How high is a tree that casts a 24 ft shadow at the same time a 5-ft pole casts a shadow 14 ft-long the tree height

The two representations are:

x > 5

A number line with an open circle at 5 and a line that points to the right.

We start with the inequality:

-3(2x - 5) < 5*(2 - x)

First, we need to solve this for x, expanding both sides we get:

-6x + 15 < 10 - 5x

Now we move the terms with x to the right side and the terms without to the left side.

15 - 10 < 6x - 5x

5 < x

This is a representation of the inequality.

The other will be a graph, to graph this on a number line we need to do an open circle at x = 5, and shade the region to the right (because x is larger than 5).

The point slope form are as follows:

The point slope equation can be represented as follows;

y - y₁ = m(x - x₁)

where

Therefore, (5, 2)(-1, -6)

m = slope = -6 - 2 / -1 - 5

m = slope = -8 / - 6

m = slope = 4 / 3

Therefore, using (5, 2) the point slope form is represented as follows;

y - 2 = 4 / 3(x - 5)

using (-1, -6) the point slope form is represented as follows;

y + 6 = 4 / 3(x + 1)

The line which is parallel to the given line y = -2x/3 + 1 is 2x+3y=-18, there slopes are equal

Given data

line y = -2x/3 + 1

The equation of a line is represented as y = mx + c where m represents the slope. The unique feature of parallel line is that the slopes are equal.

Hence we find the line that has same value of m which is the slope

using the second option: 2x+3y=-18

2x + 3y = -18

3y = -2x - 18

y = -2x/3 - 6

the slope here is m = -2/3 which is equal to the slope of the given equation and hence the correct option

The price of green fabric = $4 and the price of blue fabric is $6.

It should be noted that LaTanya buys 5 yards of blue fabric and 8 yards of green fabric and the blue fabric costs $2 more per yard than the green fabric.

Let the price of the green fabric = x

Price of blue fabric = x + 2

Therefore, the expression will be:

5(x + 2) + 8(x) = 62

5x + 10 + 8x = 62

13x = 62 - 10

13x = 52

Divide

x = 52/13

x = 4

The price of green fabric = $4

The price of blue fabric = $4 + $2 = $6

the rate of change of the linear equation in the table is 120.

Remember that for any linear equation with an slope (also called rate of change) s and it passes through the points (a, b) and (c, d), then the slope can be written as:

s = (d - b)/(c - a)

Using that relation and the first two points on the table (0.5, 60) and (1.5, 180)

We get that the rate of change is:

s = (180 - 60)/(1.5 - 0.5) = 120

So the rate of change is 120.

The actual width of the field 80 yard. when proportion is 3 : 2.

What in mathematics is a proportion?

A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls)

We have the proportion  

                            3/2 = 120/w

where in the numerator are the length and in the denominators the width of the field.

Now ,                        3 . w = 120 . 2

                                  3w = 240

                                    w = 80

Total number of hours both worked last month is; 28.8 hours

Let the number of hours that Herold worked last month be x. Thus, number of hours that Marley worked = 16 + x

Now, we are told that Marley worked 7 hours for every 2 hours that Herold worked. Thus;

(16 + x)/x = 7/2

Cross multiply to get;

2(16 + x) = 7x

32 + 2x = 7x

7x - 2x = 32

x = 32/5

x = 6.4 hours

Step-by-step explanation:

let Irene's share be x and Charlie's share be y

x=2y-8

x+y=$47.50

x=$47.50-y

$47.50-y=2y-$8

$47.50+$8=2y+y

$55.50=3y

y=$55.50/3

y=$18.50

x=$47.50-$18.50

x=$29

Answer:

Irene's share = 29

Charlie's share = 18.5

Step-by-step explanation:

R bill = 47.5

Irene's share = (2 × Charlie's share )-8

Irene's share = y

Charlie's share = x

bill = x + y = 47.5

y = 2x -8

x + 2x - 8 = 47.5

3x = 47.5 + 8= 55.5

x = 18.5

y = 29

The sum to infinity of the terms of this sequence is -36/5

The given parameters are

T3 = -1/6

T6 = -1/1296

The nth term of a geometric sequence is

Tn = a * r^(n-1)

So, we have

T3 = ar^2

T6 = ar^5

Divide both equations

T6/T3 = ar^5/ar^2

Evaluate the quotient

T6/T3 = r^3

Substitute T3 = -1/6 and T6 = -1/1296 in T6/T3 = r^3

(-1/1296)/(-1/6) = r^3

Evaluate the quotient

1/216 = r^3

Take the cube root of both sides

r =1/6

Substitute r =1/6 in T3 = ar^2

T3 = a(1/6)^2

This gives

T3 = a/36

Substitute T3 = -1/6 in T3 = a/36

a/36 = -1/6

This gives

a = -6

The sum to infinity of the terms of this sequence is

S = a/(1 - r)

This gives

S = -6/(1 - 1/6)

This gives

S = -6/(5/6)

Evaluate

S = -36/5

Hence, the sum to infinity of the terms of this sequence is -36/5
