grandma famous punch uses a ratio of 5 cups of cranberry juice and 2 cups of sprite. if she needs a total of 56 cups of famous punch how amy cups of cranberry and how many cups of sprite to make 56 cups of punch

Answers

You will need 280 cups of cranberry juice and 56 cups of Sprite to make 56 cups of the famous punch.

What is the ratio definition?

A ratio is a mathematical comparison of two or more values or quantities. It is usually written as a fraction, with the first value or quantity being the numerator and the second value or quantity being the denominator.

To make 56 cups of famous punch using the ratio of 5 cups of cranberry juice to 2 cups of Sprite, you can use the following method:

Write the ratio of cranberry juice to Sprite as a fraction: 5 cups cranberry juice / 2 cups sprite

Multiply the fraction by the desired number of cups of punch: (5 cups cranberry juice / 2 cups sprite) x 56 cups punch

Simplify the equation by cross-multiplying: 5 cups cranberry juice x 56 cups punch = 2 cups sprite x 56 cups punch

Solve for the number of cups of cranberry juice: 5 cups cranberry juice x 56 cups punch = 280 cups of cranberry juice

To find the amount of Sprite use the ratio 5:2, meaning you have to use 2 cups of sprite for every 5 cups of cranberry juice. So use 280/5*2 = 56 cups of sprite

Hence, you will need 280 cups of cranberry juice and 56 cups of Sprite to make 56 cups of the famous punch.

The chef needed a) 3¾ cups of lemon juice and b) 20 pints olive oil for the larger batch.

What is mixed fraction?

A mixed fraction is one that has both its quotient and remainder represented. A mixed fraction like 2 1/3 is one where the remainder is 1 and the quotient is 2. Therefore, a mixed fraction is made up of both a whole number and a correct fraction.

The recipe was for 4 person, but now here are 40

The scale multiple is = 40/4

                                   = 10

a) As 1 cup = 16 tablespoon

The number of tablespoon of lemon required for 40 men = 6 × 10

                                                                                                 = 60

Converting to cup = 60/16

                              = 3¾ cups

b) As 1 cup = 0.5 pints

The number of cups of olive oil required for 40 men = 1 × 10

                                                                                        = 10

Converting to pints = 10/0.5

Recall the equation for a circle with centre (h,k) and radius r. At what point in the first quadrant does the line with equation y=1.5x+5 intersect the circle with radius 5 and centre (0,5)?

Answers

The equation for the circle is (x-h)^2 + (y-k)^2 = r^2. Substituting the values, we get (x-0)^2 + (y-5)^2 = 25.

Substituting y=1.5x+5 into the equation, we get (x-0)^2 + (1.5x+5-5)^2 = 25

Simplifying, we get 1.5x^2 +15x+25=25

Solving, we get x=1.

Therefore, the point of intersection is (1,1.5).

The line y=1.5x+5 intersects the circle with radius 5 and centre (0,5) at the point (1,1.5) in the first quadrant.

The equation for a circle with centre (0,5) and radius 5 is (x-0)^2 + (y-5)^2 = 25. When this equation is combined with the line equation y=1.5x+5, it can be solved to find that the line intersects the circle at the point (1,1.5), which is located in the first quadrant.

(Round your answers to two decimal places.)
From Pine Knob:

Answers

The distance of the fire from each tower is:

i. From Pine Knob: 41 kilometers

ii. From Colt Station: 15 kilometers

What is Bearing?

Bearing as a topic in mathematics can be used to determine the exact position or location of an object considering its angle of position and distance to a reference point.

Considering the given question; let the distance of the fire (F) from Pine knob (PK) be represented by x, and that from Colt Station (CS) be represented by y.

Angle at PK = 80 - 65

                    = 15^o

Angle at CS = 65 + 70

                    = 135^o

Angle at F can be determined as;

15 + 135 + F = 180   (sum of angle in a triangle)

150 + F = 180

F = 30^o

So that applying the Sine rule to determine the distances of the fire from PK and CS, we have;

a/Sin A = b/Sin B = c/Sin C

29/Sin 30 = y/Sin 15 = x/ Sin 135

29/Sin 30 = y/Sin 15

y = (29*Sin 15)/ Sin 30

  = 7.5052/ 0.5

  = 15.0104

y = 15 kilometers

29/Sin 30 = x/Sin 135

x = (29*Sin 135)/ Sin 30

  = 20.5059/ 0.5

  = 41.0118

x = 41 kilometers

Therefore, the distance from Pine Knob to the fire is 41 kilometers. While the distance from Colt Station to the fire is 15 kilometers.

75% of the Pottery Club members paid their $5.00 dues. If there are 48 members, how many members paid?

Answers

Answer:

36 members paid the total money that would be made would be $180

Step-by-step explanation:

48*75%=36

36*5=180

If 75% of the Pottery Club members paid their dues, then 75/100 = 3/4 of the members paid.
If there are 48 members in the Pottery Club, then to find out how many members paid, we can multiply the total number of members by the proportion that paid, which is:
48 x 3/4 = 36 members paid.
So 36 members paid the $5.00 dues.

Answers

The solution to the differential equation with the initial condition given is y(x)= (x² + 1)⁴.

Step 1: The given differential equation is dy/dx = 2xy/(x² + 1). Rearranging the equation, we get dy = 2xy dx/(x² + 1).

Step 2: Integrating both sides, we get ∫dy = ∫2xy dx/(x² + 1). On the left side, we have ∫dy = y + C, where C is the constant of integration. On the right side, we have ∫2xy dx/(x² + 1) = x² y + C.

Step 3: Substituting the initial condition y(3) = 6 in the solution, we get 6 = 3² y + C. Solving for C, we get C = 6 - 9y.

Step 4: Substituting C = 6 - 9y in the solution, we get y(x) = (x² + 1)⁴

The solution to the differential equation with the initial condition given is y(x)= (x² + 1)⁴.

Step-by-step explanation:

Queen Laetitia is sorting her gem collection. She starts by placing some of her
diamonds into two boxes. In every box after the first two, the Queen puts as many
diamonds as in the previous two boxes combined. If there are 30 diamonds in the
fourth box, and 128 diamonds in the seventh box, how many diamonds did
Queen Laetitia place in the tenth box?

Answers

Answer:

Step-by-step explanation:
Let's represent the missing number with "---" -- so we have so far:

--- --- --- 30 --- --- 128 --- ---  ?
Now, let's say 5th position number is x and 6th position number is y
So, we have 30 + x = y and x+ y = 128
Combining these 2 equation, we get: x + 30 + x = 128 or x = 49, so y = 79

thus from 4th position, the series can be written as
30, 49, 79, 128, 207, 335, 542....
Thus, at 10th position we will have 542 !!!

There are some lefties among the 5 people is, 50.16%

What is probability?Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability. A probability is a number that expresses the possibility or likelihood that a specific event will take place. In addition to being expressed as percentages ranging from 0% to 100%, probabilities can also be expressed as proportions between 0 and 1.

The first lefty is the fifth person chosen is

[tex](.87)^4(.13)=.07447=7.45 \%[/tex]

There are some lefties among the 5 people is,

[tex]$$1-(.87)^5=.50157=50.16 \%$$[/tex]

The first lefty is the second or third person.

[tex]$(.87)(.13)+(.87)^2(.13)=.211497=21.15 \%_0$[/tex]

There are exactly 3 lefties in the group.

[tex]$(5, .13,3)=.0166=1.66 \%$[/tex]

There are at least 3 lefties in the group,

[tex]1 \text { - binomadf }(5, .13,2)=.0179=1.79 \%[/tex]

There are no more than 3 lefties in the group

A function built from pieces of different functions over different intervals.

How does one locate the piecewise specified formula?

Finding a Piecewise Function’s Equation: Find the equation for both y=mx+b lines. If there is an O, the equation is > or; if there is a •, the equation is or. In the equation, the line represents X.

A piecewise function is one that is constructed from parts of distinct functions at different intervals. For example, we may write a piecewise function f(x) that returns -9 when -9 x -5, 6 when -5 x -1, and -7 when -1.

Answers

The expansion of 1/4(x - 12) is x/4 - 3

What is expansion of expression?

In order to expand and simplify an expression, we need to multiply out the parentheses and then simplify the resulting expression by collecting the like terms. Expanding brackets (or multiplying out) is the process by which we remove parentheses. It is the reverse process of factorisation.

For example 4(3-y) can be expanded by multiplying the factor 4 by 3 and y = 12- 4y

Similarly the expression 1/4(x - 12) can be expanded by firstly multiply the factor ¼ by x and 12

therefore 1/4(x - 12) = 1/4×x -12×1/4

= x/4 - 3

Therefore the expansion of 1/4(x - 12) is x/4 -3
