D. x = -6

( 3x-6² - 30x-6 - 72 = 0 )

Step-by-step explanation:

So first you work out:

3x² = ( 3 x -6²) = -108

Then work out 30x = ( 30 x -6 ) = -180

-108 - -180 => 72

Then just do 72 - 72 =

As the angle is greater than 0° and less than 90°, then the angle ABC is acute. (Answer: A)

Herein we find the locations of the three vertices of the figure, of which we must determine the lengths of the two sides of the angle and determine the value of the angle by trigonometry:

BA = 5, BC = 2

θ = tan⁻¹ (BA / BC)

θ = tan⁻¹ (5 / 2)

θ ≈ 68.199°

As the angle is greater than 0° and less than 90°, then the angle ABC is acute. (Answer: A)

The revolution per minutes of the wheels rotation is 912 rev/ min

Given the parameters;

Convert the velocity

[tex]v = 65mph = 65 mil/h - (1609m/mil0/(3600s/h)[/tex]

v = 29. 1 m/s

Let's find the circumference

Circumference = 2 π r

radius = diameter/ 2 = 0. 6096 meters/ 2 = 0. 30 meters

Circumference= 2 × 3. 142 × 0. 30 = 1. 915

Number of revolutions = 29. 1/ 1. 915 = 15.2 rev/ sec

Let's convert to rev/ min

= 15. 2 × 60

= 912 rev/ min

The change in the elevation from the bottom of the Ferris is 21.9 feet.

Elevation change refers to the difference in elevation between the beginning and end of your route.

Given that the distance travelled by Vivian just at bottom of the elevation is -9.6 feet.

The distance traveled by Vivian at the top of the elevation is 12.3 feet.

Vivian's shift in elevation would be expressed as the difference between the elevations at the bottom and top.

Let Ei be the initial elevation of -9.6 feet.

Ef = 12.3 feet as the final elevation

Change in elevation;

ΔE = Ef - Ei

ΔE = 12.3 - (-9.6)

ΔE = 12.3 + 9.6

ΔE = 21.9 feet

Therefore, the change in the elevation is found to be 21.9 feet.

The possible coordinates of point G on this number line are either -10 or 14.

A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numerical values that are placed at equal intervals along its length.

Given the following data:

E = 2.

EG = 12.

On this number line, the coordinate of EG is given by this mathematical expression:

EG = |E - G|

Substituting the given parameters into the expression, we have;

12 = |2 - G|

2 - G = ±12

G = 2 ± 12

Simplifying and evaluating the above expression, we have:

G = 2 + 12

G = 14.

OR

G = 2 - 12

G = -10

Therefore, the possible coordinates of point G on this number line are either -10 or 14.

1. Gardner can put a maximum of 4 flowers in each row

2. At 150 minutes both the student will meet each other

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,

1. For the planting of trees in even rows,

The greatest number of plants he can have in each row to keep the rose bushes and tulips in their own rows,

Taking HCF of number of plants 24 and 28

HCF of 24 and 28 is 4

Thus, Gardner can put a maximum of 4 flowers in each row.

2.

Time taken by the first student to complete one lap is 25 minutes,

So,

1 lap = 25 minute

1 minute = 1 / 25 lap

For the second student,

1 lap = 30 minute

1 minute = 1/30 lap

At time x minute both will meet each other,

Using your answer from part (a), estimate the number of seniors who plan to go to a 4-year college.)

Using complementary and supplementary angles, we have that:

c. The angles are complementary, hence the equation is 4x - 3 + 2x + 1 = 90 and the solution is x = 15.33.

d. The angles are supplementary, hence the equation is 43x + 16 + 110 = 180 and the solution is x = 18.

When the measures of two angles add to 90º, the angles are complementary.

This is the case in item c, hence:

4x - 3 + 2x + 1 = 90

6x = 92

x = 92/6

x = 15.33.

When the measures of two angles add to 180º, the angles are supplementary.

This is the case in item d, hence:

3x + 16 + 110 = 180.
