any more help just ask :)
Given that the problem does not specify if
y is <span>opposite, adjacent or hypotenuse side, I will provide two solutions to this problem.
Case 1. Y is the hypotenuse side. (See figure 1)
According to the Pythagorean Theorem, for a right triangle, it is true that:
</span>
<span>
being c the hypotenuse side and a and b the opposite and adjacent side respectively. So, for the figure 1 it is true that:
</span><span>
z = a = 15cm
x = b = 9cm
y = c = ?
</span>
∴
Case 2. Y is the opposite side (The same happens as if it were the adjacent side). (See figure 2)
From the equation:
For the figure:
y = a = ?
x = b = 9cm
z = c = 15cm
We need to isolate a, so:
∴
The one that is like this:^
Answer:
density = 0.7 gm/cm³
Explanation:
Density can be calculated using the following rule:
Density = mass / volume
We are given that:
mass = 2.75 grams
volume = 4 cm³
Substitute with the givens in the above equation to get the value of the density as follows:
density = 2.75 / 4
density = 0.6875 which is approximately 0.7 gm/cm³
Hope this helps :)
Answer:
150 : 200
Explanation:
3 + 4 = 7
350 / 7 = 50
50 x 3 = 150
50 x 4 = 200
