Actually, the "slant height" is 4, but the vertical height or "altitude" of the equilateral triangle is not 4
but anyway.....
and the volume, is the area of the triangle, times the length, so, whatever you get for the area of the triangle * 10
Answer:
The equation has two solutions for x:
<u>x₁ = (8 + 10i)/2</u>
<u>x₂ = (8 - 10i)/2</u>
Step-by-step explanation:
Let's use the quadratic formula for solving for x in the equation:
X^2 - 8X + 41= 0
x² - 8x + 41 = 0
Let's recall that the quadratic formula is:
x = -b +/- (√b² - 4ac)/2a
Replacing with the real values, we have:
x = 8 +/- (√-8² - 4 * 1 * 41)/2 * 1
x = 8 +/- (√64 - 164)/2
x = 8 +/- (√-100)/2
x = 8 +/- (√-1 *100)/2
Let's recall that √-1 = i
x = 8 +/- 10i/2
<u>x₁ = (8 + 10i)/2</u>
<u>x₂ = (8 - 10i)/2</u>
Answer:
Step-by-step explanation:
A =adults
C = children
$8*A + $5*C = $76
So there are 4 children
$8*A + $5*4 = $76
$8*A + $20 = $76
$8*A = $76 - $20
$8*A = $56
A = 56/8 = 7
There are 7 adults attending the play.

Answer:
x=-12.5
Step-by-step explanation:
divide both sides
-0.2/(-0.20)=2.5/(-0.2)
x=2.5/(-0.2)
x+-12.5
