Answer:
Circumference: 81.681 in; Area: 530.929 in
Step-by-step explanation:
To find circumference we use the formula pi x diameter. Which in this case is pi x 26 in, or approximately 81.681 in.
For the area, we use pi x r^2. r = 1/2 d, so r = 13in. Therefore, the area is equal to 169 x pi in, which is about 530.929 in.
For this problem, you know that the first walker will arrive 2 hours before the second, and increases his speed by 2 times the second walker. You also know there is a distance of 24 km. So up until some time x, the two walkers have to be going the same speed. If the first walker increases speed by two times the speed per hour, and arrives two hours earlier, then his initial speed will be 20 km/h, because after 2 hours, he will have an increase of 4 km/hr, and the second will have an increase of 2 km/h, thereby making the first arrive 2 hours earlier, if that makes sense.
Answer:
4400
Step-by-step explanation:
Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 80, 50, 110 i.e. 4400 smallest integer divisible by all numbers. Least common multiple (LCM) of 80, 50, 110 is 4400.
You cannot solve this equation, because you have no y or x values. However, you can change the equation to equal x.
Answer:
B. Sample error.
Step-by-step explanation:
Such type of error is called Sample error.
Sample error occurs when
Sample error is a statistical error when an expert fails to choose a sample which symbolizes the whole data population and the outcomes of the sample do not reflect the outcomes from the whole population.
