Dave buys a baseball for $15 plus an 8% tax. Mel buys a football for $20 plus an 8$ tax. How much did each person pay?

Answers

Answer 1

Answer: dave pays $15 and tax is $1.2 so dave spent a total of $16.20.

Mel pays $20 and tax is $1.6 so Mel spent a total of $21.60.

All you need to do is convert the percent to a decimal, so take 8 and divide by 100 and you get 0.08. then you need to multiply the cost by the tax so 15*0.08=1.2 then you just add tax to original amount 15+1.2=16.2

Answer:

Fraction of cloth that turns green = $(3)/(40)$

Step-by-step explanation:

Let total cloth be of length = 1 unit

Given $(5)/(8)$ of it is dipped in blue dye.

Fraction which is not dipped in blue is given as:

⇒ $1-(5)/(8)$

Taking LCD to subtract fractions.

⇒ $(8)/(8)-(5)/(8)$

⇒ $(3)/(8)$

She dips $(9)/(20)$ in yellow.

Comparing the fraction dipped in yellow which is $(9)/(20)$ and fraction which is not dipped in blue i.e. $(3)/(8)$

$(9)/(20),(3)/(8)$

Taking LCD between 8 and 20 = 40

We have:

$(9* 2)/(20* 2),(3* 5)/(8* 5)$

$(18)/(40),(15)/(40)$

Thus, we can say $(9)/(20)>(3)/(8)$

Since $(9)/(20)>(3)/(8)$ , so the part dipped in yellow will also cover some part which is blue.

Thus, fraction dipped in yellow and blue which turns green will be given as:

⇒ $(9)/(20)-(3)/(8)$

Subtracting by taking LCD =40.

⇒ $(9* 2)/(20* 2)-(3* 5)/(8* 5)$

⇒ $(18)/(40)-(15)/(40)$

⇒ $(3)/(40)$ (Answer)

The remainder obtained when x^4 + 3x^2 - 2x + 2 is divided by (x + b) is the square of the
remainder obtained when x^2 – 3 is divided by (x + b). Find the values of b.

Answers

Use the polynomial remainder theorem: the remainder upon dividing a polynomial $p(x)$ by $x-c$ is $p(c)$ .

$(-b)^4+3(-b)^2-2(-b)+2=b^4+3b^2+2b+2$

$((-b)^2-3)^2=b^4-6b^2+9$

Now

$b^4+3b^2+2b+2=b^4-6b^2+9\implies9b^2+2b-7=0$

$\implies(9b-7)(b+1)=0$

$\implies b=\frac79\text{ or }b=-1$

Substitute -2 into negative 2Y minus 8X equals six

Answers

When the value of x = -2 then, the value of y is 5.

When the value of y = -2 then the value of x is -0.25

Explanation:

Given:

-2y - 8x = 6

Considering x = -2

Then, we have to substitute the value of x = -2 in the equation.

-2y - 8(-2) = 6

-2y + 16 = 6

10 = 2y

y = 5

So, when the value of x = -2 then, the value of y is 5.

Considering y = -2

Then, we have to substitute the value of y = -2 in the equation.

-2 (-2) - 8x = 6

4 - 8x = 6

-2 = 8x

x = -0.25

So, when the value of y = -2 then the value of x is -0.25
