Experimental probability it lands on the green is 8/20 = 2/5
Exp. probability it does not land on green is 1 - 2/5 = 3/5 or 60%.
The difference of the length between the 2 buildings
D=L1-L2
D=95-55
D=40 feet
we use Pythagoras formula
D^2+X^2=Z^2
X=distance between buildings
Z=length of the zip line
Z=50 feet
Answer:
44
Step-by-step explanation:
f(x) = -7x + 5x^2 + 10
f(-2) = -7(-2) + 5(-2)^2 + 10
= 14 + 20 + 10
= 44
Answer:
63mm
Step-by-step explanation:
7mm+8mm=15.
15×15=225
12×12=144(area equals base times height) add 225-144=81(here we are using the Pythagoras theory) so you search for the square root of 81 which is 9 meaning the height is 9. since we say area is 1/2base times height we should take 1/2 ×9×12=63.if the answer doesn't match with the answer in your book please tell me right away so that I can try another method thank you
