Answer:

2 hours

Step-by-step explanation:

For if you start at 1 hour you end up with one bus 45 miles away from the school and the other 40 miles. If you then add these then you find out how far apart they are which is 85 at this point and time. If you do another hour the bus going 45 is now 90 miles away from the school. The other one will be 80. After you add these two number to find how far apart they are you end up with 170.

Answer:

  x^2 +(y -61)^2 = 625/36

Step-by-step explanation:

The graph of the above equation is attached.

If the circumference of the wheel is 25π/3 feet, the diameter is ...

  d = C/π = (25/3π)/π = 25/3 . . . feet, about 8.33 feet

The radius will be half that value, or 25/6 feet.

For a center point (h, k) and radius r, the equation of a circle is ...

  (x -h)^2 +(y -k)^2 = r^2

You want the center to be more than 60 feet from the ground, so we can make it be 61 feet. The horizontal location is not specified, so we can make it zero.

This means we apparently want the equation for a circle of radius 25/6 feet with a center that is (x, y) = (0, 61). The equation of this circle is ...

  x^2 +(y -61)^2 = 625/36

Which equation is an identity?
nika2105 [10]

The answer is C. 10p+6-p=12p-3(p-2)

because if you substitute any number for p, it will always equal each other

a. 5m-6=5m+7m

5(3)-6=5(3)+7(3)

15-6=15+21

9=36

b. 6(3)-5=7(3)+5-3

18-5=21+5-3

13=23

c. 10(3)+6-3=12(3)-3(3-2)

30+6-3=36-3

33=33

d. 3(3)+2=3(3)-2

9+2=9-2

11=7
