Answer:

Option B.

Step-by-step explanation:

If you begin with one dollar a day there will get you more by the end of the month because on day 2 your on 201 already which is more than you get in that month with one cent.

The first option (A) will give you more money than option (B).

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).

Given that

Case A). Doubling each day

1 + 2+ 4 + 8 + 16 .... it is form a GP series with common ratio (r) 4/2 = 2

Number of terms (n)

Sum =  30( [tex]2^{30}[/tex] - 1)/(2 - 1) = $2147483464.

Case B). Adding $100 each day

1 + (101 + 201 + 301 ....) it is form a ap series with common difference d = 201 - 101 = 100.

Number of terms = 29

Sum = 1 + 29/2 + [ 2 (101) + 28(100)] = $43530

Hence it is clear that case (A) will give you more money.

#SPJ5

Answer:  ∠1 = 52°, ∠4 = 40°, ∠7 = 100°, ∠10 = 49°, ∠13 = 65°

Step-by-step explanation:

There are three formulas you need to find the angles. Each formula is based on where the vertex lies.

On the circle: Measure of the angle = (1/2) the arc (Images 1-3)

∠4 = (1/2)°80             ∠10 = (1/2)(18° + 80°)           ∠13 = (1/2)130°

    = 40°                           = (1/2)98°                            = 65°

                                       = 49°

Inside the circle: (1/2) Sum of the Big arc and Little Arc (Image 4)

∠7 = (1/2) (130° + 70°)

    = (1/2)200°

   = 100°

Outside the circle: (1/2) Difference of Big arc and Little Arc (Image 5)

∠1 = (1/2)[(62° + 130°) - (70° + 18°)]

    = (1/2) (192° - 88°)

   = (1/2)104°

   = 52°

I can only add 5 attachments.  If you want to see image 6 (which contains the measures for all of the angles), you will need to ask the question again.  Sorry!

Answer:

Heather's polygon has 3 sides.

Step-by-step explanation:

S = 60x       Try plugging in number for x that will work

I found that when x = 3, the equation was true

S = 60x     Substitute

S = 60(3)   Multiply

S = 180      If the sum of the interior angles is 180, the only shape that can be made is a triangle, which has 3 sides.

Answer:

x=45

Step-by-step explanation:

the sum of straight angle=180

2x+45+x=180

3x=180-45

3x=135

x=135/3=45

Answer:

45 degree

Step-by-step explanation:

Since it is an straight line it means all of the added angles together equal 180

2x+45+x=180

3x+45=180

3x=135

x=135/3

x=45

C

Step-by-step explanation:

You can see that both of the numbers are being multiplied by 4/4 which gives you a proportional relationship unlike the other answers there.

Answer:

Step-by-step explanation:

Given the equation d/10 = 12. To get the value of d, the follwoing steps can be used to solve for the value of d;

Multiply both sides by 10

d/10 * 10 = 12*10

d = 120

It can be seen from the calculation above that multiplication operation was used to get the solution to the equation. It can therefore be concluded that the multiplication property of equality  was used to solve the equation.

Answer:

Reflection.

Step-by-step explanation:

The reflection of the point (x,y) across  the x-axis is the point (x,-y).

The reflection of the point (x,y) across  the line y = x is the point (y, x).

Given the preimage (2,-3).

Therefore, the type of transformation that has occured is Reflection.

Answer:

KM = 15

Step-by-step explanation:

From the diagram, ΔJKL and ΔJKM are similar to each other because they share the same angle J and they are both right angle triangle. Therefore they are similar by AA property.

Since JL=25 and JM=5, JM = JL + JM= 25 + 5 = 30

Since ΔJKL and ΔJKM are similar to each other, therefore:

[tex]\frac{JK}{JL}=\frac{JM}{JK}\\ Substituting:\\\frac{JK}{30}=\frac{5}{JK}\\JK^2=150\\JK=\sqrt{150}\\ \\From\ hypotenuse:\\JK^2=JM^2+KM^2\\Substituting:\\(\sqrt{150} )^2=5^2+KM^2\\150=25+KM^2\\KM^2=150-25=125\\KM=\sqrt{125}\\ KM=15[/tex]

Answer:

D.   22.5 sq. un.

Step-by-step explanation:

W divides BU so that there is a ratio of 1;2 meaning that there are 3 parts.

That means that 3 parts is BUV; we know that one of those parts is 4.5 sq. un. so 4.5*3=13.5 sq. un.  - Also 4.5*2=9 to get WUV

V is the midpoint of the line BS so that means that BUV and UVS are equal

we know that BUV is 13.5 so we multiply that by 2 to get the whole triangle

=27

The last step is to get rid of BVW which we know is 4.5

27-4.5=22.5

The slope of a line is the average rate of change of the line.

The graph that represents [tex]\mathbf{y = x - 2}[/tex] is graph (a)

The line equation is given as:

[tex]\mathbf{y = x - 2}[/tex]

To do this, we simply test the options until we get the correct graph

(a) Line that passes through (-2,-4) and (0,-2)

This means that:

[tex]\mathbf{(x_1,y_1) = (-2,-4)}[/tex]

[tex]\mathbf{(x_2,y_2) = (0,-2)}[/tex]

Substitute values for x1 and y1 in [tex]\mathbf{y = x - 2}[/tex]

[tex]\mathbf{-4 = -2 - 2}[/tex]

[tex]\mathbf{-4 = -4}[/tex]

This point is true for [tex]\mathbf{y = x - 2}[/tex]

Substitute values for x2 and y2 in [tex]\mathbf{y = x - 2}[/tex]

[tex]\mathbf{-2 = 0 - 2}[/tex]

[tex]\mathbf{-2 = - 2}[/tex]

This point is also true for [tex]\mathbf{y = x - 2}[/tex]

Hence, the graph that represents [tex]\mathbf{y = x - 2}[/tex] is graph (a)

See attachment for the graph of [tex]\mathbf{y = x - 2}[/tex]

Answer:

85 ft^2

Step-by-step explanation:

Let us calculate the area of the triangles and the base.

For the triangles, we can use the area formula and get 5 • 3 which is 15. Since there are 4, we multiply it by 4 and get 60.

For the base, we have 5 • 5, which is 25. Adding it together, we get 85.

If you are stuck on how to find surface area, all you have to do is find the area of each side and add.

Answer:

[tex]y=\frac{-5}{2}x+1.5[/tex]

Step-by-step explanation:

Well the equation we have [tex]y-4=\frac{-5}{2}(x-2)[/tex] is in slope-point form so we have to transfer it to slope intercept look at the first image below to see how I got [tex]y=\frac{-5}{2}x+9[/tex].

So we know that line T which is parallel to line S crosses through point (-1,4)

and we know that the slope stays the same and that its the y intercept has to change so the answer is [tex]y=\frac{-5}{2}x+1.5[/tex]. Look at the image second below.

Answer:

h = 1.38 cm

Step-by-step explanation:

The question is at what value is the height of both cylinders the same:

The area of the circular base on each cylinder is:

[tex]Area=\pi r^2\\A=4\pi \ cm^2\\B=25\pi \ cm^2[/tex]

The initial volume in cylinder A is:

[tex]V=4\pi *10\\V=40\pi\ cm^3[/tex]

We have that Va + Vb = 40π. The height of water in each cylinder as a function of volume is:

[tex]h_A=\frac{V_a}{4\pi}\\h_B=\frac{V_b}{25\pi}[/tex]

If both heights are the same:

[tex]\frac{V_a}{4\pi}=\frac{V_b}{25\pi}\\V_b=\frac{25}{4}V_a \\V_a+V_b=40\pi\\V_a+\frac{25}{4}V_a=40\pi\\V_a=5.5172\pi\ cm^3[/tex]

The height 'h' is:

[tex]h=\frac{5.5172\pi}{4\pi}\\ h=1.38\ cm[/tex]
