Answer:
Andy's house to Billy's hometown 15 ways
Andy's house to Willie's hometown 2 ways.
Step-by-step explanation:
Andy's house to Billy's hometown there are 3 roads. There 5 road from billy's hometown to Willie's house . In total there will be 15 ways to travel which is calculated by 3 * 5. For traveling to Willie's hometown there will be two ways. There are two roads that are built to get to Willie's house.
Step-by-step explanation:
the total surface area is the sum of the 5 individual areas in the surface :
2 triangle sides (left and right).
1 back rectangle side
1 rectangle floor
1 inclined rectangle front side
to get the length of the baseline (Hypotenuse) of the right-angled triangles on the side. we use Pythagoras
c² = a² + b²
where c is the Hypotenuse (the side opposite of the 90° angle).
c² = 3² + 4² = 9 + 16 = 25
c = 5
so, now, we have everything we need.
the area of a triangle side (since it is right-angled) :
4×3/2 = 6
2 sides, that makes 12
the area of the back side
6×3 = 18
the area of the floor
6×4 = 24
the area of the inclined front side
6×5 = 30
so, the total surface area is
12+18+24+30 = 84

Answer: (C) 16
Step-by-step explanation:
Given : Number of sizes of self-stick notepads= 2
Number of colors = 4
Type 1 : The store packs the notepads in packages that contain 3 notepads of the same size.
i.e. By Fundamental principle of counting , we have
Number of different packages possible = Number of colors x No. of sizes
= 
Type 2: Notepads of the same size and of 3 different colors.
Choices for 3 different colors out of 4 : 
Again by fundamental principle :
Number of different packages possible = No. of choices for choosing 3 different colors x No. of sizes
= 
From Type 1 and Type 2 , the total number of different packages of the types described above are possible =8+8= 16
Hence, the correct answer is option (c) 16.
