Answer: 540
Step-by-step explanation:
Given : The owner of a stereo store wants to advertise that he has many different sound systems in stock.
Number of different CD players =6
Number of different receivers= 10
Number of different speakers = 9
We are assuming that a sound system consists of one of each .
Then by Fundamental principle of counting , we have
The number of different sound systems can he advertise = (Number of different CD players)x (Number of different receivers) x(Number of different speakers)
= 6 x10 x 9 =540
Hence, the number of different sound systems can he advertise =540
Answer:
Elimination
x = 2
y = -2
Step-by-step explanation:
Elimination
2x + 4y = -4
2x - y = 6
Subtract the second equation from the first
5y = -10
Divide both sides by 5
y = -2
---------------------
Substitute for y = -2 in the second equation
2x - -2 = 6
2x + 2 = 6
subtract 2 from both sides
2x = 4
Divide both sides by 2
x = 2
Answer:
<u>The simplified expression is y raised to the 2/8 power</u>
Step-by-step explanation:
Let's recall that one of the properties of fractional exponents is:
x ^ a/b = ᵇ√x ᵃ
therefore,
⁸√y² = y ^2/8
<u>The simplified expression is y raised to the 2/8 power</u>
These are all of the possible ratios:
- 1:3
- 8:24
-4:12
-2:6
