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

A roofs length is 4 feet less than twice its width algebraic expression
Answer:
2x - 4
Step-by-step explanation:
So first the length is 4 feet less than twice the width meaning that to find the length you subtract twice the width ( 2x ) minus 4.
Thus it becomes 2x - 4

Answer:
D
Step-by-step explanation:
in order to compare all the numbers, we have to express them all in the same form to compare them easily, we will choose to convert all of them to decimal form:
20% = 20/100 = 0.2
1/3 = 0.33333
3.4 x 10⁻¹ = 0.34
-5/2 = -2.5
comparing all these numbers, it is now clear that in decending order:
0.34 > 0.33333 > 0.2 > -2.5
or
3.4 x 10⁻¹ > 1/3 > 20% > -5/2

A set of 200 scores is normally distributed with a mean of 60 and . a standard deviation of 12. a, What are the z-scores corresponding to the. raw scores .of 76, 38; and 50
Answer:
Z scores for:
a) 76 = 1.33333
b) 38 = -1.83333
c) 50 = -0.83333
Step-by-step explanation:
Z score formula is:
z = (x-μ)/σ where
x is the raw score
μ is the population mean
σ is the population standard deviation.
Mean = 60
Standard deviation = 12.
a) 76
z = (x-μ)/σ
z = 76 - 60/12
z score = 1.33333
b) 38
z = (x-μ)/σ
z = 38 - 60/12
z score = -1.83333
c) 50
z = (x-μ)/σ
z = 50 - 60/12
z score = -0.83333
What would the value of X be?
Answer:

Step-by-step explanation:
The right arrow symbol used to show the transition from a point to its image after a transformation is not contained within the Equation Editor. If such a symbol is needed, type "RightArrow." For example: P(0, 0) RightArrow P′(1, 2).
Triangle ABC has coordinates
A (1,4);B(3,−2); and C(4,2).
Find the coordinates of the image
A'B'C' after a reflection over the x-axis.
Given:
Vertices of triangle ABC are A (1,4), B(3,−2) and C(4,2).
Triangle ABC reflected over the x-axis to get the triangle A'B'C'.
To find:
The coordinates of the image A'B'C'.
Solution:
If a figure reflected over the x-axis, then rule of transformation is
[tex](x,y)\to (x,-y)[/tex]
Now, using this rule, we get
[tex]A(1,4)\to A'(1,-4)[/tex]
[tex]B(3,-2)\to B'(3,2)[/tex]
[tex]C(4,2)\to C'(4,-2)[/tex]
Therefore, the coordinates of the image A'B'C' after a reflection over the x-axis are A'(1,-4), B'(3,2) and C'(4,-2).

A large container holds 8 gallons of water. It begins leaking at a constant rate. After 16 minutes, the container has 7 gallons of water left. How many minutes will it take for the container to go from full to empty
Answer:
128 minuter, or 2 hours 8 minutes.
Step-by-step explanation:
So, every 16 minutes, 1 gallon leaks. that mean that we use 8x16, which is 128. now, we make them into hours, which is 2 hours, 8 minutes.
Evaluate the expression.
8 x -9 = 6 x -8

Please ASAP What is the remainder when x3−2x2−51x−108 is divided by x−2?
Answer:
[tex]-210[/tex]
Step-by-step explanation:
We have the function:
[tex]f(x)=x^3-2x^2-51x-108[/tex]
And we want to find the remainder when it is divided by [tex](x-2)[/tex].
We can use the Polynomial Remainder Theorem, where if we have a function [tex]f(x)[/tex] divided by a binomial [tex](x-a)[/tex], then our remainder will be [tex]f(a)[/tex].
Here, our divisor is [tex](x-2)[/tex], so our a is 2.
Therefore, our remainder will be [tex]f(2)[/tex]. Let's substitute this for x. This yields:
[tex]f(2)=(2)^3-2(2)^2-51(2)-108[/tex]
Evaluate. Do the exponents:
[tex]f(2)=8-2(4)-51(2)-108[/tex]
Multiply:
[tex]f(2)=8-8-102-108[/tex]
Subtract:
[tex]f(2)=-210[/tex]
So, our remainder is -210.
And we're done!

Two dice are rolled. What is the probability that the sum of the numbers rolled is either 4 or 9? Express your answer as a fraction in lowest terms or a decimal rounded to
the nearest millionth.
Answer:
1/4
Step-by-step explanation:
There are 36 possible combinations. Of those 36, the ones that add up to either 6 or 9 are:
1+5, 2+4, 3+3, 4+2, 5+1, 3+6, 4+5, 5+4, 6+3
There are 9 combinations that add up to either 6 or 9. So the probability is 9/36, or 1/4.
