Assume Alan's brother has x coins before Alan gave him 48 coins
x+48=1.4x (increased by 40%)
0.4x=48
x=120
120+140=260
answer is 260 coins
4:
V= L x W x H
V= 8.2ft x 9.4ft x 10.7 ft
V= 824. 756 ft3 or 824.8ft3
The volume of the cube is 824.8 ft3. The answer is F.
Answer:
5
Step-by-step explanation:
Having the angle in radians and the diameter of the circle we can easily calculate the length using the following expression
Length = angle(radians)*diameter/2
With this expression we can easily deduce the perimeter of a circle (length of the full arc)
Length = Perimeter = 2*pi*r
There is only one operation involved in this process
