we know that

If the point has an nonzero abscissa (x coordinate) then it can be located in any of the four quadrants

If the point has an negative ordinate (y coordinate) then it can be located in Quadrant III or Quadrant IV

therefore

the answer is the option

Quadrant III or Quadrant IV

HELP I REALLY NEED HELP

Answer: 72 inches squared

Step-by-step explanation:

So, the real floor of a classroom is 36 feet by 32 feet.

And the scale drawing, has length of the classroom equal to 9 inches.

What is the area in square inches of the floor in the scale drawing

1 foot = 12 inches

The length of the classroom, measured in feet, has been multiplied by 12, to get converted in inches. After that, it has been divided by a number, a proportion, to get to 9 inches.

36feet * 12 / x = 9 inches

432 inches / x = 9 inches

Now, to solve for x, we can cross-multiply

432 inches = 9x inches

Divide 9 inches on both sides.

x = 48

To solve the exercise, we need to calculate the floor's area in the scale drawing.

We have the length = 9 inches.

Now, let's calculate the width

Width = 32 feet * 12 / 48

Width = 384 inches / 48

Width = 8 inches

Area = Length * Width

Area = 9 inches * 8 inches

Area = 72 inches squared

Hope I helped!

A spinner has 20 equally sized sections, 8 of which are yellow and 12 of which are blue. The spinner is spun and, at the same ti

Lyrx [107]

Answer:

3/10.

Step-by-step explanation:

Probability (A blue on the spinner) = 12/20 = 3/5.

Probability( tails) = 1/2.

The probability of a blue and tails = 3/5 * 1/2

= 3/10.

The area of a rectangular tennis court is 140 square meters. It’s length is 6 meters less than twice it’s width. Find the dimens

lina2011 [118]

Let the width be : x
length : (2x - 6)

(2x - 6) (x) = 2x square - 6x

2x square - 6x = 140
2x square - 6x - 140 = 0

if you use the cross method or calculator you’ll get :

( x - 10 ) ( x + 7) = 0

x = 10 or x = -7 ( reject because negative )
so we use x = 10.

width = 10
length = 2(10) - 6 = 14

On Novermber 27, 1993, the New York times reported that wildlife biologists have found a direct ink between the increase in the

Korolek [52]

Answer:

a. 1 263 888

b. 130 701

c. 72 years

Step-by-step explanation:

a. The differential equation applies here.

Let the quantity increase for a certain time be given by Q(t)

Every unity of time, the quantity increases by $1+\frac{r}{100}$ so that after the time t, the quantity remaining will be given by:

$Q(t) = (1+ \frac{r}{100} )^{t}$

In a similar manner, the quantity R(t) decreases at a rate given by the following expression:

$1-\frac{r}{100}$ and after the time , t the quantity of R remaining will be given by:

$R(t) = (1-\frac{r}{100} )^{t}$

a. To find the population of humans in 1953

$Q(t) = (1+ \frac{r}{100} )^{t}$

1993 - 1953 = 40 years = t

Q(40) = Q× $1.06^{40}$

Q = 1 263 888.44

≈ 1 263 888

b. For bear population in 1993:

$R(t) = (1-\frac{r}{100} )^{t}$

t = 40

R(40) = $b 0.94^{40} = 11 000$

b = 130 700. 889

≈130 701

c. time taken for black bear population number less than 100 is given by:

130 = 11000× $0.94^{t}$

solving using natural logarithms gives t = 72.72666
