Each marble bag sold by Melissa's Marble Company contains 3 orange marbles for every 5 blue marbles. If a bag has 24 orange marbles, how many blue marbles does it contain?

Answers

3/5=24/x. cross multiply, you get 120=3x. divide by 3, x = **40**

3:5

3 to 5

3
-----
5

First we will divide to see who many sets of orange there are in the bag.

24 ÷ 3 = 8

Since there are 8 sets of orange we will multiply8 by 5 since for every 3 orange marbles there are 5 blue marbles.

8 × 5 = 40

SO, a bag contains 24 orange marbles and 40 blue marbles.

The answer I get based off of the question is 1000.

find the zeros of the polynomial x square-3 and verify the reationship between the zeros and the coefficient.

Answers

Answer:

√3, and -√3

Step-by-step explanation:

to find the zeros or roots of the polinomial x²-3 make it equal to zero and solve for x

x²-3=0 add 3 to both sides to isolate x

x² = 3 squareroot both sides

√x²= √3

x= ±√3 are the two zeros

What is the quotient (2x4 – 3x3 – 3x2 + 7x – 3) ÷ (x2 – 2x + 1)?

Answers

Answer:

Quotient: $2x^2+x-3$

Please see the attachment.

Step-by-step explanation:

Given: $(2x^4-3x^3-3x^2+7x-3)/ (x^2-2x+1)$

We are given rational expression and need to find quotient.

Using long division method to find the quotient.

First we get rid of $2x^4$ by $x^2$

$x^2-2x+1$ ) $2x^4-3x^3-3x^2+7x-3$ ( $2x^2+x-3$

$-2x^4+4x^3-2x^2$

$x^3-5x^2+7x$

$-x^3+2x^2-x$

$-3x^2+6x-3$

$3x^2-6x+3$

$0$

Hence, The quotient of division is $2x^2+x-3$

Here you have two polynomials:

1. The dividend - $f(x)=2x^4 - 3x^3 - 3x^2 + 7x - 3$

2. The divisor - $g(x)=x^2 - 2x + 1$ .

Since divisor is perfect square $g(x)=x^2 - 2x + 1=(x-1)^2$ , you should check what is the quotient after division f(x) by (x-1):

$f(x)=2x^4 - 3x^3 - 3x^2 + 7x - 3=(x-1)(2x^3-x^2-4x+3)=(x-1)(x-1)(2x^2+x-3)=(x-1)^2(2x^2+x-3)=g(x)(2x^2+x-3).$

Then the quotient is $2x^2+x-3$ .

What is the lowest price per item?$6 for 3
$9 for 6
$10 for 8
$1.40 each

Answers

For each, it's easier to find what one item costs.

$6 for 3 = 6 divide by 3 = $2 per item
$9 for 6 = 9 divide by 6 = $1.50 per item
$10 for 8 = 10 divide by 8 = $1.25 per item
$1.40 per item

The best deal for lowest price per item is the $10 for 8

Answer:

$10 for 8.
