Answer:
V = 5 m/h
Step-by-step explanation:
An aircraft carrier, traveled 9 hours at speed of 25 mph, that means the aircraft position from Hawaii (the start point of the journey) is:
25 m/h * 9 h = 225 miles far away from hawaii
When the aircraft has traveled 9 hours, the submarine has traveled 11 hours ( since its departure was 2 hours earlier ). They both traveled in opposite directions.
Then distance between the two vessels = d
d = 280 miles
280 = 225 miles (from the aircraft to hawaii ) + traveled distance for the submarine
And
Traveled distance by submarine d(s) = V* 11 miles/hour. where V is speed of submarine
Then
280 = 225 + 11*V ⇒ 11*V = 280-225 ⇒ 11*V = 55/11 mph
V = 5 m/h

Answer:
f(g(3) = 1
Step-by-step explanation:
f(g(3)
Step one: Plug in 3 for X
g(x)= 2x - 5 -> g(3) = 2 * 3 - 5
Step two : Solve ( By Using PEMDAS)
g(3) = 6 -5
g(3) = 1
Answer:
For #1 the answer is City C
Step-by-step explanation:
To find the value of anything with a sales tax simply multiply the cost by the tax.
$30 * 2.9%
$30 * .029
$0.87
Now that we have the sales tax, add it to the original cost.
$30 + $0.87 = $30.87
You can do this for each of the sales tax problems. Then compare the answers.
