The cost should be the same on day 3
Answer:
All 3 are right triangles.
Step-by-step explanation:
In a right triangle c^2 = a^2 + b^2 where c is the longest side. ( by Pythagoras).
a) 3^2 = 9, 6^2 = 36 and √27 ^ 2 = 27
36 = 9 + 27
So this is a right triangle.
b)
17^2 = 289, 15^2 = 225 and 8^2 = 64
289 = 225 + 64
Also right triangle.
c) √50 ^ 2 = 50, 5^2 = 25 and 5^2 = 25
So also right triangle.
Answer:
f = 48/5
Step-by-step explanation:
5f = 12 * 4
5f = 48
f = 48/5
Answer:
-3 1/2 + ( -6 1/2) = -10
5/8 - {-2/8} = 7/8
- 9/10 - 2/5 = -4
6 3/5 - (-2 1/5) = 44/5
Step-by-step explanation:
-3 1/2 + ( -6 1/2) = <em>-7/2 + (-13/2) = -20/2 =</em><em><u> </u></em><em><u>-10</u></em>
5/8 - {-2/8} = <em>5/8 + 2/8 = </em><u><em>7/8</em></u>
- 9/10 - 2/5 = <em>-18-2/5 = -20/5 = </em><u><em>-4</em></u>
6 3/5 - (-2 1/5) = <em>33/5 + 11/5 = </em><em><u>44/5</u></em>
