Answer:

... 0.7 . . . or 0.67 . . . or 0.667 . . . or 0.6667 . . . or ...

Step-by-step explanation:

2/3 is a repeating decimal: 0.66666... Round where you like. The rounding is usually in the 2nd or 3rd decimal place, depending on the accuracy needed.

... 0.67 or 0.667 . . . . . the decimal fraction of dogs

_____

<em>Comment on wording</em>

The question asks for the "number of dogs". In the problem statement, we're told that number is 2 (out of 3). Actually, it can be any even integer number (out of 3/2 that many), up to 2/3 of the total dog population (which is estimated at over 520 million).

Had the problem asked for <em>the fraction of dogs</em>, then an appropriate answer is 0.67.

What is the slope of the line whose equation is 2x-6y=0?
Lina20 [59]
Equation of a line is:

y=mx+C

------------------------

We're looking for m as m stands for gradient.

2x-6y=0 (Divide all terms by 2)

x-3y=0

3y=x

y=1/3x

y=1/3x+0

Therefore m=1/3, C=0.

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
storchak [24]

Answer:

a_n = 1200(1.35)^n

Step-by-step explanation:

Equation to remember:

P_0(1+r)^t where t = time

P_0 = 1200 since that's the initial population

r  = .35 rate of change \\

t  = 5 years

Plug in the numbers;


a_5 = 1200(1+.35)^5


Since the prompt looks like it's asking for an equation given any number of years.. then just change 5 to n for number of years.


a_n = 1200(1.35)^n

What is the height of an equilateral triangle with side lengths of 15? round to tenths?
Vinil7 [7]
If this is an equilateral triangle, we need half of it to find the height which is a leg of a right triangle with a hypotenuse of 15.  That means that the base of this half triangle is 7.5.  Use Pythagorean's Theorem to fine the height.  x^{2} =(15) ^{2} -(7.5) ^{2}.  x = 12.99 or 13

The coordinate plane below represents a city. Points A through F are schools in the city. graph of coordinate plane. Point A is
Firlakuza [10]
Part A;
There are many system of inequalities that can be created such that only contain points C and F in the overlapping shaded regions.

Any system of inequalities which is satisfied by (2, 2) and (3, 4) but is not stisfied by <span>(-3, -4), (-4, 3), (1, -2) and (5, -4) can serve.

An example of such system of equation is
x > 0
y > 0
The system of equation above represent all the points in the first quadrant of the coordinate system.
The area above the x-axis and to the right of the y-axis is shaded.



Part 2:
It can be verified that points C and F are solutions to the system of inequalities above by substituting the coordinates of points C and F into the system of equations and see whether they are true.

Substituting C(2, 2) into the system we have:
2 > 0
2 > 0
as can be seen the two inequalities above are true, hence point C is a solution to the set of inequalities.


Part C:
Given that </span><span>Natalie can only attend a school in her designated zone and that Natalie's zone is defined by y < −2x + 2.

To identify the schools that Natalie is allowed to attend, we substitute the coordinates of the points A to F into the inequality defining Natalie's zone.

For point A(-3, -4): -4 < -2(-3) + 2; -4 < 6 + 2; -4 < 8 which is true

For point B(-4, 3): 3 < -2(-4) + 2; 3 < 8 + 2; 3 < 10 which is true

For point C(2, 2): 2 < -2(2) + 2; 2 < -4 + 2; 2 < -2 which is false

For point D(1, -2): -2 < -2(1) + 2; -2 < -2 + 2; -2 < 0 which is true

For point E(5, -4): -4 < -2(5) + 2; -4 < -10 + 2; -4 < -8 which is false

For point F(3, 4): 4 < -2(3) + 2; 4 < -6 + 2; 4 < -4 which is false

Therefore, the schools that Natalie is allowed to attend are the schools at point A, B and D.
