Answer:

Step-by-step explanation:

Multiply by 10 on both sides,

so 
Number of pencils bough by the student = 84
Number of pencils sharpened by the student = 35
Then
The number of pencils that was not sharpened = (84 - 35)
= 49
So 35 pencils have been sharpened and 49 pencils have not been sharpened.
Then Number of pencils unsharpened:Number of pencils sharpened = 49:35
= 7:5
So the ratio of the number of unsharpened pencil to the number of sharpened pencil is 7:5
Answer:
x-√6
Step-by-step explanation:
Non-integer powers of the variable disqualifies the expression from being a polynomial. √x -6 has x to the 1/2 power, so that expression is not a polynomial. Polynomials may have any real or complex, rational or irrational coefficients. (We usually study only polynomials with real coefficients.)
x-√6 is a polynomial
Answer:
<h2>1986, 1996</h2>
Step-by-step explanation:
Given, Annual passenger revenue for the years 1980 to 2000 id=s modeled with the formula
.
Here,
is the annual revenue in millions of dollars,
is the number of years since January 1, 1980.
Revenue in a year was $ 790 million.
So, 
So, after 6 yrs and 16 yrs from January 1, 1980, the Passenger revenue equals $ 790 million.
∴ Passenger revenue equals $ 790 million in 1986 and 1996.
Polygon a figure especially closed figure having three or more sides usually straight side.
So the answer would be equilateral
