A local food truck specializes in gourmet grilled cheese sandwiches. Each month, the owners of the truck have a constant total of $7,900 in expenses (salaries, truck loan, etc.) and it costs $1.70 per sandwich to make each sandwich. The food truck sells its sandwiches for $7.75 each.
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Fixed costs= $7,900
Unitary cost per sandwich= $1.7
Selling price per unit= $7.75
To calculate the break-even point in units and dollars, we need to use the following formula:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 7,900 / (7.75 - 1.7)
Break-even point in units= 1,306 sandwiches
Break-even point (dollars)= fixed costs/ contribution margin ratio
Break-even point (dollars)= 7,900 / (6.05 / 7.75)
Break-even point (dollars)= $10,120

Which statements are true about the ordered pair (−1, 5) and the system of equations?
Answer:
Option D is correct answer.
Step-by-step explanation:
We are given the system of equations:
[tex]x+y=4\\x-y=-6[/tex]
Solving the system of equations to find values of x and y
Let:
[tex]x+y=4--eq(1)\\x-y=-6--eq(2)[/tex]
Adding both equations to find value of x
[tex]x+y=4\\x-y=-6\\------\\2x=-2\\x=\frac{-2}{2}\\x=-1[/tex]
So, we get value of x: x=-1
Now, putting value of x: x=-1 into equation 1 to find value of y
[tex]x+y=4\\Putx=-1\\-1+y=4\\y=4+1\\y=5[/tex]
So, we get value of y: y=5
The ordered pair will be: (-1,5)
So, Option D: The ordered pair(-1,5) is a a solution to the system of equations because it makes both equations true is correct choice.
Checking:
Put x=-1 and y=5 in equation 1
[tex]x+y=4\\-1+5=4\\4=4\:True[/tex]
Put x=-1 and y=5 in equation 2
[tex]x-y=-6-1-5=-6\\-6=-6\:\:\:True[/tex]
So, both equations are true.
Therefore, Option D is correct answer.

Jake rewrites the expression 81x4 – 1 as a difference of squares so he can factor it. Which answer choice shows how Jake could rewrite the expression?
Answer: (9x^2)^2 -1^2
Step-by-step explanation:
Jake rewrite the expression as,
⇒ (3x - 1) (3x + 1) (9x² + 1)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 81x⁴ - 1
And, Jake rewrites the expression as a difference of squares so he can factor it.
Now, We can rewrite the expression as;
⇒ 81x⁴ - 1
⇒ (9x²)² - 1²
⇒ (9x² - 1) (9x² + 1)
⇒ ((3x)² - 1²) (9x² + 1)
⇒ (3x - 1) (3x + 1) (9x² + 1)

Lisa is buying a computer for $1,500. The sales tax rate is 8.5%. Which expression should be used to calculate t, the total cost for the computer including tax?
Answer:
t=$1627.5Step-by-step explanation:
Step one:
given data
price of computer= $1500
sales tax= 8.5%
Step two
Let us compute the amount in tax
tax= 8.5/100*1500
=0.085*1500
=$127.5
Let the total cost be t
hence
t=1500+0.085*1500
t=1500+127.5
t=$1627.5

find the equation of a line which passes through (2 4) with a slope of ½
Answer:
The equation of the straight line is x - 2y +6 =0
Step-by-step explanation:
Explanation:-
Given a point ( 2, 4) and slope m = [tex]\frac{1}{2}[/tex]
The equation of the straight line passing through the point and having slope 'm'
y - y₁ = m ( x - x₁)
y - 4 = [tex]\frac{1}{2}[/tex] ( x - 2)
2( y -4) = ( x-2)
2 y - 8 = x -2
x - 2 y - 2 + 8 =0
x - 2y + 6 =0
The equation of the straight line is x - 2y +6 =0
The answer is:
y = 1/2x + 5
Work/explanation:
Since I have a point and the slope, I will write the equation in point slope form.
Point slope is
[tex]\sf{y-y_1=m(x-x_1)}[/tex]
where m = slope and (x₁, y₁) is a point on the line
Plug in the data
[tex]\sf{y-4=\dfrac{1}{2}(x-2)}[/tex]
Now let's simplify to slope intercept
[tex]\large\begin{gathered}\sf{y-4=\dfrac{1}{2}x+1}\\\sf{y=\dfrac{1}{2}x+1+4}\\\sf{y=\dfrac{1}{2}x+5}\end{gathered}[/tex]
Hence, the equation is y = 1/2x + 5.What is the calculated interest for $650, with a 3% simple annual interest rate, after 4 years?

The base of 40-foot ladder is 8 feet from the wall. How high is the ladder on the wall (round to the nearest foot)
Given:
The base of 40-foot ladder is 8 feet from the wall.
To find:
How high is the ladder on the wall (round to the nearest foot).
Solution:
Ladder makes a right angle triangle with wall and ground.
We have,
Length of ladder (hypotenuse)= 40 foot
Base = 8 foot
We need to find the perpendicular to get the height of the ladder on the wall.
Let h be the height of the ladder on the wall.
According to the Pythagoras theorem,
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
[tex](40)^2=(8)^2+(h)^2[/tex]
[tex]1600=64+h^2[/tex]
[tex]1600-64=h^2[/tex]
[tex]1536=h^2[/tex]
Taking square root on both sides.
[tex]\pm \sqrt{1536}=h[/tex]
[tex]\pm 39.1918358=h[/tex]
Height cannot be negative. Round to the nearest foot.
[tex]h\approx 39[/tex]
Therefore, the height of the ladder on the wall is 39 foot.

E
Which postulate or theorem establishes that the triangles are similar?
Answer:
AA similarity
Step-by-step explanation:
Your question is not well presented.
See attachment
Given
Triangles ABC and DBE
Required
Which postulate supports the similarities of ABC and DBE
At the first transformation (180 degrees rotation) both triangles maintain SSS and AAA relationships. i.e Side-Side-Side and Angle-Angle-Angle
This is so because rotations do not alter the side lengths; neither does it alter the angles.
When the second transformation (dilation) takes place, the lengths of both triangles ABC and DBE become different because dilation alters side lengths.
However, angle measurements remain unaltered.
Hence, AAA similarity answers the question
can a triangle be made with side lengths of 1, 2, and 4 plsss
NO IT CANNOT BE MADE
Step-by-step explanation:
Since, The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
A truck driver has a route that takes him 125 miles each way each day that he works. If he makes 15 roundtrips on this route per month, how many miles does he drive the truck per month?
Answer: 3,750 miles
Step-by-step explanation:
Route takes him 125 miles each way so in a day he travels:
= 125 + 125
= 250 miles
He made 15 roundtrips so total miles is:
= 15 * 250
= 3,750 miles
