Dozen Oatmeal = $4 and Dozen Chocolate = $9

Step-by-step explanation:

Dozen Oatmeal:

10 dozen oatmeal and 1 dozen chocolate =$49

9 dozen oatmeal and 1 dozen chocolate = $45

The second customer bought 1 less dozen and paid $4 fewer dollars, therefore 1 dozen oatmeal must equal $4

Dozen Chocolate: let C = 1 dozen chocolate

10 dozen oatmeal + 1 dozen chocolate = $49

(10 x $4) + C = $49

$40 + C = $49

-40             -40

C = $9

1 dozen chocolate cookies = $9

The number of yellow jellybeans will be 9.

It is given that total number of jellybeans in a bag are 27 which are in ratio 2 green to 4 pink to 3 yellow or 2:4:3

We have to calculate the number of yellow jellybeans in the bag.

What will be the ratio of girls , if there are 80 students in a college , out of which 60 are male ?

The ratio of girls will be [tex]\frac{80-60}{80}[/tex] = [tex]\frac{20}{80}[/tex] = [tex]\frac{1}{4}[/tex] or 1:4.

As per the question ,

The ratio of jellybeans in a bag is 2 green to 4 pink to 3 yellow or 2:4:3.

Total number of jellybeans in the bag is 27.

So ,

Let's assume the common factor as x.

No. of green jelly = 2x

No. of pink jelly = 4x

No. of yellow jelly = 3x

We can write this as ;

2x + 4x + 3x = 27

9x = 27

x = 27 ÷ 9

x = 3

So , the number of yellow jellybeans will be ;

= 3 × x

= 3 × 3

= 9

Thus , the number of yellow jellybeans will be 9.

[tex]\huge\boxed{x=0,\ y=3\to(0;\ 3)}[/tex]

Step-by-step explanation:

[tex]\left\{\begin{array}{ccc}x+3y=9&\text{subtract }3y\ \text{from both sides}\\4x-2y=-6\end{array}\right\\\\\left\{\begin{array}{ccc}x=9-3y&(1)\\4x-2y=-6&(2)\end{array}\right[/tex]

Substitute (1) to (2):

[tex]4(9-3y)-2y=-6\qquad|\text{use the distributive property}\\\\(4)(9)+(4)(-3y)-2y=-6\\\\36-12y-2y=-6\qquad|\text{subtract 36 from both sides}\\\\-14y=-42\qquad|\text{divide both sides by (-14)}\\\\y=3[/tex]

Put it to (1):

[tex]Ratio = 2 : 15[/tex]

Step-by-step explanation:

Given

[tex]Ratio = 8 : 60[/tex]

Required

Write in the simplest form

[tex]Ratio = 8 : 60[/tex]

Divide by 2

[tex]Ratio = 8/2 : 60/2[/tex]

[tex]Ratio = 4 : 30[/tex]

Divide by 2

[tex]Ratio = 4/2 : 30/2[/tex]

[tex]Ratio = 2 : 15[/tex]

Answer:

In distributions in which many scores differ greatly from the distribution’s mean, the bigger the:

D) standard deviation.

Step-by-step explanation:

The more spread out or variable a data distribution is, the greater its standard deviation.  A standard deviation is the square root of the variance. A mean is an average of all set of available data.  It is obtained by dividing the value of data by the number of the data set.  The standard deviation is the statistics that basically measure the distance from the mean, and is calculated as the square root of variance determined by each data point relative to the mean.

The number of times the message repeated is 86400.

It is required to find how many times did the message appear on the sign.

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

An electronic advertising sign repeats a message every 9 seconds, day and night, for a week.

We have to find the number of seconds in a week:

T=3600*24*7

=604800 s

Since each message takes 7 seconds, the number of messages is

=604800/7

=86400.

Therefore , the number of times the message repeated is 86400.

Answer:

16sqrt5

Step-by-step explanation:

Notice that the next term is the previous term multiplied by sqrt2.

So we can take sqrt5 and multiply it by sqrt2, 8 times to get the ninth term.

sqrt2 ^8 = 16.

So 16sqrt5

Answer:

The actual length of the route is 8400.

Step-by-step explanation:

Given that:

Ratio of scale drawing = 1 : 300

It means that 1 cm on the scale drawing is equal to 300 in actual length.

We have to find the actual distance for 28 cm on the scale drawing.

Let,

x be the actual length of route.

This shows a proportional relationship.

1 : 300 :: 28 : x

Product of extreme = Product of mean

x = 300*28

x = 8400

Hence,

The actual length of the route is 8400.

Answer: we need 3 cups of white paint and 5 of yellow paint if we want to make 1 batch.

Step-by-step explanation:

I suppose that each one of these squares represents one cup of the given color.

(the white squares represent the cups of white paint and the yellow squares represent the number of cups of yellow paint)

We know that for 3 batches of the paint, we need:

9 cups of white paint.

15 cups of yellow paint.

Now, if we only want to do one batch, then we should use one-third of these numbers of cups. (Because with that we make 3 batches, and one-third of 3 batches is one batch)

Originally, we use 9 cups of white paint, then for one batch we need one-third of 9 cups, this is:

9/3 = 3

Then we should use 3 cups of white paint.

And for the yellow paint, we originally use 15 cups, one-third of 15 is:

15/3 = 5

Then we should use 5 cups of yellow paint.

We can conclude that we need 3 cups of white paint and 5 cups of yellow paint if we want to make 1 batch.

This would be represented with 3 white squares and 5 yellow squares.

Answer:

{12, 4, -6}

Step-by-step explanation:

f(x)=4-2x

x = -4

f(-4) = 4 - 2(-4) = 12

x = 0

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

x = 5

f(5) = 4 - 2(5) = -6

Answer:

$578.33

Step-by-step explanation:

To get 5% of the original cost you need to multiply by 0.05

550.79 • 0.05 = 27.5395

27.5395 is 5% of 550.79

Since the price is marked up 5% you will need to add 27.5395 to 550.79

550.79 + 27.5395 = 578.3295

Then you will round your answer to 578.33
