Answer:
The maximum speed of Hal's airplane in still air is:
The speed of the wind
Step-by-step explanation:
Remember that the velocity v equals the distance d between time t.
and 
The distance that Hal travels when traveling with the wind is:
miles
Where v is the speed of Hal and c is the wind speed.
The distance when traveling against the wind is:
miles
Now we solve the first equation for v
Now we substitute the value of v in the second equation and solve for c
Then:
The maximum speed of Hal's airplane in still air is:
The speed of the wind
Answer:
8 -------$ 12
Step-by-step explanation:
There are different weights of oranges at a farmer’s market given in the question. Two oranges that is three dollars. So one orange will be of one point five dollars. Then five will be equal to seven point five dollars. Much easier form of calculation that is eight equal to seven point five plus one point five that is added three times. This gives the final value of eight oranges that is twelve dollars.
8------12$
2 orange = 3$
So 1 = 1.5$
5 = 7.5$
8 = 7.5 + 1.5 + 1.5 + 1.5
8 oranges = 12$
Answer:
$72.15
Step-by-step explanation:
x= pounds of steak
$
= money spent on steaks
If Neil buys 7.5 pounds of steak then x =7.5
$9.62(7.5) = $72.15
Given
Divide it by (x+1) using synthetic division, as shown below
The green line is a minus sign.
Thus,
Therefore, since the remainder is different than zero, (x+1) is not a factor of 4x^2+2x-5
At least 8 routes, at most 63 routes
