i hope u can understand...

They both should get 1/2 of the rope, which is three. You can make a visual of one rope and one more rope divided into three boxes and color in one of the three boxes. Not sure if its right but hope it helps. :)

3a² . 2a³ find the product

Answers

Answer:

$6a^(5)$ .

Step-by-step explanation:

To multiply exponents, you will need to begin by multiplying the coefficients as normal. In this instance:

3 · 2 = 6.

When multiplying exponents, however, remember that you must ADD the exponents. Therefore:

3a² · 2a³ = $6a^(5)$

Final answer:

The product of 3a² and 2a³ is found by multiplying the coefficients (the numbers in front of 'a') and adding the exponents for 'a'. The result is 6a⁵.

Explanation:

To find the product of 3a² and 2a³, first you multiply the numerical coefficients and then you add the exponents of 'a'. The numerical coefficient for the first expression is 3 and for the second expression it's 2, multiplying these together we get 6. For the powers of 'a', since both 'a' terms in the two expressions are raised to powers (2 and 3), you add these powers together when multiplying, thus a² * a³ = a⁵. So the final answer is 6a⁵.

There are 480 jellybeans in an 8-ounce jar. How many jellybeans are there per ounce in the jar?0.017
6
60
3,840

Answers

For this case, what we must do is divide the total amount of jellybeans by the total number of ounces.

For this, we use the following equation:

$r = \frac {amount\ of\ jellybeans} {number\ of\ ounces}$

Substituting values:

$r = \frac {480} {8}\nr = 60$

Answer:

There are 60 jellybeans per ounce in the jar.

Option 3

The answer would be 60. This is because 480/8=60.

What are the leading coefficient and degree of the polynomial?
-7 -10w^7+12w +
15w^9

Answers

Rewritten:
15w^9 - 10w^7 + 12w - 7

Leading coefficient: 15

Degree of the polynomial: 9

Final answer:

The leading coefficient of the polynomial 15w9 - 10w7 + 12w -7 is 15 and the degree of the polynomial is 9.

Explanation:

The polynomial in question is -7 -10w7 + 12w + 15w9. To find the leading coefficient and degree of the polynomial, we need to reorder the terms from highest to lowest power of w. The proper order is 15w9 - 10w7 + 12w -7. In a polynomial, the leading coefficient is the coefficient of the term with the highest degree. So, the leading coefficient in this polynomial is 15. The degree of a polynomial is the highest power in the polynomial. Therefore, the degree of this polynomial is 9.
