We have to calculate the maximum common divisor of these 3 numbers in order to know what is the maximum ammount of sandwiches they can make.
We can list the factors of each number:
72: 1, 2, 3, 4, 6, 8, 12, 18, 24, 36, 72.
48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48.
96: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48, 96.
To calculate this factors, we start by dividing by 2 and 3, and so on, and checking if the result is a whole number. If it is, the denominator is a factor.
The maximum common divisor is 24, so they can make 24 sandwichs, each one with 72/24=3 slices of turkey, 48/24=2 slices of cheese and 96/24=4 slices of tomatoes.
George's boxes
He has bought boxes at different prices.
3 boxes at $3.50 and 4 boxes at $3.00.
The cost of the first group of boxes is 3 boxes x 3.50 $/boxes = $10.50.
The cost of the second group is 4 boxes x 3.00 $/boxes = $12.
Then, if we add the cost, it is 10.50 + 12 = $22.50.
If we write it in the blanks we have:
3 boxes * 3.50 = 3 * 3.50
4 boxes * 3.00 = 4 * 3.00
(3 * 3.50) + (4 * 3.00) = 22.50
(underlined is what goes in the blanks)
Stacy loaned Robert $21,370 at an interest rate of 10 % for 171 days. How much will Robert pay Stacy at the end of 171 days? Roundyour answer to the nearest cent. Note: Assume 365 days in a year and 30 days in a month.
The simple interest formula is :
[tex]A=P(1+rt)[/tex]where A is the future amount
P is the principal amount
r is the rate of interest
and
t is the time in years
From the problem, we have :
P = $21,370
r = 10% or 0.10
t = 171 days or 171/365 year
Using the formula above :
[tex]\begin{gathered} A=21370(1+0.10\times\frac{171}{365}) \\ A=22371.17 \end{gathered}[/tex]The answer is $22,371.17

Based only on the information given in the diagram, which congruencetheorems or postulates could be given as reasons why ACDE=A OPQ?Check all that apply.СA. ASAB. HAC. SASD. LLE. HLF. AAS
The postulates of congruence for right triangles are
• Hypotenuse-Leg Theorem.
,• Leg-Leg Theorem.
,• Leg-Acute Angle Theorem.
,• Hypotenuse-Acute Angle Theorem.
In this case, we know that sides CE and OQ are congruent. (hypotenuses are congruent)
Angle C is congruent to angle O.
Angle E is congruent to angle Q.
To demonstrate the congruence between triangles we can use Hypotenuse-Acute Angle Theorem since they are congruent between triangles.
We can also use Hypotenuse-Leg Theorem because we have corresponding legs and hypotenuses congruent.
The hypotenuse-acute angle theorem states that two right triangles are congruent if they have congruent hypotenuse and one corresponding pair of acute angles congruent.
The hypotenuse-leg theorem states that two right triangles are congruent if they have congruent hypotenuse and one corresponding pair of congruent legs.
Therefore, the right choices are B and E.1.1.22Question HelpAngie and Kenny play online video games. Angie buys 1 software package and 3 months of game play, Kenny buys 2 software packages and 2 months of gameplay. Each software package costs $25. If their total cost is $125, what is the cost of one month of game play?
We have a system of linear equations:
Let S be the price of software package and M be the price of the month of game play.
Angie buys 1 software package and 3 months of gameplay, while Kenny buys 2 software packages and 2 months of game play. The total cost for them is $125.
We can write this as:
[tex]\begin{gathered} (1S+3M)+(2S+2M)=125 \\ 3S+5M=125 \end{gathered}[/tex]We also know that each software package cost $25. This can be written as:
[tex]S=25[/tex]We can replace this last equation in the first one, and calculate M:
[tex]\begin{gathered} 3S+5M=125 \\ 3(25)+5M=125 \\ 75+5M=125 \\ 5M=125-75 \\ 5M=50 \\ M=\frac{50}{5} \\ M=10 \end{gathered}[/tex]The cost of one month of game play is $10.
Which of the following describes the transformation of the graph y = x 2 in graphing y = -x 2 - 5?reflect over the x-axis and shift down 5reflect over the y-axis and shift down 5reflect over the x-axis and shift left 5
The parent function of the graph is,
[tex]y=x^2[/tex]The transformed image of the graph is,
[tex]y_1=-x^2-5[/tex]Let us sketch out the graph of both the parent function and the transformed function.
From the image above, the parent function, y=x² was first reflected over the y-axis. Therefore, the transformation resulted into y= -x² .
After that, it was now shifted down by 5 units, which now resulted into
[tex]y=-x^2-5[/tex]Hence, the correct answer is B(Second option), which is the parent function was reflected over the y-axis and shifted downward by 5 units.

What is the difference between area and perimeter of a two-dimension figure? What is the difference in the area formulas for a parallelogram and triangle
The perimeter is a measure of the distance around the shape. This means that to find the perimeter we usually are going to add the lenghts of the sides of the figure (the circle is an exception to that rule since this is a curve figure).
The are is a measure of the space inside the figure. This means that to find the area we usually are going to multiply the lenghts of the sides of the figure to get the area.
Now the area of a triangle is given as:
[tex]A=\frac{1}{2}bh[/tex]whereas the area of a paralelogram is given by:
[tex]A=bh[/tex]From this we notice that the area of the triangle is half the area of a parallelogram.

step by step on how to solve 3/4 - 1/2 × 7/8
EXPLANATION
Given the following operation:
3/4 - 1/2*7/8
First, let's solve 1/2*7/8:
Multiply fractions: a/b* c/d = (a*c)/(b*d)
[tex]=\frac{1\cdot7}{2\cdot8}[/tex]Multiply the numbers: 1*7 = 7
[tex]=\frac{7}{2\cdot8}[/tex]Multiply the numbers 2*8=16
[tex]=\frac{3}{4}-\frac{7}{16}[/tex]Now, we need the Least Common Multiplier of 4, 16:
The LCM of a, b is the samllest positive number that is divisible by both a and b:
Prime factorization of 4:
4 divides by 2 ---> 4= 2*2
2 is a primer number, therefore no further factorization is possible.
Prime factorization of 16:
Multiply each factor the greatest number of times it occurs in either 4 or 16
= 2*2*2*2
Multiply the numbers: 2*2*2*2 = 16
Adjust fractions based on LCM
For 3/4: multiply the denominator and numerator by 4
[tex]\frac{3}{4}=\frac{3\cdot4}{3\cdot4}=\frac{12}{16}[/tex][tex]=\frac{12}{16}-\frac{7}{16}[/tex]Since the denominators are equal, combine the fractions:
[tex]=\frac{12-7}{16}[/tex]Subtract the numbers: 12-7 = 5
[tex]=\frac{5}{16}[/tex]Solve the following system of equations for all three variables.-8x – 3y + 5z = -2X-2y – 5z = -94x + 7y + 5z = 4
In order to solve this system of equations, first let's add the second equation to the first and third ones:
[tex]\begin{gathered} \begin{cases}-8x-3y+5z+(x-2y-5z)=-2+(-9) \\ 4x+7y+5z+(x-2y-5z)=4+(-9)\end{cases} \\ \begin{cases}-7x-5y=-11 \\ 5x+5y=-5\end{cases} \end{gathered}[/tex]Now, adding the two resulting equations, we have:
[tex]\begin{gathered} -7x-5y+(5x+5y)=-11+(-5) \\ -2x=-16 \\ x=8 \\ \\ 5x+5y=-5 \\ 40+5y=-5 \\ 5y=-45 \\ y=-9 \\ \\ x-2y-5z=-9 \\ 8+18-5z=-9 \\ -5z=-35 \\ z=7 \end{gathered}[/tex]So the solution for this system is x = 8, y = -9 and z = 7.

Amount of $28,000 is borrowed for nine years at 3.25 interest, compounded annually. If the loan is paid in full at the end of that period, how much must be paid back?Round your answer to the nearest dollar$=
Given:
Principal amount = $28,000
Time period = 9 years
Interest rate = 3.25
Required:
Find the total amount at the end of the period.
Explanation:
The amount formula when the interest is compounded annually is given by the formula:
[tex]A=P(1+r)^{nt}[/tex]Where P =principal amount
r = rate of interest
T = time period
n = Number of time
Substitute the given values in the amount formula.
[tex]\begin{gathered} A=28,000(1+0.0325)^9 \\ A=28,000(1.33355) \\ A=37,339.51 \\ A=37,340 \end{gathered}[/tex]Final Answer:
Thus the amount after 9 years is $37,340.

So first of all we need to write an algebraic equation for Mike. We know that he bought 3 coffees and 1 doughnut. Then the total price of these things is:
[tex]3c+1d=3c+d[/tex]And we know that he had to pay $19 so this expression is equal to 19:
[tex]3c+d=19[/tex]Then the answer to question 14 is the second option.
Bob bought one coffee and one doughnut so the total cost of his purchase is:
[tex]c+d[/tex]We know that this cost is equal to $9 so we get:
[tex]c+d=9[/tex]And the answer to question 15 is the third option.
In question2 16 and 17 we need to find c and d. For this purpose we need to use the algebraic equations for Mike and Bob:
[tex]\begin{gathered} 3c+d=19 \\ c+d=9 \end{gathered}[/tex]Let's take the second equation and substract c from both sides:
[tex]\begin{gathered} c+d-c=9-c \\ d=9-c \end{gathered}[/tex]Now we substitute this expression in place of d in the first equation:
[tex]\begin{gathered} 3c+d=3c+(9-c)=19 \\ 3c+9-c=19 \\ 2c+9=19 \end{gathered}[/tex]Now we substract 9 from both sides:
[tex]\begin{gathered} 2c+9-9=19-9 \\ 2c=10 \end{gathered}[/tex]And we divide both sides by 2:
[tex]\begin{gathered} \frac{2c}{2}=\frac{10}{2} \\ c=5 \end{gathered}[/tex]Then the price of one coffee is $5 so the answer to question 16 is the third option.
Now we are going to take the equation for Bob and take c=5:
[tex]c+d=5+d=9[/tex]If we substract 5 from both sides we get:
[tex]\begin{gathered} 5+d-5=9-5 \\ d=4 \end{gathered}[/tex]Then the price of one doughnut is $4 and the answer to question 17 is the second option.
