Area of sector=sectorfraction times area
sector fraction=angle/360
area=pir^2
r=10
area=pi10^2=100pi
so
5pi/100pi=xdeg/360
1/20=x/360
times both sides by 360
18=x
answer is 18 degres

Answer:
1<X<=6
Step-by-step explanation:
seven less than six times her number is between negative one and twenty-nine (inclusive).
The above statement can be expressed mathematically thus;
Let the number be x
6x-7= (-1 ,29]
Hence 6x-7 = -1=>6x=6=>x=1 or
6x-7= 29=>6x=36=>x=6
Hence 1<X<=6
Answer:
1363.6
Step-by-step explanation:
let the basic salary be = x
10% of x = 10/100x
So the equation = x + 10/100x = 1500
= x + 0.1x = 1500
= 1.1x = 1500
= x = 1500/1.1
= x = <u>1363.6</u>
