Step-by-step explanation:
I did this a few times and this is correct.
Subtract (10 into fifths) from (20 divided into half)
= (20 divided into half) - (10 divided into fifths)
=(20/2) - (10/5)
If you need to solve the expression:
=10-2
=8
Hopes this helps :)
Answer:
42.8°C
Step-by-step explanation:
To convert from degrees centigrade to degrees fahrenheit, we use this formula;
(C ×
) + 32
Where C is the temperature in degrees centigrade.
So,
(C ×
) + 32 = 109°F
C = 109 - 32
C = 77
C = 77 ×
= 42.77777778°C
It equals 42.8°C (rounded up to nearest tenth of a degree centigrade)
The square root is 11.0905.

Answer: Choice A) 212 square meters</h3>
========================================================
Explanation:
14.10 has four sig figs. The 0 at the end is significant. This measurement is accurate to the hundredths place. If the author wrote 14.1, then it would be accurate to the tenths place with three sig figs.
15.0 has three sig figs. The 0 is significant. If they wrote 15 or 15. then we'd be dealing with 2 sig figs instead; however they placed the 0 there to tell the reader "this measurement is accurate to the tenths place"
---------------------
Multiply the values given
14.10*15.0 = 211.5
Round that to three sig figs. We pick the smaller sig fig count to round to since we cannot be certain it is accurate to four sig figs. In a sense, we pick the weakest link and use that to determine rounding when it comes to multiplication and division.
This means 211.5 rounds to 212
