PLEASE HELp tHHIS IS dUE IN AN HOUR!!!!! ITS MY LAST QuESTION Tony and Tiffany colleg\ct semi-precious stones. At the Rockhound
DIA [1.3K]

Answer:

Tiffany purchase the better buy.

Step-by-step explanation:

given data

Tiffany paid  = $38

snowflake obsidian = 9 pounds

Tony paid = $19

same type of stone = 3 pounds

solution

Tiffany shopped well in this scenario. Mainly because Tiffany paid less per pound than Tony. This can be calculated by dividing the total amount paid by the amount received by each

so for Tiffany

= $38 ÷ 9

= $4.22 per pound

and for Tony  

=$19 ÷ 3

= $6.33 per pound

so that here Tiffany paid $4.22 per pound and Tony paid $6.33 per pound

so here whole $2.11 more than Tiffany

so that with this Tiffany purchase the better buy.

Consider the function represented by the equation 6q = 3s - 9. Write the equation in function notation, where q is the independe
Llana [10]
Q = 3s - 9/6
q = 3(s - 3)/6
q = s - 3/2

6q + 9 = 3s
6q + 9/3 = s
3(2q + 3)/3 = s
2q + 3 = s
s = 2q + 3

Total Price: The sales tax rate is 5%. If the sales tax on a 10-speed bicycle is $9, what is the purchase price?
Lesechka [4]

Answer:

The purchase price is $180

The total price is: $189

Step-by-step explanation:

Sales tax rate = 5\%

Sales tax on bike = $9

We need to find the purchase price.

Let purchase price = x

We know that Sales tax = 5% of x

and Total price = Purchase Price + Sales tax

So, we can write:

Sales tax = 5% of x

Putting values and finding x

9 =5\% \:of\: x\\9=\frac{5}{100}\:of\:x \\x= \frac{9*100}{5}\\x=180

So, the value of x i.e Purchase price = $180

The purchase price is $180

Now finding the total price of bicycle

Total price = Purchase Price + Sales tax

Total price = 180 + 9

Total price = $189

So, The total price is: $189

Which expressions are polynomials?
cupoosta [38]

<em><u>The expressions that are polynomial are:</u></em>

6 + w

2x^4 - y

z + 1

<em><u>Solution:</u></em>

A polynomial is an expression with variables and coefficients with the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables

1) 6 + w

Here "w" is a variable, hence it is a polynomial expression

2)\ 2x^4 - y

This is a polynomial, since it has variables and coefficients and variable with non negative exponent

3) z + 1

This is also a polynomial with variable "z" and has addition operation

4)\ y^2 - y\sqrt{3} + 4

Since it has root so it is not a polynomial
