Answer:
6 minutes
Step-by-step explanation:
60 * 10% =
60 * 0.1 =
6
Remark
I'm not sure I know what you mean, but I will answer trying to interpret it so it fits the description of the question.
Step One: Set up the equation. The normal way of solving this would be to use the Cos function.
Cos(theta) = Adjacent / hypotenuse = x/8 Multiply both sides by 8
8*cos(theta) = x Theta = 35
8*cos(35) = x This is about as simple a way as is possible.
6.553 = the height of the sale.
Step Three: try using the reciprocal
1 / cos(35)= hypotenuse / adjacent
1/0.8191 = 8/x cross multiply
x = 0.8191 * 8
x = 6.553
The volume of a pyramid is:

You need the height for this. You are given the hypotenuse of a triangle, and the base of that triangle is half of 42 if you can see that. So, let's solve for the height using pythagorean theorem:

Solve for h:

Now you have all the information, let's just plug everything in:

So, your volume is 597.33 cm³. Hope everything makes sense. hmy if something doesn't.
250 - 70 = 180
10 x 18 = 180
