The given statement is false.

Given, that the sum of two sides of a triangle is greater than or equal to the third side.

considering 2 cm, 3 cm, 4 cm

Let the two sides be 2 cm and 3 cm

Let the third side be 4 cm

Now, sum of two sides = 2 + 3 = 5 cm

So, 5 > 4

Therefore, the given statement is false.

A triangle's total internal angles are always equal to 180 degrees. This is referred to as the triangle's angle sum property. There are three sides and three angles in every triangle, some of which may be the same. Triangles are three-sided shapes. The various kinds of triangles go by various names. The size of the angles and the length of the sides determine the type of triangle (corners). Equilateral, isosceles, and scalene triangles are the three varieties of triangles based on the length of the sides.

The trucks arrive 10 minutes after the first call. The first and the second truck travel for 5 miles and 8 miles respectively.

In a time difference of 3 minutes, two fire trucks are called.

The average speed of the first truck is 30 miles per hour.

The average speed of the second truck is 60 miles per hour.

The trucks totally travel for 12 miles and arrive at the same time.

Let d be the number of miles the first truck drove.

Let t be the number of minutes it took the first truck to travel.

Now, Convert 30 miles per hour to a half mile per minute and 60 miles per hour to a mile per minute as we are measuring time in minutes.

For the first truck:

d = 0.5t

The second truck traveled 12 - d miles if the first truck traveled d miles. In the event where the first truck traveled for t minutes and was called 3 minutes later, the second vehicle would have gone for t - 3 minutes.

For the second truck:

12 - d = t - 3

Therefore,

12 - 0.5t = t - 3

15 = 1.5t

t = 15 / 1.5

t = 10 minutes

The trucks arrive after 10 minutes after the first call.

Then,

d = 0.5t = 0.5(10) = 5 miles

And 12 - d = 12 - 5 = 8 miles.

Hence, the first truck traveled for 5 miles and the second truck traveled for 8 miles.

The pool that Reggie drew will be 24 millimeters long, compare to real life which is 24 meters long.

As we can't create a real-life dimension in a small sheet of paper, we opted for a small scale that covers up the large length. As we are given, the scale of the drawing is 4 millimeters: 3 meters, which means 1 millimeter is equal to 3/4 meters, and the size of the pool in real life is 24 meters.

So, the length of the pool in the drawing is = 24*(3/4)

Meena would take 4 hours to drive 196 miles.

We will begin with calculation of number of miles Meena drives in 1 hour. We need to perform division as per the formula given below to find the speed. Then we will calculate the time required for driving 196 miles.

So, formula stating rate or speed of driving -

Speed = distance ÷ time

Keep the values in formula to find the speed

Speed = 245 ÷ 5

Performing division

Speed = 49 miles per hour

So, Meena drives 49 miles in 1 hour.

For driving 196 miles, the time required = (1 ÷ 49) × 196

Performing multiplication and division

Time required = 4 hours

Hence, Meena will require 4 hours to drive 196 miles.

What is inequality form ?

The notation a ≠ b means that a is not equal to b; this inequation sometimes is considered a form of strict inequality. It does not say that one is greater than the other; it does not even require a and b to be member of an ordered set.

What is interval notation?

Interval notation is a way to describe continuous sets of real numbers by the numbers that bound them. Intervals, when written, look somewhat like ordered pairs. However, they are not meant to denote a specific point. Rather, they are meant to be a shorthand way to write an inequality or system of inequalities.

The hour hand that goes through 3 right angles and starts from 7 will stop at 4.

We can assume that the numbers in a clock are positioned in a circle. The angle in a circle is 360⁰, while the numbers in a clock is 12.

Hence, from each clock number to its consecutive number, the hour hand must travel 30⁰ as shown in the attached picture.

A right angle is equal to 90⁰. This is equal to 3 ⨉ 30⁰. In other words, to travel  90⁰ means to travel 3 hours.

3 right angles =  3 ⨉ 90⁰

                      = 3 ⨉ 3 hours

                      = 9 hours.

Thus, the hour hand will go to:

7 + 9 = 16

16 is equal to number 4 in a clock number.

The required solution of the given quadratic equation is [tex]{\displaystyle x={\frac {2\ - {\sqrt {(-32)}}}{2}}[/tex] and  [tex]{\displaystyle x={\frac {2\ + {\sqrt {(-32)}}}{2}}[/tex]

In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation.

Given a general quadratic equation of the form

ax^2 + bx + c = 0

with x representing an unknown, with a, b and c representing constants, and with a ≠ 0, the quadratic formula is:

[tex]{\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}[/tex]

and,

Now the given quadratic equation is,

x^2 - 2x = - 9

or,  x^2 - 2x + 9 = 0

here, a = 1

b = -2

c = 9

Thus quadratic formula is given as,

[tex]{\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}[/tex]

[tex]{\displaystyle x={\frac {-(-2)\pm {\sqrt {(-2)^{2}-4*1*9}}}{2*1}}[/tex]

[tex]{\displaystyle x={\frac {2\pm {\sqrt {4-36}}}{2}}[/tex]

The equation given as 2/(7 - m) = 4/(m - 5) - m/(7 -m) has no real solution for m

The equation is given as

2/(7 - m) = 4/(m - 5) - m/(7 -m)

Take the like terms of the above equation

So, we have

m/(7 -m) + 2/(7 - m) = 4/(m - 5)

Evaluate the like terms in the above equation

So, we have

(m + 2)/(7 -m) = 4/(m - 5)

Cross multiply the above equation

So, we have

m^2 + 2m - 5m - 10 = 28 - 4m

Evaluate the like terms

m^2 + m + 18 = 0

Using a graphing tool, we have no solution for m

Hence, the equation given as 2/(7 - m) = 4/(m - 5) - m/(7 -m) has no real solution for m
