Answer:
28/33
Step-by-step explanation:
We first let 0.84 be x.
Since x is recurring in 2 decimal places, we multiply it by 100.
100x=84.84
Next, we subtract them.
100x−x=84.84−0.84
99x=84
Lastly, we divide both sides by 99 to get x as a fraction.
x=84/99
=28/33
Answer:
the first one :)
Step-by-step explanation
If the number of negatives is an even number it would make it positive and if it is an odd number it would make it negative.
A product is negative when the number of negative numbers in the multiples is odd.
Therefore, options A and C gives negative products.
<u>solution</u>
W=f×d×cos theta
=25N×16m×cos 45°
=400Nm×cos 45°
=282.84J
W=f×d×cos theta
=25N×7m×cos 10°
=175Nm×cos10°
=172.34J
Total workdone=282.84J+172.34J=455.18J
Answer:
Equation C: 5/8x + 2..5 = 3/8x + 1.5 + 1/4x
Step-by-step explanation:
Let us go through each of the equations one by one.
Equation A: 
This simplifies to

which has infinitely many solutions.
Equation B: 
this simplifies to


which is exactly one solution.
Equation C: 
this simplifies to


There's no way this is going to be possible; this equation has no solutions.
Equation D: 
this gives


which is exactly one solution.
Thus we see that it is equation C that has no solutions.
