If a 10 cm radius wheel rotates through 2 radians how many meters has it rolled?

1 answer:

6 0

2 radians = 2 full rotations
pi = 3.14

circumference of wheel = 2(pi)r
= 20 * 3.14
=62.8 cm
= 0.628m

meters rolled = 0.628 * 2
=1.256 m

To solve a Linear equation we need to find the slope:

-4-1 / -2-8 =1/2

now that we have the slope we can find our x and y
y-1=1/2(x-8)
y=x/2-3

To Find :

How many gallons of a 80% antifreeze solution must be mixed with 100 gallons of 20% antifreeze to get a mixture that is 70% antifreeze.

Solution :

Let, x gallons of 80% antifreeze solution is required :

So,

$(x \times 80) + ( 100 \times 20 ) = (x + 100 )\times 70\\\\8x + 200 = 7( x + 100)\\\\x = 500$

Therefore, 500 gallons of 80% antifreeze solution is required.
