Answer:
Buffalo mild wings offers the lowest price per wing ($0.83).
Step-by-step explanation:
Let us find unit price per buffalo wing of each restaurant.
[tex]\text{Unit rate for buffalo bills}=\frac{\$7}{8\text{ wings}}[/tex]
[tex]\text{Unit rate for buffalo bills}=\frac{\$0.875}{\text{ wing}}[/tex]
Upon rounding our answer to nearest cent we will get,
[tex]\text{Unit rate for buffalo bills}=\frac{\$0.88}{\text{ wing}}[/tex]
Therefore, buffalo bills offers each wing for $0.88.
[tex]\text{Unit rate for buffalo mild wings}=\frac{\$10}{12\text{ wings}}[/tex]
[tex]\text{Unit rate for buffalo mild wings}=\frac{\$0.83333}{\text{ wing}}[/tex]
Upon rounding our answer to nearest cent we will get,
[tex]\text{Unit rate for buffalo mild wings}=\frac{\$0.83}{\text{ wing}}[/tex]
Therefore, buffalo mild wings offers each wing for $0.83.
[tex]\text{Unit rate for wingers}=\frac{\$17}{20\text{ wings}}[/tex]
[tex]\text{Unit rate for wingers}=\frac{\$0.85}{\text{ wing}}[/tex]
Therefore, wingers offers each wing for $0.85.
We can see that buffalo mild wings offers the lowest price per wing that is $0.83 per wing.

Omar has a new credit card. He earns 300 reward points for every 100 dollars he spends. If Omar earned 1800 reward points, how much money did he spend?
Answer:
He earned 1800 reward points for 600 dollars
Step-by-step explanation:
Given the statement: Omar has a new credit card. He earns 300 reward points for every 100 dollars he spends. If Omar earned 1800 reward points.
Unit rate are expressed as a quantity of 1, such as 3 feet per second or 4 miles per hour, they are called unit rates.
Earn 300 reward point for every 100 dollars.
⇒ unit rate per reward = [tex]\frac{100}{300}[/tex] dollars
we have to find how many dollars he earned for 1800 points.
[tex]Number of dollars = unit rate \times 1800[/tex]
= [tex]\frac{100}{300} \times 1800 = 600[/tex]
Therefore, he earned 1800 reward points for 600 dollars
Answer:
$600 money Omar spends .
Step-by-step explanation:
As given
Omar has a new credit card.
He earns 300 reward points for every 100 dollars he spends.
i.e
300 reward points for every 100 dollars .
Let us assume that the Omar earned 1800 reward points when he spends x money.
Than the equation becomes
[tex]x = \frac{1800\times 100}{300}[/tex]
[tex]x = \frac{1800}{3}[/tex]
x = $600
Therefore $600 money Omar spends .

Willis drove 239.82 miles in 4.2 hours at a constant speed. How long would it take him to drive 445.38 miles at the same speed?
Answer:
7.8 hours.
Step-by-step explanation:
We have been given that Willis drove 239.82 miles in 4.2 hours at a constant speed.
First of all let us find out speed at which Willis traveled 239.82 miles using speed formula.
[tex]\text{Speed}=\frac{\text{Distance}}{\text{Time}}[/tex]
[tex]\text{Speed}=\frac{239.82\text{ miles}}{4.2\text{ hours}}[/tex]
[tex]\text{Speed}=57.1\frac{\text{ miles}}{\text{ hour}}[/tex]
Now let us find time taken by Willis to cover a distance of 445.38 miles.
[tex]\text{Time}=\frac{\text{Distance}}{\text{Speed}}[/tex]
[tex]\text{Time}=\frac{445.38\text{ miles}}{57.1\frac{\text{ miles}}{\text{ hour}}}[/tex]
[tex]\text{Time}=\frac{445.38\text{ miles}}{57.1}\times\frac{\text{hour}}{\text{ miles}}}[/tex]
[tex]\text{Time}=\frac{445.38}{57.1}\times\text{hour}[/tex]
[tex]\text{Time}=7.8\text{ hour}[/tex]
Therefore, it will take Willis 7.8 hours to drive 445.38 miles at the same speed.
There are 8 blue marbles and 7 red marbles in a bag. Julie pulls two marbles at random from the bag first. What is the probability that she first pulls a blue marble and then a red marble?
Answer:
either a ratio 8;7. or a percentage of 53% for picking the blue marble first i think and a 50/50 chance if you keep that blue marble out.
Step-by-step explanation:
Answer: [tex]\frac{4}{15}[/tex]
Step-by-step explanation:
Given: Number of blue marbles = 8
Number of red marbles = 7
Total number of marbles = 8+7=15
Now, the probability that she first pulls a blue marble is given by :-
[tex]P(B)=\frac{\text{blue marbles}}{\text{Total marbles}}\\\\=\frac{8}{15}[/tex]
Now, total marbles left in bag = 15-1=14
Now, the probability that she second pulls a red marble is given by :-
[tex]P(B)=\frac{\text{red marbles}}{\text{Total marbles left}}\\\\=\frac{7}{14}=\frac{1}{2}[/tex]
Thus, the probability that she first pulls a blue marble and then a red marble is given by :-
[tex]P(B)\timesP(R)=\frac{8}{15}\times\frac{1}{2}=\frac{4}{15}[/tex]

According to the AAS corollary, which of the following sets of relationships can be used to show that VRT and STR are congruent?
A.STR VRT and VR ST
B. TVR SRT and VTR RTS
C. SRT VTR and VT SR
D. RST TVR and STR VRT
The AAS corollary from geometry states that two triangles are congruent if two angles and the non-included side of one triangle are equal to the two angles and the non-included side of another triangle. Because of this, option C is the correct answer as it confirms that triangles VRT and STR have these equal parts.
Explanation:The subject here is the Angle-Angle-Side (AAS) corollary in mathematics, specifically geometry. According to the AAS corollary, two triangles are congruent (identical in form) if two angles and the non-included side of one triangle are equal to the corresponding two angles and the non-included side of another triangle. Therefore, the set of relationships that confirm VRT and STR are congruent would be the one that shows that two angles and the non-included side in triangle VRT are equal to those in triangle STR.
Based on this, option C. SRT VTR and VT SR is the correct answer. It shows that angles SRT and VTR are equal (two angles) and sides VT and SR are equal (one side). Since the side (VT or SR) is not included between the two mentioned angles (SRT or VTR), this satisfies the conditions of the AAS corollary and can be used to show that triangles VRT and STR are congruent.

At a horse show, ribbons are awarded for first, second, third, and fourth places. There are 16 horses in the show. How many different arrangements of four horses are possible?
Answer:
43680 different arrangements are possible.
Step-by-step explanation:
The total number of horses are :16
We have to find different arrangement of four horses
Since, we have to find arrangements means we will use permutation
So, the required arrangement will be:
[tex]^{16}P_4[/tex]
Now, using: [tex]^{n}P_r=\frac{n!}{(n-r)!}[/tex]
Here, n= 16 and r=4 on substituting the values we get:
[tex]^{16}P_4=\frac{16!}{(16-4)!}[/tex]
[tex]\Rightarrow \frac{16!}{12!}[/tex]
[tex]\Rightarrow \frac{16\cdot 15\cdot 14\cdot 13\cdot 12!}{12!}[/tex]
Cancel out the common term that is 12! we get:
[tex]16\cdot 15\cdot 14\cdot 13[/tex]
After simplification we get: 43680
Hence, 43680 different arrangements are possible.
In the triangle below, what is cos B?
Answer:
[tex]\text{cos}(B)=\frac{c}{a}[/tex]
Step-by-step explanation:
We have been given a triangle. We are asked to find [tex]\text{cos}(B)[/tex].
We know that cosine relates adjacent side of a right triangle to its hypotenuse.
[tex]\text{cos}=\frac{\text{Adjacent}}{\text{Hypotenuse}}[/tex]
We can see that side AB is adjacent side and CB is hypotenuse of our given right triangle.
[tex]\text{cos}(B)=\frac{AB}{CB}[/tex]
[tex]\text{cos}(B)=\frac{c}{a}[/tex]
Therefore, our required value is [tex]\text{cos}(B)=\frac{c}{a}[/tex]

A general proof for this would be that since Angle A + Angle F + Angle E = 180°, and each of these angles is congruent to some angle inside of Triangle CGH; that CGH would equal 180°.
Interior angles of triangles = 180°, which is common knowledge; unfortunately this isn't an answer choice - so we use the above proof.
F ~= C
A ~= H
E ~= G
So, Angles A and H are congruent would be the correct solution.
Find (g - f)(x). f(x) = 1/x g(x) = x2 + 2x -5

B. 1/x+x^2+2x-5
C. x^2+2x-5-1/x
D. 1/x +x^2-5
Answer:
C) [tex]g(x)-f(x)=x^2 + 2x -5-\frac{1}{x}[/tex]
Step-by-step explanation:
[tex]f(x) = \frac{1}{x} \ g(x) = x^2 + 2x -5[/tex]
To find (g-f)(x) , we need to calculate g(x) - f(x)
WE know f(x) = 1/x and g(x) = x^2 + 2x -5
Plug in g(x) and f(x) and then subtract
[tex]g(x)-f(x)=x^2 + 2x -5- (\frac{1}{x})[/tex]
All are unlike terms so we cannot combine like terms
[tex]g(x)-f(x)=x^2 + 2x -5-\frac{1}{x}[/tex]
In order to find (g - f)(x), you need to subtract f(x) from g(x). The correct subtraction results in the expression x^2+2x-5-1/x, corresponding with answer choice C.
Explanation:The question asks you to calculate (g - f)(x) where f(x) = 1/x and g(x) = x^2 + 2x -5. This entails finding the difference between g(x) and f(x).
Firstly, write out g(x) and f(x):
g(x) = x^2 + 2x - 5f(x) = 1/xSecondly, subtract f(x) from g(x):
g(x) - f(x) = (x^2 + 2x - 5) - (1/x)
This simplifies to: g(x) - f(x) = x^2 + 2x - 5 - 1/x
Therefore, the correct answer is C. x^2+2x-5-1/x

A knitting machine used a total of 457,500 meters of yarn to make 100 cardigans and 200 pullovers yesterday. The machine takes the same length of yarn to make 21 pullovers as to make 20 cardigans.
What length of yarn does the machine use to make cardigans and pullovers?
The machine uses ______meters of yarn per cardigan and uses ______
meters per pullover.
Answer:
The machine uses 1575 meters of yarn per cardigan and uses 1500 meters per pullover.
Step-by-step explanation:
Let P be yarn needed by machine for each pullover and C be yarn needed by machine for each Cardigan.
We are told that the machine takes the same length of yarn to make 21 pullovers as to make 20 cardigans. We can represent this information as:
[tex]20C=21P...(1)[/tex]
The machine used a total of 457,500 meters of yarn to make 100 cardigans and 200 pullovers. We can represent this information as:
[tex]200P+100C=457,500...(2)[/tex]
Let us solve our system of equations using substitution method.
From equation (1) we will get,
[tex]C=\frac{21P}{20}[/tex]
Upon substituting this value in equation (2) we will get,
[tex]200P+100(\frac{21P}{20})=457,500[/tex]
[tex]200P+5*21P=457,500[/tex]
[tex]200P+105P=457,500[/tex]
[tex]305P=457,500[/tex]
[tex]P=\frac{457,500}{305}[/tex]
[tex]P=1500[/tex]
Therefore, the machine uses 1500 meters of yarn per pullover.
Upon substituting P=1500 in equation (1) we will get,
[tex]20C=21*1500[/tex]
[tex]20C=31,500[/tex]
[tex]C=\frac{31,500}{20}[/tex]
[tex]C=1575[/tex]
Therefore, machine uses 1575 meters of yarn per cardigan.
