Answer:

yes he is correct. he spent 125% more time

Step-by-step explanation:

his original time spent  was 20 hours

he spent a new time which is 25 hours

increased time = 25- 20 = 5 hours

% increase = increase/ original ×100%

%increase = 5/ 20 ×100%

= 1/4 ×100%

= 25%

total increment = 100 + 25 =125%

There are 10 marbles in the bag all together.
(8/10) = 80% of the marbles in the bag are white.

So if you pull a marble out of the bag, you have an 80% chance
of pulling a white one.

And if you do it many times, you expect that you'll pull
a white one out about 80% of the times.

   80% pf 45 times  =  0.8 x 45  =  36 times .

o-na [289]

Answer:

\large\boxed{5x(6x-x-2)}\\\\\boxed{-5(-6x^2+x+2)}\\\\\boxed{5(2x+1)(3x-2)}

Step-by-step explanation:

30x^2-5x-10=5(6x^2-x-2)=5(-1)(-6x^2+x+2)=-5(-6x^2+x+2)\\\\30x^2-5x-10=30x^2+15x-20x-10=15x(2x+1)-10(2x+1)\\\\=(2x+1)(15x-10)=(2x+1)(5)(3x-2)=5(2x-1)(3x-2)
