Answer:
5 pieces of 40 cm
Step-by-step explanation:
A Bar of steel is 340 cm long Issa cuts two 55cm lengths of the bar
He then cuts the rest into as many 40cm lengths as possible
Work out how many 40cm lengths of bar Issa cut.
so
340cm - 55 cm - 55 cm = 230 cm remains
<u>230 cm </u>to cut into 40 cm as many as possible
40 cm
therefore, there are 5 pieces of 40 cm
The only true inequality is <u>-3 1/2 > -4.5</u>
Answer:
29.8 × 10⁸
Step-by-step explanation:
The average life span for human is 79 years
And healthy heart beats 72 times a minute
Now,
Total number of minutes in 79 years = 79 × 365 × 24 × 60
therefore,
The total number of times heart beats in the life span
= 72 × 79 × 365 × 24 × 60
= 2989612800 times
now, to convert it into an answer with 10⁸
divide the result with 10⁸
Hence,
The total number of times heart beats in the life span = 29.8 × 10⁸ times
