A gannet flies 24 1/2ft above sea level. It increases its elevation by 5ft. Then it dives and changes its elevation by -47 2/3ft. After it dives, what is the gannets elevation relative to sea level?

Answers

Answer:

Its elevation relative to the sea level is -18 1/6 ft (it is 18 1/6 below sea level)

Step-by-step explanation:

Here, we want to calculate the elevation relative to sea level

The sea level refer to the base of the sea

We follow the flight procedure;

distance of 24 1/2 ft above sea level , then go further up by 5

its elevation now is 24 1/2 + 5 = 29 1/2 ft

A change of -47 2/3 ft

So the elevation now will be;

29 1/2 - 47 2/3

= 59/2 - 143/3

= (177-286)/6 = -109/6

= -18 1/6 ft

The price of a television is $245. The sales tax rate is 8%. What is the amount of sales tax?

Answers

Answer:

$19.60

Step-by-step explanation:

245 is 100% of the total.

x is 108% of the total.

245/100 = x/108

245(108) = 26460

26460/100 = 264.6

264.6 - 245 = 19.6

The algebraic expression -5x+6y-3/x is not a polynomial.

The given polynomials are 7-z, 2p³q²-pq³ and -5x+6y-3/x.

What is the polynomial?

A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.

Here,

In 7-z has non-negative integer as exponent

So, it is a polynomial

In 2p³q²-pq³ has non-negative integer as exponent

So, it is a polynomial

In -5x+6y-3/x has negative integer as exponent, which is [tex]x^{-1}[/tex]

So, it is not a polynomial

Hence, the algebraic expression -5x+6y-3/x is not a polynomial.
