Answer:
AE = 15 cm; ED = 18 cm; AD = 15 cm (given)
Step-by-step explanation:
ΔBEC ~ ΔAED so ...
AD/BC = AE/BE = (BE+AB)/BE = 1 + AB/BE
Substituting given numbers (lengths in centimeters), we have ...
15/10 = 1 + 5/BE
1/2 = 5/BE
BE = 10
Similarly, ...
1/2 = 6/CE
CE = 12
Then the unknown sides are ...
AE = AB + BE = 5 + 10 = 15 . . . cm
ED = CE + CD = 12 + 6 = 18 . . . cm
Answer:
angle b is 30 degrees
Step-by-step explanation:
a right angle is 90 degrees so you can do 90 -60 witch gets you 30 degrees
Answer:
Below in bold.
Step-by-step explanation:
Find the prime factors:-
126 = 2 * 3 * 3 * 7
234 = 2 * 3 * 3 * 13
So the GCF = 2 * 3 * 3 = 18.
The LCM = 2 * 3 * 3 * 7 * 13
= 1638.
Answer:

Step-by-step explanation:
Let
D(t) = the distance to the safe zone (measured in meters)
t = time (measured in seconds)
<u>Given:</u>
Rachel's rate = 24 meters per second
At
seconds
meters
<u>Find:</u> D(t)
Rachel's rate is the slope of the function D(t). Since the distance is decreasing when the time is increasing, the slope must be negative.
Hence, the function expression is

To find b, substitute
and 

So,
