Answer:
0.4
Step-by-step explanation:
Find square root of 12 and 15
12=3.46 rounded to 3.5
15=3.87 rounded to 3.9
0.9-0.5=0.4
Answer: 24 minutes of commercials
Step-by-step explanation:
96 minutes total divided by 24 which is 4 then 4 times 6 is 24 so 24 min of commercials are in 1 hour and 36 min
Answer:
12.5 mph
Step-by-step explanation:
50 miles / 4 hours=
25 miles / 2 hours=
12.5 mph
ΔABC is a 45 - 45 - 90 triangle. The pattern of its sides is as follows:
Each leg = 1 unit (and both legs are that way, since the triangle is isosceles - so two sides are the same)
Hypotenuse = √2 units.
So if we know either leg, we multiply by √2 to get the hypotenuse. In reverse, we divide by √2 if we know the hypotenuse to get the measurement of a leg.
Our problem tells us that the hypotenuse AC is 10 units. We divide 10 by √2 to get the measurement of leg AB. Since it's a 45 -45 - 90 triangle, AB = BC.

to rationalize the radical

Thus, each leg is 5\sqrt{2} [/tex].
R=x(A+B)
divide both sides by x
R/x=A+B
minus B both sides
(R/x)-B=A
A=(R/x)-B
