9514 1404 393

Answer:

  $350

Step-by-step explanation:

Let c represent the cost in 2003. Then we have the cost in 2004 is ...

  c + 0.10·c = 385

  1.1c = 385

  c = 385/1.1 = 350

The cost in 2003 was $350.

Answer:

10, 20,30, 40, 50

Step-by-step explanation:

You times them all by 10 for example: 1x10=10 2x10=20 3x10= 30 4x10=40 and 5x10=50.

If we buy four packs of hot dogs and five packs of buns then we don't have any left over.

The abbreviation LCM stands for "Least Common Multiple." The smallest multiple that two or more numbers share is known as the least common multiple.

For example: Take two integers, 2 and 3.

Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20….

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 ….

Therefore, 6 is the least common multiple of 2 and 3.

Given:

Packs          1       2     3      4       5

Hot Dogs   10     20   30   40    50

Bun             8      16     24   32    40

Also, LCM(10, 8)

10= 2 x 5

8= 2 x 2 x 2

So, LCM(10, 8)= 2 x 2 x 2 x 5 = 40

Hence, If we buy four packs of hot dogs and five packs of buns then we don't have any left over.

Answer: 86 degree

Step-by-step explanation:

The Straight line is 180 degrees so if we minus 180 by the outward degree there will be the degree for inward degree

P: 95 degrees T: 160 degree S: 88 degrees R: 91 degree

The degree for the pentagon is 540 degrees so If I minus 540 by all the four inward degrees there will be the missing last degree

95 + 160 + 88 + 91 = 434 degree

540 - 434 = 106 degree

180 - 106 = 94 degree

So the last inward degree is 94

Finally, if I minus 180 by 94 (the way I used to find inward degree and to find outward degree for now) it equals 86 degree

so X is 86 degree

Sorry if this was too confusing:)

Answer:

1st--> x=135

2nd-->x=74

Step-by-step explanation:

1st:

triangle =180°

180-90=90

90÷2=45

straight line=180°

180-45=135

therefore x=135°

2nd:

pentagon=540°

straight line=180°

180-92=88 for line s

180-20=160 for line q

180-85=95 for line p

180-89=91 for line r

160+95+88+91=434

540-434=106

180-106=74

therefore x=74°

48 x 10 = 480

48 x 4 = 192

480 + 192 = 672

139 x 10 = 1390

139 x 2 = 272

1390 + 272 = 1662

1662 + 672 = 2334

Answer:

y = 10/9x + 9

Step-by-step explanation:

To write the equation in its slope-intercept form, y = mx + b, we need to find the slope (m) of the line and its y-intercept (b).

Given the points (0, 9) and (9, 19), we can solve for the slope of the line using the following formula:

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

Let (x1, y1) = (0, 9)

and (x2, y2) = (9, 19)

Substitute these values on the formula:

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{19 - 9}{9 - 0} = \frac{10}{9}[/tex]

Therefore, the slope (m ) = 10/9.

Next, the y-intercept is the point on the graph where it crosses the y-axis, and has the coordinates, (0, b ). It is also the value of the y when x = 0.

One of the given points is the y-intercept of the line, given by (0, 9). The y-coordinate, 9, is the value of b.

Therefore, the linear equation in slope-intercept form is: y = 10/9x + 9

91,731 would be the greatest number since it has the largest number in the ten-thousands place.

Answer:

Mean 5.3, Median 6, Mode 6, Range 7

Step-by-step explanation:

First we arrange the numbers from smallest to the largest. (When you are done count them to see if you have the same amount of numbers that you had before you arrange them.)

1, 3, 5, 6, 6, 6, 7, 8

Mean: is the average of all the numbers :add all numbers / how many numbers we have

(1+ 3+ 5+ 6+ 6+ 6+ 7+ 8) /8 = 42/8 = 5.25 ≈5.3 (rounded to the nearest tenth)

Median: is average of the 2 numbers that are in the middle 1, 3, 5, 6, 6, 6, 7, 8

(6+6)/2 = 6

Mode: is the number that appears the most so is 6

1, 3, 5, 6, 6, 6, 7, 8

Range: is the difference between the highest and the lowest value

1, 3, 5, 6, 6, 6, 7, 8

8-1 = 7

Answer:

Mean- 42

Median- 6

Answer:

Change ≈ 284.6154%

Step-by-step explanation:

To calculate the percent change of two numbers such as 450 to 117, you use the Percent Change Formula, where a is the start value and b is the end value.

(b-a)/a x 100

When we insert a = 450 and b = 117 in the formula above, then we get the following that we can simplify and solve to get the percent change from 450 to 117.

(117-45)/450 x 100

-333/450 x 100

Change = -74%

Now you know that the percentage change from 450 to 117 is -74%. Since it is a negative answer, it means that if you subtract 74% from 450, then you will get 117.

Answer:

First number line: 3rd line from 0

Second number line: 7th line from 0

(Sorry if I explained it kinda weird, hope this helps!)

Step-by-step explanation:

On the first number line, you would put the dot on the 3rd line from zero. From 0 to one, it's split into 5 equal parts. 0 is 0/5 and 1 is 5/5. So all you do is  plot the dot on 3/5, or the 3rd line from 0.

Same thing with the second number line. Except for this time, it's split into 8 equal parts. Just count to the 7th line in between 0 and 1 and plot the dot.

Step-by-step explanation:

Answer:

9 + (-7) = 2

Step-by-step explanation:

Answer: 2/5

Explanation: Ask if you want an explanation!

      The question gives us two points, (-2, 1) and (8,5), from which we can find the slope and later the equation of the line.

Finding the Slope

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)      

                                          =  (5 - 1) ÷ (8 - (-2))    

                                          =   ⁴/₁₀

                                          = ²/₅  

Checking my answer:

We can check to see if the answer is correct by drawing the line and seeing if it passes through both points. If it does, then the slope is correct.

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:

                                ⇒  y - 1 =  ²/₅ (x + 2)

In the graph below (created using Desmos), the line passes through both points. This suggests that we calculated the slope correctly.

x = 36
