Answer:
Step-by-step explanation:
(a) The appropriate formula is C = 2πr. Here r = 14 cm, so
C = 2π)14 cm = 28π cm, or (if we take π to be 22/7), C = 88 cm²
(b) We use the same circumference formula: C = 2πr and solve it for r before inserting numeric values:
C 132 m 7(132 m)
r = -------- and in this case, r = ------------------- = ------------- = 21 m
2π [ 2 * (22/7) ] 44
Answer:
![9x- 60=10](https://tex.z-dn.net/?f=9x-%2060%3D10)
Step-by-step explanation:
Given
![\frac{3}{4}x - 5 = \frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7Dx%20-%205%20%3D%20%5Cfrac%7B5%7D%7B6%7D)
Required
Rewrite to remove fractions
The denominators in the above expression are 4 and 6.
So, first we take the LCM of 4 and 6
![LCM = 12](https://tex.z-dn.net/?f=LCM%20%3D%2012)
Next, multiply both sides of the equation by this LCM (12)
![12 ( \frac{3}{4}x - 5) = \frac{5}{6} * 12](https://tex.z-dn.net/?f=12%20%28%20%5Cfrac%7B3%7D%7B4%7Dx%20-%205%29%20%3D%20%5Cfrac%7B5%7D%7B6%7D%20%2A%2012)
![12 * \frac{3}{4}x - 12 *5 = \frac{5}{6} * 12](https://tex.z-dn.net/?f=12%20%2A%20%5Cfrac%7B3%7D%7B4%7Dx%20-%2012%20%2A5%20%3D%20%5Cfrac%7B5%7D%7B6%7D%20%2A%2012)
![3 * 3x- 60=5 * 2](https://tex.z-dn.net/?f=3%20%2A%203x-%2060%3D5%20%2A%202)
![9x- 60=10](https://tex.z-dn.net/?f=9x-%2060%3D10)
You have to do 5+5 cross them out then add 5+5 on the other side, bring y down and your answer is y<10 x
For the second one, you do 2-2 which is 0 so your answer would be y
Answer:
6? i hope this helps some! :)
Step-by-step explanation:
each has 6 in between the number
5 or 6 p there is a possibility of there being 6
7 or 8 there is at least 6 in this cup
6 or 7 there is at least 6 in this cup
7 or 5 there is a possibility of there being 6
