Negative Decimals On The Number Line

Answers

Answer 1

Answer:

-0.58

Step-by-step explanation:

The number gets less as you move to the bottom. Each dash represents 0.01. The dot is 3 lines below -0.55, so you would do -0.55 - 0.03, and the answer is -0.58.

I hope this helps and please mark me as brainliest!

Answer 2

Answer:

-0,56

Step-by-step explanation:

As you go up, the numbers tend to get larger. -0.5 is larger than - 0.6

So considering where the dot is on the number line, you have to subtract - 0.02 for every horizontal line you cross.

Another way of putting this is you must add 0.02.

For me, it is easier to add 0.02 because the amount is getting bigger. Why 0.02? it is because there are 5 horizontal notches between -0.6 and - 0.5. Each notch must be -.1/5 = -0.02

First notch: -0.6 + 0.02 = -0.58

Answer: Second notch: -0.58 + 0.02 = -0,56

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?

Answers

I’m pretty sure the answer should be 1,710 if not i’m sorry

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

Hope you understood the answer and I hope it helps you :)

Responses
A 3939
B 1616
C 3737
D 1313
E 17

Answers

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

16
2+3+5+9+17+22+31+39=128
128/8=16

1/2 divided by 3/4= 1/a multiplied by b/c = d/e

To find the number of rabbits after a certain number of weeks, we can substitute the number of weeks into the equation r = 25 + w and solve for r.

For example, after 1 week, we have:

r = 25 + w = 25 + 1 = 26

So there are 26 rabbits after 1 week.

Similarly, after 8 weeks:

r = 25 + w = 25 + 8 = 33

So there are 33 rabbits after 8 weeks.

Slope = (2 - (-3)) / (-5 - 5) = 5 / -10 = -1/2

Since we know the slope and a point that belongs to the line, we can write this in point-slope form which will be:

y - 2 = -1/2(x - (-5))      *I used (-5, 2) but it doesn't matter which point you use

y = -1/2(x + 5) + 2

y = -1/2x - 1/2
