By setting up an equation equating the cost of shipping with both Mailboxes Plus and United Packages, we determine that Mr. Molinari's package weighs 30 ounces.
Mailboxes Plus charges a flat rate of $5 plus $0.25 per ounce, while United Packages charges $2 plus $0.35 per ounce. Since the cost is the same for either service, we can equate the two expressions and solve for the weight of the package in ounces.
Let x represent the weight of the package in ounces. The cost for Mailboxes Plus is then $5 + $0.25x, and for United Packages, it is $2 + $0.35x. Setting these two expressions equal to each other, we get:
$5 + $0.25x = $2 + $0.35x
Now, we will solve for x:
Subtract $2 from both sides: $3 + $0.25x = $0.35xSubtract $0.25x from both sides: $3 = $0.35x - $0.25xCombine like terms: $3 = $0.10xDivide both sides by $0.10: $3 / $0.10 = xSimplify: 30 ounces = xTherefore, Mr. Molinari's package weighs 30 ounces.

3x+4y=-23
2y-x=-19
What is the solution (x,y) to the systems of equations above?
Final answer:
The solution to the system of equations 3x + 4y = -23 and 2y - x = -19, found using the elimination method, is (x, y) = (-61, -40).
Explanation:
To solve the system of equations 3x + 4y = -23 and 2y - x = -19, we can use the method of substitution or elimination. Let's use elimination to find the solution for (x, y).
Multiply the second equation by 2 to align the x terms: 2(2y - x) = 2(-19), which gives us 4y - 2x = -38.
Rewrite the equations to align like terms:
3x + 4y = -23
-2x + 4y = -38
Add the two equations together to eliminate y: (3x - 2x) + (4y + 4y) = -23 - 38, resulting in x = -61.
Substitute x back into the second original equation: 2y - (-61) = -19, which simplifies to 2y + 61 = -19.
Solve for y by subtracting 61 from both sides: 2y = -80, and then dividing by 2 gives us y = -40.
So, the solution to the system of equations is x = -61 and y = -40.

A student's cell phone plan has a monthly charge of $40 for 600 minutes of use and a $0.25/minute charge for each additional minute. Last month, the student talked on the phone for 790 minutes. Which of the following is the bill for the month?
We have to find the bill for this month.
Since, the student talked on phone for 790 minutes.
600 minutes are provided in a monthly charge of $40 and the remaining minutes are charged $0.25/minute.
So, 790 - 600 =190 minutes.
So, 190 minutes are minutes at $0.25/minute.
So, Cost applied on 190 minutes = [tex] 190 \times \$ 0.25 [/tex]
= 47.50
So, Total bill for 790 minutes =
Cost for 600 minutes + Cost for 190 minutes
= $40 + $47.50
= $87.50
So, the bill for the month is $87.50

A rectangular prism has a length of 312 inches, a width of 5 inches, and a height of 112 inches. What is the volume of the prism? Enter your answer in the box as a simplified mixed number or a decimal.
Answer:
The volume of the prism in the decimal form is 26.25 inches³ and [tex]26 \frac{1}{4}\ inches^{3}[/tex]
Step-by-step explanation:
Formula
Volume of a rectangular prism = Length × Breadth × Height
As given
A rectangular prism has a length of [tex]3 \frac{1}{2}[/tex]inches, a width of 5 inches, and a height of [tex]1 \frac{1}{2}[/tex] inches.
i.e
A rectangular prism has a length of [tex]\frac{7}{2}[/tex]inches, a width of 5 inches, and a height of [tex]\frac{3}{2}[/tex] inches.
[tex]Volume\ of\ a\ rectangular\ prism = \frac{7}{2}\times 5\times \frac{3}{2}[/tex]
[tex]Volume\ of\ a\ rectangular\ prism = \frac{7\times 5\times\times 3}{2\times 2}[/tex]
[tex]Volume\ of\ a\ rectangular\ prism = \frac{105}{4}[/tex]
In mixed number
[tex]Volume\ of\ a\ rectangular\ prism =26 \frac{1}{4}\ inches^{3}[/tex]
In decimal form
[tex]Volume\ of\ a\ rectangular\ prism = 26.25\ inches^{3}[/tex]
Therefore the volume of the prism in the decimal form is 26.25 inches³ and [tex]26 \frac{1}{4}\ inches^{3}[/tex]
Answer: [tex]26\dfrac{1}{4}\text{ inches}^3[/tex]
Step-by-step explanation:
Given : In a rectangular prism , length = [tex]3\dfrac{1}{2}\text{ inches}[/tex]
[tex]=\dfrac{3(2)+1}{2}=\dfrac{7}{2}\text{ inches}[/tex]
width = 5 inches
height= [tex]1\dfrac{1}{2}\text{ inches}=\dfrac{3}{2}\text{ inches}[/tex]
Now, the volume of the prism will be :-
[tex]V= l\times w\times h\\\\=\dfrac{7}{2}\times5\times\dfrac{3}{2 }\text{ inches}^3\\\\=\dfrac{105}{4}\text{ inches}^3\\\\=26\dfrac{1}{4}\text{ inches}^3[/tex]
Hence, the volume of the prism [tex]=26\dfrac{1}{4}\text{ inches}^3[/tex]

Johan takes out a 20-year mortgage at 4% to buy a house. When he looks at investing in 20-year, fixed-rate Treasuries, which of the following rates is most likely closest to the coupons on the Treasuries? Select the best answer from the choices provided. 2.2% 7.8% 3.9% 9.2%
Answer:
3.9%
Step-by-step explanation:
Investing in treasuries is often seeing as a risk free investment since it is sure that they will pay, but the rates are too low, when banks and other finnance corporations set up their mortages and other kinds of large loans interests rates they set them up higher than the fixed rate treasuries since otherwise it´d just be a better deal to put that money on treasuries than lending it to people.
How many triangles can be constructed with angles measuring 80 degrees 80 degrees and 40 degrees
Answer:
None
Step-by-step explanation:
The angles inside a triangle add to 180. If the angles are 80, 80 and 40, then they must add to 180 to form a triangle.
80+80+40 = 200
This can't be a triangle.

Graph the equation
5x+3y+62=30
Answer:
see below
Step-by-step explanation:
Subtract 62, then divide by -32 to put the equation into intercept form:
... x/(-6.4) + y/(-10 2/3) = 1
This tells you the x-intercept is -6.4, and the y-intercept is -10 2/3. A line through these two points is your graph.
