Answer:
15.98 dollars
Step-by-step explanation:
its really easy
we need to subtract the total amount that she has spent from the total amount that she had in her purse
the total amount in Megan's purse=$45.12
total amount that Megan spent=$7.89+$21.25 =$29.14
now,
the exact amount that Megan has left = $45.12-$29.14=$15.98
A.) according to the graph, Austin appears to be burning 10 calories per minute. If you look at a perfect point on the graph, which I chose (50,5) and you do x over y or calories per minute, you get a unit rate of 10 calories per minute.
b.) Since you have already found the unit rate in question a, your slope would be 10.
Answer:
17π/2 square units
Step-by-step explanation:
The arc length is related to the angle and the radius by ...
s = rθ . . . . . r is the radius; θ is the central angle in radians, s is the length
The angle 20° is equivalent to (20°)×(π/180°) = π/9 radians. Then the radius can be found from ...
π/3 = r·π/9
3 = r . . . . . . . . . multiply by 9/π
The area of a sector is ...
A = 1/2r²θ
Here, the shaded sector has an angle measure in radians of 2π less the angle of the unshaded sector, π/9. That is, θ = 2 -π/9 = 17π/9. The area of the shading is ...
A = 1/2(3²)(17π/9) = 17π/2 . . . . square units
