Justin is a software salesman. His base salary is 1900
, and he makes an additional 50
for every copy of English is Fun he sells.
Let P
represent his total pay (in dollars), and let N
represent the number of copies of English is Fun he sells. Write an equation relating P
to N
. Then use this equation to find his total pay if he sells 27
copies of English is Fun.
Answer:
3250 is your total; p = 50n + 1900 is your equation.
Step-by-step explanation:
"p" represents total pay; "n" represents the number of copies he sells.
Base salary is 1900, and each copy sold gives him an extra 50
p = 50n + 1900 is your equation.
If he sells 27 copies. Plug in 27 for n
p = 50n + 1900
p = 50(27) + 1900
Simplify. Remember to follow PEMDAS. First, multiply, then add.
p = 50(27) + 1900
p = 1350 + 1900
p = 3250

A car dealer sells a car for RS 23500 and makes a profit of RS 10500. At what price did he sell the car?
Answer:
RS 34000
Step-by-step explanation:
Price of the car = RS 23500
Profit = RS 10500
Selling price of the car = Price of the car + Profit
= Rs 23500 + RS 10500
= RS 34000
solve the system by substitution and show all work:
2.5x-3y=-13
3.25x-y=-14
Answer:
(-4,1)
Step-by-step explanation:
A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. Substitution can be used by substituting the value of one variable into the equation.
Pair 2.5x-3y=-13 and 3.25x-y=-14
We can solve for y in 3.25x-y=-14. 3.25x+14=y.
Because y=3.25x+14, we can substitute 3.25x+14 into y in 2.5x-3y=-13.
2.5x-3y=-13
2.5x-3(3.25x+14)=-13
2.5x-9.75x-42=-13
-7.25x-42=-13
-7.25x=29
x= -4
We now substitute x=-4 into y=3.25x+14
y=3.25x+14
y=3.25(-4)+14
y=-13+14
y=1
To solve the system by substitution, solve one equation for one variable and then substitute that expression into the second equation. Solve the resulting equation and then substitute the solution back into one of the original equations to find the other variable.
Explanation:Given the equations:
2.5x - 3y = -143.25x - y = -14Let's find the value of 'x' from the second equation:
y = 3.25x + 14
This formula for 'x' can be substituted into the first equation, resulting in a new equation:
2.5(3.25x + 14) - 3y = -14,
This equation can be simplified and solved to find the variable 'y'. The value of 'y' can then be substituted back into the original equation to find the value of 'x'.
The solution to these two equations, (x, y), is the point of intersection which describes the system of the original equations.

Answer:
A
Step-by-step explanation:
We can find the surface area of the object by adding the surface areas of each part. We have many rectangle faces to count and two triangular faces. Each has a formula for the area. We will find the area of each and then add them all together.
Triangle - 0.5 *b*h
Rectangle - b*h
Triangles
There are two triangles on either side. The height is 1.5. The base is 1.8.
0.5(1.5)(1.8)=1.35 meters squared
Since there are two, we will add 1.35+1.35 in our final calculation.
Rectangles
We will start by calculating the largest rectangle on the side. It has height of 4 and a base of 2.5 (shown above left).
4(2.5)=10
Since there are two (one we can see and one we can't), we will add 10+10 in our final calculation.
Next we calculate the top and bottom. The height is 3 and the base is 2.5 on top. But the bottom sticks out more and adds 1.8 to its base.
Top - 3(2.5)=7.5
Bottom-3(2.5+1.8)=12.9
Finally, we will calculate the front side and back(not visible) as well as the slant up front. The back side has height 4 and base 3. The front side has base 3 and height 4-1.5=2.5. The slant has base 2.3 and height 3.
Back - 4(3)=12
Front- 3(2.5)=7.5
Slant - 3(2.3)=6.9
We add all together for the total surface area: 1.35+1.35+10+10+7.5+12.9+12+7.5+6.9=69.5 meters squared.

A stack of three hundred cards is placed next to a ruler, and the height of stack is measured to be 5/8 of an inch. How thick is one card?
To calculate the thickness of one card from a stack of three hundred cards with a total height of 5/8 inch, you divide the total height by the number of cards, resulting in roughly 0.0020833 inches per card.
To compute the thickness of one card from a stack of three hundred cards, we must first determine the total height of the stack, which we already know is 5/8 of an inch. Then, we simply divide this height by the number of cards, which is 300, to find the thickness of a single card.
Here is the calculation:
Total height of the stack = 5/8 inch
Number of cards in the stack = 300
Thickness of one card = Total height of the stack
Number of cards
Thickness of one card = (5/8 inch)
300
Thickness of one card = 5/8
300
Thickness of one card = 0.0020833... inches (approx.)
Therefore, each card is approximately 0.0020833 inches thick.
Use the factor Theorem to determine whether h(x)=x-1 is a factor of f(x)=14x^99-65x^56+51.
A. Yes
B. No
Factor theorem: if x-k is a factor of p(x), then p(k) = 0. The same can be said in reverse: if p(k) = 0, then x-k is a factor of p(x).
In this case, x-1 = x-k so k = 1. We'll plug this into f(x) below
f(x) = 14x^99 - 65x^56 + 51
f(1) = 14(1)^99 - 65(1)^56 + 51 ... replace every x with 1
f(1) = 14(1) - 65(1) + 51
f(1) = 14 - 65 + 51
f(1) = -51 + 51
f(1) = 0
The result is 0, so h(x) = (x-1) is a factor of f(x) = 14x^99-65x^56+51

Mr. Shaw sells used cars. He earned $250 for selling 5 cars. Mr. Shaw earned $400 for selling 11 cars. Which of the following equations represents this situation, where c represents the number of cars Mr. Shaw sold and e represents the amount he earned?
a: e = 50c + 125
b: e = 25c + 125
c: e = 50c
d: e = 25c
Answer:
b. [tex]e=25c+125[/tex]
Step-by-step explanation:
We are told that Mr. Shaw earned $250 for selling 5 cars. Mr. Shaw earned $400 for selling 11 cars.
We can see that earnings of Mr. Shaw depends on selling of car, so selling of cars will be independent (x) and total earnings will be dependent (y).
Let us find slope of our line with given points (5,250) and (11,400)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{400-250}{11-5}[/tex]
[tex]m=\frac{150}{6}=25[/tex]
This means that Mr. Shaw earns $25 for selling each car.
Now let us find equation of our line in slope intercept formula.
[tex]y=mx+b[/tex], where m= Slope and b= y- intercept.
Let us find b for our equation substituting coordinates of point (5,250) and m=25 in slope intercept form of equation.
[tex]250=25*5+b[/tex]
[tex]250=125+b[/tex]
[tex]250-125=b[/tex]
[tex]125=b[/tex]
[tex]y=25x+125[/tex]
Now let e represent the amount earned by Mr. Shaw and c represent the number of cars sold.
So our equation will be: [tex]e=25c+125[/tex] and option b is the correct choice.
The correct equation that represents Mr. Shaw's earnings from selling cars, where c is the number of cars sold and e is the earnings, is Option b: e = 25c + 125, because it correctly translates the given scenarios into mathematical terms.
The equation correctly represents the situation where c represents the number of cars Mr. Shaw sold and e represents the amount he earned from selling those cars.
To solve this, let's plug the values given into the options provided and see which one fits. For the first scenario, selling 5 cars earned him $250, and selling 11 cars earned him $400.
Option a: e = 50c + 125
For 5 cars: e = 50(5) + 125 = 250 + 125 = 375 (Incorrect)
For 11 cars: e = 50(11) + 125 = 550 + 125 = 675 (Incorrect)
Option b: e = 25c + 125
For 5 cars: e = 25(5) + 125 = 125 + 125 = 250 (Correct for 5 cars)
For 11 cars: e = 25(11) + 125 = 275 + 125 = 400 (Correct for 11 cars)
Option c: e = 50c
This option does not include the fixed amount, thus incorrect based on the provided values.
Option d: e = 25c
This option also does not consider a fixed starting amount, making it incorrect for our situation.
Hence, the correct equation is Option b: e = 25c + 125.
A carpenter needs to make 60 dowels.Each dowel must be 6 inches long.The wood from which the carpenter will cut the dowels comes in 4-foot lengths.What is the least number of 4-foot Lengths of wood the carpenter can buy and still make all 60 dowel
Answer: 8
Step-by-step explanation:
60 dowels - each 6 inches (1/2 foot) in length = 30 feet of wood
30 feet of wood ÷ 4 foot boards = 7.5 boards
Since he can't buy half of a board, you must round up to 8 boards.
The question involves a conversion of measurements. After converting 4 feet to 48 inches, it's calculated that one piece of wood can produce 8 dowels. To make 60 dowels, you would need 7.5 pieces of wood, but this rounds up to 8 pieces since half a piece cannot be bought.
Explanation:To answer this question, we first need to understand that all measurements need to be in the same units. Since our dowels are in inches (6 inches long) and our wood lengths are in feet (4 feet long), we need to convert one to the other. For simplicity's sake, let's convert the feet to inches as follows: 1 foot = 12 inches, therefore, 4 feet = 48 inches.
Then, we can find out how many dowels we can get from just one piece of wood: 48 inches / 6 inches per dowel = 8 dowels per one piece of 4-foot wood.
Lastly, to find out how many pieces of wood are needed to make 60 dowels, we divide the total number of dowels by the number of dowels per wood: 60 dowels / 8 dowels per wood = 7.5. Since we can't purchase half a piece of wood, we have to round up, so the carpenter needs to buy a minimum of 8 pieces of 4-foot wood to have enough to make 60 dowels.

Find the measure of x and y in the isosceles triangle shown below:
x=22, y=136
x=22, y=48
x=44, y=65
x=20, y=65
Answer:
x=22, y=48
Step-by-step explanation:
If this is an isosceles triangle, then <G is equal to <J
<g = <j
x+44 = 3x
Subtract x from each side
x+44-x = 3x-x
44= 2x
Divide each side by 2
44/2 = 2x/2
22= x
The three angles of a triangle add to 180 degrees
<G + <J + <H = 180
x+44 + 3x + y = 180
22+44 +66 + y = 180
Combine like terms
132+ y =180
Subtract 132 from each side
132-132+y = 180-132
y = 48

Maya is camping at the top of mount Armstrong at an elevation of 7,832 meters. Juan is scuba diving 160 meters below sea level In Lake Junction, which is the base of mount Armstrong. The two decide to meet at the midpoint to have a picnic. At what elevation will maya and John meet
Answer:
Elevation = [tex]39996-160=3836[/tex] meters (taking base of Mt. Armstrong as sea level)
Step-by-step explanation:
The midpoint will be the half of their total distance.
If we take base of Mt. Armstrong to be 0, then Maya's distance is 7832 meters ABOVE and Juan's distance is 160 meters BELOW that.
The distance between them is thus [tex]7832+160=7992[/tex] meters.
We take half of this, to find midpoint. So:
[tex]\frac{7992}{2}=3996[/tex] meters
This is 3996 meters from Juan or from Maya. If the picnic is going to be at 3996 meters ABOVE Juan and since base of mountain is where we start measuring, we subtract 160 (Juan's distance from base) from 3996 to get the ELEVATION.
Elevation = [tex]39996-160=3836[/tex]

A level 0.90 confidence interval is
A) any interval with margin of error ± 0.90.
B) an interval computed from sample data by a method that has probability 0.90 of
producing an interval containing the true value of the parameter of interest.
C) an interval with margin of error ± 0.90, which is also correct 90% of the time.
D) an interval computed from sample data by a method that guarantees that the probability
the interval computed contains the parameter of interest is 0.90.
Answer:
Option B is correct.
Step-by-step explanation:
Confidence interval is the range of the values that the particular probability whose value will lie in the interval.
So, if a level is 0.90 confidence interval it means the value of the probability will lie in the given level.
Therefore, Option B is correct that is an interval computed from sample data by a method that has probability 0.90 of producing an interval containing the true value of parameter of interest.
A 0.90 confidence interval is an interval computed from the sample data, with a probability of 0.90 that it contains the true value of the parameter of interest. The margin of error may vary and is not necessarily ±0.90. No method can absolutely guarantee a 0.90 probability.
Explanation:A 0.90 confidence interval, in statistical terms, is most accurately defined as an interval computed from sample data by a method that has a probability of 0.90 of producing an interval containing the true value of the parameter of interest. Therefore, the correct answer to this question is option B).
When we say that we're 90% confident, what we're implying is that if we were to repeat the same experiment 100 times, we'd expect the true parameter to lie within the confidence interval 90 times. The margin of error isn't necessarily ±0.90 as suggested by some of the other options (A and C) - it could be any value, depending on the data.
Option D suggests the method guarantees a 0.90 probability. It's crucial to understand that a confidence interval doesn't give such a guarantee; it provides an estimate and there’s always a certain amount of uncertainty.

Maria studied the traffic trends in India. She found that the number of cars on the roads increases by 10% each year. If there were 80 million cars in year 1 of her study, how many more cars were on the road in year 3 compared to year 2? 8,000,000 8,800,000 88,000,000 96,800,000
Answer:
B) 8, 800, 000
Step-by-step explanation:
The number of cars in year 1= 80,000,000
She found that the number of cars on the roads increases by 10% each year.
Now let's find 10% of 80,000,000
= [tex]\frac{10}{100} *80,000,000 = 8,000,000[/tex]
So the number of cars in year 2= 80,000,000 + 8,000,000
= 88,000,000
Now let's find 10% of 88,000,000.
= [tex]\frac{10}{100} *88,000,000 = 8,800,000[/tex]
So the number of cars in year 3= 88,000,000 million+8,800,000= 96,800,000
Now we have to find difference in year 3 compared to in year 2.
The difference in the cars in year 3 compared to year 2= 96,800,000 - 88,000,000
= 8,800,000
Therefore, the answer is B) 8, 800, 000
