The simplest form of w : x : y : z will be;

⇒ w : x : y : z = 20 : 30 : 9 : 1

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that;

Olivia and Jessica have in total half as many sweets as Fran and Gary have in total.

Now,

Let Fran got w sweets.

Gary got x sweets.

Olivia got y sweets.

Jessica got z sweets.

So, We get;

⇒ (y + z) = 1/2 (x + w)    ..(i)

Here, w = 2a and x = 3a

And, y = 9b and z = b

Substitute in equation (i), we get;

⇒ (y + z) = 1/2 (x + w)    

⇒ (9b + b) = 1/2 (2a + 3a)  

⇒ 10b = 1/2 (5a)

⇒ 20b = 5a  

⇒ 10b = a

So, w = 20b and x = 30b

Or, w : x = 20b : 30b

So, w : x: y: z = 20b : 30b : 9b : b

                     = 20 : 30 : 9 : 1

Thus, The simplest form of w : x : y : z will be;

⇒ w : x : y : z = 20 : 30 : 9 : 1

Answer:

5.75x = f(x)

22.99 + 2.09x = g(x)

Step-by-step explanation:

Divide them into two parts:

Normal drinks and commemorative drinks

- With normal, only $5.75 is related (Only one drink at a time so 5.75x)

- With commemorative, $22.99 and $2.09 are related (A one time fee of $22.99, then a refill of $2.09; so 22.99 + 2.09x)

Answer:

Many solutions

Step-by-step explanation:

If it is manipulated, you simply get:

2x + 2x + 2 = 4x + 2

0 = 0

So, there are infinitely many solutions, as anything you plug in for x will be canceled as there are 4 x's on both sides.

Stephen Talked for 138 minutes.

Step-by-step explanation:

(0.10)m + 10.00 = 23.80         Given

Answer: Sunny Horizon Cellular’s phone plan has a monthly fee of $10.00 and charges $0.10 for every minute used. Stephan’s bill for the month was $23.80. If the equation that models this situation is (0.10)m + 10.00 = 23.80, use inverse operations and properties of equality to find the number of minutes Stephan talked during the month.

Answer:

only students who have recess at 12 p.m. or later may go out

Step-by-step explanation:

Let the time after midnight be represented by t, and the temperature be y. Since the temperature increases by 1.2 degrees Fahrenheit each hour, the time taken to reach 32 degrees Fahrenheit can be gotten from:

y = 1.2t + 18

put y = 32

32 = 1.2t + 18

1.2t = 14

t = 14/1.2 = 11.67 hours

Since the recess starts at half hour or hour, hence the recess would start at t = 12 hours, i.e. at 12 p.m.

Hence only students who have recess at 12 p.m. or later may go out

Answer:

i know im late but here only students who have recess at 12 p.m. or later may go out

0 slope as it is a horizontal line when you graph it

Step-by-step explanation:

Answer:

A.

Step-by-step explanation:

the slope of a line is behind the x in a linear equation.

f(x)=5x-2 is a linear equation

So, the slope of f(x) is 5.

Since A is the only choice with this answer, A is correct.

Answer:

Step-by-step explanation:

Answer:

19

Step-by-step explanation:

The first thing is recognize that it is a rectangle and two triangles with given bases and heights.

So the first step is finding the area of both triangles, which you can do with the formula for the area of a triangle:

A = (BH)/2

Because the height is two, the area is going to be equal to the base.

The sum of the two triangles is 7.66.

Next you want to find the area of the rectangle, you can do so using the formula:

A = BH

A = 6(2)

The area of the rectangle is 13.

Find the sum of the areas of the three shapes.

3.30 + 4.36 + 12 = 19.66

Answer:

20 cakes were sold

Step-by-step explanation:

I assume the question is how many cakes did they sell

set up equation

$5 per cake equals $100

5x = 100

divide both sides by 5

5x ÷ 5 = 100 ÷ 5

1x = 20

x = 20

Answer:

4.35 / 100 = 0.0435

Step-by-step explanation:

We find it useful to convert 4.35% to decimal, because if you need to find 4.35% of any number, you can simply multiply that number with 0.0435.

the objective function is

maximize

36.50x+109.50y=P

constraints

2X+6Y<=600-----1

X+Y=200-----------2

solve 1 and 2 simultanouesly

mutiply  eqn 2 by 2 we have

2x+6y=600-------1

2x+2y=200--------3

subtract the eqns 3 from 1

4y=400

y=100

put y=100 in eqn 2 we have

x+100=200

x=200-100

x=100

36.50x+109.50y=P

36.50(100)+109.50(100)=P

 3650+10950=P

P=$14600

Assignment: Type one to two paragraphs that describe your models and relate them to the law of conservation of mass. Your document should:

Identify the names of the reactants and products in the reaction.

Identify the number of molecules that make up the reactants and products.

Identify the type and number of atoms in each molecule of the reactants and products.

Explain what happens during the chemical reaction.

Explain how mass is conserved during the chemical reaction

The name of the reactant in this reaction is called Calcium Carbonate (CaCO3) and the products in this reaction are Calcium Oxide (CaO) and Carbon Dioxide (CO2). There are 5 atoms total in calcium carbonate: one calcium atom, one carbon atom, and 3 oxygen atoms. In calcium oxide there are 2 atoms total: one calcium atom and one oxygen atom. In carbon dioxide there are 3 atoms total: one carbon and two oxygen atoms. So in the reaction the mass of the products stayed the same because according to the law of conservation, “in a closed or isolated system, matter cannot be created or destroyed. It can change forms but is conserved.” This can be seen in the reaction because no matter was made or destroyed, it was all just rearranged. To further explain, the law of mass conservation in chemistry states that, “in a chemical reaction, the mass of the products equals the mass of the reactants,” which further proves that no matter was created or destroyed, just rearranged. In conclusion, in the reaction the products had the same number of atoms as the reactant because no matter was destroyed or created, simply rearranged to create new products!
