Yes , your total savings on gas proportional to the number of beverages you purchases.

As for every beverage purchased , there is a saving of $0.20

If we show by an equation , where savings is s , and number of beverages is b

Than

s = 0.20 b

Answer:

Yes, there is a proportional relationship between the two.

Step-by-step explanation:

Given is :

Each liter of gas costs is $3, but with purchase of 1 beverage, we save $0.20 on gas. Similarly, if we purchase 2 beverage we save $0.40, If we purchase 3 beverages, we save $0.60 on gas.

Here, we can see that with each beverage, the savings on the gas is increasing. So, its proportional to each other.

If we want to show the relationship:

Let us suppose money saved be = x

Let us suppose the beverages purchased be = b

So, x=0.20b

Hence, yes the total savings on gas is proportional to the number of beverages you purchase.

Snowcat [4.5K]
10 * 6 = 60 by the time Zach joins so 125-60 = 65
Now 6 (lexie) +7 (zach)  = 13 (together) and 65/13 = 5. 
6*5 = 30 and 7*5 = 35. 35+30 = 65

Which numbers are 4 units from -2 on the number line
Artemon [7]

Let the number be x


Then the absolute value of the number from -2 should be 4


|x--2|=4


|x+2|=4


So either



(x+2)=4


x=4-2=2


Or


-(x+2)=4


x+2=-4



x=-4-2



x=-6



[tex] <B>The numbers are 2 and -6</B> [/tex[


They are four units away from -2 on the number line

A stockbroker has kept a daily record of the value of a particular stock over the years and finds that prices of the stock form
amid [387]

Answer:

$12.43

Step-by-step explanation:

Given :

Mean = $8.52

Standard deviation, = $2.38

Stock price which falls beyond 0.05 of the distribution is at the 95th percentile

The 95th percentile distribution has a Pvalue of 1.645 (standard normal table)

We obtain the value of x, with z = 1.645

Using the Zscore relation :

Zscore = (score - mean) / standard deviation

1.645 = (score - 8.52) / 2.38

Cross multiply :

1.645 * 2.38 = score - 8.52

3.9151 = score - 8.52

Score = 8.52 + 3.9151

Score = $12.4351

Stock price beyond 0.05 is $12.43

How many tiles of 10cm by a 6cm will be needed to pave a rectangular path of 5m by 3m
kherson [118]

Answer:

2500 tiles

Step-by-step explanation:

convert the path to the same units, one m = 100 cm

path= 500 cm x 300 cm

path area = 150,000 cm^2

each tile = 10x6 = 60 cm^2

150,000/60 = 2500 tiles

the length of a rectangle is twice its width the perimeter is 48 cm what are the dimensions of the rectangle
inysia [295]

Answer:

The length=16cm and the width=8cm.

Step-by-step explanation:

Given that the length is twice the breadth or width of the rectangle

Let's assume that the breadth of the rectangle is x.

Thus the length is 2x.

Given perimeter=48cm

The formula for the perimeter of a rectangle is 2(l+b) where l is length and b is breadth.

2(x+2x)=48

(3x)=48/2

3x=24

x=8cm

2x=16cm
