I suppose the restaurant's coordinates are (0, -9), but it is all relative, unless the coordinates of the restaurant have a y-value 9 less than the coordinates of the theater
Answer:
The height is 20 meters
Step-by-step explanation:
First set up the equation (Area)80=bh/2 then set up another equation, (height) h=4+2b (base). After this you can substitute h in the equation to end up with 80=(b(2b+4))/2 simplify it to get 80=b^2+2b then solve. The base is 8 meters, plug into the formula that we made before and you find the height is 20 meters.
Notice that 36.6 = 37 - 2*0.2 and 37.4 = 37 + 2*0.2, so the range of temperatures 36.6 to 37.4 fall within 2 standard deviations of the mean. The empirical rule says the approximate percentage of humans with body temperatures in this range is 95%.
12×10 to the power of zero is 1.2×10 to the power of one and 12 times one is 12
He walked 1/2 miles......then walked 3/8 miles...
1/2 + 3/8 = 4/8 + 3/8 = 7/8...so he walked 7/8 of a mile <==
