4) At lunch, you volunteer to go out to buy sandwiches. You get 6 chicken sandwiches and 6
ham sandwiches for $30. Later that afternoon, everyone gets hungry again. You go to the same
shop and buy 4 chicken sandwiches and 8 ham sandwiches for $30.60 What was the price of
each sandwich?
(assume tax is included in the totals)
Answer:
Cost chicken sandwich is $2.35
Cost of ham sandwich is $2.65
Step-by-step explanation:
Let the cost of chicken sandwiches = c
Let the cost of ham sandwiches = h
Number of chicken sandwiches = 6
Number of ham sandwiches = 6
So,
6c + 6h = 30 ------ (I)
Number of chicken sandwiches on second round = 4
Number of ham sandwiches on second round = 8
4c + 8h = 30.6 ------ (ii)
We have two sets of of equations, let us solve;
6c + 6h = 30 ------ (I)
4c + 8h = 30.6 ------ (ii)
From equation i, divide through by 6 to give;
c + h = 5
c = 5 - h
Input into equation ii;
4(5 - h) + 8h = 30.6
20 - 4h + 8h = 30.6
4h = 30.6 - 20
4h = 10.6
h = 2.65
Price of ham sandwich = $2.65
Now, for the chicken sandwich;
c = 5 - 2.65 = $2.35
Cost chicken sandwich is $2.35
Cost of ham sandwich is $2.65

6b.) Hence, or otherwise, evaluate g(f(3))
Answer:
-25
Step-by-step explanation:
g(f(3))= g(-5)
=4(-5)-5
= -20-5
=-25
Answer:
[tex]g(f(3))=-25[/tex]
Step-by-step explanation:
We have the two functions: [tex]f(x)=-2x+1[/tex] and [tex]g(x)=4x-5[/tex].
And we want to evaluate [tex]g(f(3))[/tex].
So, let's evaluate f(3) first. Substitute 3 into f(x). This yields:
[tex]f(3)=-2(3)+1[/tex]
Multiply and add:
[tex]f(3)=-6+1=-5[/tex]
So, our expression is now:
[tex]g(f(3))\Rightarrow g(-5)[/tex]
Substitute -5 for g(x):
[tex]g(-5)=4(-5)-5[/tex]
Multiply and subtract:
[tex]g(-5)=-20-5=-25[/tex]
Therefore:
[tex]g(f(3))=-25[/tex]
Find the values of x and y. The diagram is not to scale.
Answer:
51+x-5+y-6=180
x+y=180-51+5+6
X+y=140
Answer x=77 y=63
(those 2 lines with the arrows are perpendicular so their angles are the same 72° and (x-5)=77-5= 72°)
The values of x and y are 77 and 63 respectively.
What is Angle?Angle is defined as the figure formed by two lines or rays which has a common point of intersection where the angle is formed.
Sum of the interior angles of a triangle is supplementary.
That is three angles (y - 6)°, 72° and an unknown angle is supplementary.
We have two parallel lines given and a transversal line intersects the parallel lines.
So the unknown angle of the triangle and the angle 51° are alternate interior angles and are thus equal.
So the third angle of the triangle = 51°
(y - 6) + 72 + 51 = 180
y - 6 + 123 = 180
y + 117 = 180
y = 63
The angles (x - 5)°, 51° and (y - 6)° are supplementary.
(x - 5) + 51 + (y - 6) = 180
x - 5 + 51 + 63 - 6 = 180
x + 103 = 180
x = 77
Hence the value of x is 77 and the value of y is 63.

Maya bought a dozen specialty donuts at the bakery for $18. She purchased a mixture of frosted donuts for $2 each, glazed donuts for $1 each, and custard filled donuts for $5 each. If Maya purchased twice as many frosted donuts as custard filled donuts, how many of each type of donut did she buy? Variables: mixture of frosted donuts X y = glazed donuts Z = custard filled donuts System: System in standard form:
Answer:
The quantity of frosted donuts = 2
The quantity of glazed donuts = 9
The quantity of custard filled donuts = 1
Step-by-step explanation:
Let the quantity of frosted donuts = [tex]x[/tex]
Let the quantity of glazed donuts = [tex]y[/tex]
Let the quantity of custard filled donuts = [tex]z[/tex]
As per question statements, following equations can be made:
[tex]x+y+z=12......(1)\\2x+y+5z=18.....(2)\\x=2z ...... (3)[/tex]
Putting [tex]x=2x[/tex] in (1) and (2):
[tex]y+3z=12 .... (4)\\y+9z=18 .... (5)[/tex]
Subtracting (4) from (5):
[tex]6z=6\\\Rightarrow z =\bold{1}[/tex]
By equation (3):
[tex]x=\bold{2}[/tex]
By equation (1):
[tex]y=\bold{9}[/tex]
Therefore, the answers are:
The quantity of frosted donuts = 2
The quantity of glazed donuts = 9
The quantity of custard filled donuts = 1
what is y + 1=x in slope intercept form?
Answer:
y = x - 1

The ___________________ of a right triangle are the two sides that make up the right angle.
Answer:
a and b are the "legs" of the triangle, which are the two sides that make up the 90 degree angle. c is the "hypotenuse" of the triangle, and is the side of the triangle that is opposite the right angle (another way to say a 90º angle is "right angle"). The hypotenuse is also the longest side of the right triangle.

help im stuck pls -- Refer to the table above. Determine the percent of all voters that did not vote Republican or Democrat but voted "other" instead. Round your answer to the nearest tenth of a percent.
Answer:
9.9%
Step-by-step explanation:
Well, you would just divide the "other" category and the "total" category and then move the decimal over 2 spaces, because you need to multiply by 100 to turn your answer into a percent, so:
[tex]\frac{222}{2222} =0.09999...\\[/tex]
Then once you multiply by 100, or move the decimal to the left 2 spaces, it becomes:
9.9%, which could be rounded to 10% or 9%.

A municipal bond service has three rating categories (A, B, and C). Suppose that in the past year, of the municipal bonds issued throughout the United States, 70% were rated A, 20% were rated B, and 10% were rated C. Of the municipal bonds rated A, 50% were issued by cities, 40% by suburbs, and 10% by rural areas. Of the municipal bonds issued B, 60% were issued by cities, 20% by suburbs, and 20% by rural areas. Of the municipal bonds rated C, 90% were issued by cities, 5% by suburbs, and 5% by rural areas. a. If a new municipal bond is to be issued by a city, what is the probability that it will receive an A rating? b. What proportion of municipal bonds are issued by cities? c. What proportion of municipal bonds are issued by suburbs?
Answer:
(a) The probability that the new municipal bond issued will receive an A rating given that it was issued by a city is 0.196.
(b) Thus, the probability of municipal bonds issued by suburbs is 0.325.
Step-by-step explanation:
The data provided is as follows:
P (A) = 0.70
P (B) = 0.20
P (C) = 0.10
P (c | A) = 0.50
P (s | A) = 0.40
P (r | A) = 0.10
P (c | B) = 0.60
P (s | B) = 0.20
P (r | B) = 0.20
P (c | C) = 0.90
P (s | C) = 0.05
P (r | C) = 0.05
(a)
The Bayes' theorem states that the conditional probability of an event Y[tex]_{i}[/tex] given that another event X has already occurred is:
[tex]P(Y|X)=\frac{P(X|Y)P(Y)}{\sum\limits_{i} {P(X|Y_{i})P(Y_{i})}}[/tex]
Compute the probability that the new municipal bond issued will receive an A rating given that it was issued by a city as follows:
[tex]P(A|c)=\frac{P(c|A)P(A)}{P(c|A)P(A)+P(c|B)P(B)+P(c|C)P(C)}[/tex]
[tex]=\frac{(0.50\times 0.70)}{(0.50\times 0.70)+(0.60\times 0.20)+(0.10\times 0.90)}\\\\=\frac{0.35}{0.56}\\\\=0.196[/tex]
Thus, the probability that the new municipal bond issued will receive an A rating given that it was issued by a city is 0.196.
(b)
The law of total probability states that:
[tex]P(X)=\sum\limits_{i} {P(X|Y_{i})}[/tex]
Compute the probability of municipal bonds issued by suburbs as follows:
[tex]P(s)=P(s|A)P(A)+P(s|B)P(B)+P(s|C)P(C)[/tex]
[tex]=(0.40\times 0.70)+(0.20\times 0.20)+(0.10\times 0.05)\\\\=0.28+0.04+0.005\\\\=0.325[/tex]
Thus, the probability of municipal bonds issued by suburbs is 0.325.
