Step-by-step explanation:

Answer:

Yes, it would still be considered a hexagon. The reason why we require "6 angles" is probably just because you don't want the 6 lines to cross and create "more than 6 angles". The hexagons you are probably thinking of (the one with all the angles and sides equal) would be regular hexagons.

Step-by-step explanation:

5⁴(3406 - 867) + (1.9 x 6)

=625(2539) + 11.4

= 1586875 + 11.4

=1586886.4

Answer:

= 1586886.4

Step-by-step explanation:

5^4 = 5 x 5 x 5 x 5
= 625

625(3406 - 867)
625 x 3406
= 2128750

625 x 867
= 541875

2128750 - 541875
= 1586875

1.9 x 6
= 11.4

1586875 + 11.4
= 1586886.4

Step-by-step explanation:

inequalities follow basically the same rules as equalities (ahem, equations). for creation and calculation.

you just indicate whole areas above or below given lines.

behind every inequality is a "normal" equation that defines the delimiter.

the question already tells us which variables to use.

x = number of hot dogs

y = number of peanuts (I guess, bags of peanuts)

he wants to buy at least 4 snacks.

hmmm.

what would you do, if the question asked us :

he wants to buy 4 snacks.

what did you learn from the previous questions ?

the equation would be

x + y = 4.

but now it asks us about "at least" 4 snacks. so every solution, 4 or more, is valid. not only 4.

so, the inequality is

x + y >= 4

and he has $20 to buy these snacks.

again, with equations we would have said

3x + 2y = 20

remember, a hot dog costs $3, a bag of peanuts costs $2. so, every single hot dog and every single bag of peanuts brings itself into the cost calculation with that amount.

x hot dogs cost $3x. y bags of peanuts cost $2y.

but here, we are now flexible. he can spend $20, but he does not have to fully exceed his budget. he can also spend less.

so, the inequality is

3x + 2y <= 20

together these inequalities now describe the situation that he cannot spend more than $20, but he can spend as little as he wants, as long as he gets at least 4 snacks.

all combinations of x and y values that satisfy these conditions are valid solutions.

the actual solution would be then more complex, as the real life scenario gives us more constraints :

0 <= x <= 6 (because with more than 6 hot dogs alone he would already bust his budget).

0 <= y <= 10 (after buying 10 bags of peanuts the $20 are gone).

that eliminates the negative value solutions that the basic 2 equations would allow.

Answer:

P   = 6 2/3 ft

Step-by-step explanation:

The formula for the perimeter of a rectangle of length L and width W is

P = 2(L + W).

Here the perimeter is P = 2(1 2/3 + 5/6) = 2(5/2 + 5/6)

                                                                  = 2(15/6 + 5/6) = 2(20/6)

                                                                  = 40/6 = 20/3

                                                              P   = 6 2/3 ft

Answer:

Step-by-step explanation:

calculate the distance using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+( y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = A (5, 1 ) and (x₂, y₂ ) = B (- 3, - 3 )

AB = [tex]\sqrt{(-3-5)^2+(-3-1)^2}[/tex]

     = [tex]\sqrt{(-8)^2+(-4)^2}[/tex]

     = [tex]\sqrt{64+16}[/tex]

     = [tex]\sqrt{80}[/tex]

     = [tex]\sqrt{16(5)}[/tex]

     = [tex]\sqrt{16}[/tex] × [tex]\sqrt{5}[/tex]

     = 4[tex]\sqrt{5}[/tex] → A

Answer: $51,800

Step-by-step explanation:

if the value increases by 10% every year, we can represent this as a linear function, in the form:

y = mx + b

y = [0.1(37,000)]x  + 37,000

0.1 x 37000 represents the 10% increase per year, and x represents the number of years that have passed. we add 37,000 at the end to represent the original cost of the painting.

we can simplify the 0.1(37,000) to 3700, which is how much the painting's cost should increase per year. so our equation is:

y = 3,700x + 37,000

So, in 4 years, the painting will be worth:

y = 3,700(4) + 37,000

14,800 + 37,000

Answer:

There are 801 box seats and 9612 regular seats.

explanation:

Let the number of box seats be x,

Then the regular seats is 12x

The sum of seats equals to 10,413

Solve:

12x + x ➙ 10,413

13x ➙ 10413

x ➙ 801

There are 801 box seats.

Find for regular seats:

➙ 12(x)

➙ 12(801)

➙ 9612

There are 9612 regular seats.

The difference in volume of the two compartments is 210 cm³

Volume is the amount of space occupied by a three dimensional shape or figure.

The volume of the compartment = area of base * height

Area of base (trapezoid) = (1/2)(sum of parallel side)(height) = (1/2) * (15 + 5) * (7) = 70 cm²

Volume of compartment = 70 * 8 = 560 cm³

For the new compartment, height = 8 + 3 = 11 cm, hence:

Volume of new compartment = 70 * 11 = 770 cm³

Difference in volume = 770 cm³ - 560 cm³ = 210 cm³

The difference in volume of the two compartments is 210 cm³

Considering that we have two samples, and the standard deviation for each sample, the correct test is given by:

iii. A two-sample -interval for a difference between population means.

Here, there are two samples, and we will investigate their difference. The information taken from the sample is expanded to the population, and since we have the standard deviation for each sample, a t-test is used, hence the correct option is given by:

iii. A two-sample -interval for a difference between population means.
