Peter's Party Zone sells cups in packages of 666 and plates in packages of 888.
Shaniya is hosting a birthday party for her little sister and wants to have the same number of each item.
What is the least number of packages of plates Shaniya needs to buy?

It will take 12 hours for 15 men to do same job.

How to determine this?

When amount of hour ∝ 1/number of men

When H represent Hour

And M represent the number of men

k to represent the constant

H = k/M as it is inversely proportional

It takes 10 men 18 hours to repair a road

18 = k/10

k = 18 × 10

k = 180

How long will it take 15 men?

When k = 180

H = k/M

H = 180/15

H = 12 hours

Answer:

Unit rate is 2

Step-by-step explanation:

Pick two columns of the ordered pairs. Lets use (2,4) and (3,6)

The x values are 2 and 3 and the y values are 4 and 6

Now you’re going to divide y by x so

4/2 = 2

6/3 = 2

(Always choose two ordered pairs so you know that your answer is right)

Unit rate of the table is 2.

The units of concentration and rate are always going to be molars per second. We now understand that molar per second is equal to k times molar in units. An item's unit rate is its price for one of it. This is expressed as a ratio with a one as the denominator. For instance, if you covered 70 yards in 10 seconds, you covered 7 yards on average every second. Seven yards in one second and 70 yards in ten seconds are both ratios, but only one of them is a unit rate.

Given,

Choose two columns from the paired ordered columns. Using (2, 4) and (3,6)

The x and y values are 2 and 3, respectively, and the

You will now divide y by x, so

4/2 = 2

6/3 = 2

If the number of nickels in a piggy bank is 1 less than twice that of dimes and the total value of the coins is at least $4.35, then the smallest possible number of Nickels and Dimes is 43 and 22, respectively.

As per the question statement, The number of nickels in Bart's piggy bank is 1 less than twice the number of dimes, and the total value of the coins in this piggy bank is at least $4.35,

Then, we are required to determine the smallest possible number of individual coins in the bank.

To answer this question, first we will need to know the monetary values of nickels and dimes, that is,

(1 dime = 10 cents = $0.1), and (1 Nickel = 5 cents = $0.05).

Now let us assume that, there are "x" nickels and "y" dimes in that bank, Then as per the condition that, the number of nickels in Bart's piggy bank is 1 less than twice the number of dimes, we can write an equation with the above assumed two variables, which is, [x = (2y - 1)]...(i)

And as per the other condition that, the total value of the coins in this piggy bank is at least $4.35, we can write another equation, which is,

[(0.1y + 0.05x) = 4.35]

Or, [100(0.1y + 0.05x) = (100 * 4.35)]

Or, [(10y + 5x) = 435]...(ii)

Now substituting eqn (i) in eqn (ii), we get,

[{10y + 5(2y - 1)} = 435]

Or, [(10y + 10y - 5) = 435]

Or, [(10y + 10y) = (435 + 5)]

Or, (20y = 440)

Or, [y = (440/20)]

Or, (y = 22)

Therefore, [x = {(2 * 22) - 1}]

Or, [x = (44 - 1)]

Or, [x = 43]

That is, If the number of nickels in a piggy bank is 1 less than twice that of dimes and the total value of the coins is at least $4.35, then the smallest possible number of Nickels and Dimes is 43 and 22, respectively.

The probability of choosing a box and picking two quarter coins in a row is 1/108

Probability is the branch concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1. 0 indicates impossibility of the event and 1 indicates certainty.

Probability= sample space / total possible outcome

therefore probability of choosing two quarters in a row = 1/6×1/6= 1/36

The probability of choosing the first box =1/3

Therefore the probability of choosing the first box and picking two quarters In a row is 1/36×1/3= 1/108.

Since box two contain no quarter and box three has only one quarter , the probability of choosing two quarters in a row is 0.

Therefore the probability of choosing a box at random and picking two quarters in a row is 1/108.

The actual price of an item is $1371.49.

Given that, the discount percentage is 12.5% and the selling price is $1200.

A discount is the reduction of either the monetary amount or a percentage of the normal selling price of a product or service.

Let the actual price be x.

Now, x-12.5% of x =1200

⇒ x- 12.5/100 ×x=1200

⇒ x- 0.125x=1200

⇒ 0.875x=1200

⇒ x=1200/0.875

Step-by-step explanation:

The pressure that would be required to have a flow rate of 62 gal/min is f=86.25

The velocity of the stream is exactly proportional to nozzle pressure. In the given scenario, instead of a stream moving at 80 mph through the fire's super-heated gases, it moves at 60 mph.

The velocity increases as the pressure decreases in a convergent nozzle, but we know that pressure is inversely related to area.

The following formula can be used to compute the flow rate for a given nozzle. Q represents the flow rate. K = Nozzle K factor. P = Nozzle pressure differential. n = Is a constant that is determined by the type of spray pattern.

Given equation is,

f = √120p

Here p denotes the nozzle pressure in pounds per square inch

Also given that p=62 gal/min

f = √120p

The equation of the parabola from the vertex is f(x) = -3(x - 5)² + 9

The equation of the function is given as

f(x) = 3x²

Also, we have

Vertex = (5, 9)

The form of the equation is given as

f(x) = a(x - h)² + k

Where

Vertex = (h, k)

This means that

Vertex = (h, k) = (5, 9)

Substitute (h, k) = (5, 9) in the equation f(x) = a(x - h)² + k

So, we have

f(x) = a(x - 5)² + 9

This also means that

f(x) = -3(x - 5)² + 9

The -3 is gotten from f(x) = -3x²

The value of (fоg)(3) = 134.

What is composition of functions?

A function is composed in mathematics when two functions, f and g, are used to create a new function, h, such that h(x) = g(f(x)). The function of g is being applied to the function of x, in this case. Therefore, a function is essentially applied to the output of another function.

Consider, the given functions

f(x) = 3x - 1, g(x) = 4x^2 + 9

First to find f(g(x)).

Let,

f(g(x)) = 3(4x^2 + 9) - 1

         = 12x^2 + 27 - 1

f(g(x)) = 12x^2 + 26

Now, to find f(g(3)).

Plug x = 3 in the above equation,

f(g(3)) = 12(3)^2 + 26

f(g(3)) = 134

We have to check the ratios 1/3 and 2/5 form a proportion or not.

As we know that proportion is a ratio in which both ratios are equal to each other.

So to check whether the given statement is proportion or not we put both equation equal to each other.

So the ratios are 1/3 and 2/5.

Now checking the proportion.

1/3=2/5

Multiply by 15 on both side.
