coldgirl [10]

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:

$\left \{ {{b+h=55} \atop {15b+40h= 1,325}} \right.$

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

$\left \{ {{-15b-15h=-825} \atop {15b+40h= 1,325}} \right.\\.............................\\25h=500\\\\h=\frac{500}{25}\\\\h=20$

Substitute $h=20$ into an original equation and solve for "b":

$b+20=55\\\\b=55-20\\\\b=35$

A truck can be rented from Company A for $100 a day plus $0.20 per mile. Company B charges $60 a day plus $0.70 per mile to

denis23 [38]

Answer:

Step-by-step explanation:

First, we write the rental cost with each company:

Company A $Pa = 100 + 0.2*m$

Company B $Pb = 60 + 0.7*m$

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:

$100 + 0.2*m = 60 + 0.7*m$

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

$100 + 0.2*m - 0.2*m - 60 = 60 + 0.7*m - 0.2*m - 60$

$40 = 0.5*m$

Finally, dividing 0.5 on both sides:

$m = 80$
