Answer:

2. 4a+2c = 5000

4. a + c = 1600

Step-by-step explanation:

Answer:

2.) 4a+2c=5,000

4.) a+c=1,600

Step-by-step explanation:

4 times a(adults) plus 2 times c(children)=5,000

4 is from $4 per adult(a) and 2 is from $2 per children(c).

a+c=1,600

You can add the number of adults and children to find the answer.

What is dilation?

Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor.

The new figure obtained after dilation is called image.

Scale factor is the ratio of the sizes of the original figure with the dilated figure.

[tex]scale factor = \frac{dimension of new shape }{dimension of original shape}[/tex]

According to the given question

Volume of solid = 6 cubic units

Surface area of solid = 22 square units

volume of image = 48 cubic units

therefore,

ratio of volumes = ratio of lengths

[tex]\frac{48}{6}[/tex] [tex]=8:1[/tex]

⇒ratio of sides = [tex]\sqrt[3]{8} :\sqrt[3]{1}[/tex]

⇒ ratio of sides = 2 : 1

Ratio of surface area of solid and image = square of ratio of sides = 4:1

⇒[tex]\frac{surface area of image }{surface area of solid} = \frac{4}{1}[/tex]

⇒[tex]\frac{surface area of image }{22} = \frac{4}{1}[/tex]

⇒ surface area of image = 4×21

⇒ surface area of image = 81square units.

Answer:

528  dollars

Step-by-step explanation:

The starting price is $600. And it goes down by 20% then comes back up 10% so steps are:

First we got 20% off so I did 100 - 20 and got 80%

1: 80%  * 600 = 80/100 * 600 = 480

Then we get an increase of 10% so I multiplied 110% with 480 which was our new price

2. 110/100 * 480 = 11 * 48(simplifying)

=  528

Answer:

this is irregular shape it has four vertix and two faces

The number of vertices and faces this shape have is 4 and 4.

Faces are planar mathematical objects. Like a triangle, a rectangle etc. Edges are those line segments, which are on the edge of the faces (of some object considered).

Vertices are points of intersections of different edges.

We are given that;

The figure

Now,

Number of vertices= 3+1

=4

Number of faces= 3+1

=4

Therefore, by vertices the answer will be 4 and 4.

Answer:

C

Step-by-step explanation:

First, we have to find the equation that will give the rabbit population as a function of time and the initial population.

The equation we need turns out to be Population = a0 x 3y  where a0 is the initial population and y is the number of years,

To find the rabbit population when a0 = 30 and y =3, use the equation to get Population = 30 x 33 = 810.  

You can now find the difference in the number of rabbits at year 3 for the different starting populations.

Answer:

k=1

Step-by-step explanation:

Simplify   1/k

(((—+2)-(—•k))-4)-(—-2)  = 0

2.1   Subtracting a whole from a fraction

     2     2 • k

  2 =  —  =  —————

       1       k  

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

1 - (2 • k)     1 - 2k

———————————  =  ——————

6.1   Subtracting a whole from a fraction

7.1   Subtracting a whole from a fraction

3 + 2 • k     2k + 3

—————————  =  ——————

   k           k  

8.1       Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

       2     2 • k

  2 =  —  =  —————

       1       k  

9.1     Pull out like factors :

 2 - 2k  =   -2 • (k - 1)

10.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

-2•(k-1)

———————— • k = 0 • k

   k    

Now, on the left hand side, the  k  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

 -2  •  (k-1)  = 0

Equations which are never true:

10.2      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

10.3      Solve  :    k-1 = 0

Add  1  to both sides of the equation :

                    k = 1

Step-by-step explanation:

Equations are expressions separated by an equal sign. The value of k that will make the equation true is -1

Given the equation expressed as

5−k+12=16

We need to find the value of "k" that will make the equation equal

Given

5−k+12=16

Collect the like terms

17 - k = 16

Subtract 17 from both sides

17 - k - 17 = 16 - 17
k = 16 - 17
k = -1

Hence the value of k that will make the equation true is -1
