Answer:

[tex] \boxed{ \bold{ \sf{x = 25°}}}[/tex]

[tex] \boxed{ \bold{ \sf{(x + 5) = 30°}}}[/tex]

[tex] \boxed{ \bold{ \sf{5x = 125°}}}[/tex]

Step-by-step explanation:

We know that sum of angle of triangle adds up to 180°

Finding the value of x

[tex] \sf{5x + x + x + 5 = 180°}[/tex]

Collect like terms

⇒[tex] \sf{7x + 5 = 180}[/tex]

Move 5 to right hand side and change its sign

⇒[tex] \sf{7x = 180 - 5}[/tex]

Subtract 5 from 180

⇒[tex] \sf{7x = 175}[/tex]

Divide both sides of the equation by 7

⇒[tex] \sf{ \frac{7x}{7} = \frac{175}{7} }[/tex]

Calculate

⇒[tex] \sf{x = 25°}[/tex]

Finding the value of ( x + 5 )°

[tex] \sf{x + 5}[/tex]

plug the value of x

⇒[tex] \sf{25 + 5}[/tex]

Add the numbers

⇒[tex] \sf{30°}[/tex]

Finding the value of 5x

[tex] \sf{5 \times 25}[/tex]

Multiply the numbers

⇒[tex] \sf{125°}[/tex]

Answer:

x° = 25°

(x + 5)° = 30°

5x° = 125°

Step-by-step explanation:

total angle inside the triangle = 180 = x + (x+5) + 5x

180 = x + x + 5 + 5x

group like terms

7x + 5 = 180

subtract 5 each sides

7x = 175

x = 175/7

x = 25°

solve for : (x + 5)°

(x + 5)° = 25 + 5

(x + 5)° = 30°

solve for 5x°

5x° = 5 * 25

5x° = 125

check

180 = x + (x+5) + 5x

180 = 25 + (25+5) + (5*25)

180 = 25 + 30 + 125

180 = 180

Answer:

R''(2,-3), S''(-2,-1) and T'(-1,-5).

Step-by-step explanation:

The given vertices of triangle are R(2, 3), S(-2, 1), and T(-1, 5).

Reflection over the y-axis:

[tex](x,y)\to (-x,y)[/tex]

Using this rule, the vertices after reflection are

[tex]R(2,3)\to R'(-2,3)[/tex]

[tex]S(-2,1)\to S'(2,1)[/tex]

[tex]T(-1,5)\to T'(1,5)[/tex]

Rotation at 180 degrees around the origin.

[tex](x,y)\to (-x,-y)[/tex]

Using this rule, the vertices after reflection are

[tex]R'(-2,3)\to R''(2,-3)[/tex]

[tex]S'(2,1)\to S''(-2,-1)[/tex]

[tex]T'(1,5)\to T''(-1,-5)[/tex]

Therefore, the coordinates of vertices after the two transformations are R''(2,-3), S''(-2,-1) and T'(-1,-5).

Answer:

No it's not equal

Step-by-step explanation:

Answer:

The events are  independent.Their conditional probability is equal to the  probability of an event .

2) The probability that there is line spoilage given that there is transformer spoilage=0.08

- Transformer spoilage but not line spoilage=0.046

Transformer spoilage given that there is no line spoilage = 0.05

- Neither transformer spoilage nor there is no line spoilage =0.03

v- Either transformer spoilage or there is no line spoilage  = 0.97

Step-by-step explanation:

Let A be an event that the spoilage is due to transformers so

P(A) = 5% = 5/100 or 0.05

Let B be an event that the spoilage is due to line so

P(B) = 8% = 8/100 or 0.08

Let C be an event that the spoilage is due to both then

P(C) = 3% = 3/100 or 0.03

1)  Independence

For events to be independent their joint probability is given by

P(A) = P(A∩B)/ P (B)  By Law of independence

P(A∩B)= P(A/B)P(B)

P(A∩B) = 5/100 *8/100=40/10000= 4/1000

P(A) = 5/100  

P(A/B) =P(A∩B)/ P (B)

= 4/1000/8/100= 1/20  

P(A)= P(A/B)

5/100 is equal to  1/20

The events are independent.Their conditional probability is equal to the probability of an event

2) The probability that there is line spoilage given that there is transformer spoilage

P(B/A)= P(A∩B)/ P (A) = 4/1000/5/100= 4/50= 2/25=0.08

Which is again equal to probability of event B.

- Transformer spoilage but not line spoilage

P(A∩1-B)= 5/100*92/100= 460/10000=0.046

Transformer spoilage given that there is no line spoilage

P(A/1-B) =P(A∩1-B)/ P (1-B)

= 5/100*92/100/92/100= 5/100 = 0.05

- Neither transformer spoilage nor there is no line spoilage

1-P(A) +P(1-B)= 1-(5/100+92/100)= 3/100= 0.03

v- Either transformer spoilage or there is no line spoilage  

P(A)+P(1-B)= 5/100+92/100= 97/100= 0.97

Answer:

  see below

Step-by-step explanation:

See the attachment.

The graph will have x-intercepts where the factors are zero, at x=6 and x=-2. The y-intercept will be the value when x=0: (1/8)(-6)(2) = -1.5.

The axis of symmetry is halfway between the zeros, so is x = (6-2)/2 = 2.

The minimum value of the function is at x=2, so is ...

  y = (1/8)(2 -6)(2 +2) = 1/8(-16) = -2

Other y-values can be found by substituting other x-values in the equation and evaluating it. Rather than go to that trouble, I prefer to use a graphing calculator.

The answer is 0.73 because in 0.975 the value of digit 7 is 7/100 ,10 times of 7/100 is  7/10 and the value of 7 in 0.73 is 7/10 ;.tenth value.

The value of each digit in a number is known as the place value. The number is 0.73. The correct option is C.

The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.

Identification of the place value of a digit in a number:

The value of digit 7 in the number 0.975 is hundredth. Therefore, the digit 7 in the number 0.975 is equal to 7/100.

Now, if the number is 10 times as great as digit 7 in 0.975. Therefore,

7/100 x 10 = 7/10 = 0.7

Thus, the number in which digit 7 have a value that is 10 times as great as the digit 7 in the number 0.975 is the number that is at the first place after the decimal.

Hence, the number is 0.73.

It is proven that "the sum of the squares of four consecutive integers is an even integer" is the solution part.

To prove that the sum of the squares of four consecutive integers is an even integer, we need to show that it can be expressed as twice another integer.

Let's assume the four consecutive integers are n, n+1, n+2, and n+3.

The sum of their squares can be expressed as:

[tex]n^2 + (n+1)^2 + (n+2)^2 + (n+3)^2[/tex]

Expanding the squares, we have:

[tex]n^2 + (n^2 + 2n + 1) + (n^2 + 4n + 4) + (n^2 + 6n + 9)[/tex]

Combining like terms, we simplify this expression to:

[tex]4n^2 + 12n + 14[/tex]

Now, let's consider this expression [tex]4n^2 + 12n + 14[/tex].

We can factor out 2 from each term, resulting in:

[tex]2(2n^2 + 6n + 7)[/tex]

Since [tex]2n^2 + 6n + 7[/tex] is an integer, let's denote it as k, where k is an integer.

Therefore, the expression becomes:

2k.

We have successfully expressed the sum of the squares of four consecutive integers as twice another integer (2k), which proves that it is an even integer.

Hence, the sum of the squares of four consecutive integers is an even integer.

Answer:

y = -5x - 29

Step-by-step explanation:

y-intercept form is y = mx +b,

m is slope, for parallel line slope is the same, so m= -5

y = -5x + b

To find b, we need to use the point (-5, - 4).

- 4 = -5*(-5) + b

- 4 = 25 + b

b = - 29

y = -5x - 29

Answer:

2 eurocent per kilo

Step-by-step explanation:

Since we are already given the conversion units, we only simply need to divide/multiply and cancel out units.

Dollars and dollars cancel out.

We are left with eurocent.

Pounds and pounds cancel out.

We are left with kilograms.

We do want eurocent over kilograms.

0.89(0.93) = 0.8277/0.4536 = 1.82474

Since we want to round it to the nearest cent, we round up because 8 ≥ 5:

1.82474 ≈ 2

Answer:

Step-by-step explanation:

Given the limit of a function expressed as [tex]\lim_{x \to 1} (\dfrac{3x}{x-1} - \dfrac{3}{lnx})[/tex], we are to evaluate it. To evaluate it, we will simply substitute x = 1 into the function since the variable x tends to 1.

[tex]\lim_{x \to 1} (\dfrac{3x}{x-1} - \dfrac{3}{lnx})\\\\= (\dfrac{3(1)}{1-1} - \dfrac{3}{ln1})\\\\= \dfrac{3}{0} - \dfrac{3}{0}\\\\= \infty - \infty (ind)[/tex]

Since we got an indeterminate function, we will find the LCM of the function and solve again.

[tex]= \lim_{x \to 1} (\dfrac{3x}{x-1} - \dfrac{3}{lnx})\\\\= \lim_{x \to 1} \dfrac{3xlnx-3(x-1)}{(x-1)lnx}\\\\\\= \dfrac{3(1)ln(1)-3(1-1)}{(1-1)ln1}\\\\= \frac{3(0)-3(0)}{0(0)} \\\\= \frac{0}{0} (ind)[/tex]

Applying L'hospital rule;

[tex]\frac{x}{y} = \lim_{x \to 1} \dfrac{d/dx(3xlnx-3(x-1))}{d/dx((x-1)lnx)}\\\\= \lim_{x \to 1} \dfrac{3x(\frac{1}{x})+ 3lnx-3)}{(x-1)\frac{1}{x} +lnx}\\\\= \lim_{x \to 1} \dfrac{3 + 3lnx-3}{(x-1)\frac{1}{x} +lnx}\\\\= \frac{3ln1}{(1-1)\frac{1}{1} +ln1}\\\\= \frac{0}{0} (ind)[/tex]

Applying L'hospital rule again;

[tex]= \lim_{x \to 1} \dfrac{\frac{d}{dx} (3lnx)}{\frac{d}{dx} ((x-1)\frac{1}{x} +lnx)}\\\\= \lim_{x \to 1} \dfrac{\frac{3}{x} }{(x-1)\frac{-1}{x^2} + \frac{1}{x} +\frac{1}{x} }\\\\= \dfrac{\frac{3}{1} }{(1-1)\frac{-1}{1^2} + \frac{1}{1} +\frac{1}{1} }\\\\= \frac{3}{0(-1)+2}\\ \\= \frac{3}{2-0}\\ \\= 3/2[/tex]

Hence the limit of the function is 3/2.

Answer:

The average speed for the four laps is 9 km/h.

Step-by-step explanation:

The average speed of the four laps can be calculated as follows:

[tex] \overline{v_{T}} = \frac{\overline{v_{1}} + \overline{v_{2}} + \overline{v_{3}} + \overline{v_{4}}}{4} [/tex]

Where:

[tex]\overline{v_{1}}[/tex]: is the average speed for the first lap

[tex]\overline{v_{2}}[/tex]: is the average speed for the second lap

[tex]\overline{v_{3}}[/tex]: is the average speed for the third lap

[tex]\overline{v_{4}}[/tex]: is the average speed for the fourth lap

Hence, the average speed for the four laps is:  

[tex] \overline{v_{T}} = \frac{12 km/h + 10 km/h + 8 km/h + 6 km/h}{4} [/tex]

[tex] \overline{v_{T}} = 9 km/h [/tex]                                      

Therefore, the average speed for the four laps is 9 km/h.

I hope it helps you!
