Hello! To draw a triangle, first, we have to follow a condition of existence.
This rule is:
• one of the sides must be ,bigger, ,than the absolute value, of the ,difference between the other two, sides
• the unknown side must be ,smaller ,than the ,sum of the other, two sides.
Let's write these rules using a, b, and c for the sides:
Considering a = 7.8 and b = 5.6:
[tex]\begin{gathered} |a-b|So, the
third side must be
smaller than 13.4 and bigger than 2.2.
If the diameter of the garden is 12 ft, then the radius is 6 ft.
The area is then π(6 ft)^2, or 36 ft^2.
Then the area of one of the 8 equal sections of the garden is 36/8 ft^2, or 9/2 ft^2, or 4.5 ft^2.
Answer: 525 cycles per second.
Step-by-step explanation:
The equation for inverse variation between x and y is given by :-
(1)
Given : The length of a violin string varies inversely with the frequency of its vibrations.
A violin string 14 inches long vibrates at a frequency of 450 cycles per second.
Let x = length of a violin
y= frequency of its vibrations
To find: The frequency of a 12 inch violin string.
Put 
in equation (1) , we get
Divide both sides by 12 , we get
Hence, the frequency of a 12 inch violin string = 525 cycles per second.
Answer:

Step-by-step explanation:
Answer:
1/27 in ^3
Step-by-step explanation:
where length - 1/3 inches
width - 1/3 inches
height - 1/3 inches
the formula to find volume is as follows
volume =
numerators should be multiplied by numerators and denominators by denominators
volume =
volume of the cube is 1/27 in.³
