8.5 cm x 12 cm ( 2 significant figures) BRAINLIEST!

Mathematics
1 answer:
Archy [21]3 years ago
3 0

Answer:

102

Step by step explanation (if non-calculator):

Times 8.5 by 10 to make 85. This'll now be 85 x 12.

If you can work this out, do so.

If not, then do 85 x 10 = 850.

Then, 85 x 2 = 170.

170 + 850 = 1020.

Now, divide 1020 by 10, since you multiplied 85 by 10 at the beginning.

1020 ÷ 10 = 102!

How is factoring a trinomial different than factoring a number?
JulijaS [17]

Answer:

Hope this answers the question.

Step-by-step explanation:

Factoring a number: If you use the number 10, for example, you have to find all the factors to factor it. 1, 2, 5, 10.

Factoring a trinomial: If you use the trinomial x^2 + 16 + 64, for example, to factor it you need to first find what numbers multiply up to 64 and also add up to 16. In this case, those numbers are 8, and so you get (x + 8)^2.

<h2>Answer:</h2>

<u>The length is</u><u> 250 meters</u>

<h2>Step-by-step explanation:</h2>

If we look at the left corner of the diagram we see a scale. According to the scale factor of the map

1 cm :1000 cm

The length of the lap on the map is 25 cm

So (25 × 1000) = 25000 cm

Since

1 meter = 100 centimeter

So the actual length of the lap = 25000 ÷ 100 = 250 meters
