A fish population that started at 250 has begun to decrease by 12 percent each week. Which equation below could be used to model this situation?

P=250(0.12)x

B
P=250(0.88)x

C
P=12(250)x

D
P=−250(0.12)x

Answers

Answer 1

250 - 250 * 12% = 250 * (1 - 12%) = 250 * 0,88

with x = fish number

=> P = 250 * 0,88 * x

Answer 2

Answer: A. P=250(0.12)x

Step-by-step explanation:

12%= 0.12

250 x 0.12 = the amount decreased by each week

Which of the following is the square of a binomial?
A)m^2-mn+n^2
B)c^2-2cd+d^2
C)16x^2 + 9y^2
D)a^2+b^2

Answers

Answer: Choice B

c^2-2cd+d^2 = (c-d)^2

We can verify this with the following steps

(c-d)^2 = (c-d)(c-d)

(c-d)^2 = c(c-d) - d(c-d)

(c-d)^2 = c^2-cd-cd+d^2

(c-d)^2 = c^2-2cd+d^2

B. y - 17= 1/4(x + 164)
C. y + 164= 1/4(x - 17)
D. y - 164= 1/4(x + 17)

Answers

I really think it’s c or d not to sure but it’s definitely not a sorry.but good luck

The Equation of line is  y + 17= 1/4(x - 164).

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

X= 164, -8, 4, 164

Y= -99, -60, -57, -17

Using slope

= ( -17 + 57 )/ ( 164 - 4)

=  40/ (160)

=  1/4

So, Slope- intercept form

y + 17 = /4 ( x- 164)

Angles 1 and 2 are a supplementary pair with the measure of angle 2 being six more than twice the measure of angle 1. What is the measure of angle 2?

Answers

Answer:

58° and 122°

Step-by-step explanation:

Let the 1st angle be 'a'.

2nd angle = 6 more than twice of a = 2a + 6.

Supplementary angles add upto 180°.

=> a + (2a + 6) = 180

=> a + 2a + 6 = 180

=> 3a + 6 = 180

=> 3a = 174

=> a= 174/3 = 58

Thus, angles are:

a = 58°.

2a + 6 = 2(58°) + 6 = 122°

Which is greater: 3x3/2 or 3X2/3 Why?

Answers

Answer:

3X3/2 is greater

Step-by-step explanation:

Go left to right and solve the equations.

Equation 1: 3 multiplied by 3 is 9. 9 divided by 2 is 4.5

Equation 2: 3 multiplied by 2 is 6. 6 divided by 3 is 2

Equation 1 yields a greater value.

Answer:

The 3x3/2 is greater than 3x2/3

Step-by-step explanation:

Here is a simple tip when solving these questions:

Decimal form is always great to use because you get the answer instantly instead of finding a common denominator while involving fractions.

Let's solve 3x3/2.

First, do 3x3 which is 9.

Your problem should be 9/2

Now, you could do this as a mixed number but like I said there shall be more work so you should do 9/2 on a calculator or divide but involve decimal point if you have a remainder.

9 divided by 2 is 4.5

9/2 is 4.5 (Above is the interpretation in words)

Next, do 3x2/3

The same thing as last, do 3x2 first.

Your problem should be 6/3  

If we know our division facts then 6 divided by 3 is 2.

Lastly, compare our numbers.

The 3x3/2 is 4.5 and the 3x2/3 is 2
Line the numbers up:

4.5

2.0

The tens digit clearly shows that 4 is greater than 2.

Therefore,

The 3x3/2 is greater than 3x2/3
