How to find 0.36 repeating in a equivalent fraction form?
To convert 0.36 repeating into a fraction, we get [tex]\frac{4}{11}[/tex].
To convert the repeating decimal 0.36 repeating (written as 0.363636...) into a fraction, follow these steps:
Let x = 0.363636...Multiply both sides of the equation by 100 (since the repeating part is two digits long):⇒ 100x = 36.363636...
Subtract the original equation from this new equation:⇒ 100x - x = 36.363636... - 0.363636...
⇒ 99x = 36
Solve for x:⇒ x = [tex]\frac{36}{99}[/tex]
Simplify the fraction by finding the greatest common divisor (GCD) of 36 and 99, which is 9:⇒ x = ([tex]\frac{36}{99}[/tex]) / ([tex]\frac{99}{9}[/tex]) = [tex]\frac{4}{11}[/tex]
Therefore, the fraction equivalent of 0.36 repeating is [tex]\frac{4}{11}[/tex].

Let $abcd$ be a parallelogram. extend $\overline{bc}$ past $b$ to $f$, and let $e$ be the intersection of $\overline{ab}$ and $\overline{df}$. if the areas of triangles $bef$ and $ade$ are 1 and 9, respectively, find the area of parallelogram $abcd$.
Triangles ade and bef are similar due to equal angles. The ratio of their areas (9:1) means their sides have a ratio of 3:1. Using the properties of parallelograms, the parallelogram's area will be double the area of triangle ade, or 18 square units.
Explanation:In the given problem, we have a parallelogram abcd and we're asked to find its area. Given the properties of a parallelogram, we know that angle bad equals angle bef. This leads to the conclusion that triangle ade is similar to triangle bef since their angles are the same. As the ratio of their areas is 9:1, it's clear the ratio of their sides is 3:1, since the ratio of the areas of similar figures is the square of the ratio of their corresponding sides.
The parallelogram's area will be double the area of triangle ade, thanks to the properties of a parallelogram (it's made up of two congruent triangles). Therefore, the area of the parallelogram is 18 square units. The important steps here were recognizing the similar triangles and knowing how to calculate a parallelogram's area.

A company has a $150 budget to provide lunch for its 20 employees. The options are to provide either roast beef sandwiches, which cost $5 apiece, or tuna sandwiches, which also cost $5 apiece. The company also wants to use the entire budget. Suppose r represents the number of roast beef sandwiches it provides and t represents the number of tuna sandwiches. Which statement is correct?
A. The company can provide lunch for all 20 employees and use the entire budget because there is a solution to the system of equations r-t=20 and 5r+5t=150.
B. The company can provide lunch for all 20 employees and use the entire budget because there is a solution to the system of equations r+t=20 and 5r+5t=150.
C. The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r-t=20 and 5r-5t=150.
D. The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r+t=20 and 5r+5t=150.
Answer: D. The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r+t=20 and 5r+5t=150.
Step-by-step explanation:
Let 'r' represents the number of roast beef sandwiches it provides and 't' represents the number of tuna sandwiches.
Then, the total number of roast beef sandwiches and tuna sandwiches is equal to the number of employees :
[tex]r+t=20[/tex]....................(1)
Also, the cost of each roast beef sandwich and cost of each tuna sandwich is same as $5.
If company wants to use the entire budget of $150, then we have another equation :-
[tex]5r+5t=150\\\5(r+t)=150[/tex]
If we divide 5 on both sides we get
[tex]r+t=30[/tex].............................(2)
When we compare equation (1) and (2) we get 20=30 but it is not possible therefore the system has no solution.
Therefore, the correct statement is "The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r+t=20 and 5r+5t=150."

B.False
Answer: false
Step-by-step explanation:
The equation y = ax describes the graph of a line. If the value of a is negative, the line
The equation y = ax represents a straight line with slope a. If a is negative, the line slopes downward to the right, not down and to the left.
The equation y = ax describes the graph of a line. The & in the equation appears to be a typo and should likely refer to a. The constant a represents the slope of the line. When the slope a is negative, the line slopes downward as it moves to the right on a coordinate plane. This is because a negative slope indicates that as the independent variable (usually the x-axis) increases, the dependent variable (y-axis) decreases. A line with a negative slope is straight, and its steepness depends on the absolute value of the slope a. Thus, the line goes down and to the left.

[tex]A=x^2[/tex]
( Since the base is in the shape of a square and we know that the area of square with side length s is given as:
[tex]Area=s^2[/tex] )
So, the volume of the pyramid is calculated as:
[tex]V=\dfrac{1}{3}\times (x^2\times 9)\\\\V=3x^2 \ cm^3[/tex]
Hence, the volume of pyramid is:
3x^2 cm^3
A pyramid is a solid shape with several triangles and a base. The volume of the pyramid in terms of x is 3x^2 cm3
How to calculate the volume of a pyramid?The volume(V) of an oblique square pyramid with height 'h' and base area A is expressed according to the formula:
V = Bh/3

the first term of the sequence is 13 the term to rule is take away -5 work out the 4th term
The student is trying to find the 4th term in a mathematical sequence where the first term is 13 and the rule for each term is to add 5. Thus, the 4th term of this sequence is 28.
Explanation:The student is asking about a mathematical sequence where the first term is 13 and the term to rule is 'take away -5', or in other words, add 5 (since subtracting a negative number is the same as addition). So, to find the nth term of this sequence, you subtract (or add in this case) -5 to the first term, and continue in the sequent term.
Using these rules, here are the first four terms of the sequence: 1st term - 13. 2nd term [tex]- 13 + 5 = 18[/tex]. 3rd term [tex]- 18 + 5 = 23[/tex]. 4th term[tex]- 23 + 5 = 28.[/tex]

Determine the equation of the graph and select the correct answer below.
parabolic function going down from the left and turning at the point negative three comma two and going up through the point zero comma twelve and continuing towards infinity
y = (x + 3)2 − 2
y = (x − 3)2 − 2
y = (x + 3)2 + 2
y = (x − 3)2 + 2
Answer:
The correct answer is [tex]y = \frac{10}{9}(x+3)^2+2[/tex]
Step-by-step explanation:
The correct answer to the question is not provided in the options listed below.
In order to find the equation of the quadratic function that you're looking for, you should identify the two points the parabola passes through: the vertex (that is point (-3,2)) and the y-intercept (the point (0,12)).
As we are given the vertex of the quadratic function, we can use the completed square form: [tex]y=a(x-h)^2+k[/tex], where h and k are, respectively, the x and y coordinates of the vertex.
As (-3,2) is the vertex, we have:
[tex]y=a(x+3)^2+2[/tex]
Now, as the graph passes through the point (0,12), we can replace x=0 and y=12 in the formula above in order to find the value of a. Then, we make a the subject of the equation:
[tex]12=a(0+3)^2+2[/tex]
[tex]12=9a+2[/tex]
[tex] 10=9a[/tex]
[tex] \frac{10}{9}=a[/tex]
So, the equation of the parabola is [tex]y=\frac{10}{9}(x+3)^2+2[/tex].
A hotel chain charges $75 each night for the first two nights and $50 for each additional night’s stay. the total cost t is a function of the number of nights x that a guest stays.
you would need a function to determine whether to use a formula for 1 or 2 nights or a formula for more than 2 nights
T(x)={a if x <_ 2, b if x > 2}
if it's 2 nights or less use option a, a = 75x
if its longer than 2 days use option b, b= 50x + 50
Answer:
t = 75x {x ≤ 2}
t = 150 + 50x {x > 2}
Step-by-step explanation:
A hotel chain charges $75 per night for first two nights.
If the number of nights of the stay are x then charges for x nights
= 75x where x ≤ 2
If the stay is for than 2 nights then charges for x nights
= Charges for two first 2 nights(@$75 per night) + charges for other than initial 2 nights (@$50 per night)
= (75×2) + 50x where x > 2
Therefore total cost of the hotel if represented by t then the function will be
t = 75x {x ≤ 2}
t = 150 + 50x {x > 2}
