Answer: 53.4 cm
Step-by-step explanation:
The formula for circumference is C=2πr or C=πd. These equations are the same. Since the problem gives us the diameter, we'll go ahead and use C=πd.
C=(3.14)(17)
C=53.38=53.4 cm
Solution
-6x - 3y = 9 Add 6x to both sides
-6x + 6x - 3y = 9 + 6x
-3y = 9 + 6x Or more conventionally
-3y = 6x + 9 Divide by - 3
y = 6x/-3 + 9/-3
y = - 2x - 3
To solve this problem you must keep on min the information given in the problem shown above:
1- You have that
<span>
- The height reached by amal's rocket was 1/4 of the height reached by min's rocket.
- Amal's rocket REAched a height of 15 meters.
</span>
2. Therefore, let's call "x" to the <span>height reached by min's rocket. Then, you have:
</span>
(1/4)x=15
x/4=15
<span> Which equation could be used to find the height reached by min's rocket?
</span>
The answer is: x/4=15
So if you do 584/4 you get 146 which is the miles per hour, which is the rate of the jet. Also, the jet could fly 1,898 miles in 13 hours.
Answer:
The value is
Step-by-step explanation:
Generally the number of employee to survey(sample size) is mathematically represented as
![n = [ \frac{z * \sigma }{E} ]^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%20%5Cfrac%7Bz%20%2A%20%20%5Csigma%20%7D%7BE%7D%20%5D%5E2)
Here E is the margin of error which is given as E = 47
So substituting 1.645 for z and 155 for 
![n = [ \frac{1.645 * 155 }{47} ]^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%20%5Cfrac%7B1.645%20%2A%20%20155%20%7D%7B47%7D%20%5D%5E2)
=>
