Answer:
D
Step-by-step explanation:
A rational number will either end or repeat forever like the first three, but the fourth one, pi, will go on forever and never repeat, making it irrational.
Answer:
Step-by-step explanation:
By the Pythagorean theorem, triangle BCD has
and triangle ABD has
.
Substituting the first equation into the second equation for 
gives the equation
Now triangle ABC has
Expanding out the left side, 
.
Now substitute the equation from before, 
, into the new equation.
We work to isolate 
by adding 
to both sides of equation and subtracting 
from both sides.
Divide both sides by 2 and you get 
Assume that x is positive and square root both sides to get the final result of
Answer:
B
Step-by-step explanation:
Here, we simply want to know who will reach the 6-foot mark sooner
Mathematically, we need to get the slope from the graph
Looking at the graph, we can see that the 3 ft mark was reached at exactly 2 seconds
So what this mean is that, in 4 seconds, the 6 ft mark will be reached
This makes up the fact that the speed for Pete’s travel is 1.5 ft/ secs
Now compare this with what Stephano has, which is 2.25 ft/ s
we can see that stephano is traveling at a better speed and will reach the 6 ft mark first
So the correct option is B
Answer:
140 degree
Step-by-step explanation:
Since the sum total of a polygon is 540 degree, simply subtracts from each degree of the other angles.
540 degree - 110 degree - 85 degree - 125 degree - 80 degree = 140 degree
