Let g be the number of grandchildren, and d be the number of dogs. They both have only one head, so the number of heads is

Grandchildren have 2 legs, while dogs have 4. So, the total number of legs is

From the first equation (the one for the heads) we can derive

Substitute this into the second to get

So, there are 9 dogs and (from the first equation

31.62
You use pythagorean theorem so 30 is legA and 10 is legB so 20^2+10^2= square root legC which is 31.62
Wouldn’t it be 0 cause 3-3 is 0 and 0 times anything is 0
By definition we have to:
A mathematical function is a relationship that is established between two sets, through which each element of the first set is assigned a single element of the second set or none.
The initial set or starting set is also called the domain; the final set or set of arrival, meanwhile, can be called codomain.
For this case, the table represents a function and the function is linear because the rate of change (slope) is constant and equal to 200.
Answer:
option D
Answer:
the bottom one 42.061
upper one 49/2pi = 76.969
Step-by-step explanation:
the bottom one
14^2 - 49pi = 42.061
upper one, put the shaded parts together and that forms a semicircle
49/2pi = 76.969
