When both bags weigh over 50 pounds when the passenger approaches the check in counter, the person will pay an extra charge.

It should be noted that one will pay for an excess luggage when the luggage is heavier than the allowance when the person checks in.

It should be noted that every airline has a restriction on how heavy the luggage can be.

Therefore, when both bags weigh over 50 pounds when the passenger approaches the check in counter, the person will pay an extra charge.

Answer: Small box has the lowest amount when divided, that box has the best value.

Step-by-step explanation:

Given data,

Big box = 500 g

It cost is $8.00

Small box = 300 g

It cost is $ 5.40

First switch the box that's in kilograms into grams.

One kilogram=1000 grams.

Then,    Big box = 500 g = $ 8.00

            Small box = 300 g = $ 5.40

Next divide the amount in each box by the cost of each box.

           Big box = 500/8

           Big box  = 62.5

           Small box = 300/540

           Small box  = 0.5555

Therefore,

So, since small box has the lowest amount when divided, that box has the best value.

The following set of numbers, 15, 36, and 39, can be the measures of the sides of a right triangle.

A triangle is a polygon with three sides and three vertices.

To know if a set of number is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.

let a = 15, b = 36, and c = 39

a + b > c     15 + 36 > 39     51 > 39     True

a + c > b     15 + 39 > 36     54 > 36     True

b + c > a     36 + 39 > 15     75 > 15     True

To know what type of triangle based on the length of its side:

1. Take the sum of the squares of the two smaller sides.

15^2 + 36^2 = 1521

2. Compare it to the square of the largest side.

39^2 = 1521

1521 = 1521

If the sum of the squares of the 2 is larger than the square of the 3rd, it is an acute triangle.

if they are equal, it is a right triangle

if they are smaller, then it is an obtuse triangle.

Hence, 15, 36, and 39 can be the measure of the sides of a right triangle.

Answer:

A=h(b+c) solve for c

First, multiply h to b and c

A = hb + hc

Then, transfer hb to the other side and change its sign from positive to negative.

A – hb = hc

To get c, Divide both sides by h

(A – hb)/h = hc/h

(A - hb)/h = c  OR c = (A – hb)/h

Example. Let us assume the following. A = 500 ; h= 10;b= 20; c= ?

c = (A – hb)/h

c = (500 – (10*20))/10

c = (500 – 200)/10

c =  300/10

c = 30

To check; use the original equation given.

A = h(b+c)

A = 10(20+30)

A = 200 + 300

A = 500. same as the figure given in the example.

In Geometry, two (2) triangles are similar when the ratio of their corresponding sides are equal in magnitude and their corresponding angles are congruent.

In Mathematics, two geometric figures are considered to be congruent only when their corresponding side lengths are congruent and the magnitude of their angles are congruent.

Triangle midpoint theorem states that the line segment which connects the midpoints of two (2) sides of a triangle must be parallel to the third side, and it's congruent to one-half of the third side.

In triangle BCD,

∠CBD=34° (isosceles triangle)

∠DCB=116° (sum of angles in a triangle)

Answer:

4.59 cm to nearest hundredth.

Step-by-step explanation:

Consider triangle ABD.

sin 72 = DB / 8

DB = 8 sin 72

      = 7.608 cm.

Imagine a line from point C perpendicular to DB at point E.

As triangle CDB is isosceles ( DC = BC), this line will cut DB in 2

so, DE = 1/2 * 7.608 = 3.804.

Now consider triangle DCE which is a right-angled triangle at E.

cos 34 = 3.804 / DC

DC = 3.804 / cos 34

      = 4.588 cm

BC = DC = 4.588.

The problem statement provides information about the Vasquez Family, who pay visits to their grandmother every three weeks and host a neighborhood party every eight weeks.

The number of weeks combined when the Vasquez Family visits their grandmother and hosts the neighborhood party is 24 weeks.

The total number of weeks with all the three events occurring together (visit, neighborhood party, hiking) is 48 weeks.

Now we concluded that the number of weeks is 24 because we know that the Vasquez family visits their grandmother every three weeks and hosts a neighborhood party every eight weeks.

Therefore,  we will look for a least common factor of both 3 (visit) and 8 (party) and that LCM (least Common Factor) is 24.

The distance between pair of parallel lines with the following equation

y=x+2 y=x-4  is  [tex]3{\sqrt 2 }[/tex]

​

Parallel lines are any two or more lines that lie in the same plane but never cross one another. Both have the same slope and are equally distant from one another. No matter how far we extend a parallel line, it will always remain straight.

The fundamental characteristics listed below make it simple to recognize parallel lines.

The slope of a line which is perpendicular to both the lines will be -1. Check what are the y-intercept of any of the two lines and write the equation of the perpendicular line through it.

The y-intercept of the line y = x − 4 is (0,−4).

So, the equation of a line with slope −1 and a y-intercept of −4 is y = −x −4.

The perpendicular intersects or meets the line y = x - 4 at (0, 4).

Now, to find the point of intersection of the perpendicular & the other line, solve the two equations. Solve the right sides & solve for x.

x + 26 = -x - 6

     2x = -6                                       (combine them like terms)

       x = -3                                       (divide both the side by 2)

Find y:

y = -3 - 4

  = -7

So, the point of intersection is (−3,−7).

Use the Distance Formula to find the distance between the points (-3, -7) and (0,−4).

The area of the parallelogram is approximately equal to 59.994 square units.

The area of a parallelogram is equivalent to the sum of the areas of the two triangles by adding a diagonal. Then, the area of each triangle can be found in terms of side terms by Heron's formula. First, find the length of each side:

Side AB

AB = (4, 6) - (- 2, 6)

AB = (6, 0)

AB = √(6² + 0²)

AB = 6

Side CD

CD = (- 1, - 4) - (5, - 4)

CD = (- 6, 0)

CD = √(6² + 0²)

CD = 6

Side AD

AD = (- 1, - 4) - (- 2, 6)

AD = (1, 10)

AD = √(1² + 10²)

AD = √101

Side BC

BC = (5, - 4) - (4, 6)

BC = (1, - 10)

BC = √[1² + (- 10)²]

BC = √101

Side AC

AC = (5, - 4) - (- 2, 6)

AC = (7, - 10)

AC = √[7² + (- 10)²]

AC = √149

Second, determine the areas of the two triangles.

Triangle ABC

s = 0.5 · (AB + BC + AC)

s ≈ 14.128

A = √[s · (s - AB) · (s - BC) · (s - AC)]

A ≈ 29.997

Triangle ACD

s = 0.5 · (AC + CD + AD)

s ≈ 14.128

A = √[s · (s - AC) · (s - CD) · (s - AD)]

A ≈ 29.997

Third, find the area of the parallelogram by adding the two areas calculated in the previous step:

A' = 29.997 + 29.997

A' = 59.994

The area of the parallelogram is approximately equal to 59.994 square units.
