Answer:
1 : 30
Step-by-step explanation:
4 seconds : 2 min
however we know that 1 min has 60 seconds. Hence 2 min will have 2 x 60 = 120 seconds
Therefore we can substitute 2 min with 120 seconds
4 seconds : 2 min
4 seconds : 120 seconds (simplify by dividing both sides by 4)
4/4 : 120/4
1 : 30
I is C because you use the pythag theorem
I'm guessing you are talking about the surface area of a cone?
<span>Also by length of the edge, do you mean slant height?
Here is the area formula for a cone:
Lateral Area = (<span>π<span> • r •<span> slant height)
Solving for "r" we get:
</span></span></span></span>
radius = Lateral Area / (<span>π<span> • </span></span><span><span>slant height)</span><span><span /></span></span>
When you calculate the radius, you can solve for the height by
height^2 = slant height^2 - radius^2
<span>2x-5y=-6
8x+3y=68
|x y +1|
|2 -5 6| = 0
|8 3 -68|
DET = 6+40 = 46
x*DET = 340-18
x = 7
-y*DET = -136-48
y = 4
