Answer:

[tex]38.4\ \text{units of fuel/mile}[/tex]

10

Step-by-step explanation:

Let [tex]N[/tex] represent the number of rail cars on the train

Each rail car adds 2.2 units of fuel per mile.

Fixed fuel consumption is 12 units of fuel per mile

The function of fuel consumption per mile is

[tex]f(N)=12+2.2 N[/tex]

when

[tex]N=12[/tex]

[tex]f(12)=12+2.2\times 12\\\Rightarrow f(12)=38.4\ \text{units/mile}[/tex]

[tex]\boldsymbol{f(12)=38.4\ \text{units/mile}}[/tex]

[tex]f(N)=34\\\Rightarrow 12+2.2N=34\\\Rightarrow N=\dfrac{34-12}{2.2}\\\Rightarrow N=10[/tex]

So, the number of rail cars when [tex]f(N)=34[/tex] is 10.

Answer:

Step-by-step explanation:

One third

The centroid of a triangle divides each median.

The shorter segment is 1/3 and the length of the entire segment is 1

The centroid of a triangle divides the median in the following ratio

[tex]\mathbf{Ratio = 2 : 1}[/tex]

The fraction of the shorter segment is:

[tex]\mathbf{Short = \frac{1}{1 + 2}}[/tex]

[tex]\mathbf{Short = \frac{1}{3}}[/tex]

Hence, the shorter segment is 1/3, while the entire segment is 1.

Answer:

[tex] x = 18 [/tex]

[tex] y = 7.5 [/tex]

[tex] z = 7 [/tex]

Step-by-step explanation:

✍️[tex] (8x - 7) + (3x - 11) = 180 [/tex] (consecutive interior angles are supplementary)

Solve for x

[tex] 8x - 7 + 3x - 11 = 180 [/tex]

Add like terms

[tex] 11x - 18 = 180 [/tex]

Add 18 to both sides

[tex] 11x = 180 + 18 [/tex]

[tex] 11x = 198 [/tex]

Divide both sides by 11

✅[tex] x = 18 [/tex]

✍️[tex] (2y + 23) = (4y + 8) [/tex] (alternate interior angles are congruent)

Solve for y

[tex] 2y + 23 = 4y + 8 [/tex]

Collect like terms

[tex] 23 - 8 = 4y - 2y [/tex]

[tex] 15 = 2y [/tex]

Divide both sides by 2

✅y = 7.5

✍️[tex] (2y + 23) + (3z^2 - 5) = 180 [/tex] (linear pair angles)

Plug in the value of y

[tex] (2(7.5) + 23) + (3z^2 - 5) = 180 [/tex]

[tex] (15 + 23) + (3z^2 - 5) = 180 [/tex]

[tex] 38 + 3z^2 - 5 = 180 [/tex]

Add like terms

[tex] 3z^2 + 33 = 180 [/tex]

Subtract 33 from each side

[tex] 3z^2 = 180 - 33 [/tex]

[tex] 3z^2 = 147 [/tex]

Divide both sides by 3

[tex] z^2 = \frac{147}{3} [/tex]

[tex] z^2 = 49 [/tex]

Square both sides

[tex] \sqrt{z^2} = \sqrt{49} [/tex]

[tex] z = 7 [/tex]

Answer:

yes

Step-by-step explanation:

Each value of x multiplied by 4 gives the corresponding value of y, that is

3 × 4 = 12

5 × 4 = 20

6 × 4 = 24

9 × 4 = 36

Thus x and y are proportional and the constant of proportion is 4

Answer: length=27, width 9

Step-by-step explanation: To solve this problem, you should set up an equation. The length is 3x, and the width is x. To find the perimeter of a triangle, you do length times two + width times two. So 6x+2x=72. 8x=72, x=9. Length is 27, width is 9.

Answer:

Length: 27cm

Width: 9cm

Step-by-step explanation:

Since the length of the rectangle is 3 times the width, we can assume the    width=x and the length=3x.

      P=72cm

     Perimeter= 3x+3x+x+x

Set the 2 equations equal to each other

   72=3x+3x+x+x

Solve for x

   72=8x

   9=x

Length=3x

   Length=9(3)

   Length=27

Width=x

   Width=9

Answer:

Your slope would be 2.

Step-by-step explanation:

To find the slope, you would need to use the formula: y2-y1/x2-x1

In this case, the equation would be 8-(-8)/2-(-6)

8 - (-8) = 16

2 - (-6) = 8

16/8 = 2

The x intercept is (4,0) and the y intercept is (0,-7)

Step-by-step explanation:

Answer:

Step-by-step explanation:

The x-intercept of a line is when the y-coordinate is 0. To find that point on this line, we first want to rearrange the equation into the form

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

we are given

[tex]14x - 8y = 56\\so, \\14x - 56 = 8y\\\frac{14x}{8} - \frac{56}{8} = \frac{8y}{8} \\y = \frac{7}{4}(x) - 7[/tex]

now, we can set y to 0 and solve

[tex]\frac{7}{4}(x) = 7\\7x = 28\\x = 4[/tex]

The x-intercept is (4, 0)

Given that,
Then nth term of a sequence is 10-4n list the first 3 terms​ is to be determined.

Arithmetic progression is the series of numbers that have common differences between adjacent values

Geometric progression is a sequence of series whose ratio with adjacent values remains the same.

Here,
Nth term = 10 - 4n
For the first term, put n = 1
1 st term = 10 - 4 = 6

What is the average of a set of numbers?

An average is a number expressing the central or typical value in a set of data, in particular the mode, median, or (most commonly) the mean, which is calculated by dividing the sum of the values in the set by their number.

Given

September, $28.95;

October, $46.15;

November, $68.46;

December, $109.34;

January, $115.26;

February, $94.19;

March $75.66;

April, $51.97; and

May, $49.16.

Step two:

Total amount= 28.95+46.15+68.46+109.34+115.26+94.19+75.66+51.97+49.16= 639.14

Step-by-step explanation:

I take it that x is somewhere near the end of the diagonal line, so you want to know the value of 3x + 1???

We know that (3x + 1) + (2x + 4) = 90 degrees. That's because AEF = 90 degrees.

So begin by removing the brackets.

3x + 1 + 2x + 4 = 90                 Combine the like terms.

5x + 5 =90                               Subtract 5 from both sides.

5x + 5 - 5 = 90 - 5                   Combine  

5x = 85                                    Divide by 5

x = 17

3x + 1  = 3*17 + 1 = 51 + 1 = 52

Answer:The slope of a line measures the steepness of the line. Most of you are probably familiar with associating slope with "rise over run". Rise means how many units you move up or down from point to point. Run means how far left or right you move from point to point. On the graph, that would mean a change of x values.

Answer:

y = 3.91 when x =7

Step-by-step explanation:

y = k / x⁴

Where,

k = constant of proportionality

y=15 when x=5

y = k / x⁴

15 = k / 5⁴

Cross product

15 × 5⁴ = k

15 × 625 = k

9,375 = k

What is y when x=7?

y = k / x⁴

= 9,375 / 7⁴

= 9,375 / 2401

= 3.9046230737192

[tex]y=-\frac{2}{3}x -5[/tex]

Step-by-step explanation:

Slope-intercept form:

[tex]y=mx+b\\\\y=(slope)x+(y-intercept)[/tex]

When two lines are parallel, their slopes are the same. Take the slope from the given equation and insert into the new:

[tex]y=-\frac{2}{3} x+b[/tex]

Now find the y-intercept. For this, insert the given coordinate points and the slope into the equation to solve for b:

[tex](-6_{x},-1_{y})\\\\-1=-\frac{2}{3} (-6)+b[/tex]

Simplify multiplication using the rule [tex]\frac{a}{b} *c=\frac{ac}{b}[/tex] :

[tex]-1=-\frac{2(-6)}{3} +b\\\\-1=-\frac{-12}{3} +b\\\\-1=\frac{12}{3} +b\\\\-1=4+b[/tex]

Use inverse operations to isolate the variable. Subtract 4 from both sides:

[tex]-1-4=4-4+b\\\\-5=b[/tex]

The y-intercept is -5. Insert:
