Answer:
The approximate length of the diagonal walkway is 21.21 meters
Step-by-step explanation:
we know that
Applying the Pythagorean Theorem in the square park, find out the the approximate length of the diagonal walkway
so
![c^2=a^2+b^2](https://tex.z-dn.net/?f=c%5E2%3Da%5E2%2Bb%5E2)
where
c is the diagonal of the square
a and b are the length sides of the square
we have
![a=15\ m\\b=15\ m](https://tex.z-dn.net/?f=a%3D15%5C%20m%5C%5Cb%3D15%5C%20m)
substitute
![c^2=15^2+15^2\\c^2=450\\c=21.21\ m](https://tex.z-dn.net/?f=c%5E2%3D15%5E2%2B15%5E2%5C%5Cc%5E2%3D450%5C%5Cc%3D21.21%5C%20m)
therefore
The approximate length of the diagonal walkway is 21.21 meters
Answer:
a= -5/8
b= -4/7
c= -2/5
Step-by-step explanation:
8a + 5 = 7b + 4 =5c + 2
I'm not sure what you want with this incomplete question, but I assume it's to find the values of a, b, and c.
Therefore, to find the value of a,
8a+5=0
8a= - 5
a= -5/8
7b + 4=0
7b = - 4
b= -4/7
5c + 2=0
5c= - 2
c= -2/5
Therefore, the values of a, b, and c are -5/8, -4/7 and -2/5
Jessica:
2 minutes = 60 jumping jacks
1 minute = 30 jumping jacks
Dale:
5 minutes = 150 jumping jacks
1 minute = 30 jumping jacks
Ans: Yes, both their rates are the same. They both jump at 30/min.
Answer: 2 times 6 is 12 4 times 3 is 12 so its 6
540 assignments? Since there are 180 days in the school and you get three assignments each day you'd multiply 180 and 3 to get 540. Hope this helps!
