Hope this helps yall! Have an Amazing day!!

Given :

John can play 12 songs on his guitar but learns 1 new song every week. Aiden can play 4 songs but learns 2 every week.

To Find :

How many weeks will it be before Aiden knows as many songs as john?

Solution :

Let, after x weeks Aiden know a songs and John know j songs.

The linear equation for both the situation is :

a = x + 12       .....( For Aiden )

j = 2x + 4       ......( For John )

We need to find in which week Aiden knows as many songs as John.

For this , a = j

x + 12 = 2x + 4

x = 8

Therefore, in 8th week both of them know the same number of songs.

-Number 2 is Power of a Power Property

Answer: Convex

Step-by-step explanation  

The difference between convex and concave polygons lies in the measures of their angles. Another way to think of it is this: the diagonals of a convex polygon will all be in the interior of the polygon, whereas certain diagonals of a concave polygon will lie outside the polygon, on its exterior .Also If the interior angles of of the polygon are less than 180 degrees, then the polygon is convex. But if any one of the interior angles is more than 180 degrees, then the polygon is concave. T∴×∴T that was a lot

Answer:

Angle B = 47.3°

Step-by-step explanation:

We are to find Angle B

b = 6.8cm

C = 70°

c = 8.7cm

We solve using Sine rule

b/sin B = c/ sin C

6.8/sin B = 8.7/sin 70

Cross Multiply

sin B × 8.7 = 6.8 × sin 70

sin B = 6.8 × sin 70/8.7

B = arc sin ( 6.8 × sin 70/8.7)

B = 47.26265°

Approximately to 3 significant figures

= B = 47.3°

Answer:

2100

Step-by-step explanation:

6300/3

Answer:

Step-by-step explanation:

s + 40 + 60 = 180 {angle sum property}

s + 100        = 180

               s = 180 - 100

               s = 80

This figure is a cyclic quadrilateral. sum of opposite angles are 180

s + v + 60 + 10 = 180

80 + v + 60 + 10 = 180

             v + 150  = 180

                       v = 180 - 150

                      v = 30

y+ 10 + v  = 180 {angle sum property}

    y + 10 + 30 = 180

             y + 40 = 180

                   y = 180 - 40

                  y = 140

Answer:

  r = 80°, s = 80°, t = 10°, u = 60°, v = 30°

Step-by-step explanation:

Working clockwise from the left side, we can name the points on the circle as A, B, C, D. The given inscribed angles are half the measure of the arcs they intercept, so we have ...

  arc BD = 2×40° = 80°

  arc DA = 2×60° = 120°

  arc CD = 2×10° = 20°

From these measures, we can deduce the measures of the individual arcs as ...

  arc AB = 360° -BD -DA = 360° -80° -120° = 160°

  arc BC = BD -CD = 80° -20° = 60°

Then the angle measures of interest are ...

  r = AB/2 = 80°

  s = AB/2 = 80°

  t = CD/2 = 10°

  u = DA/2 = 60°

  v = BC/2 = 30°

Answer: $128.00

Step-by-step explanation:

From the question, we are given the information that Ivana's furniture store buys a chair at a wholesale price of $320.00 and that the markup rate at Ivana's store store is 40%.

The total markup will then be:

= Markup rate × Price

= 40% × $320

= 0.4 × $320

= $128.00

Answer:

7x

Step-by-step explanation:

To purchase 7 tickets at the same rate ;

Mathematically, Total Cost of an item is :

Cost = unit price * quantity

Here,

quantity = 7 tickets

Since price per ticket(rate) is the same ; then we can take rate as x

Hence, the cost of the 7 tickets is :

Quantity * rate

7 * x = 7x

Answer:

The slope of the line that contains FG is -1

Step-by-step explanation:

Given

[tex]x -y= 2[/tex] --- equation of EF

Required

Determine the equation of FG

First, we calculate the slope of EF

[tex]x -y= 2[/tex]

Make y the subject

[tex]y = x - 2[/tex]

A linear equation has the form:

[tex]y = mx + b[/tex]

Where

[tex]m = slope[/tex]

By comparison:

[tex]m = 1[/tex]

In square EFGH, EF and FG are perpendicular.

So, the relationship between their slopes is:

[tex]m_2 = -\frac{1}{m_1}[/tex]

Where

[tex]m_1 = m = 1[/tex] --- slope of EF

The equation becomes:

[tex]m_2 = -\frac{1}{1}[/tex]

[tex]m_2 =-1[/tex]

Answer:

t + w + h + v - k = M, where M is the total amount in his account.

Step-by-step explanation:

Thank goodness they're not trying to get you to solve this, hahaha. They just want you to show you started with t, added the next 3 letters, then subtracted one.

Answer:

P(t) = 20,000 * e^0.173287t

Step-by-step explanation:

P(t) = Po * e^k*t

Po = 20,000

t = 4

P(t) = 40,000

40,000 = 20,000 * e^4k

2 = e^4k

ln 2 = ln e^4k

ln 2 = 4k * ln e

ln 2 = 4k

0.173287 = k

Answer: 62 cm = 24 inch

Step-by-step explanation: one inch is 2.54 cm. you divide 62 cm by

2.54 which is also a conversion factor. You calculate 62 cm/ 2.54 = 24.409 inch

Answer:

B) -1/2

Step-by-step explanation:

Slope is change in y divided by change in x.

So, 6-4/-4-0 = 2/-4 so reduces to -1/2

Answer:

Slope = -4

Step-by-step explanation:

Slope = change in y ÷ Change in x

         [tex]= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\= \frac{0-4}{5-4}\\\\= \frac{-4}{1}\\\\= - 4[/tex]

Answer:

x = 5

Step-by-step explanation:

using the Pythagorean theorem:

(x-1)² + (x-2)² = x²

x²-2x+1 + x²-4x+4 = x²

reduce:

2x²-6x+5 = x²

subtract x² from each side:

x²-6x+5 = 0

(x-1)(x-5) = 0

x=1 but because shorter leg would be 0, a triangle would be impossible.

x=5

Answer: 7 tickets

Step-by-step explanation:

First you need to remove the cost of entrance from the $45 that Hayden has:

= 45 - 8

= $37

The $37 is the amount that is left for Hayden to be able to buy tickets for the raffle.

The tickets cost $5 each so the highest number of tickets that can be bought with $37 is:

= 37 / 5

= 7 tickets

Answer:

4.1

Step-by-step explanation:

Length of rectangles = 7 in.

Breadth of 4 rectangles = 3 x 4

                                          = 12 in.

Side of squares = 3 in.

Area of 4 rectangles = length x breadth

                                    = 7 x 12

                              = 84 sq. in.

Area of two squares = 2(side x side)

                                  = 2(3 x 3)

                                  = 18 sq. in.

Therefore, Surface area of the Jewellery box = 84 sq. in. + 18 sq. in.

                                                                              = 102 sq. in.
