1. 1m=100 cm
1m^2= 10,000 cm^2

2. if 3 pencils are 1.65, then 1 pencil is 1.65/3=$ 0.55
7 pencils will cost 7* $0.55= $3.85

3.1 ha is 10,000 m^2, and 1 soccer filed is roughly 100m *110 m
so it makes sense that 1 ha is roughly 2 tennis courts
4.odd numbers between 20 and 30 are
21,23,25,27,29
lets add the,m
21+23+25+27+29=125

satela [25.4K]

Answer: She needed 144 square feet of carpet.

Step-by-step explanation:

Given : Maria is buying new carpet. Her bedroom is in the shape of a square.

The length of each side is 12 feet.

We know that the area of square = $(side)^2$

So , the area of the bedroom = $(12)^2$ [which is an exponential expression]

Simplify it

The area of the bedroom = $12\times12=144\ \text{ft}^2$

Also, the carpet she needed = Area of the bedroom.

Thus , She needed 144 square feet of carpet.

if the cost price of 10 tables is equal to the selling price of 16 tables , find out the gain or loss percentage

Dovator [93]

Hi,

To solve this problem, Let us take the LCM of 10 and 16 which will come 80.

Now suppose the cost price of 10 tables =₹n CP of 80 tables will be ₹ 8n

According to the question, CP of 10 tables is equal to the SP of 16 tables, then

the SP of 16 tables will also be ₹ n.

So, SP of 80 tables will be ₹ 5n

So, Loss = CP-SP

→ 8n - 5n = ₹ 3n

Loss%= (3n×100)/8n

Loss%= 37.5%.

Hence the correct answer will be a <u>loss of 37.5%.</u>
