Answer:
i think is c
Step-by-step explanation:
Sin(x) =1/10
So Cos x is not known
Hence Tan(x) = Sin(x)/Cos(x)
= 1/10/cos(x)
so cos(x)/10
Answer:
Bailey family's sprinkler was used for 35 hours and Harris family's sprinkler was used for 20 hours.
Step-by-step explanation:
Set up a system of equations.
Let be "b" the time Bailey family's sprinkler was used and "h" the time Harris family's sprinkler was used.
Then:

You can use the Elimination method. Multiply the first equation by -15, then add both equations and solve for "h":

Substitute
into an original equation and solve for "b":

Answer:
Step-by-step explanation:
First, we write the rental cost with each company:
Company A 
Company B 
Where m: miles travelled
Now, we need to find "number of miles in a day at which the rental costs for Company A and Company B are the same". This means Pa = Pb. Then:

Solving the equation for m by taking 0.2m and 60 on both sides:


Finally, dividing 0.5 on both sides:
