<u>Answer:</u> The final answer must have only one decimal place.
<u>Step-by-step explanation:</u>
Significant figures are defined as the figures present in a number that expresses the magnitude of a quantity to a specific degree of accuracy.
We are given:
An addition problem having values (34.530 g + 12.1 g + 1222.34 g)
<u>The rule that is applied for the addition and subtraction is:</u>
The least precise number present after the decimal point determines the number of significant figures in the answer.
For the given problem, the least precise number after the decimal is '1'
Evaluating the value: (34.530 g + 12.1 g + 1222.34 g) = 1268.97 ≈ 1269.0
Hence, the final answer must have only one decimal place.
<em>when we solve the equation it will become
x</em>² + 9x<em>= 0
now here a = 1 , b = 9 and c = 0
by using quaderatic formula
x = -b +,-</em>√<em>b </em>²<em>- 4ac / 2a ( 2a is divided by all terms )
by putting values
x = - 9 +,</em><em>- </em>√<em>81 / 2(1) ( </em>√<em>81 = 9)</em><em>
x = -9 + 9 / 2 and x = -9 -9 /2
x = 0 and x = -18 /2 = -9
now there are two values for x one is- 9 and other is 0
so we put -9 as the value of x then answer will be zero..</em>
Just turn 20% into a decimal and multiply it by 65 grams, then add that number to 65 grams.
So 20%=.2, therefore 65 multiplied by .2 equals 13. Add that number (13) to 65 and you get 78!
The patient will receive 78 grams of the new dose!
Hope this helps!
