Answer:
Step-by-step explanation:
80 minutes.......8 minutes played commercials....that means (80 - 8) = 72 minutes played music
so the ratio of music to commercials is : 72/8 which reduces to 9/1...so the ratio is 9:1 <=== ur answer
** pay attention to the wording, because if it would have asked for the ratio of commercials to music, it would have been 8/72....ratio would be 1:9
Answer:
C and D
Step-by-step explanation:
The quadratic formula is
x= (-b±√b²-4ac)/2a
The formula uses the numerical coefficients in the quadratic equation.
The general quadratic equation is ax²+bx+c where a, b and c are the numerical coefficients
So, lets try and see;
A.
But due to the fact that in this equation you have x⁴, the equation is not a quadratic equation thus can not be solved using this formula
B
C
D.
From the checking above, the equations will be C and D
Answer:
It will be 2.27
Since the 8 in 2.268 is larger than 5, the 6 will turn to the next number. So, the answer will be 2.27.
384 is between 380 and 390
<span>2 liters" only shows one significant figure. This "2 liters" can be anything from 1.9 liters to 2.1 liters. Actually, to be more strictly correct, the 2 liters can be between 1.5 liters and 2.4 liters. Either of these bounds would be 2 to the nearest ONE's place.
The biggest percent error would be between 2 and 1.5, which is a volume error of 0.5 liters.
Thus: (0.5/2)*100=25% C: is your Answer</span>
