What is the approximate percent decrease when a fish count goes down from 850 to 500?

2 answers:

8 0

To get this, you divide the smaller number by the larger one and get 0.5882... 500 is about 59% of 850, so to find the percent lost, you subtract that from 100 to get 41% decrease

What’s the slope and y-intercept for 2y+5x-8=0

IrinaVladis [17]

Answer:

Slope- -5/2 Y Int.- 4

Step-by-step explanation:

You would first need rto put the equation in slope intercept form by subtracting -5x and adding 8 to both sides the you will divide two from each #. Then your equation will be in slope intercpt form which allows you identyify 4 as the y intercpt and -5/2x as the slope.

2y+5x-8=0

-5x +8 -5x + 8 = 2y=-5x+8

2y/2=-5x/2+8/2

y=-5/2x+4

Z^5=-7776i

Sloan [31]

Answer:

Z=+6

Step-by-step explanation:

Z^5=-7776i

Let's note that i I mathematics means negative one i.e

i = -1

So the equation is equal to

Z^5=-*-(7776)

Z^5 = 7776

Z= 5√7776

Since it's a divisible by 6

It's giving us a clue that 6 it's the answer.

Ok let's check the 5th root of 7776 in our calculator.

Z=+6

+6 is the solution to the equation

Z^5=-7776i

Find the value of x. A) 21 B) 27 C) 31 D) 34

Ivahew [28]

The 2 angles given are vertical angles, which mean they are the same.

So we have: 3x +1 = 64

Subtract 1 from each side:

3x = 63

Divide both sides by 3:

X = 63 / 3

X = 21

The answer is A.
