Answer:
Step-by-step explanation:
In this problem, we are told that the mass of 1 grain of sand is:
The total mass of N grains of sand will be therefore
where
N is the number of grains of sand
M is the total mass
Here we have a number of grains of sand equal to
Therefore, the total mass of the grains of sand is:
Answer:
The area of the smaller triangle is 75.
Step-by-step explanation:
Here, the ratio of the sides of the similar triangle are 5 : 6
The area if the larger triangle = 108
let us assume that the area of the smaller triangle = m
By the Theorem:
In two similar triangles, the ratio of the areas of similar triangles is the square of the ratio of their sides.
Similarly, here
= \frac{m}{108}[/tex]
⇒
or,
⇒ m = 75
Hence, the area of the smaller triangle is 75.
