Answer: Choice B) 468 cm^2</h3>
============================================================
Explanation:
As the diagram shows, we have a triangular face with a base of b = 18 and height of h = 13. The area of this triangular face is:
A = 0.5*b*h
A = 0.5*18*13
A = 117 square cm or cm^2
This represents the area of one face, but there are 4 identical copies of this triangular face assuming this tetrahedron is a regular polyhedron. So we have a total surface area of 4*117 = 468 cm^2 which points us to choice B
This is the amount of paint you'll need to cover the outer surface of the pyramid, or you can think of it as the amount of wrapping paper needed. This assumes there are no gaps or overlaps.
Answer:
x=10.7
Step-by-step explanation:
Our proportion is
x/4=8/3
We can cross multiply to solve.
This is where you multiply one fraction's numerator with the other fraction's denominator and vice versa.
x*3=4*8
3x=32
Divide both sides by 3.
x=10.6666666667
Round.
x=10.7
In order to find the answer to the question u need to get x by its self
Answer:
10:7
Step-by-step explanation:
ratios are simply just like fractions!
this ratio (40:28) can be re-written as 40/28
now, you can simplify this to its lowest terms
40/28=20/14=10/7
first in those steps i re wrote the question, then divided by two, then divided by two again !
so, 40:28=10:7
--------------------------------
you can even check this by cross multiplying, since ratios are fractions
40x7=28x10
280=280
they are equivalent which means our ratio is correct :)
hope this helped <333
