So using the conversion of 1 metric ton to kg, we see that there are 1000 kg in 1 ton. Then we can divide 40 by 1000 to find the decimal:
Then to convert this decimal to a percentage, we must multiply by 100%:
So now we know that 40 kg is 4% of 1 ton.
You should know that numbers are generally classified as real and imaginary. Under the real numbers, they are further classified into rational and irrational numbers. Under rational numbers, these include fractions and integers. Irrational numbers are in decimal forms that cannot be converted to fractions. Therefore, the difference between the two is that: <span>-1.96312.. is a real, irrational number while </span>√(-5) is imaginary. There is no value for a root of a negative number.
Answer:
Step-by-step explanation:
<em>(a).</em> 2( 2 )³ + a ( 2 )² - b ( 2 ) + 12 + ( 18 ) = 0
16 + 4a - 2b + 30 = 0
4a - 2b = - 46
<em>2a - b = - 23</em> ....... <em>( 1 )</em>
2 ( - 4 )³ + a ( - 4 )² - b ( - 4 ) + 12 = 0
- 128 + 16a + 4b + 12 = 0
16a + 4b = 116
<em>4a + b = 29</em> ........ <em>( 2 )</em>
<em>( 1 )</em> + <em>( 2 )</em>
6a = 6 , <em>a = 1</em>
4(1) + b = 29 , <em>b = 25</em>
<em>(b).</em> 2x³ + x² + 25x + 12 = 0
= <em>- 4</em> ( given: f(x) is divisible by x + 4 )
= <em>0.5</em>
= <em>3</em>
Answer:
5
Step-by-step explanation:
The numbers on the clock are separated by 30°, so the number 4 is at 120° after 12. The next number is 5, at 150°.
Answer:
2,48,000
Step-by-step explanation:
- Initial population of bacteria = 15,500
- Bacteria doubles after every 234 hours
- So, after 0 (zero) hours, no of bacteria = 15,500
- After 234 hours, no. of bacteria = 2(15,500) = 31,000
- After 468 hours, no. of bacteria = 2(31,000) = 62,000 (2*234 = 468)
- After 702 hours, no. of bacteria = 2(62,000) = 124,000 (3*234 = 702)
- After 936 hours, no. of bacteria = 2(124000) = 2,48,000 (4*234 = 936)
