prove that the sum of the lengths of the diagonals of a quadrilateral is less than the perimeter but greater than the half of the perimeter of this quadrilateral
Answers
Let us consider a quadrilateral ABCD (as shown in the figure below) such that AC and BD are the two diagonals of ABCD.
Now, in triangle ABC and triangle ADC, by using the properties of triangle inequality we have-
AB +BC > AC .... (1)
and AD + CD >AC .... (2)
adding equations (1) and (2) we get-
AB+ BC+CD+AD > 2AC .... (3)
Similarly for diagonal BD we get-
AB+BC+CD+AD > 2BD .... (4)
Adding equations (3) and (4) we get-
2(AB+BC+CD+AD) > 2(AC+BD)
⇒ (AB+BC+CD+AD) > AC+BD
here (AB+BC+CD+AD) = perimeter of quadrilateral.
Hence, we have proven that the sum of the length of the diagonals of a quadrilateral is less than the perimeter.
Now the 2 diagonals divide the quadrilateral into 4 quadrilaterals
Therefore, AO+OD > AD
OD+OC > CD
OC+OB > BC
and OA+OB > AB
Adding all these equations-
2(AC+BD)>AB+BC+CD+AD
⇒AC+BD > 1/2(AB+BC+CD+AD)
Hence, we've proven that the sum of the length of the diagonals is greater than the half of the perimeter of this quadrilateral.

Modulus (mod) symbol is a symbol that is used to find the remainder of the quotient of two integers
6mod6 means we need to find the result of the remainder if 6 is divided by 6.
Take the ratio of the integers
6/6 = 1.0
Multiply the result by the denominator
1.0 * 6 = 6
Take the difference of the result and the denominator
Remainder = 6 - 6
Remainder = 0

we see that
m<4 and m<3 are alternate interior angles

so
m<3=39 degreesPart 3
we see that <2 and <5 are alternate interior angles

A pizza parlor offers a choice of 12 different toppings. How many 2-topping pizzas are possible? (no double-orders of toppings are allowed)
Answers
==========================================================
Explanation:
There are 12 choices for the first topping and 11 for the next topping. The decrease is to account for the fact we cannot select a repeat topping.
That gives 12*11 = 132 permutations. If order of toppings mattered, then this would be our final answer.
However, the topping order doesn't matter. So we need to divide by 2 to correct for the double counting.
There are 132/2 = 66 combinations.
------------
Alternative Method:
n = 12 toppings are available and r = 2 selections are allowed
Order doesn't matter so we use the nCr combination formula
[tex]n C r = \frac{n!}{r!(n-r)!}\\\\12 C 2 = \frac{12!}{2!*(12-2)!}\\\\12 C 2 = \frac{12!}{2!*10!}\\\\12 C 2 = \frac{12*11*10!}{2!*10!}\\\\ 12 C 2 = \frac{12*11}{2!}\\\\ 12 C 2 = \frac{12*11}{2*1}\\\\ 12 C 2 = \frac{132}{2}\\\\ 12 C 2 = 66\\\\[/tex]
There are 66 combinations

,• Cost of gas = $3.59 per gallon
,• Vehicle gets 15 miles per gallon.
Let's calculate the cost per person for this trip.
We have the following:
To find the total cost of gas they used for this trip, we have:
[tex]\frac{380}{15}*3.59=90.95[/tex]The total cost of gas for this trip is $90.95
The cost of gas per person will be:

Therefore, the cost per person for this trip will be:
Cost per person = Cost of gas per person + Cost of meal per person

Answers
If the cost of fertilizer is $2.68 per square foot of coverage then the farmer need to spend an amount of $5085.3 to apply fertilizer to the entire patch.
Given that the farmer Anders' pumpkin patches are such that they are in rectangle and the lengths are 19 yards and 48 yards and the breadths are 11 yards and 22 yards.
We are required to find the amount of money that the farmer need to spend to apply the fertilizer to the entire patch.
Area which is covering the entire patch=11*19+22*48
=209+1056
=1265 square yards
We know that 1 yard=3 foot
Area in foot=1265*3
=3795 square foot
Amount for fertilizer=3795*3
=$10170.6
Since 1/2 is off so it will be $5085.3 ($10170.6/2).
Hence if the cost of fertilizer is $2.68 per square foot of coverage then the farmer need to spend $5085.3 to apply fertilizer to the entire patch.
