Answer:
A
B
C
Step-by-step explanation:
A
11=4(7)-17
11=28-17
11=11
B
-13=4(1)-17
-13=4-17
-13=-13
C
-1=4(4)-17
-1=16-17
-1=-1
Step-by-step explanation:
can't really use the Pythagorean because you don't know this is a right triangle.
use the fact that they are similar
so
3/6 = x/12 where x is FE
cross multiply
6x = 36 therefore FE = 6
then 6/12 = y/9 where y is FD
cross multiply
12y = 54 = 54/12 therefore FD = 4.5
1, 0 , 8, and 2 would all lie on the y-axis
Well, there are 60 minutes in 1 hour, and there are 60 seconds in 1 minute, so in 60 minutes, there are 60 * 60 seconds, or 3600 seconds in 60 minutes, or 1 hour, therefore, in 1 hour there are 3600 seconds.
the machine makes 7 aliens in 2 seconds, how many will it make in 3600 seconds?

that many.
