Need help answering this question tysm! (Picture attached)

The correct choices B, C, and D all represent the equation that Conner scored 25% more points than Max, using algebraic terms to demonstrate this proportional increase. Choices B and C show the total score as a multiple of Max's score, while D adds an extra 25% to Max's score.

The problem presented is an algebraic representation of a proportional relationship. Given that Conner scored 25% more points than Max, we can express this relationship in different but equivalent equations. Choices B, C, and D effectively communicate that Conner's score, c, is increased by 25% more than Max's score, m.

Choice B is written as c = (1 + 0.25)m, which represents a 100% (which is 1 in decimal form) of Max's score plus an additional 25%. Choice C simplifies this to c = 1.25m, which is another way to represent a 25% increase on Max's score. Choice D is expressed as c = m + 0.25m which sums Max's score with another 25% of it. Each of these equations correctly translates the scenario into a mathematical expression.

Answer:

1) The values of 'a' and 'b' are [tex]$ \frac{3}{4} $[/tex] and [tex]$ \frac{3}{4} $[/tex] respectively.

2) The values of 'a' and 'b' are '3' and '-3' respectively.

Step-by-step explanation:

1) Given: [tex]$ \frac{3x}{(x - 2)(3x + 2)} = \frac{a}{x - 2} + \frac{b}{3x + 2} $[/tex]

We solve this by partial fraction method.

Taking LCM in the RHS we get,

[tex]$ \frac{3x}{(x - 2)(3x + 2)} = \frac{a(3x + 2) + b(x - 2)}{(x - 2)(3x + 2)} $[/tex]

[tex]$ \implies 3x = a(3x + 2) + b(x - 2) $[/tex]

To find the value of 'a', substitute x = 2. This would make 'b' vanish leaving an equation with 'a'.

[tex]$ \therefore 3(2) = a(3.2 + 2) + b (2 - 2) \implies 6 = a(8) $[/tex]

[tex]$ \implies a = \frac{-2}{3} $[/tex]

Now, Substitute [tex]$ x = \frac{-2}{3} $[/tex] to solve for 'b'.

[tex]$ \implies 3(\frac{-2}{3}) = a (3.\frac{-2}{3} + 2) + b(\frac{-2}{3} -2) $[/tex]

[tex]$ \implies -2 = b \frac{-8}{3} $[/tex]

[tex]$ \implies b = \frac{3}{4} $[/tex]

Therefore, a = [tex]$ \frac{3}{4} $[/tex] and b = [tex]$ \frac{3}{4} $[/tex]

2) Given [tex]$ \frac{3}{x^2 - 5x + 6} = \frac{a}{x - 2} + \frac{b}{x - 3} $[/tex]

We follow the same procedure as (1).

Taking LCM we get

[tex]$ \frac{3}{x^2 - 5x + 6} = \frac{a (x - 3) + b(x - 2)}{(x^2 - 5x + 6)} $[/tex]

[tex]$ \implies 3 = a(x - 3) + b(x - 2) $[/tex]

Substituting x = 2, we get:

3 = a(-1) [tex]$ \implies a = -3 $[/tex]

Also, Substituting x = 3, we get:

3 = b(1)

[tex]$ \implies b = 1 $[/tex]

Therefore, the values of a and b are -1 and 1 respectively.

Answer:

2462.4 square inches

Step-by-step explanation:

To find the length of the longer wall use the following ratio and solve for x.

x/36= 4.75/ 2.5

x= 68.4

Area of a rectangle = l(w)

68.4(36)= 2462.4 square inches

The area of the wall is the product of its dimension.

The area of the actual wall is  2462.4 square inches

The scale is given as:

[tex]\mathbf{Scale = 4.75 : 2.5}[/tex]

The shorter side of the actual wall is 36 inches.

So, we have:

[tex]\mathbf{Long : 36= 4.75 : 2.5}[/tex]

Express as fractions:

[tex]\mathbf{\frac{Long }{36}= \frac{4.75 }{ 2.5}}[/tex]

Multiply both sides by 36

[tex]\mathbf{Long= 36 \times \frac{4.75 }{ 2.5}}[/tex]

[tex]\mathbf{Long= 68.4}[/tex]

So, we have:

[tex]\mathbf{Long= 68.4}[/tex]

[tex]\mathbf{Short= 36}[/tex]

The area is then calculated as:

[tex]\mathbf{Area = 68.4 \times 36}[/tex]

[tex]\mathbf{Area = 2462.4in^2}[/tex]

Hence, the area of the actual wall is  2462.4 square inches

Step-by-step explanation:

Function and its graphs

Part A

The graph shown in the image corresponds to a cubic function because of its classical infinite branches, three real roots and two extrema values

Part B

Knowing the value of the three roots x=-20, x=-5, and x=15 we can express the cubic function in factored form:

[tex]F(x)=C(x+20)(x+5)(x-15)[/tex]

The value of C will be determined by using any particular point from the graph. Let's use (0,1)

[tex]1=C(0+20)(0+5)(0-15)[/tex]

[tex]C=-\frac{1}{1500}[/tex]

Replacing, we find the factored form of the function

[tex]F(x)=-\frac{1}{1500}(x+20)(x+5)(x-15)[/tex]

The standard form demands to expand all the products and simplify

[tex]F(x)=-\frac{1}{1500}(x^3+10x^2-275x-1500)[/tex]

When mack babysits, he charges $12 an hour plus bus fare. The amount mack is paid depends on the number of hours he babysits.

1. If mack babysits for 1 hour and the bus fare is $2.50, how much will mack be paid?

2. If mack babysits for 4 hours and the bus fare is $2.50, how much will mack be paid?

Answer:

1. Total Amount mack will be paid for 1 hour is $14.50.

2. Total Amount mack will be paid for 4 hours is $50.50.

Step-by-step explanation:

Given:

Charges of mack for 1 hour = $12

bus fare = $2.50

We will fist find for part 1.

1) Given:

Number of Hours= 1

Charges of mack for 1 hour = $12

bus fare = $2.50

we need to find the amount he get paid for it can be calculated by Multiplying Charges of mack for 1 hour with number of hours and then adding bus fare

Total amount he will get paid = Charges of mack for 1 hour × Number of Hours + Bus fare = [tex]\$12\times 1 +\$2.50= \$14.50[/tex]

Hence, Total Amount mack will be paid for 1 hour is $14.50.

Now we will find for part 2.

2) Given:

Number of Hours= 4

Charges of mack for 1 hour = $12

bus fare = $2.50

we need to find the amount he get paid for it can be calculated by Multiplying Charges of mack for 4 hour with number of hours and then adding bus fare

Total amount he will get paid = Charges of mack for 1 hour × Number of Hours + Bus fare = [tex]\$12\times 4 +\$2.50= \$50.50[/tex]

Hence, Total Amount mack will be paid for 4 hour is $14.50.

Step-by-step explanation:

100-65=35

35/1.16= 30.1724

30.1724/1.5=20.1149

You can't feed a .1149 of a person so 20 people

Given the maximum budget and cost per pound, the largest turkey you can purchase is approximately 30.17 pounds. This will feed about 20 guests, considering each person consumes 1.5 pounds of turkey.

The subject of this question is mathematics, specifically, problem-solving involving budgets and limits. Given that the maximum budget for this dinner is $100 and the fixed costs total to $65, we're left with $35 for the turkey. Each pound of turkey is priced at $1.16.

By dividing the remaining amount of money (which is $35) by the cost per pound of turkey (which is $1.16), we compute the total pounds of turkey we can afford. That is, $35 / $1.16 = approximately 30.17 pounds.

Each guest requires 1.5 pounds of turkey, so we now calculate how many guests can be fed by this amount of turkey. We do this by dividing the total pounds of turkey (30.17 pounds) by the amount required per guest (1.5 pounds), which gives us 30.17 / 1.5 = approximately 20.11. Since you can't invite a fraction of a person, the largest size turkey you can afford can feed about 20 people.

Answer:

18 pieces are needed

Step-by-step explanation:

Edgings are put all around the rectangular flower garden. So we need to know the perimeter (sum of all sides) of the rectangle. The formula is:

Perimeter of Rectangle = 2(Length + Width)

Given,

Length = 15

Width = 12

So,

Perimeter = 2(Length + Width)

Perimeter = 2(15 + 12)

Perimeter = 2(27)

Perimeter = 54

So, we need to cover 54 feet. Each edging is 3 feet in length, so 54 feet will be covered by:

54/3 = 18 edgings

Answer:

The length of the first banner = 8 ft

The length of the second banner = 12  ft

The length of the third banner  = 16 ft

Step-by-step explanation:

The total length of the banner material = 36 ft

Now, let us assume the length of the first banner  = k ft

So, the length of the second banner  = First banner + 4 ft = ( k + 4) ft

The length of the third banner = Second banner  + 4 ft  = [( k + 4) + 4]  ft

Now, according to the question:

The length of ( First  + Second + Third) banner  = 36 ft

⇒ (k) + (k +4) + (k + 8)  = 36

or, 3 k = 36 - 12= 24

or, k = 24/3  = 8

⇒ k = 8 ft

So, the length of the first banner = k = 8 ft

The length of the second banner = k + 4 = 8 + 4 = 12  ft

The length of the third banner = k + 4 + 4  = 8 + 8 =  16 ft

Answer: 1. 210 meters per second .

2.  756  kilometers per hour.

Step-by-step explanation:

Given : The formula [tex]S(d)=\sqrt{9.8d}[/tex] to calculate the estimated speed, in meters per second of a tsunami.

1. If the disturbance occurred at an ocean depth of 4,500 meters.

Then put d= 4500 in the above formula , we get

[tex]S(d)=\sqrt{9.8\times4500}[/tex]

[tex]S(d)=\sqrt{44100}=\sqrt{21\times21\times10\times10}\\\\=\sqrt{210^2}=210[/tex]

Hence, if the disturbance occurred at an ocean depth of 4,500 meters , the estimated speed would be 210 meters per second .

Also, A meter per second is equal to 3.6 kilometers per hour.

i.e. 1 meter per second = 3.6 kilometers per hour

Then by unitary method ,

210 meters per second  =[tex]3.6\times210[/tex] kilometers per hour

=756  kilometers per hour.

The weight of crate when it has 19 bricks is 165 pounds

Given that, A crate with 20 bricks weighs 167 pounds.  

When the same crate has 32 bricks, it weighs 191 pounds.  

Now, let the weight of each brick be "m" pounds and weight of the crate be 'n" pounds.

Then, when crate has 20 bricks

Total weight = weight of bricks + weight of crate

[tex]167 \text { pounds }=\text { number of bricks } \times \text { weight of each brick }+\text { weight of crate }[/tex]

[tex]167=20 \times m+n[/tex]

20m + n = 167 ----- eqn (1)

Now, when crate has 32 bricks

Total weight = weight of bricks + weight of crate

[tex]191 \text { pounds }=\text { number of bricks } \times \text { weight of each brick + weight of crate }[/tex]

[tex]191=32 \times m+n[/tex]

32m + n = 191 ----- eqn (2)

Now, subtract (1) from (2)

32m + n = 191

20m + n = 167

(-) ----------------

12m + 0 = 24

m = 2

Then, from eqn (1)  

20(2) + n = 167  

40 + n = 167  

n = 167 – 40 = 127

Now, when the box has 19 bricks

Total weight = 19 bricks x 2 pounds per brick + 127 pounds of crate

[tex]\text { Total weight }=19 \times 2+127=38+127=165[/tex]

Hence, the weight of crate when it has 19 bricks is 165 pounds.

Final answer:

The solution to the inequality -2x ≤ -10 is found by dividing both sides by -2 and reversing the inequality sign, resulting in C) x ≥ 5.

Explanation:

The expression that represents the solution to -2x ≤ -10 is found by dividing both sides of the inequality by -2. When dividing by a negative number, we must reverse the inequality symbol. Thus, dividing both sides by -2 would give us x ≤ 5. However, since the inequality symbol was reversed, the correct solution is x ≥ 5.

Here are the steps broken down:

Starting with -2x ≤ -10.

Dividing both sides by -2 gives x ≥ 5.

Therefore, the correct answer is C) x ≥ 5.
