Taking the difference of the both you can see that 2 kg of gummy bears would cost $18. So each kg of gummy bear is $9. Now subtract $9 from what Erika bought, and 3 kg of red hots are $12. So each kg of red hots are $4.
Answer:
b
Step-by-step explanation:
4800-1400 because 200*7 equals 1400.
Answer:
Step-by-step explanation:
Let one angle = A
Let the other angle = B
A + B = 180
A = B - 16.4 Substitute for A in the top equation
B - 16.4 + B = 180 Combine the left
2B - 16.4 = 180 Add 16.4 to both sides
2B = 180 + 16.4
2B = 196.4 Divide by 2
B = 196.4/2
B = 98.2
A = B - 16.4
A = 98.2 - 16.4
A = 81.8
Undefined is the answer because there is no value for x
Answer:
The year is 2020.
Step-by-step explanation:
Let the number of years passed since 2010 to reach population more than 7000000 be 'x'.
Given:
Initial population is, 
Growth rate is, 
Final population is, 
A population growth is an exponential growth and is modeled by the following function:
Taking log on both sides, we get:
Plug in all the given values and solve for 'x'.
So, for 
, the population is over 700,000. Therefore, from the tenth year after 2010, the population will be over 700,000.
Therefore, the tenth year after 2010 is 2020.
