Answer:
store B, C, and D
Step-by-step explanation:
Distance between two points P(x1,y1), Q(x2,y2):
D=sqrt((x2-x1)^2+(y2-y1)^2)
Polygons are generally named in order along the perimeter, so that for a rectangle ABCD, AC or BD are diagonals.
Here, we need the distance between points A(4,3) and C(-4,-2)
Applying the above formula for distance between two points,
D=sqrt((4-(-4))^2+(3-(-2))^2)=sqrt(8^2+5^2)=sqrt(64+25)=sqrt(89)
Answer:
3/4°
Step-by-step explanation:
84+72+108+60+156= 480 people
480*x= 360°
x= 360°/480= 3/4°
Answer:
100 girls
Step-by-step explanation:
The ratio of boys : girls is 2 : 5.
In other words, boys are 2 parts of the school while girls are 5 parts of the school.
Since there are 40 boys, 2 parts of the school is 40. Thus:
![2p = 40\\p = 20](https://tex.z-dn.net/?f=2p%20%3D%2040%5C%5Cp%20%3D%2020)
1 part is 20.
Since there are 5 parts girls, there are
![5p = 5*20 = 100](https://tex.z-dn.net/?f=5p%20%3D%205%2A20%20%3D%20100)
100 girls.
