Answer:
The probability that the result of the spin is green and the coin lands tails up :
Step-by-step explanation:
As
the spinner has following three colors:
Also
the coin has two sides which are:
As the sample space is:
{red - head; red - tail; green - head; green - tail; yellow - head; yellow - tail}
So different colors with coin sides can be combined in total ways.
Therefore, the probability that the result of the spin is green and the coin lands tails up :
4 times 1 = 4
and 7 times 8 = 56
so 4/56 is your answer. Your teacher prolly wants you to simplify that answer.
11n - 3 = 9 + 5n
solving:
11n-3=9+5n
+3 +3
11n=9+5n
-5n -5n
6n=9
/6 /6
n= 3/2 (check if correct)
The length of AD in the parallelogram is 143 cm.
<h3>How to find the side of a parallelogram?</h3>
A parallelogram is a quadrilateral with opposite sides parallel to each other. The opposite angles of a parallelogram are equal. Two adjacent or consecutive angles of a parallelogram are supplementary.
Hence,
2x + 72 + 2x - 20 = 180
4x + 52 = 180
4x = 180 - 52
4x = 128
divide both sides by 4
4x / 4 = 128 / 4
x = 32
Therefore,
∠A = 2(32) + 72 = 64 + 72 = 136 degrees
z = 136°
Therefore,
AC = BC = BD = AD
AC = z + 7
AC = 136 + 7
AC = 143 cm
Hence,
AD = 143 cm
