Answer:
Step-by-step explanation:
let x be the price of ticket,then
120-x=3(80-x)
120-x=240-3x
3x-x=240-120
2x=120
x=120/2=60
Price of ticket=$60
Mr.Chandra has 80-60=20 $ after buying the ticket.

The measure of an angle is 18.2°. What is the measure of its complementary angle?
find the value of x.
Hey there!
To find the value of x in an equation, you have to solve for x.
Example
Given: 3x - 9 = 0
First, add 9 to both sides:
3x = 9
Then, divide both sides by 3
x = 3

3(n – 1) = 6
How do I solve this equation?
Answer:
n=3
Step-by-step explanation:
distribute, then add 3 to both sides, then divide both sides by 3
Answer:
n = 3
Step-by-step explanation:
3(n−1)=6
Step 1: Simplify both sides of the equation.
3(n−1)=6
(3)(n)+(3)(−1)=6(Distribute)
3n+−3=6
3n−3=6
Step 2: Add 3 to both sides.
3n−3+3=6+3
3n=9
Step 3: Divide both sides by 3.
3n/3 = 9/3\
n= 3

Traveling Salesperson Suppose you are a salesperson who must visit the following 23 cities: Dallas, Tampa, Orlando, Fairbanks, Seattle, Detroit, Chicago, Houston, Arlington, Grand Rapids, Urbana, San Diego, Aspen, Little Rock, Tuscaloosa, Honolulu, New York, Ithaca, Charlottesville, Lynchville, Raleigh, Anchorage, and Los Angeles. Leave all your answers in factorial form.
a. How many possible itineraries are there that visit each city exactly once?
b. Repeat part (a) in the event that the first five stops have already been determined.
c. Repeat part (a) in the event that your itinerary must include the sequence Anchorage, Fairbanks, Seattle, Chicago, and Detroit, in that order.
Answer:
1. 23!
2. 18!
3. 19!
Step-by-step explanation:
1.
We start by the order that we were given. Dallas is the first City with los Angeles being the last.. a total of 23 states.
Dallas can be placed in any of the 23 positions.
Tampa can be placed in any of the remaining 22 positions and so on.
Such that we have
Total number of ways = 23x22x21...x1 ways
= 23!
2. If first 5 cities have been determined,
23-5 = 18 cities
We can arrange in (23-5)! Ways
= 18!
3. We consider these 5 cities to be 1 unit, so we have to arrange the remaining 18 cities plus this single unit.
Total number of ways = (18+1)!
= 19!

Find the value of x.
х
50°
The unknown value of x from the diagram is 80 degrees.
The given diagram is an isosceles triangle.
The base angle of an isosceles triangle are equal
The sum of angle in a triangle is also 180 degrees. Hence:
x + 50 + 50 = 180
x + 100 = 180
Subtract 100 from both sides
x + 100 - 100 = 180 - 100
x = 80 degrees
Hence the unknown value of x from the diagram is 80 degrees.

Find the greatest common factor of 7x and 4x?.
Answer:
GCF = x
Step-by-step explanation:
The factor decomposition is:
7 * x for the first term
2 * 2 * x for the second term.
The ONLY common factor is "x", and the maximum power at which it appears in BOTH terms is "1" (one)
Therefore GCF = x
Sandy spent 20% of x hours at her part-time job.What is x if 20% of x is about 26 hours?
Can someone help me with this? #1 first please
Answer:
Ok so you did the first box of statements and reasons correct. Now let us look at the second box of statements and reasons. There is also one more given statements and reasons and it is RS is congruent to TS. That is going to be a given one. Now if you look at the prove sections, it says to prove angle RSV is congruent to angle TSV. In the comments section let us find the answer together. I know the answers, but you give it a try too. I will give you a hint that the triangle is a AAS postulate (Angle-Angle-Side).
Find the area of a rectangle with a length of
14 ft and width of 28 ft.
Answer:
392 ft^2
Step-by-step explanation:
area = length * width
a = lw
392 = 14 * 28
Don't forget the unit is ft^2 since we are finding the area of a 2-dimensional shape in feet!
Answer:
Step-by-step explanation:
the area of a rectangle is L*W
A=14*28=392 ft^2
A decreased by 20% and then increased by 20% express using algebra
asapppppp
Answer:
96%
Step-by-step explanation:
assume the whole number is x
the first thing is decreasing by 20 %
x - 20%x = 80% x
then now the 80%x is the whole number
now It's the turn of increasing
80%x + 20% * (80% x) = 80%x + 16%x = 96% x

Step-by-step explanation:
During a test period, an experimental group of 10 vehicles using an 85 percent ethanol-gasoline mixture showed mean CO2 emissions of 240 pounds per 100 miles, with a standard deviation of 20 pounds. A control group of 14 vehicles using regular gasoline showed mean CO2 emissions of 252 pounds per 100 miles with a standard deviation of 15 pounds. A quick comparison of the sample variances suggests that the population variances are:
a. probably equal.
b. probably unequal.
c. incomparable.
Answer:
Probably unequal ( B )
Step-by-step explanation:
experimental group = 10
using 85% ethanol gasoline
mean = 240 pounds per 100 miles
standard deviation = 20 pounds
control group = 14 vehicles
using regular gasoline
mean = 252 pounds per 100 miles
standard deviation = 15 pounds
comparing the sample variance of each group shows that they are probably unequal using the equation below
Variance for a sample set of data = ∑ ( x - X ) ^2 / n - 1
where n = number of events
X = mean value
x = value of events
