Answer:
The number of ways are there to paint the four buildings is 48.
Step-by-step explanation:
I) let the first building be any color. Therefore the first building can be painted with any of the 4 colors.
Therefore the first building can be colored in 4 ways.
ii) the second building can be colored in 3 ways since it cannot be colored the
same color as the first building.
iii) the third building can also be colored in 3 ways.
iv) the last building can be colored in 2 ways because it cannot be the same color as the first building or the color of the adjacent building.
Therefore the total number of ways the buildings can be colored = 4 3 3 2 = 48.
Answer:
a) 0.04
b) 0.08
Step-by-step explanation:
Part a)
Divide the price of a pack by the number of stickers in a pack to get the price of one sticker.
$2/50 = $0.04/1
One stickers costs $0.04.
Part b)
Calculate 80% more than the price of one sticker.
80% in decimal form is 0.8. 80% more than the price is calculated with the factor 1.8.
($0.04)(1.8) = $0.072
Round 0.072 up because is rounded down, the profit is less than 80%.
0.072 => 0.08
Each sticker would need to be sold for $0.08.
Answer:
100°
Step-by-step explanation:
Supplementary means the sum of the angles is 180°
so we add 4+5 = 9
180/9 = 20
20 now we multiply according to the ratio
20x4:20x5
80:100
the measure of the largest is 100°
