Hello there! The answer is the first option, 31/55.

To solve this, we don't even need to do any math. Note that fractions with the same numerator and denominator will be equal to 1.

Knowing this and looking at our second and fourth options, 55/55 x 111 and 31/31 x 111, these problems are the same as 1 x 111, which results in 111, which is not less than, leaving us with the third and first options.

The third option is 55/31, meaning we have more than a whole, so we are multiplying by a number greater than 1, making our answer over 111 and this option not correct.

This leaves the first option as your answer!

What is 10 to the second power as a decimal
natka813 [3]

Answer:

0.01

Step-by-step explanation:

If you convert 10 into a decimal it's just 0.1, multiply 0.1 by itself only one time because the exponent is 2 and you get 0.01

Greg studied for 12 minutes. This is 40% of the time he wants to study today. How many more minutes does Greg need to study toda
dolphi86 [110]

Answer:

18 More Minutes

Step-by-step explanation:

Hi,

I think I can help.

What I would first do here is try to find the value of 10% relative to the 12 minutes. If we find what 10% is we can multiply that to get 100% to find the total amount of minutes he wants to study. We can then subtract the time already studied to find our answer.

To do this we want to take the 40% we have and find 10. We can do 40/4 to find this since 40 divided by 4 is actually 10.

But if we do this we also have to do with to the number it is relating to / representing. Which is 12. (12 minutes = 40%)

So we can do :

40 / 4

=

10%

Also

12 / 4

=

3

So with this we can conclude that 10% of his total time is 3 minutes.

Now lets multiply this by 10 to get the 100% we are looking for so we can get the total amount of time he spent studying.

So :

10% x 10

=

100%

3 x 10

=

30 minutes

So his total time is 30 minutes of studying, but we have to find how many more minutes after his 12.

We can now simply take the total time and take off the time spent already to find this answer :

30 - 12

=

18 minutes

That is your answer, he needs to study 18 more minutes.

I hope this helps!

If you have any questions or concerns please comment or message me! :)

25) PLEASE HELP WITH QUESTION, WILL MARK BRAINLIEST + POINTS.
iogann1982 [59]
You take the three zeros and put them back with the x s 

(x-6)(x+5)(x-2)  they are reversed when you put them back in 

multiply the first two and get x^2+5x -6x-30(x-2) 
simplify to x^2-x-30(x-2)

Multiply it out again and get x^3-x^2-30x-2x^2+2x+60
finally simplify and get x^3-3x^2-28x+60 

So the answer is the first one
