a recipe for trail mix calls for 50 grams of almonds for every 2 cups of oats. the line represents the relationship between the amount of almonds and the amount of oats needed to make trail mix according to this recipe. the point (1, 25) is on theine. what is the equation for this line? use the format y=kx

Answers

Answer:

The equation is: y=25x

Step-by-step explanation:

Linear Modeling

When two variables have a linear dependency, the relationship between them can be written as:

y=kx+b

Where k is the slope and b is the y-intercept. When b=0, then the relationship is called proportional, and the equation is:

y=k.x

For the question, we call y=grams of almond and x=cups of oats.

It's given for x=cups of oats, the recipe for trail mix calls for y=50 grams of almonds. Substituting into the equation:

50=k.2

Solving for k:

k=50/2=25

The final equation is:

y=25x

Note the point (1,25) is on the line, as required.

What is the solution to
6(2 - x)<-4x + 2?

Answers

Answer:

Solving [tex]6(2 - x)<-4x + 2[/tex] we get [tex]\mathbf{x>5}[/tex]

Step-by-step explanation:

We need to find solution of [tex]6(2 - x)<-4x + 2[/tex]

Solving the inequality:

[tex]6(2 - x)<-4x + 2[/tex]

Multiply 6 with terms inside the bracket

[tex]12-6x<-4x+2[/tex]

Subtracting 12 on both sides

[tex]12-6x-12<-4x+2-12\\-6x<-4x-10[/tex]

Adding 4x on both sides

[tex]-6x+4x<-4x-10+4x\\-2x<-10[/tex]

Divide both sides by -2 and the inequality will be reversed i.e < will be changes to >

[tex]\frac{-2x}{-2}>\frac{-10}{-2}\\\mathbf{x>5}[/tex]

So, after solving [tex]6(2 - x)<-4x + 2[/tex] we get [tex]\mathbf{x>5}[/tex]

Jane is cooking in her recipe indicates that she should add several spices she needs to add 1/2 of a teaspoon of salt, 1 1/4 teaspoons of Orégano 3/4 of a teaspoon of basil in half as much pepper as salt. What is the total number of teaspoons of spices in the dish express the answer as a decimal

Answers

Answer: total number of teaspoons of spices in the dish =3.25 teaspoons

Step-by-step explanation:

Step 1

Listing the spices and their quantities , we have

Salt = 1/2 teaspoon

Orégano =1 1/4 teaspoon =5/4 teaspoons

Basil = 3/4 teaspoon

Pepper= in half as much pepper as salt -- This means that the quantity of pepper should be  50% more in quantity  than salt

Therefore quantity of pepper = 50% x 1/2 = 0.5 x 0.5= 0.25

0.25 +  1/2 = 0.25 + 0.5 = 0.75 = 3/4 teaspoon of pepper.

Step 2

Adding the amount of spices we have

1/2 + 5/4+ 3/4+ 3/4 = 2+ 5+3+ 3/4 = 13/4 = 3 1/4 teaspoons of spices  = 3.25 teaspoons of spices .

A baker uses chocolate with 75% cocoa for his famous cake. But his supplier delivered 100 lb of chocolate with 70% cocoa, so the baker needs to melt and mix the delivery with chocolate that has 90% cocoa. How much of the 90% chocolate should he use?

Answers

33 1/3 BTW i am from RSM too :)

33.33 lb of 90% cocoa cholcolate should be mixed.

What are percentages?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here: A baker has to mix 70% cocoa with 90% cocoa and he has 100 lb of the first chocolate.

let x lb of chocolate be mixed with 100 lb to give the 75 % chocolate variety

Thus, x×90%+100×70% / 90%+70% = 75%

         0.9x+70 /x+100=0.75

         0.9x+70=0.75x+75

           0.15x=5

                 x=33.33

Thus 33.33 lbs of 90% cocoa should be mixed to get 75% cocoa

Hence, 33.33 lb of 90% cocoa cholcolate should be mixed.

Gloria subscribes to the Webtime Internet Service. Webtime charges a $9.99 monthly service fee plus $1.50 per hour for Internet access.

Total bill = $9.99 + $1.50 × x

= 9.99 + 1.5x

Last month's bill was $ 36.99.

Hence,

9.99 + 1.5x = 36.99

Collect like terms

1.5x = 36.99 - 9.99

1.5x = 27

x = 27/1.5

x = 18 hours
