Used the distributive property to solve.,
Hello there ^ _ ^
121x² + 64 = 0
121x² = 0 - 64
121x² = -64
x² = 64/121
Now take square root
x = +/-√-64/121
I hope this help!
Answer:
42 in binary number is 101010.
Trains depart after every 4 minutes.
Total time train takes to complete a circuit= 24 minutes
Evan sets off at 8:30 am, so he will be back at 8:54 am.
So time of trains coming in opposite direction:
8: 34 am
8:38 am
8:42 am
8:46 am
and 8:50 am
5 trains coming in opposite directions.
Now the trains started at 8:06 am from the stations are:
8:06 am
8:10 am
8:14 am
8:18 am
8:22 am
and 8:26 am.
So there are 6 trains started the circuit at 8:06 am.
Now total number of trains=6+5=11 trains
Answer: 11 trains will pass on complete circuit.
When it is 3:00 the minute hand and the hour hand would form a 90 degree angle making a right triangle. If you use the Pythagorean theorem you can find the distance between the tips of the hands.
14^2+9^2=x^2
196+81=x^2
277=x^2
X=16.64ft when rounded
