The tires on your bicycle have a radius of 8 inches. How many rotations does each tire make when you travel 700 feet? Round your

Inessa [10]

"One rotation" would be the circumference of the wheel, which is

C = 2*pi*r, or (here) C = 2*pi*(8 inches) = 16*pi inches.

1 ft
Convert this to feet: 16*pi inches times ---------------
12 inches

Here "inches" cancels out and you are left with (4/3)pi ft.

So, one rotation of the wheel moves you and your bike forward (4/3)pi ft.

Divide this into 700 feet:

700 ft 2100
------------- = --------- rotations = 525 rotations (answer)
(4/3) pi ft 4

a )

Sum of the interior angles of any triangle equals 180° .

Thus :

$angle \: A + angle \: B + angle \: C = 180° \\$

$35° + 3(x+2)° + 52° = 180°$

$35° + 3x + 6° + 52° = 180°$

$3x + 93° = 180°$

Subtract sides 93°

$3x + 93° - 93° = 180° - 93°$

$3x = 87°$

Divide sides by 3

$\frac{3x}{3} = \frac{87}{3} \\$

$x = 29°$

________________________________

b )

$angle \: C = 3 ( x + 2 ) °$

$angle \: C = 3 ( 29+ 2 ) °$

$angle \: C = 3 ( 31 ) °$

$angle \: C =93 °$
