Answer: AFC won 18 times, NFC won 20 times
============================
N = number of times an NFC team won the superbowl
A = number of times an AFC team won the superbowl
The two unknown numbers (N and A) must add to 38 as there are no other options (either there is an NFC or AFC champion) so N+A = 38
The other equation is N = A+2 because "the NCF won two more games than the AFC"
We can replace the "N" in N+A = 38 with A+2 because N = A+2, meaning that N and A+2 are the same
So,
N+A = 38
A+2+A = 38 ... replace N with A+2; solve for A
2A+2 = 38
2A+2-2 = 38-2
2A = 36
2A/2 = 36/2
A = 18
The AFC won 18 times. Use this value of A to find N
N = A+2
N = 18+2
N = 20
The NFC won 20 times.
As a check, adding up the two counts should get us 38
N+A = 38
20+18 = 38
38 = 38

Ginger's cat gave birth to a kitten that weighed ounces when it was born. On the day Ginger sold the kitten to its new owner, it weighed ounces. How many ounces did the kitten gain before it went home with its new owner?
Answer:
C. 2 1/8 ounces
Step-by-step explanation:
The kitten gained 2 1/8 ounces, and you can prove it through the following reasoning.
Kitten at birth was 3 3/8 ounces
Gained Weight (WG) was (unknown)
The kitten was 5 1/2 after being sold.
5 1/2 - 3 3/8 = GW (please note that 1/2 is also 4/8, therefore the equation can be represented by 5 4/8 - 3 3/8 = GW
2 1/8 = GW
Answer: The kitten gained 2 1/8 ounces
Step-by-step explanation:
We have to find the difference between the weights of kitten.
5 1/2 - 3 3/8 = weight gained
We solve the compound fraction like this.
5 1/2
2*5+1 = 11
This goes to 11/2
While
3 3/8
8*3+3 = 27
This goes to 27/8
So we subtract 11/2 - 27/8
44 - 27/8
17 / 8
This comes to 2 1/8 ounces.

Find the length of x.
Answer:
x=7
Step-by-step explanation:
The two triangles are similar .
We can use the ratio's of the side to figure out x
2 3.5
-------- = --------------
4 x
Using cross products
2x = 4*3.5
2x=14
Divide each side by 2.
2x/2 = 14/2
x=7
the length of x = 7.
To solve for x using the given ratios of the sides of the two similar triangles, we can follow these steps:
Set up the proportion using the given ratios:
[tex]\[ \frac{2}{4} = \frac{3.5}{x} \][/tex]
Cross multiply:
[tex]\[ 2x = 4 \times 3.5 \][/tex]
Perform the multiplication on the right side:
2x = 14
To solve for x, divide both sides of the equation by 2:
[tex]\[ \frac{2x}{2} = \frac{14}{2} \][/tex]
Simplify both sides:
[tex]\[ x = \frac{14}{2} \][/tex]
Calculate the value:
x = 7
So, x = 7.

A car dealer has 7 new sedans she wants to display but room for only 5 on the showroom floor.
How many ways can she display the 7 cars on the showroom floor?
a. 35
b. 21
c. 5040
d. 2520
Answer:
B) 21
Step-by-step explanation:
There are 7 cars total and 5 slots to fill for the showroom selections. Put another way, there are 7-5 = 2 cars that don't make it to the showroom floor. Since this value (2) is smaller than the previous number of slots (5), it makes it easier to ask the question "how many ways are there to pick 2 cars that don't make it to the show room floor?" instead of "how many ways are there to pick 5 cars that make it to the showroom floor?". We'll get the same answer either way.
So we have 7 total to pick from for slot 1, and then 6 left over for slot 2. Making 7*6 = 42 permutations. Order does not matter, meaning that picking a red car and then a blue car is the same as picking a blue and then red. The count 42 has double counted, so we divide by 2 to sort this out
42/2 = 21 represents the number of combinations. We can see this if we use the nCr combination formula with n = 7 and r = 2
nCr = (n!)/(r!*(n-r)!)
7C2 = (7!)/(2!*(7-2)!)
7C2 = (7!)/(2!*5!)
7C2 = (7*6*5!)/(2*5!)
7C2 = (7*6)/2
7C2 = 42/2
7C2 = 21
a similar computation happens if you use n = 7 and r = 5.
in a certain city , the hourly wage of workers on temporary employment crontracts is normally distributed. The mean is $15 and the standar deviation is $3. What percentage of temporary workers earn less than $12 per hour?
A) 6%
B) 16%
C) 26%
D) 36%
Answer:
16%
Step-by-step explanation:
The mean is $15 and the standar deviation is $3.
mean = 15 and SD = 3
We need to find percentage less than 12 per hour
P(x<12)= P(x=12)
to find P(x=12) we find z-score
[tex]z= \frac{x-mean}{SD} =\frac{12-15}{3} =-1[/tex]
Now use z-score table . z-score = 0.1587
P(x=12)=0.1587
To get percentage we multiply by 100
0.1587 * 100 = 15.87 = 16%

After an outbreak of a mysterious disease the average wait time at a hospital increased by 70%. Before the outbreak, the average wait time at the hospital with M minutes. Which of the following expressions could represent the average time at the hospital after the outbreak? Choose two answers:
Answer:
[tex]\frac{170}{100}m[/tex]
[tex]1.7m[/tex]
Step-by-step explanation:
Here,
Before the outbreak, the average wait time at the hospital was m minutes,
Also, after outbreak it is increased by 70 %,
So, the average wait time at the hospital after the outbreak = The average wait time before outbreak + 70 % of the average wait time before outbreak
= m + 70 % of m
[tex]=m+\frac{70m}{100}[/tex]
[tex]=\frac{100m+70m}{100}[/tex]

The expression 2 sqrt(20) - 3 sqrt(7) - 2 sqrt(5) + 4 sqrt(63) simplifies to 2 sqrt(5) + 9 sqrt(7) after breaking down and combining like radicals.
We start by simplifying each radical. Notice that sqrt(20) can be written as sqrt(4*5), which simplifies to 2sqrt(5). Similarly, sqrt(63) can be written as sqrt(9*7), which simplifies to 3sqrt(7). Therefore, our expression becomes:
2(2sqrt(5)) - 3sqrt(7) - 2sqrt(5) + 4(3sqrt(7)) = 4sqrt(5) - 2sqrt(5) - 3sqrt(7) + 12sqrt(7) = 2sqrt(5) + 9sqrt(7). This gives us the simplified form of the original expression.

The same number of guests are seated at each of 12 large tables. There are 2 guests seated at one small table. Write an equation to represent the total number of guests T and the number of people x at each large table. If there are 122 guests, how many are seated at each large table?
An equation to represent this would be 12x+2=T.
x=10 people per large table.
If T=122 then we just have to isolate x on one side of the equation. The first step is to replace T with 120 and then subtract 2 on both sides (to cancel the +2) to get 12x=120. Cancel the 12 by dividing both sides by 12 to get x=10. The number of people seated at each large table would be 10. Hopefully I explained this correctly and helped you understand.
Final answer:
To determine the number of guests seated at each large table, we use the equation T = 12x + 2, where T is the total number of guests and x is the number of guests at each large table. Solving for x given T = 122 guests, we find that
x = 10, meaning there are 10 guests at each large table.
Explanation:
The student asks for help with writing an equation to represent the total number of guests T and the number of people x at each large table, given that there are 12 large tables and one small table with 2 guests. The student also seeks to find out how many people are seated at each large table if there is a total of 122 guests.
The equation to represent the scenario is T = 12x + 2, where T is the total number of guests, and x is the number of guests at each large table. Since we know there are 122 guests in total:
Substitute T with 122 in the equation: 122 = 12x + 2.
Subtract 2 from both sides to isolate the terms with x: 120 = 12x.
Divide both sides by 12 to solve for x: x = 120 / 12.
Calculate the result: x = 10.
Therefore, there are 10 guests seated at each large table.

The prices per pound of different types of nuts are shown. write an expression that can be used to find the total cost of 2 pounds of peanuts, 3 pounds of cashews, and 1 pound of almonds, all for 20 % off.
Peanuts = $3.95 per pound
Cashews = $4.25 per pound
Almonds = $5.99 per pound
Please help! Thank you
Answer:
expression for total cost is given by
[tex]0.80(3.95x+4.25y+5.99z)[/tex]
Step-by-step explanation:
Here we need to find the expression for the total cost
Let us find the cost for x pounds of peanut , y pounds of cashews and z pounds of almonds
cost of 1 pound of peanut = $3.95
cost of x pounds of peanut = $3.95x
cost of 1 pound of cashews = $4.25
cost of y pounds of cashews = $4.25y
cost of 1 pounds of almonds = $5.99
cost of z pounds of almonds = $5.99z
total cost = [tex]3.95x+4.25y+5.99z[/tex]
cost after 20% off = total cost - 20% of total cost
= 80% of total cost
cost after 20% off =80%[tex](3.95x+4.25y+5.99z)[/tex]
cost after 20% off =[tex]0.80(3.95x+4.25y+5.99z)[/tex]
now we can plug x= 2 , y= 3 and z=1
so we have
cost after 20% off =[tex]0.80(3.95(2)+4.25(3)+5.99(1))[/tex] =$ 21.31
The expression is ((2 x $3.95) + (3 x $4.25) + (1 x $5.99)) x (1 - 0.20) which equals to $21.31.
To find the total cost of 2 pounds of peanuts, 3 pounds of cashews, and 1 pound of almonds with a 20% discount, we need to first calculate the original total cost of the nuts without the discount.
We do this by multiplying each type of nut's price per pound by the number of pounds purchased and summing these amounts up.
The cost for the peanuts is 2 pounds x $3.95 per pound = $7.90.
For the cashews, it is 3 pounds x $4.25 per pound = $12.75.
For the almonds, it is 1 pound x $5.99 per pound = $5.99.
The sum of these costs will give us the total original cost.
The total original cost is therefore $7.90 (peanuts) + $12.75 (cashews) + $5.99 (almonds) = $26.64.
Next, we apply the 20% discount by multiplying the total original cost by 20% (or 0.20) to find the discount amount, and then subtract this discount amount from the total original cost to find the discounted total cost:
Discount amount = $26.64 imes 0.20 = $5.33. Discounted total cost = $26.64 - $5.33 = $21.31.
Therefore, the expression that can be used to find the total cost is: ((2 x $3.95) + (3 x $4.25) + (1 x $5.99)) x (1 - 0.20)

how do I graph x is greater than or equal to minus 3
x > -3
The x-values are always the same while the y-values change, so x=-3 is a vertical line.
Draw a solid line, NOT dotted, for greater than or equal to.
All values of x greater or equal to -3 means everything to the right of your line. Shade that in.
To graph the inequality x is greater than or equal to -3, start by marking -3 on the number line with a filled dot because it includes 'equal to'. Then draw a line extending to the right from the -3 mark to represent values greater than -3.
Explanation:To graph the inequality x is greater than or equal to -3, start by drawing a number line representing x values. Mark -3 on this line. Because the inequality includes 'equal to', plot a filled dot at -3 on your line, indicating that -3 is included in the solution.
Next, since the inequality states x is greater than -3, draw a line extending to the right from the -3 mark, representing all numbers greater than -3.
This graph shows all the x values that satisfy the inequality x is greater than or equal to -3. Any x value on this line or to the right of the -3 mark will make the inequality true.

To solve the system of linear equations 3x-2y=4 and 9x-6y=12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3x-2y=4 and 9x-6y=12 with his graphing calculator, but he could only see one line. Why is this?
A.because the system of equations actually has only one solution
B.because the system of equations actually has no solution
C.because the graphs of the two equations overlap each other
D.because the graph of one of the equations does not exist
The coefficients and constants of the equations are proportional to each other because the graphs of the two equations overlap each other.
The correct option is C.
When Henry multiplied the first equation by -3 and added the two equations together, resulting in the equation 0 = 0, it indicated that the two original equations were dependent and represented the same line. This means that the system of equations has infinitely many solutions. Each point on the line represented by the equations satisfies both equations simultaneously.
When Henry graphed the equations on his graphing calculator and saw only one line, it further confirmed that the two equations are identical or overlapping. The lack of a visible second line indicates that the graphs coincide with each other, overlapping perfectly. This occurs because the coefficients and constants of the equations are proportional to each other, resulting in the same line when graphed.
Hence, option C is the correct choice, as the overlapping of the graphs confirms that the system of equations has infinitely many solutions.

2 * 1.5 = 3 total inches.
4 hours - 2 hours = 2 hours left
2 hours x 1 inch per hour = 2 total inches.
Total snow fall = 6 + 3 + 2 = 11 inches.
11 inches is less than the height of the three cans.
2. 11 inches / 12 inches per foot = 0.9167 feet.
Volume of snow = 2 x 8 x 0.9167 14.67 cubic feet of snow needs to be removed.
What is the selling cost of a jacket that the store buys for $60 if the markup is 12%?
Answer:
$67.20
Step-by-step explanation:
We need to find out how much 1% costs so we can multiply that cost by 12 because it goes up 12%.
60/100=0.6
0.6*12=7.2
Now that we have the markup amount we add it to the actual price of $60 so
60+7.2=$60.20
