<span>if isabel runs 7 miles in 50 minutes, then you know she runs 7/50 miles in one minute, right? So multiply that by the number of minutes she did run, and you can find the distance:
</span><span> 7
------ x 75 =
50
525
------
50
</span><span> If you plug that fraction into your calculator, you get 10.5, so 10 and a half miles.</span>
multiply width times the height to get the rectangle area
5 x 7 = 35 units squared
I may be wrong but I think you may be over complicating it its okay I do that a lot too
Cos 52 = 0.6157
sin 42 = cos 48 = 2/3 (because 42 + 38 = 90 - complementary angles)
if tan 20,5 = 3/8 then tan 69.5 wil = 1 / 3/8 = 8/3
The volume of this right rectangular prism is 263.52 and it is to the nearest hundredths as a decimal, hope it helps!
