A wheel whose diameter is 3 feet rolls a distance of 45 feet without slipping. Through what radian angle did the wheel rotate? 1) 30 2) 25 3 30 pi 4) 12 pi

1) 30

Step-by-step explanation:

We need the radius of the wheel, we know that the radius is half the diameter, therefore:

r = d / 2 = 3/2 = 1.5

the angle is equal to the distance traveled (s) divided by the radius, thus:

° A = s / r =

° A = 45 / 1.5

° A = 30 radians

Through the radiation angle of 30 radians the wheel turned

therefore the answer is 1) 30

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
