Answer:
![-0.4t^2+130t+1200>9500](https://tex.z-dn.net/?f=-0.4t%5E2%2B130t%2B1200%3E9500)
Step-by-step explanation:
The given expression is
![p=-0.4t^2+130t+1200](https://tex.z-dn.net/?f=p%3D-0.4t%5E2%2B130t%2B1200)
where
= Population of rabbits
= Time in months
Now, the population is greater than ![9500](https://tex.z-dn.net/?f=9500)
So, the algebraic inequality that expresses the question "when is the population greater than 9500?" is
![-0.4t^2+130t+1200>9500](https://tex.z-dn.net/?f=-0.4t%5E2%2B130t%2B1200%3E9500)
52 minutes 30 seconds
Take 60 minutes divide it by 8 to figure out what 1/8 of an hour is.
Then multiply our answer by 7 to find out how many minutes are in 7/8 of an hour.
Answer:
3/7
Step-by-step explanation:
1/3 = 7/3
so you have 7/3 and 5/7
find the common denominator and
devide the new denominator by the old denominator
and then multiply that number by the numinator of each fraction
and you should get
49/21 and 15/21
then you multiply the 15/21 by 2 because the questions asks you to determine the amount of water left after 2 days
and you get 30/21
then do 49/21 - 30/21 and you should get 19/21
3 goes into 19 and 21 so you devide 19 and 21 by 3 and you get 3/7
Answer:
triangle =3
square= -2
star=7
circle=4
◇=18
right angled triangle= -5
Step-by-step explanation:
2triangle-1=5
+1 +1
2 triangles=6
1 triangle=3
3+ what is equal to one
the answer is -2
3-(2×-2)
3--4=7
second puzzle
3 circles =12
1 circle =4
◇+2=5 circles
◇+2=20
-2 -2
◇=18
2○=◇+ 2 right angle triangles
8= 18 + 2 right angled triangles
-10= 2 right angled triangles
-5= right angled triangle
For this case we have an equation of the form:
h (t) = - (1/2) * a * t ^ 2 + vo * t + h0
Where,
vo: initial speed
a: acceleration:
h0: initial height.
We have the following equation:
h (t) = - 16t2 + 19t + 110
Therefore, the initial velocity is:
vo = 19 feet / s
Answer:
The initial velocity when the rock is thrown:
vo = 19 feet / s
