Make p the subject of the formula
m=3n+2p
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]

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
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.
What is an equation?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.

4. Two cars are starting from positions that are 20 miles apart. They are both headed for the same intersection, as depicted in the diagram below. Car A is traveling at 30 mph, and Car B is traveling at 45 mph. Which car will reach the intersection first?
Part I: Use the law of cosines to determine how far Car B has to travel to reach the intersection. (2 points)
Part II: Use to determine the time necessary for Car A to reach the intersection. Round your answer to the nearest hundredth of an hour. (1 point)
Part III: Use to determine the time necessary for Car B to reach the intersection. (1 point)
Part IV: Which car reaches the intersection first, and by how many hours? (2 points)
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.

How do you interpret the estimated value of coefficient of EDU in the following equation:
ln(SALARY)= 1 + 0.02ln(EDU)
where SALARY is annual salary (in thousands) and EDU is years of education?
a.
we predict that 1 year increase in years of education leads to $2000 increase in salary
b.
we predict that 1% increase in years of education leads to 2% increase in salary
c.
we predict that 1 year increase in years of education leads to 2% increase in salary
d.
we predict that 1% increase in years of education leads to 0.02% increase in salary
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]

Use the spinner below to answer the question. Assume that it is equally probable that the pointer will land on any one of the five numbered spaces. If the pointer lands on a borderline, spin again. A spinner consists of a pointer on a circle divided into five equally-sized sections by five line segments that run from the circle's center to its edges. In clockwise order, the sectors are labeled "1," "2," "3," "4," and "5." Find the probability that the arrow will land on an odd number.
Answer:
The probability that the arrow will land on an odd number is 0.60.
Step-by-step explanation:
We are given that a spinner consists of a pointer on a circle divided into five equally-sized sections by five line segments that run from the circle's center to its edges.
In clockwise order, the sectors are labeled "1," "2," "3," "4," and "5."
As we know that the probability of any event is given by;
Probability, P(E) = [tex]\frac{\text{Favorable number of outcomes}}{\text{Total number of outcomes}}[/tex]
Now, the probability that the arrow will land on an odd number is given by;
Total number of sectors = 5
Odd number of sectors = 1, 3, 5 = 3
So, the required probability = [tex]\frac{3}{5}[/tex] = 0.60
Hence, the probability that the arrow will land on an odd number is 0.60.

[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 :-
[tex]\boxed{\color{olive}x \: \:\bold{\color{hotpink} = 24}}[/tex]
What is the answer to this combination lock
Answer: 375
Step-by-step explanation:
Ruling out each number:
6: In the first two rows, the 6's placement did not change but the clue did, meaning that it is talking about a different number. Otherwise, it would say it's in the right place twice or in the wrong place twice.
3 & 5: Since we know 6 is already ruled out, both 5 & 3 would have to be correct.
2 & 4 & 8: Is proven wrong in the 4th clue.
7: 7 would have to be in the middle since the second clue says it's in the wrong place. If it was 1, it would say it's in the right space.
1: Is proven wrong after 7 is proven true.
Figuring out placement:
5: For the first clue, it says that it's in the correct place meaning that 5 is the last digit.
3: For both of the times 3 appears, it is in the wrong spot, revealing that it's the first digit.
7: In the second clue, it could either be 1 or 7. However, since 3 took the first spot and 5 took the last spot, 7 would have to be in the middle since the clue says it's in the wrong place. If it was 1, it would say it's in the right space.
