Happy Paws charges $19.00 plus $3.50 per hour to keep a dog during the day. Woof Watchers charges $11.00 plus $4.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable h to represent the number of hours. help//

6.4 hours

Step-by-step explanation:

Hi, to answer this question we have to write an equation for each case:

Happy paws: the cost is equal to the fixed charge (19) plus the product of the charge per hour (3.50) and the number of hours (h).

Happy Paws Cost = 19+3.50h

Woof Watchers: the cost is equal to the fixed charge (11) plus the product of the charge per hour (4.75) and the number of hours (h).

Woof Watcher Cost = 11+ 4.75h

Since both costs must be equal:

Happy Paws Cost =Woof Watcher Cost

So:

19+3.50h = 11+ 4.75h

Solving for h:

19-11 = 4.75h-3.50h

8 = 1.25h

8/1.25 =h

h = 6.4 hours

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
