Answer:
No
Explanation:
The distance between the two points on the ground = 43km
First, we calculate the distance between the two points in meters.
• 43km = 43,000 m.
Next, determine the distance it will take using the scale.
The distance between the points using the scale is 1.72m.
Next, we see that the dimensions (1.32 m by 0.85 m) are smaller than the length.
As a final check, calculate the length of the diagonal of the map. The diagonal is usually the longest part.
Since 1.57m is still less than 1.72m, the two points cannot be placed on the map.
Answer:
The number is 2.26
Step-by-step explanation:
Let The given numbers be x
Now according to question :
x : 18 = x² - 5
I.e x = 18 × ( x² - 5 )
or, x = 18 × x² - 90
or, 18 x² - x - 90 = 0
Or, From quadratic equation , the value of x
x =
Or, x =
Or, x =
So, x =
∴ x = = 2.26
Hence The number is 2.26 Answer
