Hannah says that 2.11 is a rational number. Gus says that 2.11 is a repeating decimal.

Answers

Answer:

Yes, she is correct.

Step-by-step explanation:

A real number that can be expressed as [tex]\frac{p}{q}[/tex],

Where,

p and q are integers,

Such that, q ≠ 0,

is called a rational number.

A terminating decimal is always a rational number,

Thus, 2.11 is a rational number,

Verification :

2.11 = [tex]\frac{211}{100}[/tex]

Where,    

Both 211 and 100 are integers,

Such that 100 ≠ 0.

The value 2.11 is a rational number and not a repeating decimal.

Given the number 2.11 ;

Rational numbers Can be expressed in the form p/q ; where q ≠ 0.

However, irrational numbers cannot be be expressed in the form p/q.

2.11 is written into two decimal places ; therefore it can be expressed thus ;

(2.11 × 100) ÷ 100 [tex] \frac{211}{100} [/tex]

[tex]since \: 2.11 = \frac{211}{100} [/tex]

Then, we can conclude that 2.11 is a rational number

What is unitary method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

3/8 of his supply of raisins to make regular trail mix and 1/4 of his supply to make spicy trail mix.

Clint uses 20 pounds of raisins

amount of raisin at the begining

= 1/4 x 20 + 3/8

= 5 + 3/8

= 40/8 + 3/8

= 43/8 pounds

Hence, the amount of raisins at the beginning is 43/8 pounds.

On the first day of school, the school bookstore sold 348 notebooks, some at 25¢ each and the rest at 38¢ each. The total amount of money paid for the notebooks was $100.91. How many of each kind were sold?

Answers

241 of the 25¢ notebook 107 of the 38¢ notebook 1) Let x = no. of 25¢ notebooks sold and y = no. of 38¢ notebooks sold 2) Total notebooks sold: x + y = 348 3) Revenue from the notebooks: 0.25x + 0.38y = 100.91 4) Substitute one equation to the other and solve for a single variable (either x or y)

Final answer:

The bookstore sold 107 notebooks at 38¢ each and 241 notebooks at 25¢ each. A system of equations was used to determine the number of each notebook sold.

Explanation:

Let's denote the number of notebooks sold at 25¢ each as [tex]x[/tex] and the number of notebooks sold at 38¢ each as [tex]y[/tex] .

We are given two pieces of information:

The total number of notebooks sold is [tex]348: x + y = 348[/tex]The total amount of money collected is [tex]$100.91: 0.25x + 0.38y = 100.91[/tex]

We can set up a system of two equations to represent this information:

[tex]x+ y = 348[/tex]                       (Equation 1)

[tex]0.25x + 0.38y = 100.91[/tex]      (Equation 2)

Now, we can solve this system of equations to find the values of x and y.

Multiply Equation 1 by 0.25 to make the coefficients of x in both equations the same:

[tex]0.25x + 0.25y = 87[/tex]             (Equation 3)

​Now, subtract Equation 3 from Equation 2 to eliminate [tex]x[/tex] :

[tex]( 0.25x + 0.38y ) - ( 0.25x +0.25 y) = 100.91 - 87[/tex]

[tex]0.13 y = 13.91[/tex]

[tex]y = 107[/tex]

Now that we have the value for  y, substitute it back into Equation 1 to find  x:

[tex]x + 107 = 348[/tex]

[tex]x = 241[/tex]

Hence , the solution is  x = 241 and y = 107, meaning 241 notebooks were sold at 25¢ each and 107 notebooks were sold at 38¢ each.

Answer:

The average speed of the runner is 7 miles per hour.

Step-by-step explanation:

Given:

Distance ran by [tex]2\frac{ 1}{3} miles[/tex]

Time taken  by the runner = 20 minutes.

To find:

The average speed of a runner=?

Solution:

Now, we know that ,

distance = speed x time

Then, [tex]2\frac{ 1}{3} miles[/tex] = average speed x 20 minutes  

=> average speed = [tex]\frac{(2 \frac{1}{3} miles)}{(20 minutes)}[/tex]

=> average speed = [tex](\frac{(2 x 3 + 1)}{3} miles)}{(20\times\frac{1}{60} hours)[/tex]

=> average speed=[tex]\frac{(\frac{(6+1)}{3})}{(\frac{20}{60})}[/tex]

=> average speed = [tex]\frac{ (\frac{7}{3})}{(\frac{1}{3})}[/tex]

=>average speed = [tex]\frac{7}{3}\times\frac{3}{1}[/tex]

=>average speed = 7

The budget for a film production includes the following employee pay scales: $15,000 for each technical crew member (e.g. camera, lighting, sound), and $10,000 for each support staff (e.g., drivers, craft services, production assistants). A minimum of 20 employees is needed, but the locations can accommodate a maximum of 50 people. There must be at least 12 technical crew members to shoot the film, and there must be at least half as many crew members as support staff. Which combination of employees will minimize the cost, and what is the minimum feasible cost?

Answers

Final answer:

The minimum cost combination of film production employees is 12 technical crew members and 24 support staff members, with a minimum feasible cost of $420,000.

Explanation:

To determine the combination of employees that will minimize the cost, let's set up variables for technical crew members (T) and support staff members (S).

The pay scales are $15,000 for each technical crew member (T) and $10,000 for each support staff member (S).

The objective is to minimize the cost C, where C = 15,000T + 10,000S.

From the constraints provided:

There must be a minimum of 20 employees: T + S ≥ 20.The maximum number of people that can be employed is 50: T + S ≤ 50.There must be at least 12 technical crew members: T ≥ 12.There must be at least half as many crew members as support staff: T ≥ 0.5S.

To minimize the cost while satisfying all constraints, we should aim to hire as few technical crew members as possible, given they are more expensive.

If T = 12 (the minimum), we can solve for S using T ≥ 0.5S, which gives us S ≥ 24.

However, S must be even due to the constraint T ≥ 0.5S and hence we can set S = 24 as a candidate solution, resulting in the minimum number of employees (12 + 24 = 36).

We also need to ensure that S ≤ 2T to satisfy the condition T ≥ 0.5S; with T = 12, the maximum S can be is 24.

The minimum feasible cost is determined by plugging T = 12 and S = 24 into the cost equation:

C = 15,000(12) + 10,000(24) = 180,000 + 240,000 = $420,000.

x/6-x/7=ab

Answers

Final answer:

To solve x/6 - x/7 = ab, find the common denominator, simplify, and then isolate x by multiplying both sides of the equation by the common denominator. The solution is x = 42ab. Always check your answer to ensure it satisfies the original equation.

Explanation:

To solve the equation x/6 - x/7 = ab, one must find a common denominator for the fractions. In this case, the common denominator is 42 because 6 and 7 are both factors of 42. By converting both fractions to have the denominator of 42, we have:(7x/42) - (6x/42) = ab

This simplifies to x/42 = ab, since 7x - 6x is x. Now, multiply both sides by 42 to get x = 42ab.

If we want to solve the equation for a variable other than x, such as y, we might need to return b to denominator status, which implies that we need to divide both sides by b if b represents a multiplication factor for y.

It's also important to confirm that our manipulations haven't altered the value of the equation, which can be done by checking the answer at the end to ensure it is reasonable and satisfies the original equation.

a pineapple drink contains 15% pineapple juice. how much pure pineapple juice should be added to 8 quarts of the pineapple drink to obtain a mixture containing 50% pineapple juice

Answers

5.6 quarts
Hope this helps :)

To solve the problem, set up an equation based on the given information to find the amount of pure pineapple juice needed to obtain a 50% mixture.

To solve this problem, we need to set up an equation based on the given information.

Let x be the amount of pure pineapple juice to be added.

The initial amount of pineapple juice in the drink is 15% of 8 quarts, which is 0.15 * 8 = 1.2 quarts.

After adding x quarts of pure pineapple juice, the total volume of the mixture becomes 8 + x quarts.

Setting up the equation: 1.2 + x = 0.5 * (8 + x).

Solving for x gives the amount of pure pineapple juice needed to obtain a 50% mixture.

your computer supply store sells two types of laser printers. the first type, a, costs $137 and you make a $50 profit on each one. the second type, b, costs $110 and you make a $40 profit on each one. you expect to sell at least 100 laser printers this month and you need you make at least $4400 profit on them. if you must order at least one of each type if printer, how many of each type of printer should you order if you want to minimize your cost?

Answers

Let the number of units of the first type be x and the number of units of the second type be y.

A. You expect to sell at least 100 printers this month. This means that:
A + B >= 100 
For simplicity, we will work on the equal sign (A + B = 100) which is the minimum number of units to be sold.
This can be rewritten as: A = 100 - B .................> equation I

B. You expect to make a minimum profit of 4400. This means that:
50A + 40B >= 4400
Again for simplicity, we will work on the equal sign (50A + 40B = 4400) which is the minimum profit to be made
50A + 40B = 4400 ..................> equation II

Substitute with equation I in II:
50 (100-B) + 40B = 4400
5000 - 50B + 40B = 4400
5000 - 4400 = 50B - 40B
600 = 10B
B = 60
Substitute in equation I:
A = 100 - B = 100-60 = 40

Therefore, to minimize your cost and achieve your goals in number of selling units and profits:
you should buy at least 40 units from the first type and 60 units from the second type

Brandon rode his bike 90% of the distance that Carlee did this week. He rode 58.5 miles. How many miles did Carlee ride?

Answers

Carlee rode 65 miles
Final answer:

To find out how many miles Carlee rode, you need to divide the distance Brandon rode (58.5 miles) by 0.9 (representing 90%). The result is that Carlee rode 65 miles.

Explanation:

The problem requires you to determine the distance that Carlee biked based on the information provided. Given that Brandon rode his bike 90% of the distance Carlee did, and he rode 58.5 miles, to calculate the distance Carlee traveled, you would divide the distance Brandon rode by 0.9 (which represents 90%).

So, the calculation would be: 58.5 ÷ 0.9 = 65.

Therefore, Carlee must have biked 65 miles in total given the information provided.

A figure skater needs a total score of at least 90 to move on to the next round. Her total score is the average of four judges’ scores. The first three judges’ scores were 83, 88, and 92. The figure skater found out she made it to the next round.

What is the minimum score the fourth judge could have given her?

Answers

To get the answer to this question is,
(83 + 88 + 92 + x) / 4 > = 90
(263 + x) / 4 > = 90....Multiply both of sides by 4, then eliminating the 4 on the left.
263 + x > = 90 * 4
263 + x > = 360
x > = 360 - 263
x > = 97
So, the minimum score would be '97' for your answer.

Answer-
5,4,3
Final answer:

The term 'perfect trios' as a whole number is not a standard mathematical term, but it may refer to something like Pythagorean triples, which are sets of three positive integers that satisfy the equation a² + b² = c². Without additional context, the term remains unclear.

Explanation:

The term "perfect trios" is not a standard mathematical term, so it is a bit unclear what it refers to. It may be a term used in a specific textbook or class to refer to a certain type of number trio or to phenomena in physics or another field. However, in mathematics, we can talk about perfect numbers, which are positive integers that are equal to the sum of their proper divisors (excluding the number itself). Additionally, we may consider Pythagorean triples, which are sets of three positive integers a, b, and c, such that a² + b² = c². These are special cases of perfect squares and can be considered when discussing whole number trios in a mathematical sense.

Without more context, we can assume that 'perfect trios' might be an informal term for sets of three numbers that have some special property, such as those that make up a Pythagorean triple.

For example, the Pythagorean triple (3, 4, 5) is well-known because 3² + 4² = 5². Similarly, (5, 12, 13) is another Pythagorean triple as 5² + 12² = 13².
