Should be 30 meatballs. This is because there are 25 adults and 5 kids. 25+5 = 30. That is the least amount you need. However, most people try to provide at least 2 servings per person. So that would be 60 meatballs. That way each person has two meatballs. Hope this helps, if so please give brainliest:-)
Answer:
= $44.19
Step-by-step explanation:
APR = 19%
Billing cycle = 30 days
Balance = $2830
Let's first find the daily rate,
Daily rate = 
The daily rate = 0.000521
To calculate the amount Shirley was charged interest for the billing cycle, we use:
Daily rate * billing cycle * balance
Where,
Daily rate
= 
Billing cycle = 30 days
Balance = $2830
Therefore, expression to be used =
The slope (m) of the line graphed is -4/2, because the line goes down 4 (-4) and over 2 (+2), which is change in y over change in x
m = -4/2 = -2
the y-intercept (b) of the line = -1, because the line crosses the vertical line at x=0 at y=-1
now for the equation:
y = mx + b
y = -2x + -1 = -2x - 1
f(x) = -2x-1
the last answer is correct
We conclude that the profit if the company produces 10 units is 1,040 dollars.

How to find the profit?</h3>
The profit is defined as the difference between the revenue and the costs.
In this case, we know that the revenue and costs are defined by:
R(x) = 200x - 5x^2
C(x) = 360 + 6x
Then the profit equation is:
P(x) = R(x) - C(x).
P(x) = 200x - 5x^2 - (360 + 6x)
P(x) = -5x^2 + 194x - 360
Now we want to find the profit when x = 10, then we will get:
p(10) = -5*10^2 + 194*10 - 360 = 1,040
We conclude that the profit if the company produces 10 units is 1,040 dollars.

Answer:
B. The vectors v and w are orthogonal because their dot product is <u> 0 </u>
Step-by-step explanation:
Given that :
v= - i - j
w= - i + j
Therefore;
vw = ( - i - j ) ( - i + j )
Taking each set of integer of the vector into consideration:
vw = ( -1 × - 1) ( -1 × 1)
vw = 1 - 1
vw = 0
Hence, we can conclude that :
The vectors v and w are orthogonal because their dot product is <u> 0 </u>
