For 6 hours charges $330
for 9 hours charges x
---------------------------------
x = 9*330/6 = 495 so choice C. is right
First, let's convert all of these numbers to decimal form:
(This will make it much easier to compare.)
- 0.6, - 0.625, - 0.4117, - 0.72
Now we can list them from least to greatest!
-0.4117, - 0.6, -0.625, -0.72
And don't forget to convert the selective decimals that we converted earlier back into fractions!
Therefore, the final list would be:
- 7/17, - 0.6, - 5/8, - 0.72
Hope this helps!
Answer:
85%
Step-by-step explanation:
There are two ways to solve this.
1. You can find the percent of birds, and then subtract that from 100%.
To find the percent of birds, divide 45/300 or make the denominator 100 by dividing both parts by 3.
45/300 (as a fraction)
=15/100
That is the same as 15%.
Subtract that from 100% and you get 85%.
2. You find the number of non-bird animals and make that a percent.
300-45=255 non-bird animals
255/300 (as a fraction)
=85/100
That is the same as 85%.
So either way, the answer is 85%.
Answer:
(6x^2 - 5)(x^2 + 2).
Step-by-step explanation:
6x^4 - 5x^2 + 12x^2 - 10
= 6x^4 + 12x^2 - 5x^2 - 10
= 6x^2(x^ + 2) - 5(x^2 + 2)
(x^2 + 2) is common so we have:
(6x^2 - 5)(x^2 + 2).
