Answer:
2450
Step-by-step explanation:
First you will divide;
200÷4=50
Then you multiply;
50×9=450
Last you add;
2000+450=2450
Hope this helps :D
Canceling units is also called unit analysis.
This is also called dimensional analysis.
What is a unit of analysis in statistics?
- The unit of analysis is the entity that you're analyzing. It's called this because it's your analysis (what you want to examine) that determines what this unit is, rather than the data itself.
- Because it is the analysis you do in your study that determines what the unit is.
- For instance, if you are comparing the children in two classrooms on achievement test scores, the unit is the individual child because you have a score for each child.
For example -
1 ft = 12 in
3 ft = 
3 ft = ( 3 * 12 ) in ⇒ 36 in

Answer:
d=6h
Step-by-step explanation:
Speed of the raft= 6 miles per hour
Total distance (d) of the raft= rate × number of hours
d=r*h
Independent variable is the number of hours(h)
Dependent variable is the distance (d)
Equation for the situation
d=r*h
d=distance
r=rate
h=number of hours
From the question,
r=6 miles per hour
Therefore,
The equation is
d=r*h
d=6*h
d=6h
Answer:
I am having a hard time reading the letters, so I hope this makes sense. I think that the numbers for the top triangles is given is 6 and 3. That means that the scale factor from the little to the big is 2 and from the big to the little is 1/2. It is the same for the bottom triangles.
Step-by-step explanation:
If the triangles are similar the scale factors will be the same for all three corresponding sides of the triangle. You find the two sides that are corresponding and ask yourself what do I have to multiple the side of of triangle to get the new triangle.
If one side is 3 and the other triangles side is 6. I am asking myself what do I have to multiple 3 by to get 6? 2. That is my scale factor.
3x = 6
x = 2
The scale factors are always reciprocals of each other. If I go the other direction I can write the equation
6x = 3 and when I divide both sides by 6, I get a scale factor of 1/2.
The bottom triangles:
2.5 x = 5
x = 2
and
5x = 2.5
x =1/2
2 weeks = 14 day
14 * 15 = 210 seconds
210/60=3 hours and 30 minutes or 3.5 hours.
