Answer: 81
Step-by-step explanation:
6.75 + 3 + 3.75 = X
X x 6 = 81
(1,4)
(4,1)
(2,3)
(3,2)
so there are 4 different combinations that equal 5
6 x 6 = 36 total possible outcomes of the dice
so they have a 4/36 reduces to 1/9 probability of equaling 5
Answer:
y=-x+2
Step-by-step explanation:
its asking y=mx+b
m slope (rise/run) --> rises up 2 for every time it moves over -2 times
so slope is -1
b= y intercept = 2
For this case we have the following data:
700 rabbits that represent 500% of the population of last year. So, to obtain the rabbit population of last year, we developed a rule of three:
700 -----------> 500%
x ---------------> 100%
Where x represents the rabbit population of last year.
Clearing x we have:

rabbits
In this way, last year there was a population of 140 rabbits.
Answer:
140 rabbits
By definition, the circumference of a circle is:

The area of a circle is:

Where,
r: radius of the circle.
When the radius is double, then the new area is:

Rewriting we have:

In terms of a we have:
Answer:
The new area of the circle in terms of a is:
