The length of the rectangle is 5 more than twice the width. If the perimeter is 10 times that of the width, what is the width, length, and perimeter of the rectangle?
Width of the rectangle is 2.5, Length is 10 and perimeter is 25
Given
Length of rectangle is 5 greater than double of width
let us say width = w
According to the question length L = 5 + 2w
Perimeter is 10 times the width
P= 10w
we know that perimeter of a rectangle is 2(L+W)
Substituting the values in the formula we get
10w = 2(5+2w + w)
10w = 10 + 6w
w= 2.5
From this length L = 5+2(2.5)
L = 10
Perimeter P = 10W
P= 10(2.5)
P= 25
Hence the length is 10, width is 2.5 and perimeter is 25

Ivan has been given a list of 5 bands and asked to place a vote. His vote must have the names of his favorite, second favorite, and third favorite bands from the list. How many different votes are possible?
Using combinations, there are a total of 20 distinct voting combinations.
We now have five bands. We'll refer to them as A, B, C, D, and E.
John will choose two bands from the available five if he is required to vote for his favorite and second-favorite.
We must pair bands and discover every possible combination in order to determine the TOTAL number of different possibilities.
The results/totals are as follows:
AB, AC, AD, AE
BA, BC, BD, BE
CA, CB, CD, CE
DA, DB, DC, DE
EA, EB, EC, ED
Thus, there are a total of 20 distinct voting combinations.
Since you already know that each of the five initial bands (A, B, C, D, and E) will result in a multiple of four, you may accomplish it more simply without listing by taking the five bands.

Use I = PTR to solve
(time is in years)
I=$252
R=7% find T.
P=$900
The time period in years T = 4 years
The simple interest amount = $252
The rate of interest per year as percentage = 7%
The principal amount = $900
The simple interest I = PTR
Where I is the interest amount
P is the principal Amount
T is the time period involved in years
R is the rate of interest per year as a percent
Substitute the values in the equation
252 = 900 × T × (7 / 100)
252 = 900 × T × 0.07
252 = 63 × T
Move the 63 to other side
T = 252 / 63
T = 4 years
Hence, the time period in years T = 4 years

(10x - 3) ÷ 5 - (1 ÷ 4) = 55 ÷ 4
(7x ÷ 5) - (1 ÷ 4) = 55 ÷ 4
Add (1 ÷ 4) on both sides,

The function which will represent the given Translation will be T(x, y) = (x + 3, y - 2).
Translation may be defined as the shifting of the curve on a graph or shifting of the plotted points on a graph. The translation can be horizontal or vertical. In horizontal direction it can be shifted either left or right and in vertical direction it can be shifted either up or down. Horizontal translation always occurs on the x axis and vertical translation always occurs on the y axis. A function may be defined as an expression in which for input variable x there is output variable y. We need to translate a function T(x, y) 3 units right so the new coordinate will be T(x + 3, y). Now, translation occurs 2 units down. so, new coordinates will be T(x + 3, y -2) which is the required function.

.
The cost of t shirt is $ 133.
What does cost price mean?Cost price is the complete sum of money that a manufacturer must spend to create a specific good or render a specific service.
For instance, Cost price equals selling price plus revenue ( when selling price and profit is given ) Cost is equal to Selling price plus Loss ( when selling price and loss is given ) Cost price = 100 Selling Price + 100 + Profit (where the Selling Price and Profit Percentage are supplied)

The function f(x) = 210-60x represents a second trip, where f(x) is the number of miles
the car is from its destination after x hours. Which trip takes less time? Explain.
Answer:
the trip represented by f(x) takes less time
Step-by-step explanation:
Given a table of time and distance to go, and a function f(x) = 210-60x representing the same for a different trip, you want to know which trip takes less time.
TableThe table has values ...
(time in hours, remaining distance in miles) = (1, 150), (2, 100), (3, 50)
This shows you the remaining distance decreases by 50 miles for every hour added to the travel time. That means the remaining 50 miles will be reduced to zero after 4 hours.
The trip represented by the table takes 4 hours.
EquationThe function f(x) = 210-60x will have a value of zero when ...
0 = 210 -60x
0 = 3.5 -x . . . . . . divide by 60
x = 3.5 . . . . . . . . add x
The trip represented by the function f(x) takes 3.5 hours.

HELP PLS Write the equation of the line in fully simplified slope-intercept form.
The equation of the line that passes through the x-intercept ( -2,0 ) and y-intercept ( 0,1 ) is y = (1/2)x + 1.
What is the equation of line of the graph?The formula for equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
From the graph, the x and y-intercept are; ( -2,0) and (0,1 )
Point 1 ( -2,0 )
x₁ = -2y₁ = 0Point 2( 0,1 )
x₂ = 0y₂ = 1First, we determine the slope of the line.
Slope m = y₂ - y₁ / x₂ - x₁
Slope m = 1 - 0 / 0 - (-2)
Slope m = 1 / 0 +2
Slope m = 1/2
Next, determine the y-intercept b by substituting the slope and a point into the equation of line formula.
y = mx + b
0 = (1/2)(-2) + b
0 = -2/2 + b
0 = -1 + b
b = 1
Now that the values of slope m and y-intercept b is known, plug these into y = mx + b to determine the equation of the line.
y = mx + b
y = (1/2)x + 1
Therefore, the equation of the line is y = (1/2)x + 1.

Julia must sell no less than $330 worth of tacos and burritos each day. If 42 burritos were sold, determine all possible values for the number of tacos that Julia must sell in order to meet the requirements. Your answer should be a comma separated list of values. If there are no possible solutions, submit an empty answer.
The point would be the solution (25,40).

on vacation?
The number of days Henry can go on vacation is 7 days.
Given that, Henry knows it will cost $300 per day that he's on vacation plus $650 for miscellaneous activities.
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 the number of days be x.
Henry has $2750 dollars in his savings account.
So equation is 300x+650=2750
The obtained equation can be solved as follow
300x=2750-650
⇒ 300x = 2100
⇒ x = 2100/300

A piggy bank contains $2.65 in nickles and dimes. if the number of nickles is 7 less than three times the number of dimes. how many of each are there
In this question, we have been given a piggy bank contains 2.65$ in nickels and dimes. Then There are 29 nickels and 12 dimes in the piggy bank.
We need to find the number of nickels and dimes if the number of nickels is 7 less than three times the number of dimes.
Let x be the number of nickels and y be the number of dimes.
We know that, 1 dollar = 20 nickels
and 1 dollar = 10 dimes
So, we get an equation
0.05x + 0.1y = 2.65 ...........(1)
Also the number of nickels is 7 less than three times the number of dimes.
x = 3y - 7 .................(2)
Substitute above value of x in equation (1)
0.05(3y - 7) + (0.1)y = 2.65
0.15y - 0.35 + 0.1y = 2.65
0.25y = 2.65 + 0.35
0.25 y = 3
y = 12
Substitute above value of y in equation (2)
x = 3(12) - 7
x = 29
Therefore, there are 29 nickels and 12 dimes in the piggy bank.
