Answer:
Step-by-step explanation:
Area for triangle is equal to half base time perpendicular height.
note that it's 10cm X 12 cm that's how you get cm²
Answer:
C
Step-by-step explanation:
Florida is on the 30 mark so its 30 then Alaska is in between 10 and 20 half so half of these numbers is 15 then your going to subtract 30-15 leaving you with 15 and as you can see that answer is presented
<span> 110y+10=340
Subtract 10 from both sides
110y=330
Divide by 110 to get variable on its own
</span>110y/110=330/110
y=3
Complete Question
Bacteria culture A culture of the bacterium Rhodobacter sphaeroids initially had 30 bacteria and t hours later increases at a rate of 2e^2t 1 bacteria per hour. Find the population size after four hours
Answer:
3010
Step-by-step explanation:
We were given the rate: 2e^2t
Step 1
We would integrate
P = Population
dP/dt = 2e^2t
dP =( 2e^2t) dt
∫dP = ∫ 2e^2t dt
P(t) = (2e^2t)/2 + C
P(t) = e^2t + C
Step 2
We solve for C
The culture initially has 30 bacteria
When t = 0
P(0) = 30
P(0) = e^2t + C
30 = e^2× 0 + C
30 = 1 + C
C = 30 - 1
C = 29
Step 3
Find the population size after four hours
t = 4, C = 29
P(t) = e^2t + C
P(4) = e^2 × 4 + 29
P(4) = e^8 + 29
P(4) = 3009.957987
Approximately = 3010 bacteria
Answer:
2/7
Step-by-step explanation:
There are seven tiles. You want to 5 and the 6 so the fraction is 2/7. That's the chance that you have to pull both numbers.
