x=6, add thirty to both sides 6 squared is 36, plus six is 42
Step-by-step explanation:
the average is the sum of all data points divided by the number of data points (5).
2 hours 17 minutes
2 hours 48 minutes
1 hour 53 minutes
2 hours 19 minutes
1 hour 38 minutes
------------------------------
8 hours 175 minutes
175 minutes = 2 hours 55 minutes
so, we need to add this to the 8 hours and get
10 hours 55 minutes
this we need to divide by 5 for the average time
(10 hours 55 minutes) / 5 = 2 hours 11 minutes =
= 2×60 + 11 = 120 + 11 = 131 minutes.
so, their score is 131.
We know that
If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment. (Intersecting Secant-Tangent Theorem)
so
ST²=RT*QT
RT=7 in
QT=23+7-----> 30 in
ST²=7*30-----> 210
ST=√210-----> 14.49 in
the answer is
RT=14.49 in
Answer:
Step-by-step explanation:
Apply the intersecting chord theorem.
DK × BK = AK × CK
12(4x+1) = 14(3 + 3x)
Expand brackets.
48x + 12 = 42 + 42x
Subtract 42x and 12 from both sides.
6x = 30
Divide both sides by 6.
x = 5
