What is it that I am supposed to be doing?
To find percent tax, add the cost of the meal, which would be 11.20. A 5% tax would be 11.20*0.05=$0.56. This would be added on to the bill. So 11.20+0.56. This means the total cost of the meal is $11.76
Answer:
15
Step-by-step explanation:
Let Rama's current age be x.
Rama's Age 4 years ago = x - 4
3/5 of Rama's Age = 3/5 x
Difference = 0
(x - 4) - 3/5 x = 0
2/5 x = 4
x = 10
Rama's Age after 5 years = 10 + 5
= 15
Rama's Age After 5 Years is <u>1</u><u>5</u>
Answer: There will 486 bacteria in 31 hours.
Step-by-step explanation:
The population decay in bacteria is exponential.
Exponential function :
, where A = initial population, b multiplication decay factor, t= time:
As per given:
Initial population: 
After 36 hours, population = 
Divide both sides by 120,000 we get

Taking natural log on both sides , we get

At x= 31,

Hence, there will 486 bacteria in 31 hours.
The question gives us that cot ∅ = 1.5, and we need to find tan ∅ (∅ being theta). So, cotangent, which is <em>cot</em>, is equal to adjacent over opposite, and tangent, abbreviated <em>tan</em>, is equal to opposite over adjacent. Basically, we need to take the inverse of the given value for <em>cot</em><em>. </em>Doing so gives us 1/1.5, which is approximately 0.667. Therefore, the answer to your query is A. Hope this helps and have a great day!
