Answer:

$\frac{1}{8}$

Step-by-step explanation:

To divide the 2 fractions

leave the first, change division to multiplication and turn the second upside down, that is

$\frac{2}{20}$ × $\frac{10}{8}$ ( cancel 2 and 8 by 2 and 10 and 20 by 10 )

= $\frac{1}{2}$ × $\frac{1}{4}$ ( multiply numerators and denominators )

= $\frac{1}{8}$

Answer:

19 minutes

Step-by-step explanation:

cost = .45+.36m

If we take 6.93 minus .45 for the minute, we get 6.48. We take 6.48 and divide it by .36 for each additional minute, which is 18. We take the 18 and add one more minute to it since .45 was covered for the first minute.

The product of algebraic expression is $\rm 2d^3 - 7d^2- 103d + 36$ .

We have to determine

What is the product of d - 9 and 2d^2+11d-4?

<h3>How to find the product of two algebraic expressions?</h3>

The product of the algebraic expressions is also an algebraic expression. Lastly, simplify the algebraic expression by the fundamental operations of terms for combining the like terms.

Therefore,

The product of algebraic expression is;

$\rm = (d - 9) \times (2d^2 + 11d - 4)\\\\= d (2d^2 + 11d - 4)-9 (2d^2 + 11d - 4)\\\\= 2d^3+11d^2-4d-18d^2-99d+36\\\\=2d^3 - 7d^2- 103d + 36$

Hence, the product of algebraic expression is $\rm 2d^3 - 7d^2- 103d + 36$ .
