I need help it is confusing?????
algol [13]

Answer:

1. 7

2. 15

3. 181

Step-by-step explanation:

Just make sure that you make your denominator a whole number

1. 9.8/1.4....,you multiply by 10...which only removes the comma but it keeps the structure of the question

Always remember that what you do to the denominator...you also do to the numerator

: 9.8/1.4 × 10/10 = 98/14 = 7

2. 40.5/2.7....,you multiply by 10

: 40.5/2.7 × 10/10 = 405/27 = 15

3. 3.62/0.02...., you multiply by 100

: 3.62/0.02 × 100/100 = 362/2 = 181

A square wall is covered with sqare tiles. There are 85 tiles altogether along the two diagonals. How many tiles are there on th
olchik [2.2K]

Answer:

There are 1849 tiles on the whole wall.

Step-by-step explanation:

If there are 85 tiles along the two diagonals, we can use the following rule:

\frac{85+1}{2}=43

So we have 43 tiles in the first diagonal and 85-43 = 42 in the second diagonal.

Now, as we have a square the side will have 43 tiles so the total area will be cover with:

A=43*43=1849

Therefore, there are 1849 tiles on the whole wall.

I hope it helps you!
