Answer:
D
Step-by-step explanation:
You have to have exactly the same thing underneath the radical. So for example in choice A you have sqrt(2) and sqrt(3) underneath the radical. They are not the same. Choice A is not the answer.
Choice B has the same problem sqrt(5) is not the same thing as sqrt(3) and choice B is not the answer.
Choice C has sqrt(5) and sqrt(6) as your choice. They are not the same. C is not correct.
D is the answer. Both choices have sqrt(7) as the radicals. They are both 7. They are the same.
Answer:
4.422 (2 repeats)
Step-by-step explanation:
68/9 - 47/15 = 4.422
If you mean average, then it's quite simple.
Usually when you want to find the average of something, you add them up all together and divide by how many there are.
For example, the numbers:
12, 69, 35, 67, and 2.
Steps:
1.) Add them. 12 + 69 + 35 + 67 + 2 = 185
2.) 185 divided by 5.
3.) Answer: 37
If you would like to know how much do you save per month, you can calculate this using the following steps:
your expenses: 36% of 2,847.69 = 36% * 2,847.69 = 36/100 * 2,847.69 = 1,025.17
2,847.69 - 1,025.17 = 1,822.52
saving 40% of your discretionary money: 40% of 1,822.52 = 40% * 1,822.52 = 40/100 * 1,822.52 = 729.008 = 729.01
The correct result would be: You can save 729.01 per month.
Answer:
(x + 4)² + (y - 7)² = 20²
Step-by-step explanation:
Graphing form
(x - h)² + (y - k)² = r²
(h, k) is the center = (-4, 7)
r is the radius = 20
-----------------------------------
Plug in the givens
(x + 4)² + (y - 7)² = 20²
