Perpendicular bisector theorem
Answer:
(-2,7) those are the coordinate. in which he will land
You need to use pythagorean’s theorem. so a^2+b^2=c^2.
in this case it would be 6^2+8^2=c2
36+64=100
the square root of 100 is 10
x=10
The bird is flying at 5m/s, so
1 sec = 5 m
It flies for 3 mins
3 mins = 3 x 6sec
3 mins = 180 sec
The bird flies for 180 seconds
1 sec = 5 m
180sec = 5 x 180 = 900m
The bird flew 900m in 3 mins (Answer C)
Answer:
10 years old
Step-by-step explanation:
Let's say the age of the younger sister is x. Then the age of the older sister must be x + 2 because the ages are consecutive <em>even</em> numbers.
"Twice the age of the youngest exceeds the oldest by 8" means that we multiply x by 2 and set that equal to (x + 2) + 8:
2x = (x + 2) + 8
2x = x + 10
x = 10
So, the youngest sister is 10 years old.
