12,50,000cm
Step-by-step explanation:
Given that 1cm=500000cm
Then using unitary law, we get
Actual distance=2.5cm=2.5×500000=12,50,000cm
7 hours
explanation:
30>or equal to 3h+9
subtract non on both sides:
21>or =to 3h
divide by 3:
7>or=to h
Answer:
Given, DF and DE are midsegments of ABC. so D is the mid point of AB and F is the mid point of AC.
Considering AB,
Then DE is parallel to AC, as mid-segments are parallel to the non included side of the triangle.
Also, according to corresponding angle theorem,
Then,
As,
According to similarity of two triangles,
The slope is the change in y over change in x
Given the points (1,8), (2,11), (3,14), (2,17) we can use the table to figure out what our equation will be
Notice on the table as you go on the y term from 8 to 11 to 14 to 17 you are having a constant rate of change of 3. So that’s your change in y
On the left side which is your x, you are going up by 1 every time because it’s {1,2,3,4} So your change in x is 1
Your slope or m in y=mx+b can be found by using the following formula
Change in y/change in x
So here our change in y is 3 and our change in x is 1. So that means our slope is
m=3/1 = 3
y=3x+b
To find b, you can plug in one of the points. Let’s use (1,8). So x=1 and y=8. Now we can plug these in and solve for b.
8=3(1)+b
8=3+b
Subtracting 3 on both sides we have
b=5
Therefore given y=3x+(b) we can plug b in to obtain the following equation
y=3x+5. So that’s your answer
I hope this helps!!! Mark for brainliest!!!
