Answer:

-5/2

2/3

Step-by-step explanation:

Make a triangle with two points on the line.

Count the squares to get rise (change in y) and run (change in x).

Slope=rise/run

For (3), pick two easy points on the line. For example, (-1,2) and (-3,7).

Slope=(y1-y2)/(x1-x2)

Point1 = (-1,2): y1=2 and x1=-1

Point2=(-3,-7)): y2=7 and x2=-3

Slope= $\frac{2-7}{-1-(-3)}$

=-5/2

Same process for others. Slope is about incline (think driving up a hill), so for (5) the slope is 0 because the line is horizontal.

number has 6 digits smallest digit is 0.01 largest digit is 8,000 digit in the tens is 2 less than digit on the hundreds the sum

monitta

What a problem! We know that the largest digit is 8,000, and the smallest is 0.01. The number is 8,_ _ _._1. If the tens is 2 less than the hundreds digit, then if we make the hundreds digit x, the tens are x-2. The tens digit plus the hundreds digit is the thousands digit, so x+(x-2)=8. Let's solve: x+(x-2)=8. Eliminate parentheses: x+x-2=8. Use inverse operations:x+x-2+2=8+2. x+x=10. Combine terms: x+x=2x. 2x=10. Divide: 2x/2=10/2. x=5.

So the hundreds digit, x, is 5. And the tens are x-2: 5-2=3. The number is 8,53_._1. And what's the only number that means the same, no matter what place value you put it in? 0! This is the tenths place: 8,53_.01. The remaining digit is the ones. The largest one-digit even number is 8, so our number is 8,538.01!

Answer: 8,538.01

A major fishing company does its fishing in a local lake. The first year of the company's operations it managed to catch 75,000

BigorU [14]

Answer:

The total amount of fishes caught is 414,519 fishes

Step-by-step explanation:

Here, given the percentage decrease in the population of fishes, we want to know the total amount of fishes caught by the company in the first 7 years.

First year, we have 75,000 fishes

Second year, we would have 75,000 - (8% of 75,000) = 75,000 - (0.08 × 75,000) = 75,000 - 6,000 = 69,000

Third year, we would have 69,000- (0.08 × 69,000) = 69,000 - 5520 = 63,480

Fourth year, we would have 63,480 - (0.08 × 63,480) = 58,401.6

Fifth year, we would have 58,401.6 - (0.08 × 58,401.6) = 58,401.6 - 4,672.18 = 53,729.472

Sixth year, we would have 53,729.472 - (0.08 × 53,729.472) = 53,729.472 - 4,298.3578 = 49,431.114

Seventh year, we would 49,431.114 - (0.08 × 49,431.114) = 45,476.625

The addition of all these values will give the total number of fishes caught = 75,000 + 69,000 + 63,480 + 58,401.6 + 53,729.472 + 49,431.114 + 45,476.625 = 414,518.8 = 414,519 fishes to the nearest whole number

Please help. Will give brainliest. And I need step by step please

Answer: 500cm squared

Step-by-step explanation:

To figure out the area, here are the steps

First, seperate the parallelogram into 2 triangles and a rectangle.

Secondly, we see it has figured out the area of the triangle which is 25, so we can assume that the other triangle is also 25. So the area of the two triangles are 25 + 25 = 50

Then, if we look at what it has labeled, we would know that the length of the parallelogram is 50, BUT this 50 contains ONE length of the triangle, which means to get the actual length of the rectangle, we must subtract a length of a triangle from 50.

That's 50 - 5 = 45. Therefore the area of the rectangle is (length times width) 45 ✕ width = the area of the rectangle.

Now we realize that we don't know the width of the rectangle, we can figure that out by back-tracking from the area of the triangle.

We know that area of a triangle is length times height divided by 2, so 25 ✕ 2 divided by legth would get us the height of the triangle. 25 ✕ 2 ÷ 5 = 10

Now we can figure out the area of the rectangle. 45 ✕ 10 = 450

Add the rectangle and the triangles together, you get -- 450 + 50 = 500 (cm squared）
