Answer 1

Answer:

Length --> x

Width --> y

Perimeter of a rectangle --> 2x + 2y

The length is always 4 cm more than double the width

x - 4 = 2y

y = (x-4)/2

x = 2y + 4

a. The polynomial equation to give the perimeter --> 2(2y+4) + 2((x-4)/2)

b. x - 4 = 2·6 --> x - 4 = 12 --> x = 16

  Perimeter --> 2·16 + 2·6 = 44 cm

trey had 440 songs on his mp3 player.now he has 473 songs.what is the percent of increase in the number of songs on his mp3 player?
round to the nearest tenth if necessary.

Answers

Answer:

There is 7.5% increase in the number of songs on his mp3 player.

Step-by-step explanation:

Original Songs in mp3= 440 songs

Final Songs in mp3= 473 songs

We need to find percent of increase in the number of songs on his mp3 player.

The formula used is: [tex]Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100[/tex]

Now putting values and finding percent of increase

[tex]Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100\\Percent \ of \ increase = \frac{473-440}{440} \times 100\\Percent \ of \ increase = 7.5\%[/tex]

So, there is 7.5% increase in the number of songs on his mp3 player.

I need help with solving for x. Then find the measure of the base angle. Please

Answers

Answer:

x = 8 base angle = 81 degrees

Step-by-step explanation:

Answer:

x = 8

base angle = 81 deg

Step-by-step explanation:

we observe that because the given triangle is a isosceles triangle, the base angles must be the same.

Hence the missing base angle must also be (10x+1)°

recall that all internal angles of an triangle must add up to 180 deg,

hence

180° = sum of all internal angles

180° = 18° + (10x+1)° + (10x+1)°

180° = 18° + 2(10x+1)°    (subtracting 18 from both sides)

180 - 18 = 2(10x+1)

162 = 2(10x+1)   dividing both sides by 2)

162 / 2 = 10x + 1

81 = 10x + 1    (subtracting 1 from both sides)

81 - 1 = 10x

10x = 80   (divide both sides by 10)

x = 80/10

x = 8   (answer)

substituting x = 8 into the expression for the base angle

base angle = (10x+1)

= 10(8) + 1

= 10 + 1

= 81

Answers

Answer:

3

Step-by-step explanation:

combine like terms (so 1/2 and 3/2): 2 - x = x - 4

add x to both sides: 2 = 2x - 4

add 4 to both sides: 6 = 2x

divide both sides by 2: 3 = x

a 6 ounce package costs $2.10 a 16 ounce package costs $5.28 a 26 ounce package costs $9.36 which package is the best buy

Answers

Answer:

The better buy is the 16 ounce package for $5.28.

Step-by-step explanation:

First divide each price with their ounce,so 2.10 ÷ 6 = 2.1 per 1 ounce , 5.28 ÷ 16 = 0.33 per 1 ounce , 9.35 ÷ 26 = 0.36 per 1 ounce.

Next compare the prices for 1 ounce and see which on is lower. The 16 ounce package has a better price because the price for each ounce is lower than the other prices.

4. Line r is mapped onto line m by a dilation centered at the origin with a
scale factor of 4. The equation of line r is 6x – 3y = 12. What is the
equation for line m?

Answers

3x - y = 8

Step-by-step explanation:

Since, if a line having points represented by (x,y) is dilated about origin with a scale factor k,

Then the coordinates of the dilated line is obtained by the rule,

Here, line L is,

3x - y = 4

The x-intercept and y-intercept of line L are (4/3,0) and (0,-4) respectively,

If the line L is mapped onto line M by a dilation centered at the origin with a scale factor of 2,

Then by the above definition,

The points of the line M are,

(2×4/3, 2×0) and (2×0, 2×-4) ⇒ (8/3,0) and (0,-8)

Hence, the equation of line M passes through the points (8/3,0) and (0,-8)

Tom, Sam and Victor are painting the rooms in their new house. It takes Tom 4 hours to paint one room, but Sam and Victor take 3 hours each. If all of them work together, how long does it take them to paint one room?

Answers

9514 1404 393

Answer:

  12/11 = 1 1/11 hours

Step-by-step explanation:

The total rate is the sum of the individual rates in rooms per hour.

Tom can paint 1/4 room per hour.

Sam and Victor can each paint 1/3 room per hour.

Their total rate is ...

  1/4 +1/3 +1/3 = 11/12 . . . rooms per hour

The rate in "hours per room" is the inverse of this.

It takes them 12/11 = 1 1/11 hours to paint one room.

Answers

Answer:

a = 150

Step-by-step explanation:

The sum of the internal angles of an octagon is 1080°.

[tex]4a+4(120)=1080[/tex] (There are four [tex]120^{\circ}[/tex] and 4 [tex]a^{\circ}[/tex], they sum to 1080°)

[tex]4a + 480 = 1080[/tex]

[tex]4a = 600[/tex]

[tex]a = 150[/tex]

Hope this helps :)

Answer:

a = 150

Step-by-step explanation:

A octagon is 1080 degrees. The half circles are showing which angles are the same. So all the red circles are 120 degrees. To find the green circles, multiply 120 by 4 for the total of the four angles and then subtract it from 1080:

120(4) = 480

1080 - 480 = 600

So 600 is the total of all the green half circles added together, so divide 600 with 4 because there are four green half circles.

600/4 = 150
