Answer:
<h2>1 9/20</h2>
Step-by-step explanation:
Convert the fraction to decimals by dividing
7/10 = 0.7 add 2 = 2.7
1/4 = 0.25 add 1 = 1.25
2.7 - 1.25 = 1.45 = 1 9/20
I'm always happy to help :)
<h3>
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:
820
Step-by-step explanation:
779/x = 95/100
779×100
77,900 ÷ 95
820
I think it is D
Hope my answer help you?
The equation will be:
y = -2
Step-by-step explanation:
A horizontal line has no slope as it is parallel to x-axis.
The horizontal line is in the form y = b where b is the y-intercept.
Given
The line passes through (4 -2).
The y-coordinate of the given point is -2 which means that the line will intersect the y-axis on -2
So,
b = -2
and
The equation will be:
y = -2
