Answer:
Jacob: $80
Hilary: $120
Brian: $40
Step-by-step explanation:
Let the amount Brian gets be $x.
Amount Jacob gets= $(2x)
Amount Hilary gets= $(3x)
Total amount of money= $x +$(2x) +$(3x)= $(6x)
$240= $(6x)
6x= 240
x= 240÷6
x= 40
Now substitute the value of x to find out the amount of money each one gets.
Brian gets $40.
Amount Jacob gets= 2(40)= $80
Amount Hilary gets= 3(40)= $120
The diameter of the coaster is 5 cm.
Step-by-step explanation:
Given,
The area of the circle = 19.63 sq inch
To find the diameter, we need to find the radius
Formula
The area of a circle with radius(r) = π sq cm
According to the problem,
π = 19.63
or, =
= 6.2459
or, r = = 2.499 (approx)
= 2.5 cm
Hence the diameter of the circle = 2 × 2.5 cm = 5 cm
