A <em>number line</em> is a <u>system</u> that shows the location of all <em>directed numbers </em>on a <u>straight</u> <u>line</u>. All <em>numbers</em> can be plotted on a <em>number line</em>. Thus the required answer to the given question is; Option A. Point A is <em>twenty-two</em> <em>ninths</em>, point B is <em>square root</em> of 10, and point C is <em>square root</em> of 13.
A <u>line</u> on which the <em>locations</em> of all <em>directed number</em>s can be shown is termed a <u>number line</u>. It has <u>two</u> extreme ends ranging from -∞ to +∞. Note that all <em>numbers</em> can be plotted on a <em>number line</em>. So that the <u>position</u> of any given <em>number</em> can be shown on the <u>line</u>.
In the given question, we have:
i. square root of 10 =
= 3.2
ii. square root of 13 =
= 3.6
iii. twenty-two ninths =
= 2.4
But it has been given that;
Number line with points plotted at; <em>two</em> and <em>four-tenths</em> labeled point<u> A,</u> <em>three</em> and <em>two-tenths</em> labeled point <u>B</u>, and <em>three</em> and <em>six-tenths</em> labeled Point <u>C.</u>
Therefore,
Point A is <em>twenty-two ninths</em>, point B is <u>square</u> <u>root </u>of 10, and point C is <em>square root</em> of 13.
Thus the correct <u>option</u> is A.

Answer:
Step-by-step explanation:
This is one of the more interesting motion problems I've seen. I like it! If Kelly is driving north (straight up) for 9 miles, then turns east (right) and drives for 12 miles, what we have there are 2 sides of a right triangle. The hypotenuse is created by Brenda's trip, which originated from the same starting point as Kelly and went straight to the destination, no turns. We need the distance formula to solve this problem, so that means we need to find the distance that Brenda drove. Using Pythagorean's Theorem:
and
and
so
c = 15.
Brenda drove 15 miles. Now we can fill in a table with the info:
d = r x t
Kelly 12+9 42 t
Brenda 15 45 t
Because they both left at the same time, t represents that same time, whatever that time is. That's our unknown.
If d = rt, then for Kelly:
21 = 42t
For Brenda
15 = 45t
Solve Kelly's equation for t to get
t = 1/2 hr or 30 minutes
Solve Brenda's equations for t to get
t = 1/3 hr or 20 minutes
That means that Brenda arrived at the destination 10 minutes sooner than Kelly.
