Answer:
1 : 9.75 * 10⁷
Step-by-step explanation:
To find n, we have to divide the real distance by the scale distance. This is 7.8 * 10⁸ / 8 = 0.975 * 10⁸ = 9.75 * 10⁷ which means that the ratio is 1 : 9.75 * 10⁷.
1. multiply 250 by 10% (250 * .1= 25)
2. Then subtract 25 from 250 (250 -25= 225)
2. Then multiply 225 by 16% (225 * .16 = 36)
3. Add 225 + 36 = 261.
4. 261 is your final answer
Answer:
The magnitude of the necessary lifting force is 7.95N
Step-by-step explanation:
Force = mv^2/r
mass (m) = 2.00105kg, velocity (v) = 123m/s, radius (r) = 3810m
Force = 2.00105×123^2/3810 = 30273.89/3810 = 7.95N
In geometry, similar figures are those whose ratios of the corresponding sides are equal and the corresponding angles are congruent. In relation to the volume, we determine first the cube roots of the given and find the ratio as shown below.
s1 / s2 = cube root of (512/343)
= 8/7
The square of this ratio is the ratio of the areas of the figure. If we let x be the area of the smaller figure then,
(8/7)^2 = 192 mm²/ x
The value of x from the equation is 147 mm².
The area therefore of the smaller figure is 147 mm².
Answer:
Option C is the correct option.
Step-by-step explanation:
Considering the triangle ABC, the slope of the line CA is given by 
Again, considering the triangle CDE, the slope of the line EC is given by
Since CA and EC represents the same straight line so, we can write
Therefore, option C is the correct option. (Answer)
