Peter mixes 4 1/2 cups of orange juice, 1 1/3 cups of ginger ale, and 6 1/3 cups of strawberry lemonade to make some punch. What is the total number of cups of punch that peter makes?

Answers

Answer:

[tex]12\frac{1}{6}[/tex] cups of punch

Step-by-step explanation:

Peter is making a punch. He mixes :

Orange juice  =  [tex]4\frac{1}{2}[/tex] cups

Ginger ale   =    [tex]1\frac{1}{3}[/tex]

Strawberry lemonade =  [tex]6\frac{1}{3}[/tex]

Now we will add all the mixes

[tex]4\frac{1}{2}[/tex] +  [tex]1\frac{1}{3}[/tex] +  [tex]6\frac{1}{3}[/tex]

Now first we convert all the mixed fractions to improper.

[tex]\frac{9}{2}+ \frac{4}{3}+ \frac{19}{3}[/tex]

Now take LCM of 2,3,3 = 6

= [tex]\frac{27+8+38}{6}[/tex]

= [tex]\frac{73}{6}[/tex] =  [tex]12\frac{1}{6}[/tex]

The total number of cups of puch that peter makes is  [tex]12\frac{1}{6}[/tex]

Peter makes a total of 12 cups and 1/6 cup (or approximately 2/3 cup) of punch by mixing 4 1/2 cups of orange juice, 1 1/3 cups of ginger ale, and 6 1/3 cups of strawberry lemonade.

To find the total number of cups of punch that Peter makes,

need to add together the quantities of orange juice, ginger ale, and strawberry lemonade.

Here are the quantities given:

Orange juice = 4 1/2 cups

Ginger ale = 1 1/3 cups

Strawberry lemonade = 6 1/3 cups

Now, add these quantities together:

4 1/2 cups + 1 1/3 cups + 6 1/3 cups

To add these mixed numbers together, it's helpful to first find a common denominator, which in this case is 6.

Convert 4 1/2 to an improper fraction: 4 1/2

= (2 × 4 + 1)/2

= 9/2

Convert 1 1/3 to an improper fraction: 1 1/3

= (3 ×1 + 1)/3

= 4/3

Keep 6 1/3 as it is since it's already in mixed fraction form.

Now, add the fractions:

(9/2) cups + (4/3) cups + (6 1/3) cups

To add the fractions, first, find a common denominator of 6:

(9/2) cups + (8/6) cups + (19/3) cups

Now, all fractions have a common denominator of 6:

(27/6) cups + (8/6) cups + (38/6) cups

Now, add the fractions:

(27/6 + 8/6 + 38/6) cups

Combine the numerators:

(27 + 8 + 38)/6 cups

Now, add the numerators:

(27 + 8 + 38) = 73

So, Peter makes a total of 73/6 cups of punch. You can also simplify this fraction:

73/6 = 12 1/6

Therefore, Peter makes 12 cups and 1/6 cup (or approximately 2/3 cup) of punch in total.

Kate is driving to visit her friend. Her gas tank starts at 55 liters. Each time the tank is down to 3 liters she refills it. She does this two times. At the last refill Kate uses allot the gas in the tank. Her car gets 8 kilometers per liter. What is the distance she gets in miles?

Answers

Each time Kate refills her gas tank, she would consume 52 liters since it was stated in the problem that there will always be 3 liters of gas before she refills the tank. It was stated that she refilled her tank for two times which means she was able to consume 104 liters (52 liters x 2). It was stated in the problem as well that Kate uses allot the gas in the tank so she consumed the remaining 3 liters in her tank. This means that the total liter she was able to consume was 107 liters (104 liters + 3 liters). To find the distance she gets in miles, you need to multiply the distance covered per liter to the total liter consumed by Kate. Therefore, she was able to get 856 miles (107 liters x 8 kilometers per liter).

a $1,600 principal earns 7% annual interest, compounded semiannually (twice per year). After 33 years, what is the balance in the account?

Answers

Given is the Principal amount, P = 1600 dollars.

Given the Annual interest is 7% i.e. r = 0.07

Given the Compounding period is semi-annually i.e. n = 2.

Given is the Time of investment, t = 33 years.

It says to find the Final Value of invested amount in the account after 33 years.

We know the formula for Future Value of Money is given as follows :-

[tex] Future \;\;Value = P*(1+\frac{r}{n})^{nt} \\\\
Future \;\;Value = 1600*(1+\frac{0.07}{2})^{(2*33)} \\\\
Future \;\;Value = 1600*(1+0.035)^{66} \\\\
Future \;\;Value = 1600*(1.035)^{66} \\\\
Future \;\;Value = 1600*(9.684185201) \\\\
Future \;\;Value = 15494.69632 \\\\
Future \;\;Value = 15,494.70 \;\;dollars [/tex]

Hence, the final balance would be 15,494.70 dollars.

Answer:

After 33 years balance in the account  = A= $15494.696

Explanation:

We will applying the compound interest formula.

[tex] A =  P(1 +\frac{r}{n})^{nt} [/tex]  

Where,

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per year

t = the number of years

Given that,

P = $1,600

r = 7%  =  [tex] \frac{7}{100}  [/tex] = 0.07

n = 2 (because of twice in a year)

t = 33 years

A= [tex] 1600(1 + \frac{0.035}{2}) ^{2*33}  [/tex] 

A =[tex]  1600 (1.035)^{66}  [/tex] 

A= $15494.696


In an ordered pair,the x-coordinate represents the number of hexagons and the y-coordinate represents the total number of sides.If the x-coordinate is 7, what is the y coordinate

Answers

The y-coordinate would be 42.

Hexagons have 6 sides.  The x-coordinate is the number of hexagons; since our x-coordinate is 7, that means 7 hexagons.  

The y-coordinate is the total number of sides.  7 hexagons * 6 sides per hexagon = 42 sides.

If the x-coordinate is 7, representing 7 hexagons, the y-coordinate, representing the total number of sides, is 42. This is because each hexagon has 6 sides, and 7 hexagons have 7 * 6 = 42 sides.

To find the y-coordinate when the x-coordinate represents the number of hexagons, and the y-coordinate represents the total number of sides, we need to use the properties of a hexagon. A hexagon has 6 sides.

Given that the x-coordinate is 7, this means there are 7 hexagons. Each hexagon has 6 sides, so to find the total number of sides (which is the y-coordinate), you multiply the number of hexagons by the number of sides each hexagon has:

x-coordinate = 7 hexagons1 hexagon = 6 sides

Thus,

y-coordinate = 7 hexagons * 6 sides per hexagon = 42 sides

Therefore, if the x-coordinate is 7, the y-coordinate is 42.

The area of a trapezoid is 18sq. ft and the sum of its bases is 6 ft. Find the area of a square whose side is equal to the height of the trapezoid.

Answers

Area = (L1 + L2)*h/2
Area = 18
L1 + L1 = 6
h = ???

18 = (L1 + L2)*h/2
18 = (6) * h/2 Multiply both sides by 2
36 = 6h Divide by 6
36/6 = h
h = 6
So the square is 6 by 6
Area square = s^2 where s is the side of the square.
Area = 6^2 = 36 

Area = (L1 + L2)*h/2

Area = 18

L1 + L1 = 6

h = ???

18 = (L1 + L2)*h/2

18 = (6) * h/2 Multiply both sides by 2

36 = 6h Divide by 6

36/6 = h

h = 6

So the square is 6 by 6

Area square = s^2 where s is the side of the square.

Area = 6^2 = 36 

so your answer will be 6^2 = 36

triangle XYZ has vertices X(6,-2.3), Y(7.5,5), and Z(8,4). when translated X' has coordinates (2.8,-1.3). Write a rule to describe this transformation. Then find the coordinates of Y' and Z'.

Answers

Final answer:

The transformation is a translation where you subtract 3.2 from the x-coordinate and add 0.7 to the y-coordinate. Using this rule, Y' is (4.3, 5.7) and Z' is (4.8, 4.7).

Explanation:

The student is asking about a translation transformation in a coordinate plane. Given the original and translated coordinates for point X, we can determine the translation rule by calculating the differences between the coordinates.

The x-coordinate has changed from 6 to 2.8, a decrease of 3.2, and the y-coordinate has changed from -2 to -1.3, an increase of 0.7. Thus, the translation rule is to subtract 3.2 from the x-coordinate and add 0.7 to the y-coordinate.

To find the translated coordinates for points Y and Z, we apply the same rule:

Y'(Y after translation) will have coordinates (7.5 - 3.2, 5 + 0.7) which simplifies to (4.3, 5.7).Z'(Z after translation) will have coordinates (8 - 3.2, 4 + 0.7) which simplifies to (4.8, 4.7).

In summary, Y' is (4.3, 5.7) and Z' is (4.8, 4.7).

To find the translation rule, we used the given coordinates of X and X' to determine a translation vector of (-3.2, 1). Using this rule, the coordinates of Y' are (4.3, 6) and Z' are (4.8, 5).

Given the vertices of triangle XYZ: X(6, -2.3), Y(7.5, 5), and Z(8, 4), and knowing that vertex X when translated has coordinates X'(2.8, -1.3), we need to determine the translation rule.

First, find the translation vector by comparing the coordinates of X and X'.The translation from X to X' is (2.8 - 6, -1.3 + 2.3) which equals (-3.2, 1).Therefore, the translation rule is: (x, y) → (x - 3.2, y + 1).Apply this rule to the coordinates of Y and Z to find Y' and Z'.For point Y(7.5, 5):
Y' = (7.5 - 3.2, 5 + 1) = (4.3, 6).For point Z(8, 4):
Z' = (8 - 3.2, 4 + 1) = (4.8, 5).

Hence, the coordinates of the translated points are Y'(4.3, 6) and Z'(4.8, 5).

here is the complete question-Triangle XYZ has vertices X(6, -2.3), Y(7.5, 5), and Z(8, 4). When translated, X` has coordinates (2.8, -1.3). Write a rule to describe this transformation. Then find the coordinates of Y' and Z'.

Answer:  " f ⁻¹ (x) = [tex] \frac{x}{4} [/tex] " . 
_______________________________________
Explanation:
_______________________________________
 "Find the inverse of " f(x) = 4x " .

1)  Let " f(x) = y = 4x " ; 

2)  Interchange the "y" and the x" :
   
    → x = 4y ; 
___________________________
3)  Isolate "y" on one side of the equation:

     x = 4y ; 

↔  4y = x ; 

Divide each side of the equation by "4" ; 
 to isolate "y"  on each side of the equation: 

   →  4y / 4 = x / 4 ; 

   →  y = x / 4 ; 
______________________________________________________

Now, change the " y"  to:  " f ⁻¹ (x) "  ;  and rewrite:
______________________________________________________
  
       " f ⁻¹ (x) = [tex] \frac{x}{4} [/tex] " .

Food Truck 2 462 471 426 654 647 732 701 684 632 698

Which conclusion can be drawn from the data?

The medians for the two taco trucks are the same
.
The two food trucks sold the most tacos on Day 3.

The range between the maximum and minimum values for taco truck 2 is greater than the range between the maximum and minimum values for taco truck 1.

On average, food truck 1 sold more tacos over the 10 days than food truck 2.

Answers

using the data for each truck lets calculate, 

median for truck 1 - 511.5
median for truck 2 - 650.5

lets consider each statement 
A.medians for both trucks are the same - wrong 
median for 1 and 2 are 511.5 and 650.5 respectively 

B. the two trucks sold most number of tacos on 3rd day 
truck 1 sold 437 on day 3 but highest number it sold was 721 on day 1
truck 2 sold 426 on day 3 but highest number was 732 on day 6
therefore this statement too is wrong 

C.
truck 1 - range between maximum(721) and minimum(425) = 296
truck 2 - maximum (732) and minimum (426) difference = 306
the range between maximum and minimum in truck 2 is 306 thats greater than range between maximum and minimum in truck 1, that's 296
therefore this statement is correct

D.
total number of tacos for each truck - 
truck 1 - 5291
truck 2 - 6107
food truck 1 sold less than truck 2 therefore this statement too is wrong 

Answer: C)  The range between the maximum and minimum values for taco truck 2 is greater than the range between the maximum and minimum values for taco truck 1.

If a parabola has its vertex at (4, -2). One of its zeros is 1. What is the other zero?

Answers

The line x=4 is halfway between the zeros, so the other one is
  2*4 -1 = 7

The other zero is x=7.

The other zero of the parabola with a vertex at (4, -2) and one zero at 1 is 7, determined by the symmetry of the parabola about its vertex.

If a parabola has its vertex at (4, -2) and one of its zeros is 1, we can find the other zero by using the concept of symmetry about the vertex. Since the axis of symmetry for a parabola with a vertical axis goes through the vertex, we know that the x-coordinate of the vertex will be exactly in the middle between the two zeros. The vertex form of a parabola's equation is typically written as y = a(x-h)² + k, where (h, k) is the vertex. In this case, the vertex is (4, -2).

Knowing that one zero is 1, we can determine that the other zero is equidistant from the vertex on the other side. This means that the distance from the vertex x-coordinate (4) to the known zero (1) is 3 units (4 - 1 = 3). So, counting 3 units in the other direction from the vertex's x-coordinate will give us the second zero: 4 + 3 = 7. Thus, the other zero of the parabola is 7.

Answers

11x + 21 < 131

11x because that is the cost of each movie ticket

21 because that is how much she want to spend on snacks

Less than 131 because she has to spend under 131
Final answer:

Natasha can treat a maximum of 10 people to the movies.

Explanation:

To determine how many people Natasha can treat to the movies, we can set up an inequality equation.

Let's say she wants to treat x number of people.

The amount she spends on tickets is $11x, and the amount she spends on popcorn and candy is $21. Since she can spend under $131, the inequality equation would be:

11x + 21 < 131.

To find the maximum number of people Natasha can treat, we need to solve this inequality:

11x + 21 < 131

11x < 110

x < 10

Natasha can treat a maximum of 10 people to the movies.
