The equation for the annual driving cost, C, in terms of d, the number of miles driven is C = 0.125 d + 5000.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

annual cost of driving = $5000 per year

operating costs of car =  12.5 cents per mile = $0.125

Let total distance drive annually be dmile

So, operating costs of car annually  = $0.125 of total distance drive

⇒operating costs of car annually  = $0.125  of d

⇒operating costs of car annually  = $0.125 d

So,  equation for the annual driving cost, C, in terms of d, the number of miles driven is given as,

annual driving cost, C = operating costs of car annually + annual cost of driving

⇒ C = 0.125 d + 5000

Hence,The equation for the annual driving cost, C, in terms of d, the number of miles driven is C = 0.125 d + 5000.

x=3

Step-by-step explanation:

25x+57+x=45x

26x+57=45x

57=19x

x=57/19

x=3

ANSWER

x=96°

EXPLANATION

The sum of exterior angles of a polygon is 360°.

So we add all the exterior angles and equate to 360°

130°+134°+x=360°

264°+x=360°

x=360°-264°

x=96°

5) We want to find the union and the intersection of the given intervals.

The value of the natural logarithm when x = 0.5 is rounded to the nearest hundredth is -0.69. So option B is correct.

When you raise a number with an exponent, there comes a result.

Let's say you get

a^b = c

Then, you can write 'b' in terms of 'a' and 'c' using a logarithm as follows

[tex]b = \log_a(c)[/tex]

'a' is called the base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'

Since x is lesser than 1, then the value of its natural logarithm must be negative.

The natural logarithm is a transcendental function and an irrational number, then it can be estimated by approximations.

ln ( 0.5) = -0.69

The value of the natural logarithm when x = 0.5 is rounded to the nearest hundredth is -0.69. So option B is correct.

We are given the statement [tex] ( a + b ) + c [/tex] and we are to determine whether which of the given answer options allows it to be written as [tex] c + ( a + b ) [/tex].

According to the associative property of addition, you can add the numbers regardless of how they are grouped.

Therefore, (a + b) + c = c + (a + b) is possible with associative property of addition.

The answer is commutative - addition!

The reason it is not associative is because while the direction changes, the parentheses does not move! In the associative, the parenthesis moves, but in (a + b) + c = c + (a + b), the parenthesis contains a + b in both of them. Also here is some picture proof. (Attached)

Step-by-step explanation:

We are trying to find an equation in y=mx+b form

Okay so we know two points on the graph,  from which we can get the slope (value of m) by the formula [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]

plugging in the values:  [tex]\frac{6 -1}{8-9}[/tex]

so their product is 112, so tis just a matter of doing some quick prime factoring and combining the factors about.

The triangle with an area of 56 m² can have the base-height pairs: (1, 112), (2, 56), (4, 28), (7, 16), (8, 14), (14, 8), (16, 7), (28, 4), (56, 2), and (112, 1). These pairs satisfy the equation base × height = 112.

The formula for the area of a triangle is 1/2 × base × height. Given that the area of a triangle is 56 m², we can write this as:

Area = 1/2 × base × height

Rearranging for whole number dimensions, we get:

base × height = 2 × Area

Therefore, base × height = 112 m².

Next, we find all pairs of whole numbers (base, height) whose product is 112:

These are all the possible sets of whole number dimensions for the base and height of the triangle with an area of 56 m².

The expression representing the length of a rectangle could vary depending on context, such as using graph measurements (Δx = 41 m), significant figures (1.25 cm), or scaling factors (4 inches × 2 = 8 inches).

To determine the expression that represents the length of a rectangle, we generally use the formula for the perimeter or area, depending on what information is available. In this case, information provided suggests different scenarios involving measurements and area calculations. From one scenario, the length of a rectangle is calculated using graph paper measurements, resulting in Δx = 41 m. In another scenario, we're given information about a rectangle's width being 1.25 cm with three significant figures.

In physics-related contexts, references to frame of reference and speed c suggest considering displacement in spacetime, though this might not relate directly to the geometrical dimensions of a rectangle. Lastly, one mention involves the scaling up by a factor, such as a square with side length doubled, resulting in a side length expression of 4 inches × 2 = 8 inches. Without further context, it is not possible to provide a definitive expression for the length of a rectangle.

Answer:

The solution to this system is (4, 1/6).

Step-by-step explanation:

Please separate these two equations for clarity.  I like to write them in column format:

2.5y + 3x = 27

5x – 2.5y = 5

---------------------

8x           = 32, and x = 4.

Subbing 4 for x in the second equation yields 5(4) - 2.5y = 5.

Then 20 - 2.5y = 5, or 15 = 2.5y.  Solving for y, we get y = 1/6.

The solution to this system is thus (4, 1/6).

Answer: The resultof adding the two equations is 3x= 32.  

The solution to the system is ( 4; 6).

Step-by-step explanation:

Hi, first we add the two equations.

2.5y + 3x =27

+

-2.5y +5x   = 5

----------------------

8x= 32

The resultof adding the two equations is 3x= 32

the next step is solving the equation:

8x= 32

x=32/8

x= 4

Substituting the value of x in any of the original equations:

2.5y +3x= 27

2.5y +3(4) =27

2.5y +12=27

2.5y  = 27-12

2.5y = 15

y= 15/2.5

y=6

So, the solution to the system is ( 4; 6)

Answer: C, the mean is most likely about 28 lbs.

Step-by-step explanation: The mean of a data set is the average value. When looking at this histogram, you can determine how many bags were checked in  total by adding up the frequencies for each weight.

Add the Weights

1+16(4)+20(5)+24(6)+28(5)+32(4)+36(3)+40+48+52+56+60

**16(4)=64. The number in parenthesis represents how many times each weight occurred in the data set. To make it easier, you can combine some of these instead of typing the extended equation into your calculator.

12+64+100+144+140+128+108+208= 904

Solve for the Mean

To do this, divide 904 by the number of bags checked (32).

Mean: 28.25

**The answer is MORE than 28, but it would round down because the decimal is less than half.

Hope this helps,

Answer:

a. 9.5x + 6.5(x+c) < 8   when c>0

b. Must be one child more than the no. of adults.

Step-by-step explanation:

For Cinema 1:

for adult = $9.50

for child = $6.50

For Cinema 2:

Per person regardless of age = $8.00

First of all, we will find out the condition when per person rates in both cinema are equal.

Assume x = no. of adults

y = no. of children

Rate per person in Cinema I = Rate per person in Cinema II

(9.5x + 6.5y)/(x+y)   =   8

9.5x + 6.5y = 8(x+y)

9.5x + 6.5y = 8x + 8y

9.5x-8x = 8y-6.5y

=> x = y

So rates are equal when no. of adults equals no. of children

For Cinema I to have better rates, no. of children should be atleast 1 more than the no. of adult. In this way the rate per person of Cinema I will be less than 8

Hence we form an inequality when y = x+c and c > 0

9.5x + 6.5(x+c) < 8   when c>0

Hence there must be 1 more children than the no. of adults attending Cinema I for it to be a better deal.

Answer:

9.50a+6.50c < 8.00(a+c), 6 children

Step-by-step explanation:

Let the number of adults be a

the number of children be c

Part 1 :

Cinema 1:

Cost for adults = $9.50 x a = 9.50a

Cost of children = $6.50 x c = 6.50c

Total cost = 9.50a+6.50c

Cinema 2 :

Total cost = 8.00(a+c)

The inequality which shows that the cinema I is cheaper

9.50a+6.50c < 8.00(a+c)

9.50a+6.5c<8a+8c

9.5a-8a<8c-6.5c

1.5a<1.5c

a<c

Case 2:

6 adults goes to cinema , let they are accompanied by c number of children

Cinema 1

Total cost = 9.5 x 6 + 6.5 x c

for cinema 2 the total cost will be

8 ( 6+c)

for cinema 1 to be a better deal

9.5 x 6 + 6.5 x c  < 8(6+c)

57+6.5c<48+8c

57-48<8c-6.5c

9<1.5c

c>6

Hence for Cinema 1 to be a better deal , there must be 6 children accompanying them

Answer:

(6,-2)

Step-by-step explanation:

2x + 3y = 6

 x + y = 4

Multiply the second equation by -2 to eliminate x

-2(x+y) = -2*4

-2x-2y = -8

Add this to the first equation

2x + 3y = 6

-2x -2y = -8

---------------------

       y = -2

Now we need to find x

x+y = 4

x-2 = 4

Add 2 to each side

x-2+2 = 4+2

x = 6

(6,-2)

Answer:

(6,-2)

Step-by-step explanation:

Given equations are [tex]2x + 3y = 6[/tex] and [tex]x + y = 4[/tex].

Solve 2nd equation  [tex]x + y = 4[/tex] for y

[tex]x + y = 4[/tex]

[tex]y = 4-x[/tex] ...(i)

Plug value of y from equation (i) into first equation  [tex]2x + 3y = 6[/tex]

[tex]2x + 3(4-x) = 6[/tex]

[tex]2x + 12-3x = 6[/tex]

[tex]12-x = 6[/tex]

[tex]-x = 6-12[/tex]

[tex]-x = -6[/tex]

[tex]x = 6[/tex]

Plug x=6 into equation (i)

[tex]y = 4-x[/tex]

[tex]y = 4-6[/tex]

[tex]y = -2[/tex]

Hence final answer is x=6, y=-2 or we can write that in (x,y) form as (6,-2)

Answer:

option C 290.5 units^2 is correct.

Step-by-step explanation:

To solve the equation (j)/5 + 1 = -4, subtract 1 from both sides and then multiply by 5 to isolate j, which gives the solution j = -25.

To solve the equation (j)/5 + 1 = -4, you must first isolate the variable, j. Begin by subtracting 1 from both sides of the equation.

(j)/5 + 1 - 1 = -4 - 1

(j)/5 = -5

Next, multiply both sides by 5 to solve for j:

5 * (j)/5 = -5 * 5

j = -25

Therefore, the solution to the equation is j = -25.

Remember to always check your solution by substituting it back into the original equation to ensure it makes sense.

Answer:

Hence final answer is [tex]x<-8[/tex] or [tex]x>\frac{1}{5}[/tex]

correct choice is B because both ends are open circles.

Step-by-step explanation:

Given inequality is [tex]\frac{x+8}{5x-1}>0[/tex]

Setting both numerator and denominator =0 gives:

x+8=0,  5x-1=0

or x=-8, 5x=1

or x=-8, x=1/5

Using these critical points, we can divide number line into three sets:

[tex](-\infty,-8)[/tex], [tex]\left(-8,\frac{1}{5}\right)[/tex] and [tex](\frac{1}{5},\infty)[/tex]

We pick one number from each interval and plug into original inequality to see if that number satisfies the inequality or not.

Test for [tex](-\infty,-8)[/tex].

Clearly x=-9 belongs to [tex](-\infty,-8)[/tex] interval then plug x=-9 into [tex]\frac{x+8}{5x-1}>0[/tex]

[tex]\frac{-9+8}{5(-9)-1}>0[/tex]

[tex]\frac{-1}{-46}>0[/tex]

[tex]\frac{1}{46}>0[/tex]

Which is TRUE.

Hence [tex](-\infty,-8)[/tex] belongs to the answer.

Similarly testing other intervals, we get that only [tex](-\infty,-8)[/tex] and [tex](\frac{1}{5},\infty)[/tex] satisfies the original inequality.

Hence final answer is [tex]x<-8[/tex] or [tex]x>\frac{1}{5}[/tex]

correct choice is B because both ends are open circles.

Answer:

[tex]x \:<\:-8[/tex] or  [tex]x \:>\:\frac{1}{5}[/tex].

Step-by-step explanation:

The given inequality is [tex]\frac{x+8}{5x-1} \:>\:0[/tex]

For this statement to be true, then we must have the following cases:

Case 1

[tex]x+8 \:<\:0\:and\:5x-1\:<\:0[/tex]

[tex]x \:<\:-8\:and\:x\:<\:\frac{1}{5}[/tex]

The intersection of these two inequalities is [tex]x \:<\:-8[/tex].

The solution to this first case is  [tex]x \:<\:-8[/tex].

Case 2

[tex]x+8 \:>\:0\:and\:5x-1\:>\:0[/tex]

[tex]x \:>\:-8\:and\:x\:>\:\frac{1}{5}[/tex]

The intersection of these two inequalities is [tex]x \:>\:\frac{1}{5}[/tex].

The solution to this second case is  [tex]x \:>\:\frac{1}{5}[/tex].

Therefore the solution to the given inequality is

[tex]x \:<\:-8[/tex] or  [tex]x \:>\:\frac{1}{5}[/tex].

The necessary conditions are: B. Opposite sides are parallel, A. Alternate interior angles, and D. Alternate interior angles are supplementary.

To prove that the opposite sides of a parallelogram are congruent, the following conditions are necessary:

1. **Opposite sides are parallel (Option B)**: This is a fundamental property of parallelograms. Parallel sides ensure that corresponding angles are congruent and alternate interior angles are congruent.

2. **Alternate interior angles (Option A)**: If the opposite sides are parallel, then alternate interior angles will be congruent. This property is essential in establishing the equality of corresponding sides.

3. **Alternate interior angles are supplementary (Option D)**: This property is crucial in proving the congruence of opposite sides. It guarantees that when opposite angles are equal, the opposite sides will also be equal.

Therefore, the correct options are A, B, and D. These conditions collectively ensure the congruence of opposite sides in a parallelogram.
