Answer:
m = 3 1/3
Step-by-step explanation:
since the triangles are similar then ΔATR must be isosceles also
we can set up this proportion:
AR/TR = EF/EG
12/8 = 5/m
cross-multiply to get:
12m = 40
m = 40/12 or 20/6 which is 3 1/3
We have cos( x - y ) = cosxcoy + sinxsiny <=> cos ( π - x ) = cosπcosx + sinπsinx <=> cos ( π - x ) = (-1)cosx + 0sinx = -cosx;
Answer:
after 2 months the total cost will be the same.
Step-by-step explanation:
21+20x=27+17x subtract 17x on both sides because its the lowest coefficient
20x- 17x = 3x 17x-17x= cancel out
subtract 21 on both sides because its the lowest number
21-21= cancel out. 27-21=6
divide the coefficient by both sides
3x/3= x
6/3= 2
x=2
B) The probability that both marbles are purple is 2.22%.
C) The probability that you pick at least one purple marble is 98%.
<h3><u>Probability</u></h3>
The question is incomplete, since the number of marbles of each color in the bag is missing: 3 blue, 5 green, and 2 purple marbles.
Now, to answer the questions, the following calculations must be done:
- B) 2/10 x 1/9 = X
- 0.2 x 0.11111 = X
- 0.022222 = X
- X x 100 = 2.22
- C) 100 - (2/9x9) = X
- 100 - 2 = X
- 98 = X
