Answer:
273/1000
Step-by-step explanation:
Answer:
A 92/2
Step-by-step explanation:
To find the constant of proportionality
y = kx
Divide both sides by x to isolate k
y/x =k
Taking the point (2,92) where x =2 and y = 92 and substituting into the equation
92/2 = k
Answer:
Your answer is 63
Step-by-step explanation:
First lets find the area of the rectangle:
To find the area of a rectangle your multiply the length by the width. In this case it is 5 and 9 so..
5 x 9 = 45
Now to find the area of the triangle:
Formula for triangle: 1/2(bh)
9 is your height to find the base subtract 5 from 9:
9 - 5 = 4
Now divide that by 2:
4 / 2 = 2
2 is your base
Now we know the base and height solve:
1/2(2 x 9)
1/2(18)
18 / 2 = 9
multiply 9 by 2
9 x 2 = 18
Now add your areas to find the final area:
45 + 18 = 63
By similarity of triangles we have the following relationship:
(YZ) / (XZ) = (ef) / (df)
Substituting values we have:
(10) / (15) = (8) / (df)
Clearing we have:
df = (15/10) * (8)
df = 12 meters
Answer:
The value of DF is given by:
df = 12 meters
