Answer:

1/3 feet

Step-by-step explanation:

We are given that

On a scale drawing

45 inches represented =75 feet

We have to find a scale of 1/5 inch how many feet represents.

To find the value in feet represented by  a scale of 1/5 inch we will use unitary method.

Using unitary method

45 inches represents =75 feet

1 inch represents =\frac{75}{45} feet

1/5 inch represents =\frac{75}{45}\times \frac{1}{5} feet

1/5 inch represents=\frac{1}{3} feet

Hence, a scale of 1/5 inch represents 1/3 feet

Answer:

1/3 or 0.33 feet

Step-by-step explanation:

This question can be easily answered by using simple proportions.

If 75 feet are represented by 45 inches on a scale, then the scaling factor from feet to inches is 45/75, or from inches to feet is 75/45

If we have 1/5 inch and want feet, just multiply by 75/45 to get

1/5*75/45=1/3=0.33 feet

Garvey's Electronic store is having a storewide sale. For a television set with a regular price of x dollars, a 15 percent disco
ratelena [41]
With the equation:
0.15 x = 30
x = 30 : 0.15 = $200
A regular price of TV is $200.
Which could not be used to determine x ( we shall plug in the value 200 ):
A ) 0.15 * 200 = 200 - 30
30 ≠ 170
B ) 0.85 * 200 = 200 - 30
170 = 170 ( correct )
C ) 200 - 0.15 * 200 = 200 - 30
200 - 30 = 200 - 30
170 = 170   ( correct )
D ) 0.15 * 200 = 30
30 = 30  ( correct )
Answer:
A ) 0.15 x = x - 30

Jamilia has a weather station in her backyard. She uses a rain gauge to track the total rainfall during two storms.
Zielflug [23.3K]

Answer:

1) The graph is linear, because it has an upwards slope of 5, we can tell because 3*5 =15 and 6*5=30.  

2)Real world meaning is the delta change. Hence in this case it's the increase in rain over time. More rain or raining harder as time progresses.

3)It is not linear because the second sample shows a slope of 7.5 meanwhile the third sample shows a slope of 6 which allows us to conclude that it is not linear.

4)The y intercept means the total rain that was present at the start of the recording which essentially means there was no rain when she started the experiment.
