It also means that a rhombus is formed from 2 identical equilateral triangles ( 2 identical 30 - 60 - 90 triangles forms one equilateral ) and a side of that triangle measures : 30 feet.
Answer:

Answer:
m = 1
, y = 1
x + 10
Step-by-step explanation:
The equation of a line is y = mx + c where m is the slope and c is the y-intercept. I will be calculating the slope using the points (7, 2) and (0, 10)
m =
= ![\frac{2-10}{7-0}](https://tex.z-dn.net/?f=%5Cfrac%7B2-10%7D%7B7-0%7D)
=
= 1![\frac{1}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B7%7D)
Based on the graph, the y-intercept is 10. Thus, the equation of the line is 1
x + 10.
to solve you would have to divide 1 into 8. So using long division the answer would be 0.125
Answer:
d. 175 square inches
Step-by-step explanation:
If we assume the base is square and all triangular faces are congruent, then the lateral area of the figure is that of four triangles. Each triangle has an area that is half the product of its base and height:
A = (1/2)bh = (1/2)(7 in)(9 in) = 31.5 in^2
The area of the square base is the product of its length and width, both of which are 7 in.
A = lw = (7 in)(7 in) = 49 in^2
So, the total surface area is that of the base plus the four sides:
surface area = (49 in^2) + 4(31.5 in^2) = 175 in^2 . . . . . matches choice D
