Answer: 31
How: If there are two negative signs like this, you would connect them together and make it into a addition sign where you then can add them.
Answer:
Step-by-step explanation:
We are given a circle with a partially shaded region. First, we need to determine the area of the whole circle. To do this, we need the measurement of the radius of the circle:
Use the Pythagorean theorem to solve for the other leg of the right triangle inside the circle:
5^2 = 3^2 + x^2
x = 4
The radius is 4 + 1 cm = 5 cm
So the area of the circle is A = pi*r^2
A = 3.14 * (5)^2
A = 25pi cm^2
To solve for the area of the shaded region:
Ashaded = Acircle - Atriangles
we need to solve for the area of the triangles:
A = 1/2 *b*h
A = 1/2 *6 * 5
A = 15 cm^2
Atriangles = 2 * 15
Atriangles = 30 cm^2
Ashaded = 25pi - 30

Answer:
Constant of proportionality = 24
Equation: 
Step-by-step explanation:
Given:
'x' and 'y' are proportional to each other.
At 
Now, for a proportional relationship, the constant of proportionality is given as the ratio of the two values of the two variables that are in proportion.
Here, 'x' and 'y' are in proportion. So, the constant of proportionality is given as:
Therefore, the constant of proportionality is 24.
Now, a proportional relationship in 'x' and 'y' is given as:
Now, plug in the given value of 'k' and complete the equation. This gives,
Therefore, the equation that relates 'x' and 'y' is
