Oh, well that is just weird because the sixth student could be below average, average, or above average so there really is no way to tell. At least not from what I know now.

What is the error in this problem
castortr0y [4]

Answer:

12). LM = 37.1 units

13). c = 4.6 mi

Step-by-step explanation:

12). LM² = 23² + 20² - 2(23)(20)cos(119)°

    LM² = 529 + 400 - 920cos(119)°

    LM² = 929 - 920cos(119)°

    LM = \sqrt{929+446.03}

          = \sqrt{1375.03}

          = 37.08

          ≈ 37.1 units

13). c² = 5.4² + 3.6² - 2(5.4)(3.6)cos(58)°

    c² = 29.16 + 12.96 - 38.88cos(58)°

    c² = 42.12 - 38.88cos(58)°

    c = \sqrt{42.12-20.603}

    c = \sqrt{21.517}

    c = 4.6386

    c ≈ 4.6 mi

Find the value of k given that logk - log (k-2) = log5
victus00 [196]

k = \frac{5}{2}

using the ' laws of logarithms '

log x - log y = log ( \frac{x}{y})

logx = logy ↔ x = y

logk - log(k - 2) = log5

log ( \frac{k}{(k - 2)} =log 5

\frac{k}{(k - 2)} = 5

5(k - 2) = k

5k - 10 = k

4k = 10 ⇒ k = \frac{10}{4} = \frac{5}{2}

Use the variable x for the​ unknown, and write an equation representing the verbal sentence. Then solve the problem. The sum of
Minchanka [31]

Answer:

  • x+5 = -28
  • x = -33

Step-by-step explanation:

The translation to a math expression is ...

  <em>The sum of a number and 5 is negative 28.</em>

                          x     +      5      =    -28

Subtract 5 from both sides of the equation:

  x + 5 - 5 = -28 -5

  x = -33

The number is negative 33.
