Answer:
50
Step-by-step explanation:
any thing passed 5 is rounded up for example, 35 rounds up to 40. 42 rounds to 40 since it's under 45
Answer:
W= -6
Step-by-step explanation:
-4w = -5 + 29
-4w = 24
Divide both sides by -4
=
W = -6
A common ratio is basically a ratio of next sequence and the sequence you want
To find a common ratio of geometric sequence, we usually define 'r' as common ratio.
![\displaystyle \large \tt{r = \frac{next \: \: sequence}{the \: \: sequence \: \: you \: \: want} }](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%5Clarge%20%5Ctt%7Br%20%3D%20%20%5Cfrac%7Bnext%20%20%5C%3A%20%20%5C%3A%20sequence%7D%7Bthe%20%5C%3A%20%5C%3A%20sequence%20%5C%3A%20%20%5C%3A%20you%20%5C%3A%20%20%5C%3A%20want%7D%20%7D)
For example, I want to focus on -14 and the next sequence would be -84.
Hence,
![\displaystyle \large{r = \frac{ - 84}{ - 14} }](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%5Clarge%7Br%20%3D%20%20%5Cfrac%7B%20-%2084%7D%7B%20-%2014%7D%20%7D)
Thus, r is 6 because both numerator and denominator are negative. negative divides negative = positive.
Or you want to choose -84, then the next sequence would be -504.
![\displaystyle \large{r = \frac{ - 504}{ - 84} }](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%5Clarge%7Br%20%3D%20%20%5Cfrac%7B%20-%20504%7D%7B%20-%2084%7D%20%7D)
Then r would still be 6. Since both ways have r as 6 and this proves that the sequence is geometric.
Hence, the common ratio is 6.
Answer:
The length is 8
Step-by-step explanation:
Answer:
263.76 feet
Step by step explanation:
Circumference of a circle = pi x d
Given
Diameter d =84 and
Pi = 3.14
Therefore
Circumference = 3.14 x 84
= 263.76 feet
