Answer with explanation:
Pyramid and Plane both are three dimensional shapes.
Pyramid is a three dimensional shape having base any polygon and other faces as triangles.
The base of pyramid is horizontal.
1. If lower base is a Square,or rectangle or any other parallelogram
And, then , plane cuts the pyramid vertically
It will be also, a three dimensional shape ,resembling a triangular cross section in three dimension.
Triangle is appropriate choice.
Answer:
d=sqrt29
Step-by-step explanation:
This problem requires the distance formula, d = sqrt([x1 - x2]^2 + [y1-y2])
x1 and y1 are the x and y coordinates of the first point, and x2 and y2 the second.
Plug in the values.
d = sqrt([4 - 2]^2 + [7-2]^2)
Simplify
d=sqrt(2^2 + 5^2)
d = sqrt(4 + 25)
d=sqrt29
If you'd like a visual representation of the distance formula, google it and it will show you.

Answer:
a. $20.45
b. $24.55
c. $4.55
Step-by-step explanation:
In this question, we are asked to calculate the cost price and profit or loss selling a pair of shoes.
we proceed as follows
Firstly, we want to find the cost price given the selling price and the mark up percentage.
mathematically;
profit =( selling price - cost price)/cost price * 100%
here our profit is 120% with the cost price being $45. we plug these values
120 = 45-cp/cp * 100%
120cp = 100(45-cp)
120cp = 4500 -100cp
220cp = 4500
cp = 4500/220 = $20.45
His profit is selling price - cost price = 45 - 20.45 = $24.55
His profit selling same shoe for $25 is 25-20.45 = $4.55
