<span>25% is the correct answer, however instead of asking all us people here at yahoo what the answer is, next time you have a fraction you need to turn into a percent, simply divide the top number by the bottom number and multiply it by 100
1 divided by 4 is .25
.25 x 100 = 25%
and instead of multiplying by 100 each time, it's easier just to move that little decimal point to the right two spots! do 400+25%=425

Length is 6.8 feet, whilst width is 4 inches. The area is 4 x 6.8, which equals 27.2.
Answer:
substitute the unknown with the values given ie
3(3) - 4 (2)
you get 9-8
= 1
Ooh, quadratic equations!
alright, you see that zero at the end right?
that means you are trying to find the two factors
I'll write out the equation on paper to show you
take note of the signs in b and c
(ax²+bx+c)
because 5x is a negative (-5x), when you factor it out, the two, when multiplied together, should be negative. and because 30 is negative, the numbers will have two different signs. in other words, one will be positive and one will be negative.
now that that's cleared, we need to find all of the multiples of 30
there is:
30×1
15×2
10×3
and 6×5
of all of them, 10 and 3 would give you the -5 needed in -5× since one of them are going to be multiplied times 5
now let's factor it:
(5x+10)(x-3)
finally, divide everything
I wrote everything down for you to see
I cannot answer that, as I do not have the graph and need more info to answer.
