Since One Radio in Davis Electronics requires 18 working resistors, then 2,145 radios will require resistors.
Now we know that one out of 22 resistors is defective. This means that the number of non defective or perfect resistors in a set of 22 resistors is 21.
So, obviously, if we pick a set of 40,370 resistors then the set of working resistors we will get is .
As can be clearly seen from the above calculations the required amount of working resistors is 38610 and the amount of working calculators available to us is 38535.
Thus, since the required amount of working resistors is greater than the amount of working resistors available, 40,370 resistors are not enough to assemble 2,145 radios.
Answer: the correct answer is 20
Step-by-step explanation:
The formula for determining the distance between two points on a straight line is expressed as
Distance = √(x2 - x1)² + (y2 - y1)²
Where
x2 represents final value of x on the horizontal axis
x1 represents initial value of x on the horizontal axis.
y2 represents final value of y on the vertical axis.
y1 represents initial value of y on the vertical axis.
From the graph given,
x2 = - 7
x1 = 5
y2 = - 7
y1 = 9
Therefore,
Distance = √(- 7 - 5)² + (- 7 - 9)²
Distance = √(- 12²) + (- 16)²
= √(144 + 256) = √400
Distance = 20
Answer:
( , - )
Step-by-step explanation:
4x - 5y = 20 → (1)
2x + y = 4 → (2)
subtract 2x fro both sides in (2)
y = 4 - 2x → (3)
substitute y = 4 - 2x into (1)
4x - 5(4 - 2x) = 20 ( distribute parenthesis and simplify left side )
4x - 20 + 10x = 20
14x - 20 = 20 ( add 20 to both sides )
14x = 40 ( divide both sides by 14 )
x = =
substitute this value into (3)
y = 4 - 2( ) = - = -
solution is ( , - )
Answer:
5 2/3 or 17/3
Step-by-step explanation:
If you simplify 1 8/9 you would get 17/9.
Next step is to divide 17/9 and 1/3
Use the keep,change,flip method.
17/9 x 3/1
Simply 3 and 9
17/3 x 1/1
The answer would be 17/3
If you want to make it a mixed number then it would be 5 2/3
