Answer:
153.1ml
Step-by-step explanation:
We have 12.5ml of acid in the solution.
If we want this to be 3% then we can divide this value by 3 and times by 100 to get the total value.
416.6ml total solution amount
415.6-12.5-250=153.1
Answer:
$43
Step-by-step explanation:
88+29=117
117-74=43
You Spent $43 For The Concert.
<h3>#29</h3>
<u>Find the value of x:</u>
- 7x - 2 = 55 + 4x (as corresponding angles)
- 7x - 4x = 55 + 3
- 3x = 57
- x = 19
<u>Find the value of y:</u>
- y = 7x - 2 (as alternate exterior angles)
- y = 7*19 - 2
- y = 131
<h3>#30</h3>
<u>Find the value of x:</u>
- 14x - 34 = 9x + 1 (as alternate interior angles)
- 14x - 9x = 1 + 34
- 5x = 35
- x = 7
<u>Find the value of y:</u>
- y + (9x + 1) = 90 (as complementary angles)
- y = 90 - 9*7 - 1
- y = 26
You refer to a rectangular distribution.
I.e. Area ∝ probability
so, length x height = area
=> 6 x height = 1
so, height = 1/6
Therefore, greater than 2.25 minutes => 8-2.25 = 5.75 minutes
=> 5.75 x 1/6 = 0.9583
Since this is uniformly distributed, there is no need to
find the height or standard deviation.
