8 0

In 1884, a bacteriologist named Christian Gram created a test that could determine if a bacterium had a thick, mesh-like membrane called peptidoglycan. Bacteria with thick peptidoglycan are called gram positive. If the peptidoglycan layer is thin, it's classified as gram negative.

Contributing factors that lead to Xenophobia
Furkat [3]
Sorry its a very long answer-
1.) Failure to maintain the rule of law
The government's repeated failures to bring levels of violent crime under control contributed to an environment which saw people resort to violence without fear of arrest or successful prosecution.
2.) Border control

3.) Corruption

4.) Employment

5.) Education
This has been government's biggest failure and carries much of the blame for the high unemployment levels. It is arguable whether current state education is in its totality any better than that under apartheid. Only 1% of black matriculants achieve a good HG maths pass.
The education system is a good example where policy failures in one area compounded those in another.
6.) Slowing economic growth
7.) Foreign policy

8.) Service delivery

9.) Race relations

Tanya is training a turtle for a turtle race. For every 1/6 of an hour that the turtle is crawling he can travel 1/24 of a mile.
frozen [14]

The rate at which Tanya's turtle travels is 0.25mi/hr

This question is from a topic in mathematics called Rate.

<h3>Rate</h3>

This is a ratio in which different terms in different units are compared against each other.

In this question, for every 1/6 of an hour, the turtle is crawling 1/24 of mile.

Data given;

  • 1/24 miles in 1/6 hour

Let's express this mathematically

1/24 mi = 1/6 hr\\x mi = 1 hr\\x = (\frac{1}{24})/(\frac{1}{6})\\x = 0.25mi

What this calculation shows is that the turtle travels at 0.25mi/hr

The rate at which the turtle travels is 0.25 miles in an hour or 0.25mi/hr
