Answer:

When we have a function y = f(x)

The set of the possible values of x is called the domain, and the set of the possible values of y is called the range.

In this case, we have:

x = age, and y =  price.

x                    y

< 5              $0

5 - 17          $25

18 - 64         $40

≥ 65            $35

Then the range is the possible age of the customer, and it goes for all the possible ages (as whole numbers)

So the domain will be the set of all the positive integers:

D = {1, 2, 3, 4, 5, ...}

(of course, we can not have an age equal to 1300 or infinity, but we really can not cap the domain)

The range is the possible values of y, in this case is discrete, because we have only 4 possible prices, so the range is:

R = {$0, $25, $40, $35}

y=mx+b

We have twice Gali's score, which is 2 multiplied by g, which we can write as 2g.

We increase 23 by 2g, which means, we add.

Answer:

23+2g

Step-by-step explanation:

Let g = gali's score

[tex]twice \:gali\: score = 2\times g\\\\= 2g[/tex]

In a year with 365 days, it should rain for about 240 of those days for the given condition.

It is the ratio of two integers expressed as a decimal fraction of a whole number. It is a statistic for contrasting two sets of data, and the % sign is used to describe it as a percentage. Percentages are often and creatively used. For instance, a lot of data is published as percentages in the media, including bank interest rates, retail discounts, and inflation rates.

It is supposed to rain 66% of the time in Seattle, Washington. Considering that there are 365 days in a year,

Suppose the number of days is it expected to rain obtained be x,

x=66% of 365

x=66/100 × 365

x=240,9 ≈ 240

Thus, it should rain for about 240 days.

Answer:

0.34%

Step-by-step explanation:

1. Start by representing the percentage with the variable, x %. Using x%, create an algebraic expression.

    29% X x = 3

2. Solve for x by dividing both sides by 29.

   29x divided by 29 =3 divided by 29.

             x=0.1034

3.Convert 0.1034 into a percentage by multiplying the decimal by 100%

             X =0.1034 x 100%

                  x=10.34%

the sum of the internal angles of a triangle are equal to 180 degrees.

once i remembered that the problem became a lot easier.

let a, b, and c be the angles of the triangle.

-----

let a = 2*b

-----

let c = a+b-12

-----

the above two statements are given.

since the sum of the internal angles of a triangle are equal to 180, then we have a third equation to work with which is

-----

a + b + c = 180

-----

we now have 3 equations for 3 unknowns and we should be able to solve for each of the unknowns.

-----

it looks like the easiest thing is to solve for b. once we find b, the rest should fall into place very nicely.

-----

since a = 2*b, we can substitute 2*b for a in the equation a + b + c = 180.

that equation then becomes 2*b + b + c = 180 which becomes 3*b + c = 180.

looking at the equation c = a + b - 12, we solve for b as follows:

since we know that a = 2 * b, we can substitute 2*b for a and the equation becomes c = 2*b + b - 12 which becomes c = 3*b - 12.

-----

the equation we are working with is 3*b + c = 180 which originally started as a + b + c = 180.

we can substitute 3*b - 12 for c and the equation becomes

3*b + 3*b - 12 = 180 which becomes 6*b = 192 after adding 12 to both sides and combining like terms.

dividing both sides of the equation by 6 and we get b = 32 degrees.

-----

we have b = 32 degrees.

we have a = 2 * b so a = 64 degrees.

we have c = a + b - 12 which becomes c = 32 + 64 - 12 which becomes c = 96 - 12 which becomes c = 84 degrees.

-----

substituting in the equation a + b + c = 180, we get 32 + 64 + 84 = 180 which becomes 96 + 84 = 180 which becomes 180 = 180.

Step-by-step explanation:

Answer:

x = 6

Step-by-step explanation:

1/4 (x-2) + 5 = x

1/4 (x-2) = x - 5

x - 2 = 4(x-5)

x-2 = 4*x + 4*-5

x-2 = 4x - 20

x - 4x = 2 - 20

-3x = -18

x = -18/-3

x = 6

Check:

1/4(6-2) + 5 = 6

1/4(4) + 5 = 6

First problem: 1088 [tex]m^{3}[/tex]

Second problem: 554.3 [tex]m^{3}[/tex]

Step-by-step explanation: Please see the images below!

The volumes of both the pyramids are 1088 m³ and 554.3 in³.

The volume of a shape or solid is the space occupied by it, which also includes its height or depth.

a) To find the volume of the pyramid, first calculate the area of the base.

B = lw

Substitute 16 for l and 12 for w.

B = 16 ⋅ 12

Simplify.

B = 192 m²

To find the volume of the pyramid, use the formula for the volume of a pyramid.

V = 1/3 Bh

Substitute 192 for B and 17 for h.

V = 1/3 ⋅ 192 ⋅ 17

Simplify.

V = 1088 m³

Therefore, the volume of the rectangular pyramid is 1088 m³.

b) Similarly for the volume of a regular hexagonal pyramid with base edge length 8 in. and height 10 in.

Base area = 96√3 in²

Volume = 1/3 × 96√3 in² × 10 in

= 554.3 in³

Hence, the volumes of both the pyramids are 1088 m³ and 554.3 in³.
