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:
x = 111
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 7 , then
sum = 180° × 5 = 900
Sum the interior angles and equate to 900
x + 139 + 121 + 125 + 126 + 158 + 120 = 900
x + 789 = 900 ( subtract 789 from both sides )
x = 111
Answer:
its is x=0
Step-by-step explanation:
10x = 5 Answer: x = 1/2
−5 = x + 6 Answer: x = -11
22 = 22x Answer: x = 1
0 = −7x Answer: x = 0
−x = 7 Answer: x = -7
x/4 = 1/2 Answer: x = 2
x/5 = 20 Answer: x = 100
x/-2 = -5 Answer: x = 10
5x = 55 Answer: x = 11
−3x = 18 Answer: x = -6
12 = x -6 Answer: x = 18
Answer:
150 = x
Step-by-step explanation:
We can use a ratio to solve
100 batches x batches
------------------- = ---------------------
8 hours 12 hours
Using cross products
100 * 12 = 8x
1200 = 8x
Divide by 8
1200/8 = 8x/8
150 = x
