The length of a rectangle is 5 centimeters less than twice its width. The perimeter of the rectangle is 26 cm. What are the dimensions of the rectangle?
A. length = 7 cm; width = 6 cm
B. length = 4 cm; width = 9 cm
C. length = 6 cm; width = 7 cm
D. length = 5 cm; width = 5 cm
Answers
Use w to represent width, p as perimeter, and l for length.
l = 2w - 5
2l + 2w = p
2(2w - 5) + 2w = 26
4w - 10 + 2w = 26
6w - 10 = 26
6w = 36
w = 6
The only option with a width of 6 is A.
To check your answer, you can plug it in.
2(6) - 5 = 12 - 5 = 7
Hope this helps.
The correct option is [tex]\boxed{\text{\bf option C}}[/tex] i.e., the length is [tex]6\text{ cm}[/tex] and breadth is [tex]7\text{ cm}[/tex].
Further explanation:
The perimeter of arectangle is calculated as follows:
[tex]\boxed{\text{Perimeter}=2\cdot (l+b)}[/tex]
Here, [tex]l[/tex] is the length and [tex]b[/tex] is the breadth of the rectangle.
Given:
The length of the rectangle is [tex]5\text{ cm}[/tex] less than twice its breadth and the perimeter of the rectangle is [tex]26\text{ cm}[/tex].
Calculation:
Step 1:
First we write the dimensions in the form of variable [tex]x[/tex].
Consider [tex]x[/tex] as the breadth of the rectangle and [tex]y[/tex] as the length of the rectangle.
As per the question the length is [tex]5\text{ cm}[/tex] less than twice its breadth.
Therefore, the length can be expressed in the form of the equation as follows:
[tex]\boxed{y=2x-5}[/tex] …… (1)
Step 2:
Now, we have to calculate the dimensions of the rectangle.
So, substitute [tex]l=2x-5[/tex] and [tex]b=x[/tex] in the formula of the perimeter of the rectangle to obtain the value of [tex]x[/tex].
[tex]\begin{aligned}\text{Perimeter}&=2\cdot (l+b)\\26&=2\cdot (2x-5+x)\\26&=2\cdot (3x-5)\\26&=6x-10\\6x&=26+10\\6x&=36\\x&=6\end{aligned}[/tex]
Therefore, the breadth of the rectangle is [tex]6\text{ cm}[/tex].
Now, substitute [tex]x=5[/tex] in the equation (1) to obtain the value of the length.
[tex]\begin{aligned}l&=2x-5\\&=(2\cdot 6)-5\\&=12-5\\&=7\end{aligned}[/tex]
Therefore, the length of the rectangle is [tex]7\text{ cm}[/tex].
Thus, the correct option is [tex]\boxed{\text{\bf option C}}[/tex] i.e., the length is [tex]6\text{ cm}[/tex] and breadth is [tex]7\text{ cm}[/tex].

A total of 820 tickets were sold for the school play. they were either adult tickets or student tickets. there were 70 more student tickets sold than adult tickets. how many adult tickets were sold?
Answers
By setting up a system of equations, we find that 375 adult tickets were sold for the school play.
To solve this problem, we need to set up a system of equations using the information provided:
There are only two types of tickets: adult tickets and student tickets.A total of 820 tickets were sold.There were 70 more student tickets sold than adult tickets.Let's define the following variables:
A for the number of adult tickets.S for the number of student tickets.According to the problem:
A + S = 820 (since the total number of tickets is 820)S = A + 70 (since there are 70 more student tickets than adult tickets)Now we substitute the second equation into the first:
A + (A + 70) = 8202A + 70 = 8202A = 750A = 375So, 375 adult tickets were sold.
Hot dogs cost $2.00 each, candy bars cost $1.00 each, and soft pretzels cost $2.50 each. How much would it cost to buy two hot dogs and one candy bar?
a. too much
b. too little
Answers
To calculate the total cost, multiply the price of each item by the number purchased then add those totals together. In this case, purchasing two hot dogs and one candy bar costs $5.00.
Explanation:To find the total cost of purchasing two hot dogs and one candy bar, you would simply multiply the cost of each item by the number of that item you are buying, and then add all these costs together. So, if a hot dog is $2.00 and you want to buy two, this costs $2.00 * 2 = $4.00. A candy bar is $1.00 each, and if you want to buy one, this costs $1.00 * 1 = $1.00. So, the total cost would be the cost of the hot dogs plus the cost of the candy bar, which is $4.00 + $1.00 = $5.00. Therefore, the total cost of two hot dogs and one candy bar is $5.00.

For the given function, find the vertical and horizontal asymptote(s) (if there are any). f(x) = the quantity x squared plus three divided by the quantity x squared minus nine
Answers
__________________________________________
The horizontal asymptote is: "y = 2" .
___________________________________________
Explanation:
___________________________________________
f(x) = [tex] \frac{x^{2}+ 3}{ x^{2} - 9}[/tex] ;
We know that "(x² − 9) ≠ 0 ; since we cannot divide by "0" ; so the "denominator" in the fraction cannot be "0" ;
since: 9 − 9 = 0 ; "x² " cannot equal 9.
So, what values for "x" exist when "x = 9" ?
x² = 9 ;
Take the square root of EACH SIDE of the equation ; to isolate "x" on one side of the equation ; and to solve for "x" ;
√(x²) = √9 ;
x = ± 3

So; the vertical asymptotes are: "x = 3" and "x = -3" .

Mark the statements that are true.
A. An angle that measures is a reflex angle.
B. An angle that measures 65 is an acute angle.
C. An acute angle measures less than .
D. An angle that measures 300 is an obtuse angle.
Answers
The correct options are B. An angle that measures 65 is an acute angle. and C. An acute angle measures less than 90 degrees.
To determine the truth of each statement, let's analyze each option:
A. An angle that measures 180 degrees is a reflex angle.
This statement is false. An angle that measures exactly 180 degrees is a straight angle, not a reflex angle. A reflex angle is greater than 180 degrees but less than 360 degrees.
B. An angle that measures 65 degrees is an acute angle.
This statement is true. An acute angle is an angle that measures less than 90 degrees. Since 65 degrees is less than 90 degrees, it is indeed an acute angle.
C. An acute angle measures less than 90 degrees.
This statement is true. By definition, an acute angle is any angle whose measure is less than 90 degrees.
D. An angle that measures 300 degrees is an obtuse angle.
This statement is false. An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. Since 300 degrees is greater than 180 degrees, it is not an obtuse angle but rather a reflex angle.

Why might a person need an emergency fund?
Answers
Answer:
To prepare for the unexpected, it is important to have a reserve fund set aside. Having a reserve fund is important, but it should not always be your first priority. If you have credit card or other debt, pay that off before you start to put your money in a reserve. Credit card debt has a high interest rate, while the money that you will save in your reserve probably won’t gain a lot of interest. Why not? When you choose a place to save your financial reserve, low risk is key. Remember that your financial reserve fund is for emergencies only. If you have an emergency and need to use it, do. Once you are back on your feet, replenish it. Also, once you have saved the amount you need, stop. Your extra savings will serve you better in an investment that yields higher interest.
