Answer: There are 8 snake and 3 elephants.
Step-by-step explanation:
Let x= Number of snakes
y= Number of elephants
We know that , snake has no legs elephant has 4 legs.
Then, Total animals = x+y=11 (i)
Total legs = 4y = 12
⇒ y=3 .. (ii)[divide both sides by 4]
Substitute value of y from (ii) in (i) , we get

Hence, there are 8 snake and 3 elephants.
The population of Ohio will be 10 million in the year 1970
The population growth of Ohio is represented by the function:

P is the population in millions
t is the number of years since 1900
To find the year that the population of Ohio will be 10 million, substitute P = 10 into the function P(t) and solve for t

t = 70 years (to the nearest whole number)
70 years after 1900 will be 1970
Therefore, the population of Ohio will be 10 million in the year 1970

Answer:
option A. 21 sec
Step-by-step explanation:
Speed = the distance over the time
Given:
Speed = 2 m/s and distance = 42 m and time = t
So,
2 = 42/t
Solve for t
t = 42/2 = 21 sec.
The answer is option A. 21 sec
Answer:
A= 4
B= 4
C= -1
D= 4
E= -1
F= 4
G= -1
Step-by-step explanation:
The expected value equation is the probability of something happening multiplied by the amount of times it happens. In this case you have four equal sized sections, so you have a one in four chance to land in any of these sections. A, B, D, and F represent the four for this one in four chance. C, E, and G represent the amount of points you get when you land on those sections, in this case -1
