Answer:
the value of 43.7891 will obviously be 43.7891
20 dollars because you divide the 380 in half get 190 take 190 and subtract the 30 dollar discount left with 160 then you subtract her payment of 140 and your left with 20 dollars
Answer:
This is a geometric sequence. The first term is the max height of the first curved path, which is 0.5. The second one is 52% of that meaning that it is 0.52 times the first term. The third term is 0.52 times the second term. Thus, in this geometric sequence,
Step-by-step explanation:
a = 0.5
r = 0.52
You will need to use the relation a_n = a \cdot r^{n-1}

Step-by-step explanation:
for this question you will need to do probability trees and take note that the card was not replaced after it had been taken out of the packet meaning that there is two less card in the packet.
i) 2/4 = 1/2
ii) 2/18 = 1/9
iii) 2/6 = 1/3

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
141° is an exterior angle, thus
x + 24 + 2x + 12 = 141 , that is
3x + 36 = 141 ( subtract 36 from both sides )
3x = 105 ( divide both sides by 3 )
x = 35

The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
2x - 9 + 3x + 2x = 180
7x - 9 = 180 ( add 9 to both sides )
7x = 189 ( divide both sides by 7 )
x = 27
