Answer:
h=15,7 ft
l1=19.8
l2=l1=19.8
Step-by-step explanation:
A=(b×h)/2
110=x×14/2
x×14=220
x=220/14=15,7
h=15.7 ft
l=rad(144+246.7)=19,8
l1=l2=19,8
Answer:
Answer is (b) The worker with 40 hours of training is paid $1400 per month
Answer:
Step-by-step explanation:
look at 2=x-y=2
move this term to the left (2)
it becomes 2=x-y+2=0
and thats your results
Examples: x^2-2x=-1, 3x-x-x+a-a=5, (x^2-1)/(x+1), 2x-(x+x)
Answer:
.
Step-by-step explanation:
It is given that a number, x, rounded to 2 significant figures is 1300.
It is possible if,
1. The value of x is greater than of equal to 1250 and less than or equal to 1300.
i.e.,
...(1)
2. The value of x is greater than of equal to 1300 and less than 1350.
i.e.,
...(2)
On combining (1) and (2), we get

1350 is not included in the error interval for x.
Interval notation is
.
Therefore, the error interval for x is
.
