Answer:

It will take 12 weeks to pay for the DVD players.

Step-by-step explanation:

Given in the question that,

total cost of DVD bought by Adela = $210

Step 1

Adela makes a down payment of $30

$210 - $30 = $180

Remaining cost = $180

Step 2

Adela pays $15 each week

$15 = 1 week

$180 = ?

$1 = 1 week/15

$180 = 180/15 week

        = 12 weeks

A case of Scout cookies has 10 cartons. A carton has 12 boxes. The amount you earn on a whole case is 10(12x) dollars.
Katen [24]

Simplified expression: 120x dollars

Step-by-step explanation:

Given,

Number of cartons in case of Scout cookies = 10 cartons

Number of boxes in carton of Scout cookies = 12 boxes

Amount earned on whole case = 10(12x)  dollars

To simplify the expression, we will multiply 10 by 12x

Amount earned on whole case = 120x dollars

Simplified expression: 120x dollars

cups of flour per batch. If she wants to make 2/3

a batch of cookies, how much flour should she use?"

1 1/2 Cups, if she wants to make less than the original recipe, she would need less flour, you have to divide.

The table represents an exponential function.
Minchanka [31]

we know that

The multiplicative rate of change of the exponential function between two points is equal to

[f(b) / f(a) ] / (b-a)

Let

A(1,6)\\B(2,4)

we have that

f(a)=6\\f(b)=4\\a=1\\b=2

substitute in the formula

[4 / 6 ] / (2-1)=4/6=2/3

Let

A(3,8/3)\\B(4,16/9)

we have that

f(a)=8/3\\f(b)=16/9\\a=3\\b=4

substitute in the formula

[(16/9) / (8/3) ] / (4-3)=48/72=2/3

therefore

<u>the answer is the option</u>

B.) 2/3

Game 1 gives you 200 points every time you score. Game 2 doubles your points every time you score (2, 4, 8, and so on). In which
nignag [31]
Its depends on how many times you score during the game 

in second game the number of points increases  as a geometric sequence
with common ratio 2

so for example if you score ten times in first game you get 2000 points


if you score 10 times in Game 2 you score   2 * (2^10) - 1  =  2046 points

so playing 10 or more games  is best with Game 2.  Any less plays favours gane 1.

Machines A and B always operate independently and at their respective constant rates. When working alone, Machine A can fill a p
pychu [463]

Answer:

The value of x is \frac{10}{3} hours.

Step-by-step explanation:

Machine A = 5 hours

Machine B = x hours

Machine A and B = 2 hours

Using the formula: \frac{T}{A}  + \frac{T}{B} = 1

where:

T is the time spend by both machine

A is the time spend by machine A

B is the time spend by machine B

\frac{2}{5}  + \frac{2}{x}  = 1

Let multiply the entire problem by the common denominator (5B)

5x(\frac{2}{5}  + \frac{2}{x} = 1)

2x + 10 = 5x

Collect the like terms

10 = 5x - 2x

10 = 3x

3x = 10

Divide both side by the coefficient of x (3)

\frac{3x}{3}  = \frac{10}{3}

x = \frac{10}{3} hours.

Therefore, Machine B will fill the same lot in \frac{10}{3} hours.
