2.6\le2.6 classifies as \text{true}

-6 classifies as \text{false},

3.1>-3.1 classifies as \text{true}

so -5\ge -5 classifies as \text{true}

To classify the statements, we need to evaluate each of them:

\text{Evaluate }2.6\le2.6\\\implies (2.6

so 2.6\le2.6 classifies as \text{true}, since the statement also allows 2.6 to be equal to itself.

\text{Evaluate }-6

so -6 classifies as \text{false}, since -6 is equal to itself, not smaller.

\text{Evaluate }3.1>-3.1\\\implies \text{true}

so 3.1>-3.1 classifies as \text{true}, since x>-x, for all real numbers

\text{Evaluate }-5\ge-5\\\implies (-5>-5)\text{ or }(-5=-5)\\\implies \text{false  or  true}\\\implies\text{true}

so -5\ge -5 classifies as \text{true}, since the statement also allows -5 to be equal to itself.

The regular price of a DVD is $26 the week after the DVD is on sale for $19.50 how many times the regular price is the sale of t
scoray [572]
Regular price= x times of sale price
26=x times 19.50
divide both sides by 19.50
1.33333333333333333=x

so it is 1.33333 times the sale price or 4/3

The quadrilateral shown is a rectangle. What is the measure of PR? (round to the nearest hundredth)
sladkih [1.3K]

Option B) 37.12 is the right answer

Step-by-step explanation:

It is given that the qudrilateral is a rectangle which means that opposite sides wil be equal and all interior angles will be 90 degrees

So

PS = 17

PQ = SR = 33

The diagonal PR will form a right-angles triangle with PR being the hypotenuse

So,

Base = SR = 33

Perpendicular = PS = 17

Hypotenuse = PR = ?

The Pythagoras theorem will be used to find the length of PR

So,

H^2 = B^2+P^2\\(PR)^2 = (SR)^2 + (PS)^2\\PR^2 = (33)^2+(17)^2\\PR^2 = 1089+289\\PR^2 = 1378\\

Taking square root on both sides

\sqrt{PR^2} = \sqrt{1378}\\PR = 37.1214

Rounding off to nearest 100th

PR = 37.12

Hence,

Option B) 37.12 is the right answer

Explain why multiplying 37.4×0.1 gives a product that is less than 37.4
Yuliya22 [10]
Multiplying by 0.1 is the same as dividing by 10, as 0.1 = 1/10 

So, 37.4x 0.1 = 37.4/10 = 3.74

The sum of the measures of the interior angles of a convex polygon is 2160. how many sides does the polygon have?
horsena [70]
<span>Sum of Interior Angles = (Number of Sides -2) • 180 degrees
2,160 = (sides -2) * 180
2,160 / 180 = sides -2
12 = sides -2
sides = 14
