. Knowing that we need to find 5/8 of 4, simply fill in 5 of those parts. As two parts equal one whole, and one part equals one half, we can determine that 5/8 of 4 converts to 2 1/2, or 2.5.
Equation: of=multiplication
5/8*4=2 1/2
5*4=20.....20/8
20/8 as a mixed number is 2 4/8, which simplifies to 2 1/2.
