A lakeside hotel charges $12.50 per hour to rent a rowboat. The table shows the relationship between the number of hours,
h, and the total cost, c. With the information in the table, which expression can be used to find c?

Clear Check

h+23

h−25

12.50/h

12.50h

12.50h

Step-by-step explanation:

Each hour costs 12.50 to rent.

So, if you wanted to find a total cost, you would have to multiply 12.50 by the number of hours the boat was rented for.

12.50*h

12.50h

Hope this helps! :)

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
