1.To find the triangle area is base x height : 4.33 x 5=21.65
Perimeter : 5+5+5=15
2. 6•3=18+(3•2)=18+6=24=area
16=perimeter
3. Not sure
4. 12•17=204=area
Perimeter : 13+17+17=47
Hoped I helped!
Answer:
1) 20: 25
2) 15: 3
Step-by-step explanation:
For this case we have the following variables:
x: Quantity of orange picks
y: Quantity of green picks
According to the statement, we have the following proportion:
, that is:
![5x = 2y](https://tex.z-dn.net/?f=5x%20%3D%202y)
If there are 21 picks, then:
![x + y = 21](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%2021)
So, we have two equations with two unknowns:
----> (1)
----> (2)
From (2):
![x = 21-y](https://tex.z-dn.net/?f=x%20%3D%2021-y)
Substituting x in (1):
![5 (21-y) = 2y\\105-5y = 2y\\105 = 7y\\](https://tex.z-dn.net/?f=5%20%2821-y%29%20%3D%202y%5C%5C105-5y%20%3D%202y%5C%5C105%20%3D%207y%5C%5C)
![y = \frac{105}{7}\\y = 15](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B105%7D%7B7%7D%5C%5Cy%20%3D%2015)
Substituting
in (2) and clearing x, we have:
![x + 15 = 21](https://tex.z-dn.net/?f=x%20%2B%2015%20%3D%2021)
![x = 21-15](https://tex.z-dn.net/?f=x%20%3D%2021-15)
![x = 6](https://tex.z-dn.net/?f=x%20%3D%206)
So, there are 6 orange picks
Answer:
6 orange picks
The answer would be p=7/2 or p=3.5
