Need help with B. and C.

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.

A flying disc is assumed to be in the shape of a circle. Since we know it is in the shape of a circle, we can use the formula for circumference of a circle.

The formula for circumference of a circle is d * pi, where d represents the diameter of the circle and pi is the representation of 3.14.

You can find the circumference of a circle by multiplying the diameter by pi, and since the question gives us the diameter of the flying disc we can substitute in 9 inches for the diameter to solve for the circumference.

diameter * pi

(9 inches) * ([tex]\pi[/tex]) = 28.2743...

The question wants the final answer to be rounded to the nearest tenth, so rounding 28.2743... to the nearest tenth would make it into 28.27.

The answer to this problem is the circumference of the disc is 28.27 inches.

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).

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

Brenda is able to complete 2/3 of a friendship bracelet in one hour, based on the rate given in the question.

This question deals with rate and time, key concepts in Mathematics. Brenda can finish 1/3 of a bracelet in 1/2 hour, which means she completes 2/3 of a bracelet in one hour. Let me explain why.

We start with the given rate: 1/3 bracelets per 1/2 hour. To find out how many bracelets Brenda can complete in 1 hour, we simply multiply this rate by 2 (as 1 hour is equivalent to two 1/2 hours). Therefore, Brenda can complete (1/3 bracelet/1/2 hour) x 2 = 2/3 of a bracelet in one hour.

The attempt to solve the provided system of equations by elimination encountered a misunderstanding in the manipulation of the equations. A straightforward correction highlighted the importance of accurately aligning coefficients before attempting to eliminate a variable, underscoring the necessity of precise calculations in solving such problems.

To solve the given system of equations by elimination, we start with the system:

Our goal is to eliminate one of the variables, either x or y. To do this efficiently, we aim to make the coefficients of either x or y the same or exact opposites. In this case, we can easily adjust the second equation to align the coefficients of y by multiplying the entire equation by a suitable number.

Multiply the first equation by 1 (effectively keeping it the same) and the second equation by 7/4 to align the y coefficients:

However, there seems to be a misunderstanding in the calculation or transcription of the equations provided. Instead, let's correct the approach based on the equations listed in the inquiry.

Looking at the original system provided:

We see an opportunity to simplify the first equation by dividing everything by -7:

Now, to proceed with elimination effectively, aligning coefficients or a straightforward substitution should be re-evaluated, given the error in initial steps noted. Let's correct it:

Notice the instructional error in application; hence, a direct solution via the provided method is not feasible without the correct system alignment or revised equations. When solving similar problems, getting coefficients to align through multiplication or division is key before adding or subtracting equations to eliminate a variable.

Elimination becomes difficult with inaccurate steps, so it's crucial to double-check each phase of your work.

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.

It is linear because both variables have an exponent of 1. (FYI: one of the exponents can be 0 and still be a linear equation).

2x + y = 8

-2x     -2x

      y = -2x + 8   ⇒ slope (m) = -2 and y-intercept (b) = 8

plot the y-intercept (0, 8). then plot the next point by counting the rise over run from the y-intercept. count 2 units down and 1 unit to the right = (1, 6).

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

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.

The commutative property is illustrated by option D, where adding sprite and orange juice to a punch mixture shows that the order in which the ingredients are mixed does not affect the final product.

The commutative property primarily relates to mathematical operations like addition and multiplication, where changing the order of the numbers does not change the result. For example, in addition, 4 + 5 is the same as 5 + 4. Applying this concept to the options provided, the pair that is an example of the commutative property is adding sprite and orange juice to a punch mixture (Option D). Whether you add sprite to the orange juice or orange juice to the sprite, the resulting punch mixture remains the same.
