Answer:

16 cm

Step-by-step explanation:

Let the width be x

The length will be 3 x since the length is three times the width

Perimeter=2(l+w) where l is length and w is width

By substituting 128 cm for perimeter, x for w and 3 x for l then

128=2(3x+x)

128=8x

[tex]x=\frac {128}{8}=16[/tex]

Therefore, the width is 16 cm, the width is 16*3=48 cm

The correct answer is:

The greatest possible width for the rectangle, with length three times, is 16 cm, ensuring the perimeter doesn't exceed 128 cm.

Let's denote:

- Width of the rectangle as [tex]\( w \)[/tex] cm

- Length of the rectangle as [tex]\( 3w \)[/tex] cm (since it is three times the width)

The perimeter of a rectangle is given by:

[tex]\[ \text{Perimeter} = 2 \times (\text{Length} + \text{Width}) \][/tex]

Given the perimeter is at most 128 cm, we can write:

[tex]\[ 2 \times (3w + w) \leq 128 \][/tex]

Now, let's solve for [tex]\( w \)[/tex]:

[tex]\[ 2 \times (3w + w) \leq 128 \]\[ 2 \times 4w \leq 128 \]\[ 8w \leq 128 \]\[ w \leq \frac{128}{8} \]\[ w \leq 16 \][/tex]

So, the width of the rectangle must be less than or equal to 16 cm. Therefore, the greatest possible value for the width is 16 cm.

Answer:

6.5 yards total

Step-by-step explanation:

1.

Find the least common multiple (LCM) for the denominators. Because you have to make the denominators the same before you add the fractions, find a common multiple that they share. Then choose the lowest one. In this case the LCM is 6

2. Multiply the numerator and denominator to get like denominators. You'll need to multiply the entire fraction to make the denominator become the least common multiple. In this case multiply 2/3 by 2 = 4/6

3. Add the two fractions and the whole numbers

In this case: 2+ 3 =5

4/6 + 5/6 = 9/6

4. Now you have

5 + 9/6

5. Simplify 9/6 to 1 3/6 = 1 1/2

6. Add 5 + 1 1/2 = 6 1/2

Kristin has approximately 4 yards of plaid ribbon and 3 yards of polka-dot ribbon after rounding fractions to the nearest whole number, which totals to about 7 yards of ribbon in all. This estimation method is reasonable for handling fractions.

We are asked to estimate the total amount of ribbon Kristin has by adding together 3 2/3 yards of plaid ribbon and 2 5/6 yards of polka-dot ribbon. To estimate, we round each fraction to the nearest whole number. The 2/3 in 3 2/3 rounds up to 1, making it approximately 4 yards. The 5/6 in 2 5/6 rounds up to 1, making it approximately 3 yards. Adding these estimates together gives us 4 yards of plaid ribbon plus 3 yards of polka-dot ribbon, which equals to about 7 yards of ribbon in total.

Our estimate is reasonable because we rounded each fraction up to the nearest whole number, making for easy addition. It's also a common method to simplify calculations and get a sense for the magnitude of the sum. Since our original fractions were more than 1/2 (3/2 is 1 1/2, and 5/6 is nearly 1), rounding up provides a reasonable overestimate likely very close to the actual sum.

Step-by-step explanation:

we have

[tex]y=\sqrt{-x-3}[/tex]

we know that

The radicand must be greater than or equal to zero

so

[tex](-x-3)\geq 0[/tex]

solve for x

Adds 3 both sides

[tex]-x\geq 0+3[/tex]

[tex]-x\geq 3[/tex]

Multiply by -1 both sides

Remember that, when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

[tex]x\leq -3[/tex]

so

The domain of the function is the interval (-∞,-3]

Answer:22/18 or 1 4/15

First, you have to find out how many pieces were eaten in all. This could be done with addition. 1/5+1/3= (3/15+5/15)= 8/15

Lastly, you have to find out how much they ate from 15 pieces. This could be done with subtraction. Since 15 is a whole number, the fraction for it would be 15/1. 15/1-8/15=(30/15-8/15)=22/18 or 1 4/15

Answer: It is the same distance from zero as the number she tells you.

Step-by-step explanation:

For this exercise it is important to remember the definition of opposite numbers.

Opposite numbers are defined as those numbers that are in opposite positions on a number line, but their distance from zero is the same. Then, one of them is positive and the other one is negative.

The sum of opposite numbers is zero.

For example, the following numbers are opposite:

 [tex]8[/tex] and [tex]-8[/tex]

 [tex]31[/tex] and [tex]-31[/tex]

 [tex]105[/tex] and [tex]-105[/tex]

Therefore, if Shanika says the opposite of a rational number, you can conclude that the number she is thinking is the same distance from zero as the number she tells you.

It is the same distance from zero as the number she tells you.

Answer:

C. Select a number from {1, 2, 3, 4, 5, 6} and a vowel.

Step-by-step explanation:

Let's start this with a simple example: how many messages are possible using one number from {7, 9} and one letter from {a, b}. It will be 4 as 7a, 7b, 9a and  9b. This result can also come by multiplying the number of digits used and number of alphabets used - here number of digits are 2 (they are 7 and 9) and number of alphabets used are 2 (they are 'a' and 'b'). So 2 × 2 = 4.

[NOTE : In this question 7a and a7 are same]

Maximum number of options consists of vowels as letters so we will first find the number of digits needed if vowels are used as letters.

The number of vowels are 5 (they are 'a', 'e', 'i', 'o', 'u').

The number of possible precodes needed = 30

Let the number of digits needed be 'n'.

Then n × 5 = 30

∴ n = 6

Therefore the number of digits needed is 6 which is there in option C. The digits are {1, 2, 3, 4, 5, 6}

Therefore option C is the answer.

Step-by-step explanation:

To find the composition of two functions F(G(x)), substitute the value of G(x) into F(x). The result for F(G(x)) in this case is -10x + 38.

This question pertains to the mathematical concept of functions. Specifically, you are being asked to find the composition of two functions, F(x) and G(x).

To find F(G(x)), you substitute the value of G(x) into the function F(x). Recall that G(x) = -2x + 9. So, you need to replace 'x' in F(x) = 5x -7 by the value of G(x). Thus, F(G(x)) = 5(-2x+9) - 7 = -10x + 45 - 7 = -10x + 38.

Answer:

32≤x≤48 is the best estimate for the amount of money, x, that Erika has to pay to get to her destination. Hence, option D is correct.

Step-by-step Explanation:

Information Fetching and Solution Steps

As Erika estimates that she is 200 to 300 miles away from her destination, and car travels 25 miles per gallon of gas. So,

        i.e 200/25 = 8 gallons.

        As cost of each gallon being $4.00.

        So, 8 × 4 = 32$ is the amount she needed to make 200 miles.

        i.e 300/25 = 12 gallons.

        As cost of each gallon being $4.00.

        So, 12 × 4 = 48$ is the amount she needed to make 300 miles.

From the above calculation, we observe that 32$ and 48$ is the best estimate between 200 miles and 300 miles.

Therefore, 32≤x≤48 is the best estimate for the amount of money, x, that Erika has to pay to get to her destination. Hence, option D is correct.

Answer:

Consultant B offers the cheapest price for a five hour session.

Hence, B. Consultant B is the correct option.

Step-by-step Explanation:

Analyzing the offer price of Consultant A, B and C for a Five hour session:

So, for five hour session, Consultant A is offering the price:

$160 + $75 + $75 + $75 + $75 = $460

So, for five hour session, Consultant B is offering the price:

$90 + $90 + $90 + $90 + $90 = 450 US$

So, for five hour session, Consultant C is offering the price:

$140 + $80 + $80 + $80 + $80 = $460

Comparing the price offers of Consultant A, B and C

So, by comparing the price offers of Consultant A, B and C, we determine that:

So, from this comparison, we conclude that Consultant B offers the cheapest price for a five hour session.

Hence, B. Consultant B is the correct option.

                             Question # 3 Solution

Answer:

They spent 4 nights at the hotel. Hence, option B is correct.

Step-by-step Explanation:

To determine:

how many nights did they stay at the hotel?

Information Fetching and Solution Steps

As the total amount they spent = $1,200

As $75 is the service charges as Jessica and Ashely purchased full room service for every night.

Per night charges = hotel chargers + service charges

Per night charges = $225 + $75 ⇒ $300

So, total nights will be calculated as:

Total nights = total amount they spent ÷ Per night charges

Total nights = $1,200 ÷ $300 ⇒ 4 nights

Therefore, they spent 4 nights at the hotel. Hence, option B is correct.

                                 Question # 4 Solution

Answer:

Hence, |h − 57.5| ≤ 7.5 is the absolute values which best represents this restriction, where ( h ) represents height. Hence, option A is correct.

Information Fetching and Solution Steps

Let us take the equation of following absolute value:

|h − 57.5| ≤ 7.5

We know h − 57.5 ≤ and h − 57.5 ≥ −50

h − 57.5 ≤ 7.5         (Condition 1)

h − 57.5 + 57.5 ≤ 7.5 + 57.5      (Add 57.5 to both sides)

h ≤ 65

h − 57.5 ≥ −7.5         (Condition 2)

h − 57.5 + 57.5 ≥ −7.5 + 57.5     (Add 57.5 to both sides)

h ≥ 50

So, h ≤ 65 and h ≥ 50

Solution Graph is also attached as shown in attached figure a.

Hence, |h − 57.5| ≤ 7.5 is the absolute values which best represents this restriction, where ( h ) represents height. Hence, option A is correct.

Using same methodology we observe that all other options B, C, and D brings wrong values which is as follows:

Hence, from all discussion, we conclude that |h − 57.5| ≤ 7.5 is the absolute values which best represents this restriction, where ( h ) represents height, as it brings h ≤ 65 and h ≥ 50. Hence, option A is correct.

Answer:

279J is the total amount of gravitational potential  energy gained by the box.

Step-by-step explanation:

Note: As you missed to add the diagram. So, I found and have attached the diagram as shown in figure a which is attached below, based on which I am answering your question. Hopefully, it would help understand the concept.

The energy stored in an object near the surface of the Earth due of its state in a gravitational field is termed as Gravitational potential energy.

The formula to get gravitational potential energy: [tex]Ep_}=mgh[/tex]

Here,

m = mass of the object normally measured in kg

g =  gravitational acceleration having constant value as 9.8 m/s²

h = height in m

As from the diagram a, we observe that object carries 155-newton force and at point B, the height is 1.80 m, as shown in figure a.

So,

      F = 155 N

      h = 1.80 m

From F = mg, we can get the mass of  object

       F = mg        ∵ g =  gravitational acceleration

      m = F/g

      m = 155/9.8 ⇒ m = 15.81

The gravitational potential energy is measured in joule which is abbreviated as 'J'.

The formula to get gravitational potential energy:

[tex]Ep_}=mgh[/tex]

[tex]Ep_}=(15.81)(9.8)(1.80)[/tex]

[tex]Ep_}=278.88J[/tex]  ≈ [tex]279J[/tex]

Therefore, 279J is the total amount of gravitational potential  energy gained by the box.

Answer:

10 rectangles can fit in the square that has one side 10 cm long.

Step-by-step explanation:

Given:

Rectangle 5 cm multiply 2 cm .

Square that has one side 10cm long.

Now, to find the number of rectangle that can fits in the square.

So, for getting the number of rectangle we need to get the area first:

Area of rectangle as given 5 cm multiply 2 cm :

[tex]5\ cm\times 2\ cm=10\ cm^2[/tex]

Then the area of square as given side is 10 cm:

Area of square = (side)²

[tex]Area\ of\ square=10^2[/tex]

[tex]Area\ of\ square=100\ cm^2[/tex]

Now, for getting the number of rectangle we divide the area of square by area of rectangle:

Number of rectangle = Area of square ÷ Area of rectangle

[tex]Number\ of\ rectangle=100\ cm^2\div 10\ cm^2[/tex]

[tex]Number\ of\ rectangle=10.[/tex]

Therefore, 10 rectangles can fit in the square that has one side 10 cm long.

Given that Crystal sold b balloons, Aliya sold 2 more balloons than Crystal and Shamika sold twice as many balloons as Crystal then forming the expressions;

If Crystal sold b number of balloons then;

a) Number of balloons Aliya sold is 2 more than Crystal's .This means Aliya sold two more balloons added to what Crystal sold.mathematically, it will be = 2+b

b) Number of balloons Shamika sold is twice Crystal's.This means Shamika sold double the number of balloons Crystal sold.If Crystal sold b balloons, twice this number is =2b

c)Total number of balloons sold will be presented by the expression;

=b+2+b+2b=4b+2

The expression for total cost will be;

$2*(4b+2) =$900----------------------expression

d) solving the expression for total cost as

   2(4b+2)=900

    8b+4=900

     8b=900-4

     8b=896 -------divide both sides by 8 to get b

    b=896/8 =112 balloons  ----------value of variable b

e)

Crystal sold  b  balloons = 112 balloons

Shamika sold, 2b, =2*112 = 224 balloons

Aliya sold , 2+b balloons = 2+112 =114 balloons

f)By solving the expression for total cost , you obtain the value of variable b which represents the number of balloons sold by Crystal. Using the value of b, you can calculate the number of balloons for Shamika and Aliya using their expressions which represent number of balloons they sold.

The solutions for the inequality y > (1/5)x + 3 exist in Quadrants I and II.

The inequality y > (1/5)x + 3 represents a line with a positive slope of 1/5.

The solutions for this inequality exist in the quadrants where y is greater than the value of (1/5)x + 3.

When x is positive and y is positive, the solutions exist in Quadrant I. When x is negative and y is positive, the solutions exist in Quadrant II.

Since the inequality is y > (1/5)x + 3 and not y >= (1/5)x + 3, the solutions do not exist in Quadrant III or IV where y would be negative.

Final answer:

Georgia received 3 dimes on Tuesday, 9 on Wednesday, and 81 on Thursday, following a trend of tripling the amount each day. Continuing this pattern, she would receive 243 dimes on Friday.

Explanation:

The question involves identifying and extending a mathematical pattern. Here, we notice that the number of dimes Georgia receives each day is being multiplied by 3 to get the number of dimes for the next day. On Tuesday she received 3 dimes, on Wednesday this was multiplied by 3 to get 9 dimes, and on Thursday it was multiplied again by 3 to get 81 dimes. So, to find out how many dimes Georgia received on Friday, we simply continue this pattern and multiply Thursday's amount by 3.

3 dimes (Tuesday) * 3 = 9 dimes (Wednesday

9 dimes (Wednesday) * 3 = 81 dimes (Thursday)

81 dimes (Thursday) * 3 = 243 dimes (Friday)

Therefore, if this trend continued, Georgia would have received 243 dimes on Friday.

[tex]2(2) + \frac{2}{ {2}^{2} } \\ 4 + \frac{2}{4} = 4.5[/tex]

Answer:

2

Step-by-step explanation:

Assuming the function is:

f(x) = (x² − 2) / (x − 1)

Use quotient rule to find the derivative.

f'(x) = [ (x − 1) (2x) − (x² − 2) (1) ] / (x − 1)²

f'(x) = (2x² − 2x − x² + 2) / (x − 1)²

f'(x) = (x² − 2x + 2) / (x − 1)²

Evaluate at x=2.

f'(2) = (2² − 2(2) + 2) / (2 − 1)²

f'(2) = (4 − 4 + 2) / 1

f'(2) = 2
