To manufacture an automobile requires​ painting, drying, and polishing. Epsilon Motor Company produces three types of​ cars, the​ Delta, the​ Beta, and the Sigma. Each Delta requires 11 hours for​ painting, 5 hours for​ drying, and 3 hours for polishing. A Beta requires 17 hours for​ painting, 8 hours for​ drying, and 4 hours for​ polishing, and a Sigma requires 4 hours for​ painting, 5 hours for​ drying, and 1 hour for polishing. If the company has 253 hours for​ painting, 149 hours for​ drying, and 63 hours for polishing per​ month, how many of each type of car are​ produced?

Answer:

15

Step-by-step explanation:

x(x + 2) = 27 + 6(x + x + 2)

x^2 + 2x = 27 + 6(2x + 2)

x^2 + 2x = 27 + 12x + 12

x^2 + 2x - 12x - 12 - 27 = 0

x^2 -10x - 39 = 0

(x + 3)(x - 13) = 0

x + 3 = 0

x = -3 (extraneous solution)

x - 13 = 0

x = 13

x + 2 = 15

The solution of the geometric system is (x, AB, BC, AC) = (10, 14, 19, 33).

In accordance with geometry, three points are collinear if and only if these points lie on the same line. Then, the geometric system is represented by the following model:

AC = AB + BC

If we know that AB = x + 4, BC = 2 · x - 1 and AC = 4 · x - 7, then the value of x and the lengths of the line segments are, respectively:

4 · x - 7 = (x + 4) + (2 · x - 1)

4 · x - 7 = 3 · x + 3

x = 10

AB = 10 + 4

AB = 14

BC = 2 · 10 - 1

BC = 20 - 1

BC = 19

AC = 4 · 10 - 7

AC = 40 - 7

AC = 33

The solution of the geometric system is (x, AB, BC, AC) = (10, 14, 19, 33).

Based on the number of days that the health inspector and the fire inspector visits, the table for their next 4 visits is:

Number of visits        Health Inspector visits           Fire inspector visits

          1                                             7                                          12

           4                                            28                                       48

The number of days till both inspectors visit on the same day is 84 days.

The model that would be best to use and solve the problem of the number of days till both inspectors visit is the Lowest Common Multiple.

This shows the number of days till both inspectors would visit based on their visiting interval.

The lowest common multiple of 7 and 12 is 84 which means that the health and fire inspectors would visit after 84 days on the same day.

Using angle sum property for angles For, the given triangle, the value of x = 23°

The angle sum feature is a characteristic shared by all varieties of triangles. Triangles have an angle sum property of 180 degrees. This indicates that a triangle's internal angles add up to 180 degrees.

The angle 135 ,makes a linear pair with the line

So, the angle will be -

180 - 135

= 45°

Using angle - sum property,

x + 45 + 112 = 180

x + 157 = 180

x = 180 - 157

x = 23

Choose to use same variables next time to avoid confusions!!!!.

Answer:

b) -8

c) 11

d) {x is a member of all real numbers | except for 2}

Answer:

(a) Choice C is correct

(b) f(x) = -8  Point is (1, -8)

(c) x =11  Point is at (11,2)

(d) Domain of f is x is [tex]\:x < 2\quad \mathrm{or}\quad \:x > 2\:[/tex]  
    In interval notation [tex]\:\left(-\infty \:,\:2\right)\cup \left(2,\:\infty \:\right)[/tex]

(e)  x intercept is at x = -7

(f) y-intercept is at [tex]-\frac{7}{2} = -3.5[/tex]

Step-by-step explanation:

(b) Plug in x = 1 into the equation [tex]\:\:\frac{x+7}{x-2} = \frac{1+7}{1-2} = \frac{8}{-1} = -8[/tex]

(c) If f(x) = 2 then we get [tex]2 = \:\:\frac{x+7}{x-2}[/tex]  

==> 2(x-2) = x + 7

==>   2x - 4 = x + 7

==> 2x - x = 7 +4 =11

==>  x = 11

(d) Domain of f is all values of x -∞ < x < ∞ except at x = 2 since at x = 2 the denominator is 0 and division by zero is undefined; So we can say the domain is x < 2 or x  >2

(e) To get the x-intercept set y = 0 and solve for x
We get (x+7)/(x-2) = 0

x+7 = (x-2)(0) = 0

x = -7 and the x intercept is at point (-7, 0)

(f) [tex]y\mathrm{-intercept\:is\:the\:point\:on\:the\:graph\:where\:}x=0[/tex]

Substitute for x = 0 to get y = (0+7)/(0-2) = -7/2

Step-by-step explanation:

Rounding to the nearest hundredth means the rounding of any decimal number to its nearest hundredth value. In decimal, hundredth means 1/100 or 0.01. For example, the rounding of 2.167 to its nearest hundredth is 2.17.

You didn't show her answer so I don't know her mistake, but you round to the nearest hundredth by looking at the ten's value, if it's a 5 or greater, add one to the hundredths digit. If its lesser than five, leave the hundredth place.

Ex. Rounding 1,567. Because the tens digit is a 6, you round the 5 up to a 6 and get rid of the tens and one digit. 1,567 rounds to 1,600

Ex. Rounding 1,445. Because the tens digit is a 4, you leave the hundredths digit and get rid of the rest. 1,445 rounds to 1,400.

Given the length of the perpendicular height and base length, the hypotenuse of the right triangle is 2√74 ft.

Hence option a)2√74 ft is the correct answer.

The Pythagoras theorem can be expressed as;

c = √( a² + b² )

Where c is hypotenuse, a and b are the other two sides of the right triangle.

Given the data in the image;

Plug the given values into the above equation and solve for the hypotenuse 'c'.

c = √( a² + b² )

c = √( (14)² + (10)² )

c = √( 196 + 100 )

c = √( 296 )

296 can be written as 4 × 74, and 4 can further be written as 2²

Hence

c = √( 2² × 74 )

c = 2√74 ft

Given the length of the perpendicular height and base length, the hypotenuse of the right triangle is 2√74 ft.

What is quarts?

The quart is an English volume unit equivalent to one-quarter gallon. There are now three types of quarts in use: the liquid quart and dry quart of the US customary system, as well as the imperial quart of the British imperial system. All of them are essentially equivalent to one liter. It is split into two pints or four cups (in the United States). The exact size of the quart has historically fluctuated with the varying values of gallons over time and in relation to different commodities.

1 US gallon = 4 US quarts

so, 15 US gallons = 15 x 4 = 60 quarts

The roots of the function are when f(x) = 0:

Case 1

[tex]\begin{aligned}\left(\log(3x)-2 \log(3)\right) & = 0\\\log(3x) & = 2 \log(3)\\ \log(3x) & = \log (3)^2\\ \log(3x) & = \log (9)\\ 3x & = 9\\ x & = 3\end{aligned}[/tex]

Case 2

[tex]\begin{aligned}\left x^2-1\right & = 0\\x^2 & = 1\\ x & = \pm 1\end{aligned}[/tex]
