Rachel rode her bike for seven -quarters of a mile on Monday and nine-fifths of a mile on Tuesday. How many miles did she ride a
Romashka [77]

Answer:

3 11/20 miles

Step-by-step explanation:

Monday = seven -quarters of a mile

= 7/4 miles

Tuesday = nine-fifths of a mile

= 9/5 miles

How many miles did she ride altogether?

Total miles she rode altogether = Monday + Tuesday

= 7/4 + 9/5

= (35+36)/20

= 71/20

= 3 11/20

Total miles she rode altogether = 3 11/20 miles

Use pascal's triangle to expand the following binomial expression <br>1.(2k-1/3)⁶​
Gwar [14]

9514 1404 393

Answer:

  64k^6 -64k^5 +(80/3)k^4 -(160/27)k^3 +(20/27)k^2 -(4/81)k +1/729

Step-by-step explanation:

The row of Pascal's triangle we need for a 6th power expansion is ...

  1, 6, 15, 20, 15, 6, 1

These are the coefficients of the products (a^(n-k))(b^k) in the expansion of (a+b)^n as k ranges from 0 to n.

Your expansion is ...

  1(2k)^6(-1/3)^0 +6(2k)^5(-1/3)^1 +15(2k)^4(-1/3)^2 +20(2k)^3(-1/3)^3 +...

     15(2k)^2(-1/3)^4 +6(2k)^1(-1/3)^5 +1(2k)^0(-1/3)^6

  = 64k^6 -64k^5 +(80/3)k^4 -(160/27)k^3 +(20/27)k^2 -(4/81)k +1/729
