as +1 is added, the end number is increased by +1 as well?
Answer:
I collect 1 rock and 24 fossils
Friend collects 3 rocks and 12 fossils
Step-by-step explanation:
Let the rock be X and Fossils be Y
Friends collect 3 times rock= 3X and half as many fossils=y/2
Total object i collect= 25
Total object friend collect= 15
Using simultaneous equation
X+Y= 25 eqn 1
3X + Y/2= 15 equation 2
Using substitution method
X=25-Y from eqn 1
Substitute for X in eqn 2
3(25-y) + Y/2=15
75-3y+y/2=15
find the LCM and solve
150-6y+y=30
150-5y=30
collect like terms
-5y=30-150
-5y=-120
Y=24
Find the value of x using eqn 1 by substituting for the value of the gotten Y
X + Y= 25
X + 24= 25
X= 25-24
X=1
Since X stand for rock and Y stand for Fossils, we slot the values into the equation
I collect 1 rock and 24 fossils
While my friend collect 3 rock and 12 fossils
Answer:
-2 , -2 , 0 , 1 , 2 , 4 , 7 , 8 , 9 , 12
Step-by-step explanation:
Order each number from least to greatest. Note that if the number is numerically larger and attached is a negative sign (-), then it is towards the least. If it does not have a negative sign, it leans towards the most.
Your answer:
-2 , -2 , 0 , 1 , 2 , 4 , 7 , 8 , 9 , 12

The answer is C. 950.02 in^2
Answer:
![P_t\approx 244 \ bees](https://tex.z-dn.net/?f=P_t%5Capprox%20244%20%5C%20bees)
Step-by-step explanation:
-The bee's population follows an exponential decay of the form:
![P_t=P_oe^{-rt}](https://tex.z-dn.net/?f=P_t%3DP_oe%5E%7B-rt%7D)
is the population at time t
is the initial population size
is time and rate of decay respectively.
#We substitute and solve
:
![t=6/2=3\\\\\therefore P_t=P_oe^{-rt}\\\\=700e^{-0.35\times 3}\\\\\\=244.96\\\\\approx 244\ bees](https://tex.z-dn.net/?f=t%3D6%2F2%3D3%5C%5C%5C%5C%5Ctherefore%20P_t%3DP_oe%5E%7B-rt%7D%5C%5C%5C%5C%3D700e%5E%7B-0.35%5Ctimes%203%7D%5C%5C%5C%5C%5C%5C%3D244.96%5C%5C%5C%5C%5Capprox%20244%5C%20bees)
-Since it's a decay, we round down any fractional amount in the population.
Hence, the population after 6 months is approximately 244 bees
