\sf Speed \:  of \:  the  \: car = 70 km/h

\sf Time \:  taken = 3 \:  hours \:  30  \: minutes

a = 3.5

Step-by-step explanation:

\frac{a}{sin(A)}  = \frac{c}{sin(C)} \\\\a = \frac{csin(A)}{sin( C )} \\\\a = \frac{3 sin(63^{o} )}{sin(49^{o} )} \\\\a = 3.5

Answer:

Step-by-step explanation:

11)  y = -1x - 2

12)  y = -(3/2)x + 3

13)  y = 3x - 2

14)  y = (3/4)x + 1

15)  y = (1/2)x + 1

16)  y = -(2/5)x

17)  y = 7x + 2

18)  y = (4/3)x - 4

ohaa [14]
Cory brings five 1-gallon jugs of juice. 

5 jugs * 1 gallon per jug = 5 gallons of juice total

Knowing that the cups Cory is using to serve can hold 8 fluid ounces, we are asked to figure out how many cups Cory can serve.

1 gallon = 128 fluid ounces
5 gallons = x fluid ounces

Let's set up a proportional equation.

1/128 = 5/x

Now, we can use cross products to simplify and solve.

1 * x = 128 * 5

x = 640 fluid ounces.

Therefore, Cory has a total of 640 fluid ounces.

To find out how many cups he can serve, we need to divide the total amount of juice he has (640 oz) by the amount of juice in each cup (8 oz).

640 / 8 = 80

Thus, Cory can serve 80 cups of juice at parent night.
