Which expression is equivalent to -1/4 x + 1/2?
Anna71 [15]
The expression is given by:

-\frac{1}{4}x+ \frac{1}{2}

So we need to find an equivalent equation for this problem. Then, we will apply some mathematical rules:

Extracting the common factor 1/4, then:

\frac{1}{4}(-x+2})

Or extracting the common factor -1/4, then:

-\frac{1}{4}(x-2})

So, comparing these solutions with the answers about, there is no any answer that matches.

if the kinetic energy of an aeroplane moving at a velocity of 100m/s is 200j ,what is the mass of the aeroplane
Black_prince [1.1K]

Answer:

<u>0.04kg</u>

Step-by-step explanation:

Kinetic energy Formula: eK=0.5×m×v²

to work out mass

we can rearrange the formula and make it:

~m=eK÷(0.5×v²)

now insert the missing digits into the formula:

m=200÷(0.5×100²)

work it out, and you get your answer

m=0.04kg

Hopefully this helped-have a good day)
