K.27. This is because if you were to factor a^2-b^2, you get (a+b)(a-b)=648. If you substitute a-b for 24, it would lead the equation to be 24(a+b)=648. Divide 24 from both sides to get the answer.

To find the value of (a+b), substitute a-b into the equation [tex]a^{2} - b^{2} = 648[/tex] and solve for (a+b). The value of (a+b) is 27, i.e., option K.

To find the value of a+b, we can use the formula for the difference of squares: [tex]a^{2} - b^{2} = (a+b)(a-b)[/tex]. Given that a-b = 24, we can substitute this value into the equation. So, we have:
648 = (a+b)(24)
Now, divide both sides of the equation by 24 to isolate (a+b):
(a+b) = 648/24 = 27. Therefore, the value of (a+b) is 27.

A costume designer has 36 bat buttons and 18 black cat buttons she must use to create costumes

To find  the largest number of costumes we take GCF

GCF gives the largest and greatest number of grouping

WE find GCF of 36 and 18

1, 2, 3, 6, 9, 18  are the factors of 18

 1, 2, 3, 4, 6, 9, 12, 18, 36 are the factors of 36

Greatest common factor GCF is 18

So , 18  is the largest number of costumes she can make.

In the expression 300 + 200/x for Alysa's party, the variable 'x' stands for the number of attendees to ensure the party cost stays within the $5.00 per person limit.

In the expression 300 + 200/x, the variable x represents the number of people attending Alysa's sweet sixteen birthday party.

Alysa's mom has set a maximum cost of $5.00 per person, and the total cost for renting the hall is $300, which is a fixed cost. To ensure the party cost does not exceed $5.00 per person, the cost per person is calculated by dividing the additional $200 by the number of attendees (x).

The answer is 90 I believe

Answer:

60 mph

Step-by-step explanation:

Let distance travelled by both the cars equal to d.

Also assume speed of Car A as x and speed of Car B as y

Then using distance formula,

d = 2x

Similarly for car B, d = 1.5 y

Also given that

speed of car B = speed of car A +15

y =x+15

Hence we have 2 x = 1.5 y  Or x =0.75 y

Substitute in y =x+15 :  y =0.75y+15

0.25y = 15

y = 15/0.25 = 60 mph

Speed of car B = 60 mph

Multiply the rows by the number of chairs 40×22= 880

x^2 + y^2 - 2x + 8y - 47 = 0

x^2 + y^2 - 2x + 8y = 47

(x^2 - 2x) + (y^2 + 8y) = 47

(x^2 - 2(1)x) + (y^2 + 2(4)y) = 47

(x^2 - 2(1)x + 1^2) + (y^2 + 2(4)y + 4^2) = 47 + 1^2 + 4^2

(x - 1)^2 + (y + 4)^2 = 64 = 8^2

Answer:

B. f(x) = (x + 3)2 − 6

Step-by-step explanation:

Answer:

[tex]f(x)=(x+3)^2-6[/tex]

Step-by-step explanation:

We have been given a function [tex]f(x)=x^2+6x+3[/tex]. We are asked to find the function equivalent to our given function in vertex form.

To convert our given function in vertex form, we need to complete the square for our given function as:

Add and subtract [tex](\frac{b}{2})^2[/tex] from equation:

[tex](\frac{b}{2})^2=(\frac{6}{2})^=3^2=9[/tex]

[tex]f(x)=(x^2+6x+9)+3-9[/tex]

[tex]f(x)=(x^2+2\cdot 3x+3^2)-6[/tex]

[tex]f(x)=(x+3)^2-6[/tex]

Therefore, the [tex]f(x)=(x+3)^2-6[/tex] is equivalent to our given function in vertex form.

The number that belongs in the green box is 2.

Based on the information provided, which relates to probability and the use of a calculator, we can assume the question pertains to Mathematics, likely within a Middle School curriculum where basic probability and calculator skills are taught.

When dealing with shuffled cards or marbles in a bag, one typically calculates probabilities or expected outcomes

There are a total of eight cards: five green cards and three yellow cards.

Since the cards are well shuffled, the probability of drawing a green card is 5/8.

The probability of drawing a yellow card, in this case, would be 3/8.

Since the green cards are marked with the numbers 1, 2, 3, and 4, the number that belongs in the green box would be 2.

Final answer:

To find the number in the green box, calculate the ratio of green cards to total cards.

Explanation:

The number that belongs in the green box can be found by calculating the ratio of green cards to total cards. In this case, there are 5 green cards out of 8 total cards. To find the number that belongs in the green box, we can use the formula:

Number in green box = green cards / total cards

Number in green box = 5 / 8

Using a calculator or simplifying the fraction, we find that the number in the green box is 5/8 or approximately 0.625.

Distance = √((x2-x1)^2 + (y2-y1)^2)

Distance = √((-1 - 6)^2 + (14 - -16)^2)

Distance = √( -7^2 + 30^2)

Distance = √(49 + 900)

Distance = √949

Distance = 30.8

The question asks how many hours each person worked, and how much they earned, or basically they're asking for the right two columns to be filled in. (Total hours = how many hours each person worked, and Total pay = how much they earned)

If we look at the table, we can see we're given information for each person, Sue, Bob, and Chris. We're given their rate per hour, and the numbers of hour they worked for each day.

The two things we are looking to calculate can correspond with a part of information we're given:

Find the total hours worked for each person:

We have now calculated the total hours for each person. You can therefore fill in the column of total hours, starting from the top, with 37.25 hours, then 32 hours, and finally 30.25 hours.

As I stated earlier, the only thing needed to do to find the total pay is to multiply the total hours my the rate per hour.

Let x be the speed of the motorboat and y be the speed of the current.

Then, for downstream, the speed is x + y.

Now, speed = distance/time.

Distance = 80 miles.

Time for downstream = 4 hours.

So, x + y = 80/4 = 20     (1)

Against the current, that is for upstream, the speed is x - y.

Time for upstream = 5 hours.

x - y = 80/5 = 16     (2)

Adding (1) and (2), we get,

2x = 36

x = 18

Hence, rate of the motorboat in calm water = 18 miles/hour.

To cover costs and achieve a $90 profit, each collar should be sold for $175 divided by the number made.

To determine the selling price for each dog collar, we need to consider both the cost of materials and the desired profit.

1. **Calculate total cost**:

  - Cost of materials: $85

  - Desired profit: $90

  Total cost = Cost of materials + Desired profit

             = $85 + $90

             = $175

2. **Determine number of collars**:

  Since you anticipate selling all the collars, the total profit should cover the cost of materials and the desired profit.

3. **Calculate selling price per collar**:

  Divide the total cost by the number of collars to determine the selling price for each collar.

[tex]\[ \text{Selling price per collar} = \frac{\text{Total cost}}{\text{Number of collars}} \][/tex]

Substitute the values:

[tex]\[ \text{Selling price per collar} = \frac{\$175}{\text{Number of collars}} \][/tex]

Without knowing the exact number of collars, we can't determine the exact selling price per collar. However, if you know the number of collars you're making, you can use this formula to find the selling price for each collar.
