You are having a dinner catered. You pay a rental fee of $150 for the dining hall, and you pay the caterer $10 for each person who attends the dinner. How much should you charge per ticket if you expect 50 people to attend? (Round your answer to the nearest cent.)
Answer:
$13
Step-by-step explanation:
For 50 people it will cost you 150 + 50(10) or 500
150 +500 = 650 Divide that among 50 people and you get a cost of $13 a person.

XZ is the perpendicular bisector of segment WY. Solve for k. Enter a NUMBER only.
Given that XZ is the perpendicular bisector of segment WY, the numerical value of k is 4.
What is the numerical value of K?A bisector divides an angle or segment into two equal halves.
Given the data in the question;
XZ is the perpendicular bisector of segment WYSegment WX = 6k + 8Segment XY = 11k - 12Value of k = ?Since XZ is a perpendicular bisector of segment WY,
Segment WX is equal to Segment XY
Segment WX = Segment XY
Plug in the given values and solve for k.
6k + 8 = 11k - 12
Collect like terms
6k - 11k = -12 - 8
-5k = -20
Divide both sides by the coefficient of k
-5k/-5 = -20/-5
k = 4
Given that XZ is the perpendicular bisector of segment WY, the numerical value of k is 4.

A group of people were asked if they had run a red light in the last year. The number of people that
responded yes is 397 and no is 159. Find the probability that if a person is chosen at random, he/she has
run a red light in the last year. Round to two decimal places.
Question Help:
If a person is chosen at random, there is a 71% probability that he or she has run a red light in the last year.
What do we mean by probability?Probability is a branch of mathematics that deals with numerical descriptions of how likely an event is to occur or how likely a proposition is to be true. The probability of an event is a number between 0 and 1, where 0 indicates the event's impossibility and 1 indicates certainty.So, to find the probability:
P = number of favorable terms/number of total termsFavorable terms = 397Total number of terms = 397 + 159 = 556Apply values in the formula:
P = 397/556P = 0.714028On rounding off, P = 71%.Therefore, if a person is chosen at random, there is a 71% probability that he or she has run a red light in the last year.

-
Number 50 in the Jack's equation represents the rate of change in the oven's temperature over time (per minute) or with respect to time by using the slope form concept.
As per the question statement, Jack is preheating his oven before using it to bake. He wants to predict the final temperature after [tex]x[/tex] minutes.
He wrote the equation [tex]y =50x+78[/tex] , where [tex]y[/tex] represents the final temperature in [tex]fahrenheit[/tex]. We are supposed to tell the significance of number 50 in the given equation.
As we know that the equation which is in the form of [tex]y=mx+c[/tex], or the slop form equation, m is called the slope or the rate of change of value of [tex]y[/tex] with respect to value of [tex]x[/tex].
And the given equation [tex]y =50x+78[/tex] is also of the form of [tex]y=mx+c[/tex] hence we conclude that 50 is the slope or the rate of change of value of [tex]y[/tex] with respect to value of [tex]x[/tex].
As y is the temperature in Fahrenheit therefore x is the time hence "50 Degrees Fahrenheit change of temperature per unit minute" is the significance of 50.

they divide the money so that each person gets a fair share?
Answer:
Steve: $138.00
Jenna: $72.00
Step-by-step explanation:
Steve:
[tex]\frac{23}{35}[/tex] x 210 = 138
Jenna:
[tex]\frac{12}{35}[/tex] x 210 = 72
I'm not really sure what this means, but i'll do what i think is right!
Answer:
Steve: $138
Jenna: $72
Step-by-step explanation:
If you're doing it so they each get what they sold, you would have to first add the total number of chocolate bars, giving you 35. To see how much each bar costs, you just have to divide $210 ÷ 35, giving you $6 per chocolate bar.
To give each what they gained, you multiply $6 by whichever amount you chose, 23 or 12, which will give you that person's amount. Steve will get $138 and Jenna will get $72.

!Rewrite 2,290,000 in scientific notation.
2.29 x 10−6
2.29 x 10−4
2.29 x 104
2.29 x 106
2,290,000 in scientific notation is 2.29 x 10⁶.
What is scientific notation?Scientific notation is a way of expressing numbers that are too large or too small (usually would result in a long string of digits) to be conveniently written in decimal form. It may be referred to as scientific form or standard index form, or standard form in the United Kingdom. This base ten notation is commonly used by scientists, mathematicians, and engineers, in part because it can simplify certain arithmetic operations.
Converting a number in these cases means to either convert the number into scientific notation form, convert it back into decimal form or to change the exponent part of the equation.
Now the given number is,
2,290,000
To convert 2,290,000 into scientific notation, 2,290,000 must be converted into into decimal and multiples of 10.
So, factorizing 2,290,000 we get,
2,290,000 = 229 x 10,000
Now converting 10,000 into multiples of 10
Since, 10,000 = 10 x 10 x 10 x 10
So, 2,290,000 can be written as,
2,290,000 = 229 x 10 x 10 x 10 x 10
Multiplying and divide 229 by 100 we get,
2,290,000 = (229 x 100 x 10 x 10 x 10 x 10) / 100
Rearranging we get,
2,290,000 = (229 x 100) / 100 x (10 x 10 x 10 x 10)
Since, (229 x 100) / 100 = 2.29 x 100
2,290,000 = (2.29 x 100) x (10 x 10 x 10 x 10)
And 100 = 10 x 10
Therefore we get,
2,290,000 = 2.29 x 10 x 10 x 10 x 10 x 10 x 10
Since 10 x 10 x 10 x 10 x 10 x 10 = 10⁶
Therefore we get,
⇒ 2,290,000 = 2.29 x 10⁶
this is the required scientific notation of 2,290,000 .
Thus, 2,290,000 in scientific notation is 2.29 x 10⁶.

Both values are approximate
=======================================================
Work Shown:
21 min = 21/60 = 0.35 hrs which is exact
distance = rate*time
rate = distance/time
rate = (1 mile)/(0.35 hrs)
rate = (1/0.35) mph

If 6 -x = 12, what is x - 6?
Answer: x - 6 = -12
Step-by-step explanation: first, we'll solve for x in 6 - x = 12. We'll isolate the variable by subtracting 6 from both sides, which gives us -x = 6. Now we'll divide both sides by -1 to get x and we will get -6 = x. So for the expression, we'll sub in the value we got for x from the equation, -6. -6 - 6 = -12.

A.150 feet
B.178 feet
C. 191 feet
D.212 feet
A square field has an area of 22,500 square feet, then the diagonal distance across the field in nearest foot is equal to 212 foot (approximately).
As given in the question,
Area of the square field = 22,500square feet
Let 'a' be the side and 'd' be the diagonal length of the square
a² =22,500
⇒a =150 foot
Using Pythagoras theorem
d² =a² +a²
⇒d² = 2(150)²
⇒d² =45000
⇒d =212.13
≈ 212 nearest foot (approximately)
Therefore, the diagonal distance across the field in nearest foot is 212 foot (approximately) with area of 22,500 square feet as given.

The value of x will be 2. So, Option B is correct for the equation [tex]3^{2x} = 9^{3x - 4}[/tex]
In the given question, the equation is [tex]3^{2x} = 9^{3x + 4}[/tex], we have to find out the value of x. First, we need to re-arrange the equation in order to apply the property of exponents. So,
=> [tex]3^{2x} = 9^{3x -4}[/tex] => [tex]3^{2x} = 3^{2(3x - 4)}[/tex]
We know according to the property of exponents if [tex]x^{m} = x^{n}[/tex], then m = n.
Similarly, in this equation the base of both RHS and LHS are the same, We get
=> 2x = 2(3x - 4)
=> 2x = 6x - 8 => 4x = 8
=> x = 2
We get value of x = 2.
Hence the value of x for this equation will be 2 and option B is correct.

The banker should invest $ 30,000 at 6 % interest rate to earn an interest of 3800 per year from both the investments.
Principal 1 = $ 50,000
Rate 1 = 4 %
Let principal 2 be x
Rate = 6 %
Time = 1 year
Interest = 3800
Using simple interest, we get that:
SI = p × r × t
3800 = ( 50,000 × 0.04 × 1) + ( x × 0.06 × 1)
3800 = 2000 + 0.06 x
0.06 x = 3800 - 2000
0.06 x = 1800
6 x = 180000
x = 180000 / 6
