Answer:
3 1/8
Step-by-step explanation:
You can rewrite 1 1/4 as 1 2/8, so adding them you'd get 2 9/8, or 3 1/8
Answer:
0.167
Step-by-step explanation:
It is actually 0.16666666... but you round the last six to a seven.
Establish two right triangles, both with the height of the pole, h.
Call x the distance from the pole to one stake. Then the distance from the other stake to the pole is 6 -x.
Apply Pytagora's equation to both triangles.
1) h^2 = 7^2 - x^2
2) h^2 = 8^2 - (6-x)^2
Eaual 1 to 2
7^2 - x^2 = 8^2 - 6^2 +12x -x^2
12x = 7^2 -8^2 +6^2 = 49 -64 + 36 = 21
x = 1.75
Substitue x-value in 1
h^2 = 49 - (1.75)^2 = 45.94
h = sqrt(45.94) = 6.78
Answer: option d.
