Answer:
125
Step-by-step explanation:
Find the surface area of the table that Raj wants to cover.
Since the side table is a cube each side is identical.
Step 2:
Raj wants to cover 5 sides of the cube. Therefore the total surface area to be covered is 5 · 30 · 30 = 4,500 square inches.
Step 3:
Find the surface area of each tile.
The surface area of each tile is 6 · 6 = 36 square inches.
Step 4:
Find the number of tiles needed to cover the table.
4,500 square inches
36 square inches per tile
= 125 tiles
Raj will need 125 tiles to cover the table.

Answer: A star has six lines of symmetry.
Step-by-step explanation:
A star in a flat plane has one line of symmetry, but it can be divided into up to three different angles (120 degrees). A hollow sphere is symmetrical on the inside and will have six lines of symmetry. But if you cut across its middle at any slight angle, you'll also see six lines of symmetry. So the answer is that stars can have either 1 or 6 lines of symmetry depending on how they are measured.
Answer: First term = 11r and second term= 7s
The coefficient in first term = 11
The coefficient in second term =7
Step-by-step explanation:
The given expression 11r + 7s is with two terms i.e. a binomial expression with variables r and s
Here the first term = 11r
And the coefficient of r in term =11
The second term= 7s
The coefficient of s in second term=7
The coefficients are the numbers that multiply the variables .
