Two wheel gears are connected by a chain. The larger gear has a radius of 6 centimeters and the smaller gear has a radius of 4 centimeters. The smaller gear completes 28 revolutions in 15 seconds What is the linear velocity of each of the gears in centimeters per minute? The linear velocity of the smaller gear is 896π centimeters per minute. The linear velocity of the larger gear is 224π centimeters per minute. The linear velocity of the smaller gear is 224π centimeters per minute. The linear velocity of the larger gear is 56π15 centimeters per minute. The linear velocity of the gears is the same. The linear velocity is 56π15 centimeters per minute. The linear velocity of the gears is the same. The linear velocity is 896π centimeters per minute.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
