The p (the total number of players at the baseball game) = 16 players:

The equation to determine p: 3/4 = 12/p

The total number of players at the baseball game = p.

Given that, 3/4 of the players chose a bottle of water = 12p.

To write an equation to determine p, we can set up the following proportion:

3/4 = 12/p

This equation above represents the ratio of players who chose a bottle of water (3/4) to the total number of players, which is =  12 players.

To solve for p, we cross-multiply and then solve for P:

3p= 4 * 12

3p = 48

p = 48 / 3

p = 16

Answer:

6C + $50 is the correct answer

Since, the father is 30 years older than his son. Then, the son's age is 10 years old. Therefore, the father's age is x+30 = 40 years old.

Let's denote the son's current age as S and the father's current age as F. From the information given, we know:

1. F = S + 30 (the father is 30 years older than his son)
2. F + 5 = 3 * (S + 5) (the father will be three times as old as his son in 5 years)

Now, we need to solve for F:

Step 1: Substitute the first equation with the second equation:
(S + 30) + 5 = 3 * (S + 5)

Step 2: Simplify the equation:
S + 35 = 3S + 15

Step 3: Move all terms with S to one side and constants to the other side:
35 - 15 = 3S - S
20 = 2S

Step 4: Divide by 2 to isolate S:
S = 10

Now that we know the son's age, we can find the father's age using the first equation:

F = S + 30
F = 10 + 30
F = 40

The father's present age is 40 years old.

For a catering company, which used the linear function for calculating the total cost of parties, the cost to cater a dinner party with 90 guests is equals to the $42750.

We have a table form data of total cost of parties for a catering company. There is use of linear function to determine total cost of parties. Table look like as below,

Cost for dinner parties | number of guests

(each guest)

$315 30

$555 60

We have to determine the cost to cater a dinner party with 90 guests. For this we use simple multiplication arithmetic method. As we see in table, cost of cater a dinner party with 30 guests = $315 for each , that is cost for one guest = $315

so, cost of cater a dinner party with 30 guests = 30 × $315 = $ 9450

Similarly, when number of guests is 60 in count, cost of cater a dinner party = $555 for each one

So, total cost of cater a dinner party with 60 guests = 60× $555 = $ 33300

Now, we have total guest = 90

The cost to cater a dinner party with 90 guests

= cost to cater a dinner party with 30 guests + cost to cater a dinner party with 60 guests = $9450+ $33300

= $42750

Hence, required value is $42750.

Answer:

We can use the formula for the lateral surface area of a cone to find the slant height:

Lateral surface area = πrℓ, where r is the radius and ℓ is the slant height.

Since the paper cup is hollow, the lateral surface area is equal to the outer surface area of the cup, which is given as 17.9 square inches. The radius of the cup is half the diameter, which we do not know, so let's call it d:

r = d/2

We also know that the lateral surface area is given by:

17.9 = πrℓ

Substituting r = d/2, we get:

17.9 = π(d/2)ℓ

Simplifying, we get:

ℓ = (2*17.9)/(πd)

Using an approximation of π = 3.14, we can calculate:

ℓ ≈ (2*17.9)/(3.14d) = 11.40/d

Since we do not have any information about the diameter of the paper cup, we cannot calculate the exact slant height.

The domain of the height function is:

t ∈ [0, 4.5]

We know that the height of the function is modeled by the quadratic equation:

h = -16t² + 64t + 36

The domain is the set of the possible values of t.

The initial value of the domain is at t = 0s, to find the maximum value, we need to find the value of t such that the height is zero (when the rocket hits the ground)

Then we need to solve:

-16t² + 64t + 36 = 0

Using the quadratic formula we will get:

[tex]t = \frac{-64 \pm \sqrt{64^2 - 4*(-16)*36} }{2*-16} \\\\t = \frac{-64 \pm80}{-32}[/tex]

Answer:

Step-by-step explanation:

The slope of a line passing through two points (x1,y1) and (x2,y2) can be calculated using the formula:

slope = (y2 - y1) / (x2 - x1)

Using the given points (8,1) and (2,-9), we can substitute the values into the formula:

slope = (-9 - 1) / (2 - 8)

slope = -10 / -6

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 2:

slope = (-10 / 2) / (-6 / 2)

slope = -5 / 3

Therefore, the slope of the line passing through the points (8,1) and (2,-9) is -5/3.

The linear approximation of f(x)= sqrt(4-x) at a=0 can be used to approximate sqrt(3.9) and sqrt(3.99) as 0.0500 and 0.0050, respectively.

The linear approximation of the function f(x)= sqrt(4-x) at a=0 is given by:

L(x) = f(a) + f'(a)(x-a)
    = sqrt(4-0) + (-1/2)(x-0)
    = 2 - 0.5x

To approximate the numbers sqrt(3.9) and sqrt(3.99) using L(x), we need to plug in the values of x and round the answer to four decimal places.

For sqrt(3.9), we have:

L(3.9) = 2 - 0.5(3.9)
      = 0.05

Rounding to four decimal places, we get:

L(3.9) ≈ 0.0500

For sqrt(3.99), we have:

L(3.99) = 2 - 0.5(3.99)
       = 0.005

Rounding to four decimal places, we get:

L(3.99) ≈ 0.0050

Therefore, the linear approximation of f(x)= sqrt(4-x) at a=0 can be used to approximate sqrt(3.9) and sqrt(3.99) as 0.0500 and 0.0050, respectively.

To find the linear approximation L(x) of the function f(x) = sqrt(4-x) at a=0, we need to calculate the value of the function and its derivative at a=0:

f(a) = f(0) = sqrt(4-0) = sqrt(4) = 2

Now, we find the derivative of f(x) with respect to x:
f'(x) = d/dx(sqrt(4-x)) = -1/(2*sqrt(4-x))

Next, evaluate f'(x) at a=0:
f'(0) = -1/(2*sqrt(4-0)) = -1/(2*2) = -1/4

The linear approximation L(x) is given by:
L(x) = f(a) + f'(a)(x-a)
L(x) = 2 - (1/4)(x-0) = 2 - (1/4)x

Now, we use L(x) to approximate sqrt(3.9) and sqrt(3.99):
L(0.1) = 2 - (1/4)(0.1) = 1.9750
L(0.01) = 2 - (1/4)(0.01) = 1.9975

So, the linear approximations of sqrt(3.9) and sqrt(3.99) are 1.9750 and 1.9975, respectively.

The smallest possible total number of tokens in the jar is 27, with 6 red tokens, 3 white tokens, and 18 blue tokens.

Let's assume that the jar has "r" red tokens, "w" white tokens, and "b" blue tokens. Since the probability of selecting a red token and then a white token is the same as selecting a blue token, we can write the following equation

(r/3) × (w/3) = (b/3) × ((r + w)/3)

Simplifying this equation, we get

rw = b(r + w)

Now, we need to find the smallest possible total number of tokens in the jar. Since r, w, and b are all multiples of 3, we can write

r = 3x

w = 3y

b = 3z

Substituting these values in the equation rw = b(r + w), we get

9xy = 9z(x + y)

Simplifying this equation, we get

xy = z(x + y)

Since x, y, and z are all integers, we can say that z divides xy. Therefore, we can write

z = kd

xy = k(d x + d y)

where k and d are integers.

Now, we need to find the smallest possible value of (r + w + b) = 9(x + y + z) that satisfies the above conditions. Since z is a multiple of 3, we can start with k = 3. Also, we want to minimize (x + y + z), so we can start with d = 2. Substituting these values, we get

z = 3 × 2 = 6

xy = 3(2x + 2y) = 6(x + y)

The smallest possible values of x and y that satisfy this equation are x = 2 and y = 1. Substituting these values, we get

r = 3x = 6

w = 3y = 3

b = 3z = 18

Therefore, the smallest possible total number of tokens in the jar is

r + w + b = 6 + 3 + 18 = 27

Answer:

To factor f(x) = x^2 + 10x + 16, we need to find two numbers whose sum is 10 and whose product is 16.

The two numbers are 2 and 8, since 2 + 8 = 10 and 2 × 8 = 16.

Therefore, we can write:

f(x) = x^2 + 10x + 16

= x^2 + 2x + 8x + 16

= (x^2 + 2x) + (8x + 16)

= x(x + 2) + 8(x + 2)
