Answer:
4
Step-by-step explanation:
The equation of variation in which y varies jointly as x and z and inversely as the product of w and p is y=0.5(xz/wp).
Given that variable y varies jointly as x and z and inversely as the product of w and p,where y=7/28 where x=7,z=4,w=7 and p=8.
We are required to find the equation of variation.
To solve this problem we must apply the following procedure:
1) We have that y varies jointly as x and z and inversely as the product of w and p. Therefore we can write the following equation,where k is the constant of proportionality:
y=k(xz/wp)----------1
Now we have to solve for the constant of proportionality as done under:
k=ywp/xz-------------2
Using the values in equation 1.
k=(7/28)(7)(8)/(7)(4)
=0.5
Using all the values in the equation 2.
y=0.5(xz/wp)
Hence the equation of variance is y=0.5(xz/wp).
Question is incomplete.The following values should be included:
y=7/28 where x=7,z=4,w=7 and p=8.

8:30 because the 8:50 one is twenty minutes fast, the 8:00 one is half an hour off, and the 8:20 one is slow.
Answer:
Option c) Transitivity
Step-by-step explanation:
We are given the following information in the question:
If A exceeds B in some property and B exceeds C, then A must also exceed C.
We have to define the property shown by A,B and C.
Transitivity:
- It is a mathematical property which states that between three numbers if first and second share the property, second and third share the property, then according to transitive property, the property holds between first and third as well.
Thus, A, B and C here shows the transitive property.
The correct answer is
Option c) Transitivity
perimeter means to add up all the number around a surface so you are correct the answer is 12 because you are suppose to add up everything around the object so 7+5 which gives you 12
