The number of quarts of each constituent she needs to produce 16 quarts of punch is; 12 quarts of fruit juice and 4 quarts of citrus soda.

It follows from the task content that the quantity of each constituent that is required to make 16 quarts of punch are to be determined.

Since it follows that 3 quarts of fruit juice are required to mix with every quart of citrus soda, it follows that the amount of punch made in this scenario is; 4 quarts of punch.

Hence, since there are 4 partitions of 4 quarts punch is 16 quarts punch, the amount of.each constituent needed by proportion are as follows;

Work Shown:

A = he eats pizza

B = he drinks cola

P(A) = 0.40

P(B) = 0.60

P(A and B) = 0.30

Then apply the conditional probability formula.

P(A given B) = P(A and B)/P(B)

P(A given B) = 0.30/0.60

P(A given B) = 0.5 exactly

P(A given B) = 50%

If we know for certain he drinks cola, then there's a 50% chance of him eating pizza.

From the problem, we have 3.25% to convert into fraction.

Note that percentage a% can be written as a/100

So 3.25% will be :

From here, we can multiply the numerator and the denominator by 100 to make 3.25 a whole number.

Next step is to simplify the fraction by getting the factors of the numerator and the denominator.

325 = 25 x 13

10000 = 25 x 400

Rewriting it again :

Cancel the common factor (25)

The answer is 13/400

The most appropriate choice for equation of line in slope intercept form will be given by-

y = 2x - 8 is the required equation of line

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan \theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line

Here,

The given equation of line is y= 2x +3

Slope of this line = 2

Slope of the line parallel to this line = 2

The line passes through (-2, -12)

Equation of the required line = y - (-12) = 2(x - (-2))

                                                = y + 12 = 2x + 4

                                                = y = 2x + 4 - 12

                                                = y = 2x - 8

First, we need to calculate the total earned during the three days, so we need to sum 20.56, 32.90, and 20.78 as:

So, the total earned is 74.24, then half of 74.24 is calculated as:

If he spends the half, he has left the half. Therefore, he has left 37.12

Answer: 37.12

We can solve these values using the next triangle:

First, we need to label the sides using the angle of 30 degrees.

- The largest side is always the hypotenuse, h = 1.

- The opposite side is opposite to the angle, opp = 1/2.

- The adjacent side is between the angle of 30 degrees and the right angle,

adj = √3/2.

Now, we can solve the trigonometric expressions:

For sin:

sin θ = opposite side / hypotenuse

sin 30 = (1/2) / 1

sin 30 = 1/2

For cos:

cos θ = adjacent side / hypotenuse

cos 30 = (√3/2)/1

cos 30 =√3/2

For tan:

tan θ = opposite side / adjacent side

tan 30 =(1/2) / (√3/2)

Simplify the fractions:

tan 30 = 1/√3

Answer:

The 3 consecutive even numbers are 60, 62 and 64 and the value of the greatest is 64.

Explanation:

If the numbers are consecutive even numbers, it means that the next number will be 2 more than the previous one.

Let the 1st number be x, then other 2 consective numbers will be x + 2 and x + 4.

We're told that the sum of the 3 consecutive even numbers is equal to 186, our equation can then be written as shown below;

Let's go ahead and collect like terms and solve for x;

So our 1st number is 60.

Let's go ahead and find the other 2 numbers;

1st number: x + 2 = 60 + 2 = 62

2nd number: x + 4 = 60 + 4 = 64

So the 3 consecutive even numbers are 60, 62 and 64 and the value of the greatest is 64.

`Answer:

h(x) = -x^2/2 - 4x + 32

Explanation:

The standard form of a quadratic equation is expresssed as

ax^2 + bx+c

Writing the given equation h(x)= -1/2 (x+4)^2 +10 in stabdard form will give;

h(x)= -1/2 (x+4)^2 +10

h(x)= -1/2 (x^2+8x+16)+40

h(x)= -x^2/2 - 4x - 8 + 40

h(x) = -x^2/2 - 4x + 32

Hence the equation in standard form is expressed as h(x) = -x^2/2 - 4x + 32

The weight of the granite pyramid in tons is 1350 tons.

A pyramid is a three-dimensional shape.

The granite pyramid is 50 feet high and has a square base of 30 feet on a side.

Granit weighs 180 pounds per cubic foot.

Therefore, the weight in tons of the pyramid can be calculated as follows;

Hence,

volume of the granite pyramid = 1 / 3 b² h

Therefore,

volume of the granite pyramid = 1 / 3 × 30² × 50

volume of the granite pyramid = 45000 / 3

volume of the granite pyramid = 15000 ft³

Hence,

1 ft³ = 180 pounds

15000 ft³ = ?

weight = 2700000 pounds

1 pounds = 0.0005 tons

2700000 pounds = ?

Therefore,

weight of the pyramid granite in tons = 1350 tons

Step 1:

Cost of large cup = $5

Step 2:

Number of large David orders = 10 cups

A good plan to find the amount Jon spent is to find the number of large cups Jon orders from the number of large cups David orders.

Jon order 4 fewer large cups

Therefore,

Jon order = 6 cups

Step 3:

A good plan to find the amount Jon spent is to find the number of large cups Jon orders from the number of large cups David orders.

The amount Jon spent on coffee = 6 x $5 = $30

To find the factors of a number, we can look for factors to divide it by subsequently.

It is easier to start with lower factors.

Let's start by "2".

Since "54" is even, it is divisable by "2":

So "2" is one of the factors.

Now, we have got 27. It is not even anymore, but it is divisable by "3":

So "3" is another factor.

Now we have got "9" and it is also divisable by "3":

So there is another "3" factor.

And since we have got now another "3", we know it is divisable by "3":

Now we have got to "1", so we found all the prime factors:

Now,, we need to combine them to find all possible combinations.

We will start from low to high.

"1" is always a factor.

There is "2" there, so it is also a factor.

Then we have "3" as another factor.

There is no need to combine "1" with another factor, so we will start b combining 2 and 3:

So, "6" is another factor.

We can combine 3 with 3:

"9" is another factor.

Now we start combining three of them:

So, "18" and "27" are factors.

And now we combine 4 of them, but this is get us back to "54" which is the last factor.

So, the factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54.

Answer:

Step-by-step explanation:

1 × 54 = 54, (1, 54) is a pair factor of 54.

2 × 27 = 54, (2, 27) is a pair factor of 54

3 × 18 = 54, (3, 18) is a pair factor of 54

6 × 9 = 54, (6, 9) is a pair factor of 54

Therefore, the positive pair factors are (1, 54), (2, 27),(3, 18) and (6, 9).

12x - 9y +12 =0

To find the slope and y intercept, we want to put the equation in slope intercept form

y = mx+b where m is the slope and b is the y intercept

Solve the equation for y

Add 9y to each side

12x - 9y+9y +12 =0+9y

12x+12 = 9y

Divide each side by 9

12x/9 +12/9 = 9y/9

4/3 x + 4/3 = y

Rewriting

y = 4/3x + 4/3

The slope is 4/3 and the y intercept is 4/3
