I dont understand im sorry i wish i could help
Answer:
1. Northwest 2. Southeast
Step-by-step explanation:
So, basically, here we have to compare two values. When we want to know how many times one value is bigger or smaller than the other one, we use division.
Here, we are given the value of average soil saturation in the entire county from the last year (0.24)and we want to compare it to this year's values.
First, we know that last year's value was 1.2 times greater than one of the region's this year. To find that value, the easiest thing to do is to divide:
0.24 / 1.2 = 0.2
That means that 0.24 is 1.2 times bigger then 0.2. Looking at this year's results we find that 0.2 was the saturation of NORTHWEST region.
For the second part of the question, we'll do the same thing. Now, last year's value was 0.25 of one of the region's this year. To find it, again we divide:
0.24 / 0.25 = 0.96
Again, looking at this year's results, we see that 0.96 was the saturation of SOUTHEAST region.
Answer:
Combination, but keep in mind that if the committee had two open positions, say President and Secretary, it would be a permutation
Step-by-step explanation:
The first thing to keep in mind is the difference between combination and permutation.
The main difference is that in the combinations the order does not matter, whereas in the permutations the order does matter.
Combination example:
Choose 7 people for a project.
Example of permutation:
Choose 5 men for each specific role in a soccer team.
Therefore, "group of 5 senators is chosen to be part of a special committee" is a combination, but keep in mind that if the committee had two open positions, say President and Secretary, it would be a permutation.
Using distrubutive property, the answer would be 8x+-18=14
Ok so the area of the frame is 18*12 = 216cm^2
Let’s suppose the width of the frame is x
The total area (painting and frame) is (2x+18)(2x+12) and this is equal to 432
4x^2 + 60x + 216 = 432
4x^2 + 60x - 216 = 0
x^2 + 15x - 54 = 0
(x+18)(x-3) = 0
Therefore x = {-18,3}
Since width of the frame has to be positive, the width has to be 3cm
