Answer: x=19
Step-by-step explanation:
a triangle always=60 so
14+12+15=41
41-60
=19
Answer:
A graphing calculator can do quadratic regression on the given points. It tells you the cost function is
.. c(x) = (1/2)x^2 +8x +10
Then c(12) = 178
The cost function predicts the total cost of producing 12 camera cases is $178.
Step-by-step explanation:
<3 follow
It has to have an average of 10 feet per minute for 5 minutes, which means in five minutes the total of feet would have to be 50.
So you would add all these numbers up and you would get 38.
50 - 38 = 12 so the answer is 12ft
I this helps you out with your problems
Have a nice day
Ok, to solve this, once again you need to fold this map back up into a 3d shape ( in your head).
What you should see is that the little overhanging sides that had no measurement, now have a measurement. They measure up to be the same as the 3m. sides.
so to find the area of all the rectangles, you need to multiply the base times height. (b)h
I will start from the left of your pic. and work my way to the right...not including the little overhanging ones.
The first one should measure out to be 3(15) =45
The second to be 6(15) =90
The third to be 3(15) =45
The fourth to be 6(15) =90 :)
So you have these, but now you need to get the little over hangers I call them...lol.
The width is 6, same as the rectangle they are attached to. And the picture in your mind should tell you that the height is 3, the same as the width of the skinny rectangles that they attach to in your mind.
Soooo now they measure out to be 3(6) =18. and you just multiply this by two because they are the same area, right? So that would be 36.
ok. Now add all of the areas of the surfaces 45+90+45+90+36 to get a total surface area of.... *drummel please* 306m^2
this means 306m. to the power of 2 if you didn't know.
well, I hope you understand better and I hope I helped! ;)
