Answer: w lesser than or equal to 4
Step-by-step explanation:
Dwight and Walt are building model cars.
Let d = the number of models built by Dwight.
Let w = the number of models built by Walt.
Dwight builds 7 fewer models than 4 times the number Walt builds. This can be expressed as
d = 4w - 7 - - - - - - - - - 1
Dwight builds at most 9 models. This is expressed as
d lesser than or equal to 9
From equation 1
d = 4w - 7
4w = d + 7
w = (d+7)/4
Assuming Dwight built 9 models
w = (9+7)/4 = 4
Therefore,
Walt builds at most 4 models. It is expressed as
w lesser than or equal to 4

Your answer would be: 4.62e-11
Answer:
8.37
Step-by-step explanation:
20 knots * 1.151 = 23.02 miles per hour There are 1,760 yards in a mile and 3,600 seconds in an hour. So, we multiply 23.02 * (1,760 / 3,600) which equals
11.2542222222 yards / second
