Answer:
540 m
Step-by-step explanation:
The building of the Blue Museum of Barcelona is triangular and each side of the building is 180 m.
This means the building is shaped as an equilateral triangle.
We need to find the total distance traveled if we go round the building, that is, its perimeter.
The perimeter of an equilateral triangle is given as:
P = 3L
where L = length of the side of the building = 180 m
The total distance traveled if we go round the building will be:
P = 3 * 180 = 540 m
We would need to go 540 m to travel around the building completely.
Answer: Approximately 25187 animals of this species will be left in 2025
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
y = b(1 - r)^x
Where
y represents the population of animals after x years.
x represents the number of years.
b represents the initial population of animals.
r represents rate of decay.
From the information given,
b = 200000
r = 4.5% = 4.5/100 = 0.045
x = 2025 - 1980 = 45 years
Therefore,
y = 200000(1 - 0.045)^45
y = 200000(0.955)^45
y = 25187
Answer:
On Saturday, a local hamburger shop sold a combined total of 312 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold, How many hamburgers were sold on Saturday?
Step-by-step explanation:
x is the hamburgers
x times 3 is the cheeseburgers
answer x=78
check work 78 x 3 =234
78 + 234 = 312
