The charity gala costs a flat fee of $4, plus an additional $11 per attendee. Is the total cost directly proportional to the number of attendees?
No, the total cost is not directly proportional to the number of attendees because there is a flat fee of $4 that does not depend on the number of attendees. If the total cost were directly proportional to the number of attendees, then the cost per attendee would be constant regardless of the number of attendees, but in this case, the cost per attendee decreases as the number of attendees increases due to the fixed flat fee.
Missy’s sister,Jolly the Carpenter has 10 orders that she needs to finish in 24 hours. She has to make a table which will take her 1.5 hours,a rocking horse which will take 45 mins,a rocking chair which will take 50 mins,2 chairs which will take 54 minutes each,a duck call which will take 30 mins,a wooden car toy which will take 45 mins ,a huge boat which will take 5 hours,and a tiny toy table which will take 15 minutes. How many minutes will she have left over ?
Let's convert all the times to minutes for easier calculations.
1.5 hours = 90 minutes
45 minutes = 45 minutes
50 minutes = 50 minutes
54 minutes = 54 minutes
30 minutes = 30 minutes
45 minutes = 45 minutes
5 hours = 5 x 60 = 300 minutes
15 minutes = 15 minutes
To find the total time Jolly will spend on all the orders, we add up all the times:
90 + 45 + 50 + 54 + 54 + 30 + 45 + 300 + 15 = 683 minutes
Jolly has 24 hours = 24 x 60 = 1440 minutes to complete all the orders. To find out how many minutes she will have left over, we subtract the total time she will spend on the orders from the total time available:
1440 - 683 = 757 minutes
Therefore, Jolly will have 757 minutes left over after completing all 10 orders.

Answer:
x = 7
Angle A = 74
Angle B = 16
Proofs attached to answer
Step-by-step explanation:
Proofs attached to answer
Answer:
<A = 74
Step-by-step explanation:
We know that being complementary angles refer to..Sum of two angles = 90°.
So,
<A + <B = 90
i.e. (7x + 25) + (x+9) = 90
or, 8x + 34 = 90
or, 8x = 90-34
or, x = 56/8
or, x = 7
Again,
<A = 7x + 25
or, <A = 7*7 + 25
or, <A = 74

Calculate the probability of the event.
Answer:
well, the other colors on the wheel are less because people prefered green
Step-by-step explanation:
Step-by-step explanation:
So its hard to calculate actual probability without any numbers. But seeing that there are a total of 6 colors on the wheel, and that green is the largest (by a lot since its almost half the wheel) the probability of landing green is very high.
And that's all you can say really...black will be lowest, and yellow seems to be the next highest. In comparison to green though, probability of the other colors will be low.

D) Multiply one dimension of the prism by two and keep the other dimensions the same.
Step-by-step explanation:
When multiplying a volume of a rectangular prism regularly it would be B×h or l×w×h would be 10×2×5 = [tex]100cm^{3}[/tex].
However if doubled, or multiplied by 2 our new result would be [tex]200cm^{3}[/tex]. The way to find this is by multiplying only one dimension, or side, as the rest will remain the same.
There are 3 possible equations you could do with the given information.
(10×2)×2×5, 10×(2×2)×5, or 10×2×(5×2).
All of these, individually multiply up to 200 which is also double the amount of the regular volume.
I hope this was helpful!

Sure, here are the questions and solutions for module 3 page 330 in Carnegie textbook:
If the cost of goods sold is 65% of sales and sales are $720,000, what is the cost of goods sold?
To find the cost of goods sold, we need to multiply the sales by the percentage of the cost of goods sold, expressed as a decimal:
Cost of goods sold = 0.65 × $720,000
Cost of goods sold = $468,000
Therefore, the cost of goods sold is $468,000.
At a cost of $110 each, how many calculators can be purchased with a budget of $8,800?
To find the number of calculators that can be purchased, we need to divide the budget by the cost per calculator:
Number of calculators = $8,800 ÷ $110
Number of calculators = 80
Therefore, 80 calculators can be purchased with a budget of $8,800.
a is the cost of adult tickets.
s is the cost of students tickets.
The cost of each type of ticket is $10.
The solution of an equation differ from the solution of a linear system of equations because because it only satisfies a single equation.
How to determine the number of each type of tickets sold?In order to write a system of linear equations to describe this situation, we would assign variables to the cost of adult tickets sold and cost of student tickets sold, and then translate the word problem into an algebraic equation as follows:
Let the variable a represent the cost of adult tickets sold.Let the variable s represent the cost of students tickets sold.The total amount of money that Ashley charged the first person is represented by this linear equation:
2a + 2s = 40
For the second person, we have:
a + 3s = 40
By solving the system of linear equations simultaneously, we have:
2(40 - 3s) + 2s = 40
80 - 6s + 2s = 40
4s = 40
s = $10.
For the value of adult ticket (a), we have:
a = 40 - 3s = 40 - 3(10) = $10.
For the third person, we have:
Cost = 3a + 5s
Cost = 3(10) + 5(10) = $80.

The scale used for a model of an Orca whale is 1 in: 4
ft. If the model of the Orca is 5 inches long, how long is
the actual whale?
Answer: this is unrealistic but the way the question is written it makes me believe that the orca is 20 ft but that’s defiantly wrong so it’s either a really small whale or you add a zero at the end and are you sure you didn’t leave out any details because the question is written in a weird way

QUESTION 1
The value of the x for the given square such that its perimeter is 28 meters will be 3.7 meters.
What is a square?
A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.
Area of square = Side²
The perimeter of the square = 4 × side
As per the given square perimeter.
4(x + 3.3) = 28
x + 3.3 = 7
x = 3.7 meters.
Hence"The value of the x for the given square such that its perimeter is 28 meters will be 3.7 meters".

Step-by-step explanation:
in order for Michael to know how many more points he needs to equal with Janet he need to add how many points she has (200 + 400) then subject how much he has (250) and get p
(200 + 400) - 250 = p
you need to do 200 + 400 first, hence the parentheses.
There are five different colored cards in a hat (red, blue, green, yellow, and black). A card is randomly drawn and not replaced. Then a second card is drawn. What is the probability that the first card will be red and the second card will be blue?
4%
25%
5%
20%
Answer:
The probability will be 5%
Step-by-step explanation:
The probability that you pulled red first was 1/5, or 20%
And the probability you pulled blue second was 1/4, or 25%.
Now we have to multiply the fractions.
1/5x1/4=1/20. 1/20 is 5%. There is a 5% probability you pulled red then blue.
