Answer: -3
Step-by-step explanation: using the mathematical process
4-(4/4)-6=
4-1-6= -3
Is this the whole question? If so, this how I found my answer(I do not know if this is the answer 100% and I won't and can't take credit for the answer being incorrect. It is your choice to go with my answer, thank you.):
A restaurant can seat 100 people. Okay, the capacity is 100. Got it. It has booths that seat 4 people. Okay! So I am going to represent B"Booths" as "B". A variable. B = 4. Okay, let's continue. And, it has tables that seat 6 people. I will represent "Tables" as T. So, T = 6!
Alllrighty then, let's get to the nit and grit..
B = 4 T = 6
In the last sentence, it says, 5 of the booths are full, what expression matches the situation? Well, it's ONLY asking for the expression, so that's all we'll give.
We don't need the "table" variable because it's asking about the booths so, bye bye tables. B = 4, and 5 of them are full. We would have to do B(5) or B * 5. B equals 4 so 4 * 5 which equals 20. The expressions we could use are:
B(5) = 20
or
4 * 5 = 20
or
20 = 4 * 5 = B(5)
I hope this answer helps you out! Bye! :)
The mean and range for class A are 84.4 and 20 while the mean and range for class B are 83.6 and 8. Class B is more consistant then class A.
<h3>How to calculate the mean?</h3>
We can see from the data that the consistency of class B is more becuase the repeatation of the same score is more in class B then class A and the range of class B is also less then the class A.
It should be noted that mean simply means average. It's the addition of the numbers divided by the total numbers.
In this case, the computation will be:
Class A: Mean = 422/5= 84.4.
Range: 94-74 = 20
Class B: Mean = 418/5 = 83.6.
Range= 88-80 = 8

Answer:
Step-by-step explanation:
The area of a triangle can be given as . Notice that a base of the triangle is given as 4 units, and the height is marked as 5 units. We know that the segment marked as 5 units is the height of the triangle because it forms a with the segment marked as 4 units and meets a vertex of the triangle.
Therefore, the area of the triangle is:
.
Equation of cost per month: 39.95+0.35((x-500)=>0)=cost. (x=minutes of usage)
Explanation: The cell phone plan, at the start of a month costs $39.95, which is graph terms is the Y intercept. Thus the "39.95+" at the start of the equation. Since the first 500 minutes is free, then the cost of the plan must start after these 500 minutes, which is why there is a -500 for the amount of minutes used, but because the amount of minutes can be less than 500, which will result to a negative number (which can not happen, because these minutes are free), we must add a "greater than or equal to 0" sign at the end of t-500, so that the result must be 0 minutes or more. Since the cost of every minute after the first 500 minute costs $0.35, we must add that to the amount of minutes of usage that have passed, thus the 0.35x. All the results to 39.95+0.35((x-500)=>0)=cost in dollars
as for the bill of $67.70 questions, we simply have to plug this into the equation, making:
39.95+0.35((x-500)=>0)=$69.70
-39.95 -39.95
0.35((x-500)=>)=$29.75
/0.35 /0.35
x-500=85
+500 +500
x=585
So the answer is that it takes 585 minutes of usage to receive a bill of $69.70.
