Hi there!
We can find the area of a triangle with the formula:
![area = 0.5 \times base \times height](https://tex.z-dn.net/?f=area%20%3D%200.5%20%5Ctimes%20base%20%5Ctimes%20height)
Filling in this formula gives us the following answers.
Triangle 1
![area = 0.5 \times 5 \times 8 = 20](https://tex.z-dn.net/?f=area%20%3D%200.5%20%5Ctimes%205%20%5Ctimes%208%20%3D%2020)
Triangle 2
![area = 0.5 \times 7 \times 9 = 31.5](https://tex.z-dn.net/?f=area%20%3D%200.5%20%5Ctimes%207%20%5Ctimes%209%20%3D%2031.5)
Triangle 3
Answer:
sorry
Step-by-step explanation:
Answer:
What are we finding for X?
Step-by-step explanation:
Answer:
680 girls and 850 boys
Step-by-step explanation:
the ratio of girls is 4/9
then we can find the number of girls (G) in the group of 1530 students using proportions:
4 / 9 = G / 1530
solving for G by multiplying both sides of the proportion by 1530, we get:
G = 4 * 1530 / 9 = 680
So there were:
680 girls and 1530 - 680 = 850 boys
Bro same I don't know how to do this maybe cause I don't even care anymore but its OK I hope you got the answer already
