Answer:
6 purses
Step-by-step explanation
1. Subtract 71 from 161 as that's how much Daniela needs to make to have 161, which is 90
2. Divide 15 by 90 as 15 is the profit, so the answer would be the amount of purses she needs to sell, then you get 6
Check
6 times 15, 90
71 + 90 = 161
Answer:

Step-by-step explanation:

It is two types of function.
- Exponential Growth: If function increase as value of x increase.
In this case, a>0 and b>1
- Exponential decay: If function decrease as value of x increase.
In this case, a>0 and 0<b<1
We need to choose exponential growth function.

Here a=0.75>0 and b=5>1
Therefore, This function is exponential growth.
Answer:
The angles 4, 5 and 6 are 36, 90 and 54 respectively.
Step-by-step explanation:
First, let's find the total number of parts:
2 + 5 + 3 = 10
The amount of degrees per part is 180 / 10 = 18.
Now, we multiply that factor to the ratio:

Thus, the angles 4, 5 and 6 are 36, 90 and 54 respectively.
Answer: yes, because any triangle with the ratio of whole number 3:4:5 is a right triangle
