Tell whether the given value is a solution of the inequality. (yes or no) -2 ≤ k/3; k = -9

Mathematics
1 answer:
olga55 [171]2 years ago
4 0

Answer:  No, it is not a solution

Work Shown:

-2 ≤ k/3

-2 ≤ -9/3

-2 ≤ -3

The last inequality is false because -3 should be smaller than -2 (not the other way around). Use a number line to help see this.

Since the last inequality is false, the original inequality must also be false for that particular k value. Therefore, k = -9 is not a solution.

Answer:

  • 55°, 70°, 55°

Step-by-step explanation:

<u>Δ MHP is right triangle, therefore</u>

<u>ΔMNP  is isosceles triangle as MN = MP, therefore</u>

  • m∠N = m∠P = 55°
  • m∠NMP = 180° - 2*55° = 70°

4) Allison practices her violin for at least 12 hours per week. She practices for three fourths of an hour each
zaharov [31]

Answer:

12

Step-by-step explanation:

So, she practices 12 hrs per week, and already has practiced 3 hrs this week.

This means she has 9 hrs left to practice.

3/4 of an hour is one session, so to find out the number of sessions she needs, you have to do (9 hours)/(one session)

which is basically 9 / ( 3/4)

\frac{9}{3/4}=\frac{9}{1} / \frac{3}{4}  = \frac{9}{1} * \frac{4}{3} = \frac{36}{3}  = 12

She needs 12 more sessions.
