What does 2.6x10 to the7 th power
ss7ja [257]
This is called scientific notation. To simplify, just do 10 to the 7th (1 with 7 zero's behind it) to get 10,000,000 (10 million) then multiply that by 2.6 to get your final answer:
26 million or 26,000,000


Just so you know, picking a brainliest answer gives YOU back points, and I kind of need the rank upgrade, as it's kind of embarrassing being Ambitious with more than 9 times the amount of points needed and around 7 times the number of brainliest answers.

I think you doubled them

ratio of dogs to cats=3:2

30 animals total

3+2=5 units
30=5unit
divide by 5
6=1unit

dogs=3 unit
6=1unit
times 3
18=3unit=dogs

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! :)
