A tire on a toy car has a diameter of 8 cm if the toy car travels 12,560 cm approximately how many times does the tire rotate? U
Marina86 [1]

Answer:

The number of rotations completed by tire  = 500.

Step-by-step explanation:

The diameter of the tire of toy car = 8 cm

Now, DIAMETER = 2 x RADIUS

So, radius of the tire =  D/2  = 8/2 = 4 cm

Now, Circumference of the Circle = 2πr

= 2 x 3.14 x 4 = 25.12 cm

Now, \textrm{Total  number of rotations}  = \frac{\textrm{Total Area covered}}{\textrm{Area covered in 1 rotation}}

= \frac{12,560}{25.12}  = 500

The number of rotations completed by circle = 500.

Kelli and Karl each have a job. Kelli earns $20 an hour. She also receives a $100 weekly bonus.
Firlakuza [10]
Answer:   When they work 10 hours each, they both make $300.

kelli    y = 20x + 100
karl    y = 25x + 50

substitution:

y = 20x + 100

25x + 50 = 20x + 100
-20x  -50    -20x   -50
--------------------------------
5x = <span>50 
</span>5       5

x = 10

(Then plug into any equation)
y = 25x + 50
y = 25(10)  + 50
y = 300

When they work 10 hours each, they both make $300.
