Answer:
The cost to buy 100 shares in ODX group Inc and 300 shares peer Comms Lts is
Step-by-step explanation:
From the chat we that the cost of 100 ODX shares is
The cost of 100 peer Comms Lts is
Hence the cost 300 peer Comms Lts is
Now the cost of 100 shares in ODX group Inc and 300 shares of peer Comms Lts is mathematically evaluated as
Answer: 1. x= 10-3y/2. 2. x= 5(4-y)/4
Step-by-step explanation: 1. Subtract 3 y from both sides. Then. divide both sides by 2. 2. Subtract 5 y from both sides. Divide both sides by 4. Factor out the common term 5.

Answer:
A
Step-by-step explanation:
So we want to find the tangent of Angle QSR.
First, note that Angle QSR and Angle TSQ forms a supplementary angle. Thus:
We already know that TSQ is 150, thus:
Subtract:
So, QSR is 30 degrees.
Find tangent of 30 degrees.
1) If you know the unit circle:
At 30 degrees, our coordinate is:
So, our answer would be:
Simplify:
2) If you don't know the unit circle.
Recall that 30-60-90 is a special right triangle.
The side opposite to 30 is x, the side adjacent to 30 is x√3, and the hypotenuse is 2x.
Therefore, tangent of 30 is opposite over adjacent. Thus:
Substitute x for opposite and x√3 for adjacent. Thus:
Remove the x:
Multiply both layers by √3. So:
Our answer is A :)
Answer:
9) 28% decrease
13) 100% decrease
15) $9.90
17) 272 pages
18) 42 members
19) $27,840
20) 1,863 songs
Step-by-step explanation:
9) Subtract 68 from 95 and you get 27.
Divide 27 by 95 and you get 0.284...
Multiply 0.284... times 100 and you get 28.4.
Round to 28%
13) If a number goes from itself to zero, it's a 100% decrease
15, 18, 20) Divide percent by 100.
Multiply the percent by the initial number.
Add the new number to the initial number
17 and 19) Do everything you did in 15, 18, and 20, but instead of adding the new number to the initial number, subtract it to the initial number
