Answer:
165 pumas
Step-by-step explanation:
Using the formula given:
where n = number of pumas after a specific number of years
a = initial number of pumas = 24
r = rate = 12% = 0.12
t = number of years = 17
We obtain the number of pumas after 17 years to be:
≅ 165 pumas
After 17 years, the number of pumas in the park was 165.
Answer:
Each mixture has the same amount of salt for every 1 cup of water.
Step-by-step explanation:
It is provided that:
- Nia mixed 1 teaspoon salt with 3 cups warm water.
- Trey mixes 1 /2 teaspoon salt with one and 1/2 cups warm water.
The ratio of the number of teaspoons of salt to the number of cups of water is 1 : 3 in Nia's solution.
On dividing the amount of salt and the amount of water by 3, the ratio will be the same.
Thus 1 : 3 is equivalent to the ratio , which means that Nia's solution has
teaspoon of salt for every cup of water.
The ratio of the number of teaspoons of salt to the number of cups of water is in Trey’s solution.
On dividing the amount of salt and the amount of water by , the ratio will be the same.
So Trey’s ratio is also equal to the ratio .
Since each mixture has the same amount of salt for every 1 cup of water, they are equally salty and taste the same.
