Answer:
w=1 5/24
Step-by-step explanation:
7/9-4/3w=-5/6
-4/3w=-5/6-7/9
-4/3w=-15/18-14/18
-4/3w=-29/18
w=-29/18:(-4/3)
w=29/18*(3/4)
w=29*3/18*4
w=29/6*4
w=29/24
w=1 5/24
Answer:
b. 45 N
Step-by-step explanation:
The sum of the forces exerted by the two miners = 25 + 20
= 45 N
Since after applying a force of 45 N by the two miners the cart remained stationary, it implies that a resistance force of at least 45 N acts against their push. Thus, the force exerted by the road could be equal to 45 N or greater than 45 N.
Probably, if the sum of the forces applied is 46 N, the cart would move. Which depends on the value of resistance force applied by the road. Thus, the appropriate answer from the given option is B.
Since the force applied on the cart equals the resistance force exerted by the road, the cart would not move.
Answer:
385 kilometers
Step-by-step explanation:
Divide 374 by 34 to get the unit price
Then multiply the unit price by 35
Answer:
A B A NOR B
F F T
F T F
T F F
T T F
Step-by-step explanation:
The logical operator NOR produces a result that is the negation of the logical operator OR.
The truth table for the logical operator NOR can be obtained by the negation of the results of the truth table for the logical operator OR.
Let A and B be the the logical values (or inputs). The operator OR produces a value of true if and only if at least one operand is true. The truth table for OR is:
A B A OR B
F F F
F T T
T F T
T T T
So, the truth table for NOR is:
A B A NOR B
F F T
F T F
T F F
T T F
Notice that the negation of OR (which is NOR) is obtained by changing the F by T and the T by F in the column of the results.
This table can also be writen with 0 instead of False and 1 instead of True.
Answer:
Step-by-step explanation:
The inequality will be split into two
It is know that, if a<b<c
Then a<b and b<c
-8<2x-4<4
Apply that to this
Then,
-8<2x-4. Equation 1
Also,
2x-4<4 equation 2
Solving equation 1
-8<2x-4
Add 4 to both side of the equation
-8+4<2x-4+4
-4<2x
Divide both sides by 2
-4/2<2x/2
-2<x
Note, if a is less than b, then, b is greater than a, e.g. 4 is less than 10, this implies 10 is greater than 4
Therefore,
-2<x
Then, x greater than -2
Equation 2
2x-4<4
Add 4 to both side of the inequalities
2x-4+4<4+4
2x<8
Divide both side by 2
Then,
2x/2<8/2
x<4
Therefore x is between -2 and +4.
