Hey there! :)
Answer:
Anna's number = 13.
Olga's number = 52.
Step-by-step explanation:
We can express this situation as an equation to solve for both of their numbers.
Let x be Anna's number
Let 4x be Olga's number
Their numbers sum up to 65, therefore:
4x + x = 65.
Begin by combining like terms:
5x = 65
Divide both sides by 5:
5x/5 = 65/5
x = 13 = Anna's number.
Find Olga's number by plugging 13 into 4x:
4(13) = 52. This is Olga's number.

A = 0.635
b = 8.57......
c = 17.5
d = 0.733....
put simply, the volume of a rectangular prism is just the product of all its 3 dimensions.
Step-by-step explanation:
We can set up the ration of the radian angle θ in your problem in terms of degrees given as the ratio: (Θ/2·pi) = (72/360), solving for Θ we get Θ = 1.26 radians. Then for the arc length s = Θ·r using this value gives s = 1.26·4 = 5.04
