Alternatively you can write it as;

Step-by-step explanation:
One time service fee=$99
Rate of service=$50/hour
let unknown hours=x
Therefore the equation is

or you can further simplify it to:

And you can then solve for x to be 9 hours.
Answer:
22.36 mile.
Step-by-step explanation:
Please see attached photo for explanation.
In the attached photo, y is the distance between starting point and the end point.
Thus we can obtain the value of y by using the pythagoras theory as show below:
Note: y is the longest side other wise known as the Hypothenus.
y² = 10² + 20²
y² = 100 + 400
y² = 500
Take the square root of both side
y = √500
y = 22.36 mile
Therefore, the distance between the starting point and the end point is 22.36 mile
should be (5,-5) just because its in the 5 then when its going down its -5
the probability of a boy getting picked is 7/10 or 7%and the probability of a girl getting picked is 6/10 or 6%
Answer:
B
Step-by-step explanation:
To answer this, we need to see the to see to the fact that they are both in the same unit before we can take the ratio.
Firstly, we know that 1 foot = 12 inches. 9 feet would this be 9 * 12 = 108 inches.
Now we are told to get the ratio of length of car to length of model.
This means 108:6 = 18:1
