Answer:
A
Step-by-step explanation:
1 yard = 36 inches
1 feet = 2 foots = 24 inches
First time, she's got 5315 inches, second time is 5868 inches
5315 + 5868 = 11183 inches
11183 : 36 = 310.638888889 inches
Change it and we have answer A, 311 yards 11 inches
This is already in slope intercept from. because the slope is -2 and the y intercept is 4. so if you put it in stander form you would get y=-2x+4
Answer:0.2588
Step-by-step explanation:
To find the exact value for
Sinpi/12
pi=180°
So
Sin 180/12
Sin15°
=0.2588
Since

we know our function is

.
To solve, substitute the given value:
Answer:
The correct options are a,b.
Step-by-step explanation:
The area of sector of a circle equals
Area of a sector = 
where
is the angle subtended at the center by the sector
is the radius of circle
This indicates that area of the sector depends on:
1) Radius of circle
2) Angle subtended at the center by the sector
3) Area of sector does not depend on pi.
Also if we know the area of the sector only we cannot calculate area of area of whole triangle as we need one more information either angle of the sector and vice versa.
