If you want to make more punch for more people and have it taste the same, how would you increase the amounts of each ingredient? For 8 people? For 12 people? If you wanted to taste more caramel syrup, how would you adjust the ratio of ingredients? If you wanted to taste more pumpkin spice, how would you adjust the ratio of ingredients? Make the punch with either more caramel syrup or more pumpkin spice and ask those you share it with to write a review of the new punch. Activity 2: Thanksgiving Painting Create a painting for Thanksgiving. In your painting be sure to include the following: 2 different shades of Orange Write the ratio of red to yellow that you used for each shade of orange. How did you know what to change in the ratio in order to create a different shade of the color? 2 different shades of Green Write the ratio of yellow to blue that you used for each shade of green What did you change about your first green to create the second color? A geometric shape Identify the shape and describe its properties. HELP PLEASE mark as brainlyest
Here, we have a recipe that serves 4 people in the given ratio below;
Cider to Caramel syrup to Pumpskin spice = 4:1/4:1
Now to make for 8 people, we simply will multiply what we had in the original recipe by 2 since it was for 4 people initially
So the punch ratio for 8 people will be;
8 cups of Apple Cider
1/2 cups Caramel syrup
2 teaspoons of Pumpskin spice
For 12 people, we simply multiply what we had initially for 4 people by 3. This will be;
12 cups of Apple Cider
3/4 cups of Caramel syrup
3 teaspoons of Pumpskin spice

Jill is packing a lunch to bring to school. There are 3 types of sandwiches to choose from and 4 types of fruit. For the drink, Jill has 2 options. How many different lunches can Jill pack?
To solve this problem, it is necessary to use the multiplication counting rule. It states that the total outcomes of two events a and b is the product of a and b, it means a*b.
In this case, the total outcomes is the product of the number of options for each event (sandwiches, fruits and drinks). This is 3*4*2.
[tex]3\cdot4\cdot2=24[/tex]There are 24 different lunches Jill can pack.
A larger pipe fills a water tank twice as fast as a smaller pipe. When both pipes are used, they fill the tank in 55 hours. If the larger pipe is left off, then how long would it take the smaller pipe to fill the tank?
For this exercise you need to use the Work-rate formula. This is:
[tex]\frac{t}{t_A}+\frac{t}{t_B}=1[/tex]Where:
- "t" is the time for the objects A and B together.
- The individual time for object A is:
[tex]t_A[/tex]- The individual time for object B is:
[tex]t_B[/tex]In this case, you can idenfity that:
[tex]\begin{gathered} t=55 \\ t_A=2t_B \\ _{} \end{gathered}[/tex]Substitute them into the formula:
[tex]\frac{55}{2t_B_{}_{}}+\frac{55}{t_B}=1[/tex]Now you must solve for:
[tex]t_B[/tex]You get that this is:
[tex]\begin{gathered} \frac{55+2(55)}{2t_B}=1 \\ \\ \frac{55+110}{2t_B}=1 \\ 165=(1)(2t_B) \\ \\ \frac{165}{2}=t_B_{} \\ \\ t_B=82.5 \end{gathered}[/tex]The answer is: It takes the smaller pipe 82.5 hours to fill the tank.
Find limit as x approaches three from the right of f of x. .
EXPLANATION
The expression means that we need to compute the limit as the function f(x) approaches 3 from the right.
We need to use the lines that comes from the right of 3 and gets as close as we want to x=3.
That is the line that has the open circle around y=3
Therefore, the limit is equal to 3
Hi I am having trouble with solving and finding the answers to this problem Find the perimeter of the figure. Use 3.14 for ππ and round to at least 1 decimal place.
Given:-
An reatacngle with a half sphere at one side.
To find:-
The perimeter of the given image.
Now we are going to find the perimeter of the half sphere. The formula to find half sphere is,
[tex]\pi r+d[/tex]Where r is radius and d is diameter.
The radius of the sphere is 2.5 and the diameter is 5. Substituing the values we get,
[tex]\begin{gathered} \pi r+d=3.14\times2.5+5 \\ \text{ =12.85} \\ \text{ =12.9} \end{gathered}[/tex]Now we find the perimeter of the rectangle below. we get,
[tex]5+5+5=15_{}[/tex]Now to get the total perimeter we need to add both the values. so we get,

An initial amount of money is placed in an account at an interest rate of 1% per year, compounded continuously. After six years, there is $1083.07 in the account. Find the initial amount placed in the account. Round your answer to the nearest cent.
We have to find the initial value in the account.
The interest rate is r = 1% = 0.01.
The time period is t = 6.
The final value after 6 years is FV = 1083.07.
The interest is compounded continously.
We can relate the present value PV with the other variables as:
[tex]\begin{gathered} FV=PVe^{rt} \\ PV=FVe^{-rt} \\ PV=1083.07\cdot e^{-0.01\cdot6} \\ PV=1083.07\cdot e^{-0.06} \\ PV\approx1083.07\cdot0.94176 \\ PV\approx1020.00 \end{gathered}[/tex]Answer: the initial amount was $1020.00
What is the explicit function for the data in the table ?
Let's look at the info we have for each term:
term 1 = 4
term 2 = 12
term 3 = 36
term 4 = 108
term 5 = ?
Notice that term 2 (12) is obtained from the previous term 1 (4) by multiplying it by the number 3:
12 = 4 * 3
Now, term number 3 is obtained from term 2 (the previous) also by multiplying it by 3:
36 = 12 * 3
term number 4 is obtained from multiplying the previous term (term 3) by the number 3 again:
108 = 36 * 3
Now, we can conclude that if the strategy carries on, term number 5 will be the product of the pervious term (108) times 3. That is:
term 5 = 108 * 3 = 324
Now, we need to decide on which formula better describes our function:
We find that the function is better described by the formula:
[tex]f(n)=\frac{4}{3}\cdot3^n[/tex]since we can verify:
term 1 =
[tex]\frac{4}{3}\cdot3^1=4[/tex]term 2 =
[tex]\frac{4}{3}\cdot3^2=12[/tex]term 3 =
[tex]\frac{4}{3}\cdot3^3=\frac{4}{3}\cdot27=36[/tex]term 4 =
[tex]\frac{4}{3}\cdot3^4=\frac{4}{3}\cdot81=108[/tex]So the correct answer is the second option they give you in the list.

A design was constructed by using two rectangles, ABCD and A'B'C'D'. RectangleA'B'C'D' is the result of a translation of rectangle ABCD. The table of translations isshown below. Find the coordinates of point B.
From the table, to transform points in rectangle ABCD into A'B'C'D', we have to apply the next rule: (x, y) → (x+1, y-3). That is,
A(2, 4) → (2+1, 4-3) → A'(3, 1)
C(2, -1) → (2+1, -1-3) → C'(3, -4)
D(-6, -1) → (-6+1, -1-3) → D'(-5, -4)
Then, if we want to transform a point in A'B'C'D', the rule is: (x,y) → (x-1, y+3). Applying this rule to point B', we get:
B'(-5, 1) → (-5-1, 1+3) → B(-6, 4)

Area is a unit of measurement used to describe a region's size on a flat or curved surface. While the area of a plane region or plan area refers to the area of a shape or planar lamina, surface area refers to the volume of a raised platform or the edge of a three-dimensional object.
Area is the two-dimensional equivalent of the volume of a solid as well as the length of a curve (a one-dimensional term). It can be compared to the amount of material of a certain thickness needed to create a model of the shape or the amount of paint needed to completely cover a surface in one application.

The equation representing this sentence is 72 - x/-2 = -88 because x/-2 is subtracted from 72.B.) The solution to the equation -40 + x = -8 is equal to the unknown number in the sentenceC.) The solution is 32 because -88 + 72 = -16 and -16 times -2 = 32.D.) The solution to the equation -56 + 8x = 200 is equal to the unknown number in the sentence.
ANSWER
C.) The solution is 32 because -88 + 72 = -16 and -16 times -2 = 32.
EXPLANATION
We have that 72 less than the quotient of a number and -2 is 88.
First, let us write the equation from the sentence above.
Let the number be x.
The quotient of x and -2 means x/-2
If we subtract 72 from that quotient, the answer is -88.
Therefore, the sentence is:
[tex]\frac{x}{-2}\text{ - 72 = -88}[/tex]A cannot be correct because the equation is wrong.
B cannot be correct because the equation does not relate to the sentence given.
C is correct because if we solve for x from the equation, we get 32.
That is:
x/-2 = -88 + 72
x/-2 = -16
Multiply through by -2:
x = -16 * -2
x = 32
D cannot be correct because the equation does not relate to the sentence given.
The only correct option is C.
At State College last term, 61 of the students in a Physics course earned As, 89 earned Bs, 119 got Cs, 79 were issued Ds, and 70 failed the course. If this grade distribution was graphed on a pie chart, how many degrees would be used to indicate the A region? Round your answer to the nearest whole degree.
The number of degrees that would be used to indicate region A is 53°
EXPLANATION
Number of students with As = 61
Number of students with Bs = 89
Number of students with Cs =119
Number of students with Ds = 79
Number of students with F = 70
To find the number degrees that would be used to indicate A region, we will use the formula below:
[tex]\text{ Region A in degre}e=\frac{Number\text{ of As}}{\text{Total number of student}}\times360^o[/tex]Number of As = 61
Total number of students = 61 + 89 + 119 + 79 + 70 = 418

x + 7y = -3 and y = 7x + 25. Are these parallel, perpendicular, or neither.
In order to know if those lines are parallel, perpendicular or neither we need to compare the slopes.
When two lines are parallel they have the same slope, when they are perpendicular their slopes are negative reciprocal, which means:
[tex]\begin{gathered} m_1=-\frac{1}{m_2} \\ \text{Then} \\ m_1\cdot m_2=-1 \end{gathered}[/tex]Now, we need to arrange both equations into the slope-intercept form y=mx+b
Where m is the slope and b is the y-intercept.
The second line is already in slope-intercept form:
[tex]y=7x+25[/tex]Thus, its slope is 7.
The first line in slope-intercept form is:
[tex]\begin{gathered} x+7y=-3 \\ 7y=-3-x \\ y=\frac{-3-x}{7} \\ y=\frac{-3}{7}-\frac{x}{7} \\ \text{ By reordering terms} \\ y=-\frac{x}{7}-\frac{3}{7} \end{gathered}[/tex]Then it slope is -1/7.
Their slopes are not the same, then they aren't parallel, but let's check if they are perpendicular:
[tex]\begin{gathered} m1\cdot m2=-1 \\ -\frac{1}{7}\cdot7=-1 \\ -1=-1 \end{gathered}[/tex]They are negative reciprocal, then they are perpendicular lines.
