Answer:
4 inches
Step-by-step explanation:
The surface area, A of a right square pyramid is given by :
A = a² + 2as
Where, s = height of each triangular surface = x
a = base edge of pyramid
Substituting values into the equation :
A = 84 in² ; a = 6 in ; Slant height, s = x
84 = 6² + 2(6 * x)
84 = 36 + 2(6x)
84 = 36 + 12x
84 - 36 = 12x
48 = 12x
48/12 = 12x / 12
4 = x
Hence, Slant height, x = 4 inches
0.6/0.0024 = 250
.6 goes into 0.0024 250 times
Answer:
y = 5x - 5
Step-by-step explanation:
It appears that the graph intersects the y-axis at (0, -5). This point is the y-intercept of the line.
As we move from (0, -5) to the point (2, 5), x increases by 2 and y increases by 10. Thus, the slope of the line through these two points is
m = rise / run = 10 / 2 = 5.
The slope-intercept form of the equation of a straight line, y = mx + b, becomes y = 5x - 5
Answer:
- 15 2/9
Step-by-step explanation:
3⁻² = 1 / 3² = 1/9
(½)⁻⁴ = 1 / (½)⁴ = 1 / (1/16) = 16
³√(8/27) = ³√8 / ³√27 = 2/3
1/9 - 16 + 2/3 = 1/9 - 144/9 + 6/9 = - 137/9 = - 15 2/9
