10+10=20 = length
20 + 18 = 38 width = 18 or 9 on each side
10 x 9 = 90
Answer 90
Physics: each of two or more atomic nuclei that have the same atomic number and the same mass number but different energy states.
chemistry: each of two or more compounds with the same formula but a different arrangement of atoms in the molecule and different properties.
Answer:
And rounded up we have that n=8068
Step-by-step explanation:
The margin of error for the proportion interval is given by this:
(a)
We want for this case a 95% of confidence desired, our significance level would be given by and . And the critical value would be given by:
The margin of error for this case is and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The estimated proportion for this case is . And replacing into equation (b) the values from part a we got:
And rounded up we have that n=8068
How many students would there be? did not see that information if that is the question but if not I say go with the bus that has more seats yes it is more expensive but more space is better!
Answer:
x = 6
Step-by-step explanation:
Given
6x² - 2x + 36 = 5x² + 10x ( subtract 5x² + 10x from both sides )
x² - 12x + 36 = 0 ← in standard form
This is a perfect square of the form
(x - a)² = x² - 2ax + a²
36 = 6² ⇒ a = 6 and 2ax = (2 × 6)x = 12x, hence
(x - 6)² = 0
x - 6 = 0 ⇒ x = 6
