Volume of the pyramid:
V = 1/3 · B · h
B = 8 ft²
tan 30° = height / 7√3
1/√3 = height / 7√3
height = 7 ft
V = 1/3 · 8 · 7 = 18.67 ft³ ≈ 19 ft³
Answer : D ) 19 ft³
Answer:
36
Step-by-step explanation:
Quadrilateral's angels always add up to 360. Thus, 2x+5x+6x+7x=360
20x=360 (divide both sides by 20)
x = 18
To find the smallest angle, plugin x into 2x.
2(18)=36
The slope of the line that passes through (5, 4) and (-4,3) is 
<u>Solution:</u>
Given, two points are (5, 4) and (-4, 3)
We have to find the slope of a line that passes through the above given two points.
Slope of a line that pass through
is given as:



Hence, the slope the line that passes through the given points is 
Answer:
72 dollars
Step-by-step explanation:
I = Prt
I(Interest)
P(Principle)
r(rate)
t(time)
I = 800 * 9% * 1
800 * .09 * 1 = 72
The perimeter is the sum of all sides. Since three of the four sides are already given, these values are subtracted from the perimeter to look for the measure of the fourth side. This is shown below:
p = s1 + s2 + s3 + s4
73 = 14 + 19 + 25 + s4
s4 = 73 - 14 - 19 - 25
s4 = 15 ft
Among the choices, the correct answer is A.
