Answer:

y = 7

Step-by-step explanation:

Simplifying

6y + 3 = 45

Reorder the terms:

3 + 6y = 45

Solving

3 + 6y = 45

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 6y = 45 + -3

Combine like terms: 3 + -3 = 0

0 + 6y = 45 + -3

6y = 45 + -3

Combine like terms: 45 + -3 = 42

6y = 42

Divide each side by '6'.

y = 7

Simplifying

y = 7

Answer: [tex]p = \frac{m - 3n}{2}[/tex]

Step-by-step explanation:

We need to isolate p from the given equation.

m=3n+2p

first lets subtract 3n from both sides to get 2p by itself.

m - 3n = 2p

now lets divide by 2 from both sides

m - 3n = 2p

/2   /2     /2

[tex]p = \frac{m - 3n}{2}[/tex]

Answer:

t = -1, 2

Step-by-step explanation:

Step 1: Define

h(t) = -5t² + 5t + 10

Step 2: Factor

h(t) = -5(t² - t - 2)

h(t) = -5(t - 2)(t + 1)

Step 3: Find roots

0 = -5(t - 2)(t + 1)

0 = (t - 2)(t + 1)

t - 2 = 0

t = 2

t + 1 = 0

t = -1

Answer:

11th month which is November

Step-by-step explanation:

1860 + 45(m - 1) = 2310

1860 + 45m - 45 = 2310

1815 + 45m = 2310

45m = 495

m = 11

In month of November their car sales reached 2310 units.

Given that, a car manufacturing company was able to release 1860 units at the end of January based on records they were able to increase their sales by 45 units per month in what month their car sales reached 2310 units.

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

Let number of months be m.

So, 1860 + 45(m - 1) = 2310

⇒ 1860 + 45m - 45 = 2310

⇒ 1815 + 45m = 2310

⇒ 45m = 495

⇒ m = 11

Therefore, in month of November their car sales reached 2310 units.

Answer: no its a reflection.

Step-by-step explanation:

you can see that no matter how you rotate triangle be it can not get all the angles to match but if you were to fold it in half they are a perfect fit. :)

Triangle B is a reflection of triangle A so the given statement is incorrect.

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).

Given a triangle A.

If we rotate it about line segment l then it will not go to cover wholly triangle B.

If we rotate triangle A clockwise then the corresponding sides will not match.

If we rotate triangle A anti-clockwise then also corresponding sides will not match.

If we reflect the triangle A about line segment l then it will form an mirror image so if we fold triangle A over line l then it will completely cover triangle B.

Hence "Triangle B is a reflection of triangle A so the given statement is incorrect".

The common ratio of 1.5 by which the distance Gavin rides on each subsequent day of 1.5 indicates;

Part A; Day 1; x, Day 2; 1.5·x, Day 3; 1.5²·x, Day 4; 1.5³·x

Part B; Gavin rides 8 meters on day 1, 12 meters on day 2, 18 meters on day 3, and 27 meters on day 4

A common ratio is a value that is used to divide or multiply at each stage in a sequence.

The distance Gavin wants to ride each day = 1.5 × The distance he rode on the previous day

The common ratio of the distance Gavin plan to ride on each subsequent day is 1.5, therefore;

Part A; Where x represents the distance Gavin bikes on the first day, we get;

Day 1; Distance Gavin rides = x

Day 2; Distance he rides = 1.5·x

Day 3; Distance he rides  = 1.5²·x

Day 4; Distance he rides = 1.5³·x

Part B; The equation that represents Gavin's situation can be found from the expression for the distance he rides each day by  adding the distances equating the result to the distance Gavin wants to bike in total, as follows;

x + 1.5·x + 1.5²·x + 1.5³·x = 65

x·(1 + 1.5+ 1.5² + 1.5³) = 65

x = 65/(1 + 1.5+ 1.5² + 1.5³)  = 8

x = 8 meters

The distance Gavin rides on each day are therefore;

Day 1; Distance, x = 8 meters

Day 2; Distance, 1.5·x = 1.5 × 8  = 12 meters

Day 3; Distance, 1.5²·x = 1.5² × 8 = 18 meters

Day 4; Distance, 1.5³·x = 1.5³ × 8 = 27 meters

Answer:

The correct option is d

Step-by-step explanation:

From the question we are told that

The equation is [tex]ln (SALARY) = 1 + 0.02 ln(EDU)[/tex]

generally

[tex]ln (e) = 1[/tex]

=> [tex]ln (SALARY) = ln (e) + 0.02 ln(EDU)[/tex]

Apply log rules

=> [tex]ln (SALARY) = ln[ e(EDU)^{0.02} ][/tex]

=> [tex]SALARY = e(EDU)^{0.02}[/tex]

When EDU is increase by 1% we have that

[tex]\frac{1}{100} * EDU + EDU[/tex]

=> [tex]1.01 EDU[/tex]

So the new SALARY will now be

[tex]SALARY'' = e(1.01EDU)^{0.02}[/tex]

The ratio by which the new SALARY will increase is obtain by dividing the value of new SALARY (SALARY'' ) with that of the former SALARY (SALARY) and this mathematically represented as

[tex] \frac{SALARY'' }{SALARY} = \frac{e*1.01 (EDU)^{0.02}}{e (EDU)^{0.02}}[/tex]

=> [tex]\frac{SALARY ''}{SALARY} = 1.0002[/tex]

Generally the percentage increase of salary is mathematically evaluated as

[tex]k= (\frac{SALARY''}{SALARY} - 1 ) * 100[/tex]

=> [tex]k= (1.0002 - 1 ) * 100[/tex]

=> [tex]k= 0.02 \%[/tex]

Part 1: Using the law of cosines, Car B has to travel a distance of approximately 20 miles to reach the intersection.

Part 2: Car A takes around 0.67 hours to reach the intersection.

Part 3: Car B takes approximately 0.44 hours to reach the intersection.

Part 4: Car B reaches the intersection first, approximately 0.23 hours (or 14 minutes) ahead of Car A.

Part I: To determine how far Car B has to travel to reach the intersection, we can use the law of cosines. According to the diagram, we have a triangle with sides of lengths 20 miles (the distance between the cars) and two unknown sides, which we'll denote as a and b. The angle between the sides of lengths 20 miles and a is given as 90 degrees.

The law of cosines states that in a triangle with sides of lengths a, b, and c, and with the angle between sides a and b denoted as angle C, the following equation holds:

[tex]c^2 = a^2 + b^2 - 2ab * cos(C)[/tex]

In this case, we know that side c has a length of 20 miles, and angle C is 90 degrees. Let's denote the distance Car B has to travel as b. Plugging in these values into the equation, we have:

[tex]20^2 = a^2 + b^2 - 2ab * cos(90)[/tex]

[tex]400 = a^2 + b^2[/tex]

So, Car B has to travel a distance of[tex]\sqrt{ (400)}[/tex] = 20 miles to reach the intersection.

Part II: To determine the time necessary for Car A to reach the intersection, we can use the formula: time = distance / speed. Car A is traveling at a speed of 30 mph, and we know the distance between the cars is 20 miles. Therefore, the time necessary for Car A to reach the intersection is:

time = 20 miles / 30 mph = 0.67 hours (rounded to the nearest hundredth).

Part III: Similarly, for Car B, we can use the same formula: time = distance / speed. Car B is traveling at a speed of 45 mph, and we found that the distance Car B has to travel is 20 miles. Therefore, the time necessary for Car B to reach the intersection is:

time = 20 miles / 45 mph ≈ 0.44 hours (rounded to the nearest hundredth).

Part IV: To determine which car reaches the intersection first, we compare the times calculated in Part II and Part III. Car A takes approximately 0.67 hours to reach the intersection, while Car B takes approximately 0.44 hours. Therefore, Car B reaches the intersection first, and it does so approximately 0.23 hours (or 14 minutes) earlier than Car A.

In summary, Car B reaches the intersection first, traveling a distance of 20 miles, and it does so approximately 0.23 hours (or 14 minutes) earlier than Car A.

Step-by-step explanation:

Answer: D. Fixed costs

Rent is an example of fixed costs. The amount of rent does not change based on how many items are produced. This is assuming you are not changing the size of the location or expanding to another location.

∠( 2x + 36 ) and ∠4x are interior angles on the same side of transversal, which means their sum will add up to 180° .

Which means :-

[tex] = 2x + 36 + 4x = 180[/tex]

[tex] = 6x + 36 = 180[/tex]

[tex] = 6x = 180 - 36[/tex]

[tex] = 6x = 144[/tex]

[tex] = x = \frac{144}{6} [/tex]

[tex]\hookrightarrow\color{hotpink} x = \color{hotpink}24[/tex]

To find whether or not we have found out the correct value of x, let us place 24 in the place of x :-

[tex] = 2x + 36[/tex]

[tex] = 2 \times 24 + 36[/tex]

[tex] = 48 + 36[/tex]

[tex]\color{olive}∠(2x + 36) =\color{hotpink} 84°[/tex]

Then :-

[tex] = 4x[/tex]

[tex] = 4 \times 24[/tex]

[tex]\color{olive}∠4x =\color{hotpink} 96°[/tex]

As , the sum of both these angles are adding upto 180° (84+96=180) , we can conclude that we have found out the correct value of x .

Therefore, the value of :-
