Okay. 3/4 of a cup of maple syrup is filled in 1/2 an hour. We can divide fractions to find the rate that the tree runs out syrup. To divide fractions, keep the first fraction the same, change multiplication into division, and flip the second fraction over. It would look like this: 3/4 * 2/1. 3/4 * 2/1 is 6/4 or 1 1/2 in mixed number form. Syrup flows from the tree at 1 1/2 cups per hour.
1) a^2 = c^2 - b^2
a^2 = 5^2 - 4^2
a^ 2 = 9
(Square root 9)
a = 3
2) a^ 2 + b^2 = c^2
8^2 + 4^2 = c^2
80 = c^2
(Square root of 80)
C = 8.9 cm
3) a^2 + b^2 = c^2
6^2 + 2^2 = c^2
40 = c^2
(Square root of 40)
C = 6.3 cm
4) a^2 + b^2 = c^2
10^2 + 24^2 = c^2
676 = c^2
(Square root of 676)
C = 26
5) a^2 + b^2 = c^2
6^2 + 5^2 = c^2
61 = c^2
C = 7.8cm
6) a^2 + b^2 = c^2
12^2 + 12^2 = c^2
288 = c^2
C = 16.97cm
7) 8^2 + 6^2 = c^2
100 = c^2
C = 10
8) a^2 = c^2 - b^2
a^2 = 25^2 - 20^2
a^2 = 225
a = 15
9) a^2 = 14^2 - 9^2
a^2 = 115
a = 10.7cm
10) a^2 = 20^2 - 15^2
a^2 = 175
a = 13.2cm
11) Does 15^2 + 8^2 = 17^2?
289 = 289
Yes it’s a right angled triangle because 15^2 + 8^2 = 17^2
Do the same for the others
12) 7^2 + 5^2 = 74
9^2 = 81
So it’s not a right angled triangle
13) 5^2 + 12^2 = 169
13^2 = 169
It is a right angled triangle
14) 9^2 + 12^2 = 225
16^2 = 256
Not a right angled triangle
15) 10^2 + 24^2 = 676
26^2 = 676
It is a right angled triangle
16) 2^2 + 2^2 = 8
3^2 = 9
Not a right angled triangle
