A new watch costs $120 at the store. If it goes on sale for 75% off and has a sales tax of 6%, what is the final cost of the watch?

Answer:

y²(y + 3)(5y - 3)

Step-by-step explanation:

Given

5[tex]y^{4}[/tex] + 12y³ - 9y² ← factor out y² from each term

= y²(5y² + 12y - 9) ← factor the quadratic

Consider the factors of the product of the y² term and the constant term which sum to give the coefficient of the y- term

product = 5 × - 9 = - 45 and sum = + 12

The factors are + 15 and - 3

Use these factors to split the y- term

5y² + 15y - 3y - 9 ( factor the first/second and third/fourth terms )

= 5y(y + 3) - 3(y + 3) ← factor out (y + 3) from each term

= (y + 3)(5y - 3), so

5y² + 12y - 9 = (y + 3)(5y - 3)

Then

5[tex]y^{4}[/tex] + 12y³ - 9y² = y²(y + 3)(5y - 3) ← in factored form

Step-by-step explanation:

His total pay on Wednesday and on Thursday is 516.75 dollars

Wages can be sum of amount of money collected after a service is rendered.

Given that Paul Aymes is a chrome plater at a local plant. If he plates 300 items or more, he is paid $1.25 each. For less than 300 items, he is paid $0.75 each. What is his total pay if he plates 321 items on Wednesday and 154 items on Thursday ?

For 300 item or more items on Wednesday: 321 x 1.25 = 401.25 dollars

For Less than 300 items on Thursday: 154 x 0.75 = 115.5 dollars

The total pay = 401.25 + 115.5 = 516.75 dollars

Therefore, his total pay on Wednesday and on Thursday is 516.75 dollars

Answer:

D. y=x+6

Step-by-step explanation:

To find out which one of these ordered pairs are solutions you just plug the three points into them.

For y=2x+5

(1,7)

7=2+5 which is 7=7 which is true

(3,9)

9=6+5 which is 9=11 which is not true so y=2x+5 is not an option

For y=4+3x

(1,7)

7=4+3 which is 7=7 which is true

(3,9)

9=4+9 which is 9=13 which is not true so y=4+3x is not an option

For y=5+2x

(1,7)

7=5+2 which is 7=7 which is true

(3,9)

9=5+6 which is 9=11 which is not true so y=5+2x is not an option

For y=x+6

(1,7)

7=1+6 which is 7=7 which is true

(3,9)

9=3+6 which is 9=9 which is true

(5,11)

11=5+6 which is 11=11 which is true so

D. y=x+6 is the answer

Answer:

2 lbs. for $4.50

Step-by-step explanation:

Do a ratio

2 : 4.50

You want to see how much it cost per pound, so divide them by 2

2 ÷ 2 : 4.50 ÷ 2

1 : 2.25

So per pound, the hamburger will cost $ 2.25

________________________________________________________

3 : 6.90

You want to see how much it cost per pound, so all you need to do is divide them by 3

3 ÷ 3 : 6.90 ÷ 3

1 : 2.3

So for the first one, it cost 2.25 per pound, and for the second one, it cost 2.3 per pound....the one that is better will be 2.25 because it cost 5 cents less than the second one

Answer:

A) Container X

Step-by-step explanation:

X=2C:6S  ratio, now reduce amount but keep the same ratio

X=1C:3S  

Y=4C:8S  ratio, now reduce amount but keep the same ratio

Y=1C:2S

Container X has the sweeter water because it's ratio of sugar to water is higher.

Container Y is the water sweeter.

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

Container X has 2 cups of water with 6 teaspoons of sugar.

And, Container Y has 4 cups of water with 8 teaspoons of sugar.

Now,

Since, Container X has 2 cups of water with 6 teaspoons of sugar.

Hence, The ratio of water with sugar for container X = 2 : 6

                                                                                 = 1 : 3

And, Container Y has 4 cups of water with 8 teaspoons of sugar.

Hence, The ratio of water with sugar for container Y = 4 : 8

                                                                                 = 1 : 2

Cleary, We get;

⇒ 1/3 < 1/2

So, Water in Container Y is more sweeter than X.
