Natural ventilation unlike fan forced ventilation uses the natural forces of wind and buoyancy to deliver fresh air into buildings
Question:
John read the first 114 pages of a novel, which was 3 pages less than ⅓ of the novel. Write an equation to determine the total number of pages (P)
Answer:
114 = ⅓P - 3
Explanation:
Given
Number of pages read = 114
Total pages in novel = p
The relationship between the pages read by John and the total pages is analysed as follows:
3 less than ⅓ of total pages means:
⅓ of total pages - 3
Recall that P represents the total pages in the novel
So, the expression becomes
⅓ * P - 3
⅓P - 3
This means that the pages read by John is ⅓P - 3
This implies that the equation to determine the number of pages in the novel is
⅓P - 3 = 114
Solving further to get the actual number of pages;
Multiply both sides by 3
3(⅓P - 3) = 114 * 3
3 * ⅓P - 3 * 3 = 114 * 3
P - 9 = 342
Add 9 to both sides
P - 9 + 9 = 342 + 9
P = 351
Hence the number of pages is 351
Answer:
The composition of Composite of Volume basis is 2.154% Copper and 97.83% Rubber.
Explanation:
Let us assume that the total mass of composite is 100 lbm So as per the given conditions
- 15 lbm is copper and 85 lbm is rubber.
- Density of rubber is 70 lbm/ft3
- Specific gravity of Copper is 9
So As per the formula of specific gravity

here density of water is 62.4 lbm/ft3
Solving for Density of Copper gives

For composition on volume basis, volume of individual components and composite are calculated as

The composition is given as

So the composition of Composite of Volume basis is 2.154% Copper and 97.83% Rubber.
