Answer:
1) Yes
Product of Means = Product of Extremes
4 × 21 = 7 × 12
84 = 84
2) No
Product of Means = Product of Extremes
2 × 2 = 3 × 3
4 ≠ 9
3) No
Cross multiplying
3 × 6 = 4 × 8
18 ≠ 32
4) Yes
Cross Multiplying
1 × 25 = 5 × 5
25 = 25
Given:
The figure of a square base pyramid.
To find:
The area of volume of the pyramid.
Solution:
The area of square base is:



Area of one triangular side of the pyramid is:



Now, the total surface area of the pyramid is:




Therefore, the surface area of the pyramid is 672 square m.
The volume of the pyramid is:

Where, B is the base area and h is the vertical height of the pyramid.
Substituting
, we get



Therefore, the volume of the pyramid is 512 cubic meters.
Hence the correct option is d.

Answer:
James town is 5 meters higher than Takoradi
.
Step-by-step explanation:
Given:
Height of James town = 2 meters below sea level
Height of Takoradi town = 7 meters below sea level
To find:
How much higher is James town that Takoradi = ?
Solution:
As we can see the standard of height is how much the town is below the sea level.
So, the height of town having lesser value will be at a higher level.
Value of Height of James town is lesser than that of Takoradi town.
Therefore, James town is at a higher level.
Difference of height = 7 meters - 2 meters = 5 meters
So, the answer is:
James town is 5 meters higher than Takoradi.
Answer:
60
Step-by-step explanation:
using rise over run method, from (0,20) to (1,80) the line slants up by degree of 60 per one unit so the slope is 60.
