Answer:
4.8%
Step-by-step explanation:
The population that grows with an annual percentage rate compounded continuously is given by: H = H° e^rt
Let the population be represented by H
The population reaches 1.1 times its previous size in 2 years.
So when t=2,
H = 1.1 H°
We substitute to obtain:
1.1 H° = H° e^r2
1.1 = e^2r
Take natural log to get:
In 1.1 = 2r
r = In 1.1 /2
r = 0.0477
Therefore the annual percentage rate is 4.8%
Answer:
10ft, 8ft and 6ft is the side measures of a right triangle.
Step-by-step explanation:
according to the pythagorus theorem the square of longest side ( hypotenuse ) should be equal to the sum of squares of remaining sides.
in triangle with sides ( 10ft, 8ft, 6ft )
the square of longest side = sum of squares of remaining sides,
10^2 = 100
8^2 + 6^2 = 64 + 36 = 100
hence it's the side measures of a right angled triangle.
and in other triangle the pythagorus theorem can't be applied hence they aren't right angled triangle

Answer:
Clarissa has a budget of $1,200 a month to spend for rent and food. She has already spent $928 this month. Let Clarissa has left $x amount spend for month. Hence,$272 left from her budget spend for month.
Answer:
$19
Step-by-step explanation:
If each person paid $9 , amount spent = $9 x 3
= $27 since they were three that went for the cake and coffee .
Given the total cost of the coffee was $8,
Cost of cake = $27 - $8
= $19
The total cost of the cake was $19
Answer:
The selling price of the puppy is $284.50.
Step-by-step explanation:
In the present case, the puppy's original selling price is $ 339.50. At this price a discount of $ 55 is made, that is, that amount is subtracted from the original price, modifying the sale price.
Therefore, since 339.50 - 55 results in 284.50, the puppy's sale price goes from $ 339.50 to $ 284.50, taking the aforementioned discount.
