Answer:
The error interval for x is:
![[15.375,15.384]](https://tex.z-dn.net/?f=%5B15.375%2C15.384%5D)
Step-by-step explanation:
In order to determine the error interval for x, We have to get the all the number which could be rounded off to
.
These number can be listed in order such as:
15.375 15.376 15.377 15.378 15.379 15.380 15.381 15.382 15.383 15.384
Therefore, the error interval for x is:
![[15.375,15.384]](https://tex.z-dn.net/?f=%5B15.375%2C15.384%5D)
13 times 4 is 52
9 times 4 is 36 plus the 20 it takes for reservation
So the maximum amount would be 4
Answer:
It will cost $427.04 to paint deck and it will cost 958.485 to add fencing around deck
Step-by-step explanation:
Diameter of swimming pool = 27 feet
Radius of pool r=
Surrounding the pool is a deck that extends 5 feet from the edges of the pool
Outer radius R = 13.5+5=18.5
Area of deck = Outer area - Inner area
Area of deck =
Area of deck = 
Area of deck = 
Cost of painting 1 sq.feet = $0.85
Cost of painting 502.4 sq.feet = 
Perimeter of deck = 
Cost of fencing 1 foot = $8.25
Cost of fencing 116.18 foot = 
Hence it will cost $427.04 to paint deck and it will cost 958.485 to add fencing around deck
Answer:
Option A - 
Step-by-step explanation:
Given : For the sequence 
To find : Identify the values of following?
Solution :
The nth term of the sequence is 
Substitute n=0,1,2 and 3
When n=0,



When n=1,



When n=2,



When n=3,



Therefore, The value is 
So, Option A is correct.
Speed traveling west = x - 10 km /hr
275 / ( x-10) - 300 / x = 1/2
275 *2x - 300 (x-10)*2 = ( x-10) *x
550x - 600x +6000 = x^2 -10x
x^2 +40x - 6000 = 0
( x -60) ( x+100) = 0
x = 60
ANSWER East = 60 km/ hr West = 50 km /hr
CHECK
300 /60 = 5 hours
275 /50 = 5.5 hours
