Answer:
is not polynomial.
Step-by-step explanation:
We have been given an expression . We are asked to determine whether the given expression is polynomial or not.
We know that a polynomial expression is in form , where n is a non-negative number and a is a constant.
Upon looking at our given expression, we can see that it has a negative exponent.
Since exponents in polynomials must be positive, therefore, our given expression is not a polynomial.
Answer:
Megan is not correct
Step-by-step explanation:
Since it takes 20 minutes to cook per kg, a total of 5.4kg will take 20 * 5.4 minutes to cook = 108 minutes to cook
Now, to cook for another 90 minutes. Time now is thus 90 + 108 = 198 minutes
Again, she is to leave for 30 minutes
So therefore, total time spent in cooking the chicken = 198 minutes + 30 minutes = 228 minutes
So the difference in time between 2:30 pm and 6pm is 3 hrs : 30 minutes
There are 60 minutes in an hour , so total amount of minutes is 3(60) + 30 = 180 + 30 = 210 minutes
What we calculated in minutes is more than what Megan says the cooking will take. So Megan isn’t correct
Answer:
a = 5
Step-by-step explanation:
Using Pythagoras' theorem in the right triangle
a² + 12² = 13²
a² + 144 = 169 ( subtract 144 from both sides )
a² = 25 ( take the square root of both sides )
a = = 5
Answer: 8
