Conserve Tree Foundation is trying to increase the number of trees in a region that has suffered deforestation. It plants a certain number of trees each year, resulting in a linear growth model, y1 = 5t, where t represents the time that has passed in years and y1 represents the number of trees planted. In the same region, the number of trees remaining, y2, is inversely proportion to the time elapsed, t. This is represented by . The graphs of the two equations are shown.

Answer:

Step-by-step explanation:

The cost that a carpet can cleaning company charges is directly proportional to the number of rooms cleaned. The cost to clean 50 rooms is $1,100.

A.) Write a direct variation equation to represent the cost.

Cost ∝ Number of room

C ∝ N

C = kN

k = Constant of Proportionality

k = C/N

k = 1100/50

k = 220

B.) Using the equation found in part a, how much would it cost a hotel to have 150 rooms cleaned

c = 220 × 150

c = $33000

Cost to clean 150 rooms = $33,000

Answer:

The probability is 37.5%

Step-by-step explanation:

There are eight total outcomes, but we only need to focus on three. Ang winning a mug and Jack winning either a t-shirt or a mug, that makes three. Write that as a fraction: 3/8, and then divide. 3 divided by 8 gives us 0.375. But we need a percent so multiply that by 100, that now gives us 37.5.

So, the probability that either Ang wins and is given a mug, or Jack wins is 37.5%. If it makes you feel more confident in this, I put the same exact answer for my assessment and I got it correct.

The options that represent solutions to the given inequality are:

The inequality is:

[tex]y > 2 + 9x[/tex]

Item a:

x = 7, hence, the solution is:

[tex]y > 2 + 9(7)[/tex]

[tex]y > 67[/tex]

67 > 65, hence it is a solution.

Item b:

x = 8, hence, the solution is:

[tex]y > 2 + 9(8)[/tex]

[tex]y > 74[/tex]

74 = 74, hence it is not a solution.

Item c:

x = 5, hence, the solution is:

[tex]y > 2 + 9(5)[/tex]

[tex]y > 47[/tex]

49 > 47, hence it is a solution.

Item d:

Answer:

11

Step-by-step explanation:

n+1=4(n-8)

n+1=4n-32

4n-n-32=1

3n-32=1

3n=1+32

3n=33

n=33/3

n=11

Answer:

n = 11

Step-by-step explanation:

The equation is n+1=4(n-8). This is much easier to solve after expanding, which makes n+1=4n-32. Then, add 33 to each side to make n+33=4n. Next, take away n from each side, to get 33=3n. You want to find n, so divide each side by 3. This means you end up with 11=n.

Answer:

  y +2 = -1/2(x -7)

Step-by-step explanation:

The line PQ has a rise of 6 units for a run of 3 units, so its slope is ...

  m = rise/run = 6/3 = 2

A line perpendicular to PQ will have a slope that is the opposite reciprocal of that, so ...

  -1/m = -1/2

We have the slope of the desired line, and a point it needs to pass through, so we can use the point-slope form of the equation of a line.

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

An equation for the desired line is ...

  y +2 = -1/2(x -7)

This can be rearranged to other forms.

  y = -1/2x +3/2 . . . . . slope-intercept form

  x +2y = 3 . . . . . . . . . standard form

Answer: 0.614

Step-by-step explanation:

First find the probability that he catches the bus in a day.

Probability of catching bus once = 1 - Probability of missing bus

= 1 - 0.15

= 0.85

If he arrives on 3 consecutive days at 7:30 am, the probability he will catch the bus is:

= (P | Day 1) * (P | Day 2) * (P | Day 3)

= 0.85 * 0.85 * 0.85

= 0.614

The approximate probability that he catches the bus all  three days is 0.614.

Given that,

Forrest has determined that if he gets to the bus stop at 7:30 am, there is a 0.15 probability that he misses the bus.

If  he arrives at the bus stop three consecutive days at 7:30,

We have to determine,

What is the approximate probability that he catches the bus all  three days.

According to the question,

The probability that he catches the bus in a day.

Probability of catching bus once = 1 - Probability of missing bus,

= 1 - 0.15

= 0.85

If he arrives on 3 consecutive days at 7:30 am,

Then, the probability he will catch the bus is:

= (P | Day 1) × (P | Day 2) × (P | Day 3)

= 0.85 × 0.85 × 0.85

= 0.614

Hence, The approximate probability that he catches the bus all  three days is 0.614.

Answer:

-15 5/6

Step-by-step explanation:

Combine the given terms (through addition and subtraction).

14 7/8  -  15  -  5/6  -  14 7/8

Identify the LCD:  It is 24

Therefore we have:

14 21/24 - 15 - 20/24 - 14 21/24

Combining the whole numbers, we get

14 - 15 - 14, or -15

and combining the fractions, we get

21 - 20 - 21

----------------- = -20/24

       24

and so we have -15 - 20/24, or -15 - 5/6, or -15 5/6

option A is correct answer of this qn

The word which best describes XV is Angle Bisector.

A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.

Sum of the interior angles of a triangle is 180 degrees.

Given is a triangle XYZ.

Here a line segment is drawn from the vertex X to the opposite side YZ.

Median is the line segment joining the vertex of a triangle to the mid point of the opposite side.

Here, it is not given that, YV = ZV, so it is not median.

Altitude is the perpendicular line joining the vertex to the opposite side.

Here, it is not given the line is perpendicular. so it is not altitude.

Perpendicular bisector is a line that bisects the opposite line in to right angles. It is also not given.

Angle bisector is a line which divide the angle from which the line is drawn. here it is given that both angles equal to 40°.

So the line is angle bisector.

Hence the correct option is Angel Bisector.
