Maria had planned to walk 10 1/8 miles on wednesday, if she walked 7 2/8 miles in the morning how far would she need to walk in
Ugo [173]

Answer:

Distance Maria had to walk in the afternoon is 2\frac{7}{8}

Step-by-step explanation:

Lets take that Maria walked x miles in the afternoon.

Distance walked in the morning + distance walked in the afternoon = 10\frac{1}{8}

⇒7\frac{2}{8} +x=10\frac{1}{8}

\frac{58}{8} +\frac{8x}{8} =\frac{81}{8}

\frac{58+8x}{8} =\frac{81}{8}

58+8x=81

8x=81-58\\

8x=23

x=\frac{23}{8}

x=2\frac{7}{8}

Determine the common ratio and find the next three terms of the geometric sequence t8, t5, t2
attashe74 [19]
The common ratio of the given geometric sequence is the number that is multiplied to the first term in order to get the second term. Consequently, this is also the number multiplied to the second term to get the third term. This cycle goes on and on until a certain term is acquired. In this item, the common ratio r is,

    r = t⁵/t⁸ = t²/t⁵

The answer, r = t⁻³.

The next three terms are,

    n₄ = (t²)(t⁻³) = t⁻¹
    n₅ = (t⁻¹)(t⁻³) = t⁻⁴
    n₆ = (t⁻⁴)(t⁻³) = t⁻⁷

The answers for the next three terms are as reflected above as n₄, n₅, and n₆, respectively.

Factor the expressions .<br> 36 + 8z
Sophie [7]

Answer:

4 × ( 9 + 2z)

Step-by-step explanation:

36 + 8z = 4 × (9) + 4 × (2z) ; so here 4 is a common factor

            = 4 × ( 9 + 2z)  

we can also write it like this

36 + 8z = 2 × ( 18 + 4z)
