Answer:
5X + 24 = 79
Step-by-step explanation:
Sum means addition.
Five times a number(X) means 5X.
So 5X plus 24 equals 79.
Answer:
i) Line
ii) point
Step-by-step explanation:
Given is a number 3. We have to find the kind or kinds of symmetry
On seeing 3, we find that no vertical line can divide 3 into exactly two symmetrical figures.
But if we draw a horizontal line in the middle of 3, we get two symmetrical figures up and down the line.
Hence i) symmetric about a line
Next is imaging the middle of 3 end point.
At that point we find that the figure is symmetrical on all sides of the point
Hence there is also a point symmetry
Kinds of symmetry are
i) Line
ii) point
Answer:
Step-by-step explanation:
There are approximately 7.5 × 10¹⁸ grains of sand on earth.
There are approximately 7 × 10²⁷ atoms in an average human body.
A. There are more atoms in an average human body. When comparing the order of magnitude of each number 27 it greater than 18.
7 × 10²⁷ > 7.5 × 10¹⁸
B. Now we will calculate how many times more atoms are in a human body compared to grains of sand on earth.
=
≈ 1 × 10²⁷⁻¹⁸
≈ 1 × 10⁹
≈ 10⁹
There are approximately 1,000,000,000 atoms more in a human body compared to the grains of sand on earth.
