Answer:
The Correct option is C ) 25
Therefore the value of x is 25 when y =40.
Step-by-step explanation:
Given:
Variable 'y' is directly proportional to the variable 'x'.
......Direct Variation
Where,
k = Constant of proportionality
To Find:
value of x = ? when y = 40
Solution:
First we need to find Constant of proportionality
When x = 20 and y = 32
Substituting the values we get
![32=k\times 20\\k=\dfrac{32}{20}=1.6\\\\k=1.6](https://tex.z-dn.net/?f=32%3Dk%5Ctimes%2020%5C%5Ck%3D%5Cdfrac%7B32%7D%7B20%7D%3D1.6%5C%5C%5C%5Ck%3D1.6)
Now when k =1.6 , y = 40 then x will be
![40=1.6\times x\\\\x=\dfrac{40}{1.6}=25\\\\x=25](https://tex.z-dn.net/?f=40%3D1.6%5Ctimes%20x%5C%5C%5C%5Cx%3D%5Cdfrac%7B40%7D%7B1.6%7D%3D25%5C%5C%5C%5Cx%3D25)
Therefore the value of x is 25 when y =40.
Answer:
0.5 < x < 16.5
Step-by-step explanation:
8.5 - 8.0 < x < 8.5 + 8.0 =
0.5 < x < 16.5

Answer:
p = 0.11 (rounded to 2 DP)
p = 0.111 (rounded to 3DP)
Step-by-step explanation:
p = 0.48³
p = 0.110592
Rounded to 2 DP
p = 0.11
Rounded to 3DP
p = 0.111
