I’m pretty sure the scale factor is 1/3 since it’s dilating. Cause 9/3=3 and 6/3= 2

The graph shows the relationship between the amount of time that a backpacker hikes and the distance traveled.

julsineya [31]

Answer:

The points represent that 5 miles were hiked in 3 hours.

Step-by-step explanation:

So, lets go over what we need to know.

The x coordinates is the time.

The y coordinates is the miles.

We have (3, 5)

This is (x, y)

x = 3, and y = 5. Considering what we know above, the time is 3 hours, and the miles is 5.

To fill in the boxes, it asks "Blank miles are hiked in blank hours"

We know 5 miles are hiked in 3 hours.

So the fill in for the first part is 5, and the fill in for the second part is 3.

Hope this helps!

T÷5/12= -3/10 Thank you if you help :)

skelet666 [1.2K]

Answer:

t = -1/8.

Step-by-step explanation:

t / 5/12 = -3/10 Invert the 5/12 and multiply:

12t / 5 = -3/10

Cross multiply:

12t * 10 = 5 * -3

120t = -15

t = -15/120 = -1/8.

Find an exponential model : Q is the population of bacteria in a Petri dish whose population was originally 150,000 but is tripl

Nadya [2.5K]

Answer:

150,000*3^t for 6 hour increments (t=1 is 6 hours t=2 is 12)

150,000*3^(t/6) for hourly increments, each t is 1 hour.

Step-by-step explanation:

Well super simply you could do 150,000*3^t where t is measured in 6 hour intervals. so t=1 is 6 hours, and to get 1 hour you would need to do t=1/6

If you want t to be an increase of every hour you would just need to adjust, like I showed before 1/6 gets one hour so 150,000*3^(t/6) would be the model where every t increases by 1 hour.

A map of a park says its scale is 1 to 100. What does that mean?

Alex777 [14]

A scale is a term that refers to the representative fraction for comparing the original length and image length of a given object. It means implies that every 1 unit on the drawing is equal to 100 units on the park.

A scale is a term that can be referred to as the representative fraction that compares the original length and image length of a given object. Types of scale include enlarged scale, reduced scale, and real scale.

Enlarged scale is a scale that is used when the size of a given object is to be increased.
Reduced scale is used when the size of a given object is to be decreased.
Real scale implies the exact size of a given object.

Scale can be expressed as;

Scale = $\frac{length on drawing}{original length}$

Thus a scale has no unit.

Therefore, the given question implies that every 1 unit on the drawing is equal to 100 units on the original park. Thus it is a reduced scale.
