1) The length of the shadow the tree cast and the shadow Bill cast needs to be added together which makes 34 ft
2) After setting up Bill's Height and Shadow over each other 6ft/9ft.. Set that equal to another proportion...
3) The next proportion is x (the height of the tree) and the length (along the bottom) X/34
4 Solveeee :) 6/9 multiplied by 34 is 22.6- 22 ⅔ft as a fraction
andddd you're done that's the answer
Hope this helpppsss :)
X= -4 and y= 7 .............
I got 226.79. You could round the answer if necessary.
Answer:
Step-by-step explanation:
The approximate learning percentage can be estimated by using a doubling method.
If we breakdown the repetitions into three consecutive parts, we have:
1 - 2
2 - 4
3 - 6
then
1 - 2 → 46P = 39
P =39/46
P = 0.8478
P = 84.8%
2 - 4 → 39P = 33
P = 33/39
P = 0.84615
P = 84.6%
3 - 6 → 35P = 30
P = 30/35
P = 0.8571
P = 85.7%
The average value of P = (84.8 + 84.6 + 85.7)/3 = 85.03%
85%
From the tables of Learning Curves coefficient
The values are likened against times derived from 85% table factors at T
= 46
Unit 1 2 3 4 5 6
Date 46 39 35 33 32 30
Computed - 39.1 35.56 33.26 31.56 30.22
b. Using your answer from part a, estimate the average completion time per repetition assuming a total of 30 repetitions are planned. (Round your answer to 3 decimal places.)
The average completion time = 
At the total time factor 30, from the learning curves table , n(30) = 17.091
Thus:
The average completion time = 
The average completion time = 
The average completion time = 
Answer:
7
Step-by-step explanation:
+ 18 = 67
<u><em>You first need to subtract 18 from both sides:</em></u>
<u><em /></u> + 18 = 67
- 18 -18
_________
= 49
<u><em>To get rid of the square, you need to square root both sides:</em></u>
<u><em /></u> = 49
<u><em>This leaves you with:</em></u>
x = 7
