Answer:
It would be 8
Step-by-step explanation:
20% of 40 is 8
x + y = 24 where x and y are the 2 parts of diagonal Other diagonal wil be smaller that 24.
x^2 + z^2 = 13^2
y^2 + z^2 = 20^2 where z = 0.5 * length of smaller diagonal)
form last 2 equations
y^2 - x^2 = 20^2 - 13^2 = 231
now y = 24-x so we have
(24 - x)^2 - x^2 = 231
576 - 48x = 231
48x = 345
x = 7.1875
z^2 = 13^2 - 7.1875^2 = 117.34
z = 1.83
so smaller diagonal = 21.66 cm
looks like its the third choice.
SOLUTION
The total number of females =
if 14 have an A in the class, the number of students without A is:
8 male students do not have an A, therefore the number of female students without an A is:
The probability that a student does not have an A given that the student is female can be calculated thus:
We can conclude that the equation 36x + 9 equals -1/4.

What exactly is an equation?</h3>
- An equation, in its most basic form, is a mathematical statement demonstrating that two mathematical expressions are equal.
- 3x + 5 = 14, for example, is an equation in which the expressions 3x + 5 and 14 are separated by a 'equal' sign.
So,
- 36x + 9
- 36x + 9 = 0
- 36x = -9
- x = -9/36
- x = -1/4
Therefore, we can conclude that the equation 36x + 9 equals -1/4.

Divide 16 by the percentage:
16 / 0.35 = 45.71428571
16 is 35% of 45.71428571 inches. (round the answer as needed.)
