the temperature at 6;00 am was - 20 and it was 8 degrees warmer than at midnight so if the temperature at 8:00 am was 12 degrees warmer than at midnight what was the temperature at midnight
at midnight it was -20 - 8 = -28
by the way at 8 am it was -28+12 = -16
thanks.:)
You are welcome.
-20 - 8 = -28 at midnight
thanks Anonymous and Ms Sue.!
You're welcome.
Can i ask one more
question
Sure.
a=1/2 (b1+b2)h plug in the number and solve for a
What are b1 and b2?
Which number are you plugging in for which unknown?
base and top of a trapezoid of height h ?
i dont know my teacher gave it to us like that
If you Google area of a trapezoid you will find an online calculator :)
Oh --base 1 and base 2. :-)
What are the measurements for these two bases?
What is the height?
Well, Google that
area of a trapezoid
and you will find your formula and how to do it.
5 in,8 in ,11 in ,4 in
note that (1/2)(b1+b2) is the average width of the trapezoid
so you are really multiplying the height times the average width
LOL, too many, three numbers not 4
b1 =
b2 =
h =
then calculate area A
hmmm, note that 8 = average width
5+11 = 16 and 16/2 = 8
I bet you just have
8*4 = 32
