Instructions: Find the missing side of the triangle.<br> 48<br> 50

Lynna [10]

Answer:

x = 14

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

48 ^2 + x^2 = 50^2

2304+x^2=2500

x^2 = 2500-2304

x^2 =196

Taking the square root of each side

sqrt(x^2) = sqrt(196)

x = 14

Nolan is deciding between two truck rental companies. Company A charges an initialfee of $90 for the rental plus $2 per mile dri

kotegsom [21]

first we writte the information they are giving to us:

For company A:

initial fee = $90

rent per mile = $2

For combany B:

initial fee = $50

rent per mile = $3

Now for company A the equation that represent the charge in one mile will be: (where n is the number of miles)

$\begin{gathered} A=90+2(n) \\ A=90+2(1) \\ A=90 \end{gathered}$

And for company B:

$\begin{gathered} B=50+3n \\ B=50+3(1) \\ B=53 \end{gathered}$

Now to determine the number miles driven, that would make the cost of each company the same, we have to make A = B

$\begin{gathered} A=B \\ 90+2n=50+3n \\ \end{gathered}$

and finaly we can solve for n

$\begin{gathered} 90-50=3n-2n \\ 40=n \end{gathered}$

so if they drive for 40 miles the will pay the same
