When dividing exponential expressions with similar bases (in the problem, the base is 12), calculate the difference (this means subtract) between their exponents and keep the base:

It is essential that Dr. Gordan searches for an area that is equivalent to 48,000 ft2, and he will look for it.

This is further explained below.

Generally,  As stated in the preceding inquiry, The scale that Dr. Gordan uses

2 in = 100 ft

⇒1 in = 50 ft

A portion measuring 6 inches by 3.2 inches is highlighted by Dr. Gordon.

6 inches of length

= ( 6 × 50 )ft

= 300ft

3.2 inches in width

= ( 3.2 × 50 )

= 160ft

The total area of the section may be calculated as follows:

area = (length x width)

= 300 × 160

= 48,000 ft²

As a result, the needed search area for the portion that Dr. Gordan will conduct is equivalent to 48,000 feet squared.

Answer:

4-0.23=3.77

Step-by-step explanation:

The 60th term of the arithmetic sequence - 29, - 49, - 69 is - 1209.

An ordered collection of objects that allows repetitions is referred to as a sequence.

Consider the arithmetic sequence,

- 29, - 49, - 69

The common difference of the sequence is:

d = - 49 - ( - 29 ) = - 49 + 29 = - 20

The first term of the sequence is a = - 29.

The nth term of an arithmetic sequence  is given as:

aₙ = a + ( n - 1 )d where n is the number of term.

Therefore, the 60th term of the sequence will be:

aₙ = a + ( n - 1 )d

a₆₀ = - 29 + ( 60 - 1 ) × - 20

a₆₀ = - 29 + 59 × - 20

a₆₀ = - 29 + 59 × - 20

a₆₀ = - 29 - 1180

a₆₀ = - 1209

Hence, the 60th term of the arithmetic sequence is - 1209.

The tent cost is equal to 315.

They invested £1500 at the bank with an interest rate of 7%. At the end of 3 years,

So, the principle amount is 1500, rate of interest given by the bank is 7%

and they invested the amount for 3years.

The interest amount can be calculated by using the simple interest formula:

SI = [tex]\frac{PRT }{100}[/tex]

where P denotes the principle amount invested R is the rate of interest and t is the time for which the amount is being invested.

SI = (1500 x 7% x 3)/100

SI = 15 x 21 = 315

The simple interest is calculated to be 315.

They had exactly the right amount saved to buy the tent.

So, the cost of the tent is same as the interest amount. = 315

Therefore, the tent cost is equal to 315.

Given that,

Kathlego, Tessa, and Zane all work two jobs to make ends meet due to the high cost of living, however there are both work in the same field. Doctor, engineer, teacher, lawyer, painter, and writer are among the professions.

As soon as we realize that Zane "is not the doctor," we immediately rule off that possibility and move on to the other professions.

Given that "Zane beat Tessa and the painter at tennis," we can infer that Tessa and the painter are no longer together, which makes Kathlego the Painter.

We currently have.

Kathlego is an painter.

We can now go on to "The painter was engaged by the doctor to do the task." The fact that Zane is not the doctor and we know the painter is Kathlego gives us a huge hint. Tessa is therefore unquestionably a doctor.

We currently have:

A painter, Kathlego.

Tessa is a engineer.

We may now infer that the person is one and the same because we have "The teacher and the writer went fishing with Kathlego." We can rule out Kathlego and Tessa as the teacher and writer because they each have two jobs. Thus, we are left to assume that Zane is the instructor and author.

We currently have:

Tessa is a engineer.

Both a writer and a teacher, Zane.

Consequently, the lawyer, Kathlego, is the last task left for us to complete.

Answer:

Step-by-step explanation:

Applying the definition of perpendicular bisector, the value of x is: 10.

A perpendicular bisector can be defined as any line segment that bisects another line segment. That is, it divides another line segment into two equal parts having the same length.

Since AD is the perpendicular bisector of BD, then, BD = DC.

BD = 5x - 10

DC = 3x + 10

Substitute

5x - 10 = 3x + 10

Combine like terms

5x - 10 + 10 = 3x + 10 + 10 [addition property of equality]

5x = 3x + 20

5x - 3x = 3x + 20 - 3x [subtraction property of equality]

2x = 20

Divide both sides by 2

2x/2 = 20/2 [division property of equality]

x = 10

The value of x is 10.

Answer:

C

Step-by-step explanation:

The y-axis is the vertical axis, which is represented by y, and the x-axis the horizontal axis, represented by x. You can see in the graph that (3, 12) is one point. 3 x 4 = 12, where x is 3 and y is 12. This proves the proportional relationship with x and y is y = 4x. To double check, you can plug in (3, 12) to get 12 = 4(3). 4 x 3 = 12, so Option C shows the proportional relationship.

We typically write linear equations in slope-intercept form:

[tex]y=mx+b[/tex]

Because this graph has a proportional relationship, it means that they pass through the point (0,0), and that our y-intercept is 0. Our equation looks like this:

[tex]y=mx[/tex]

First, we typically find the slope of the equation using the slope formula:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex] where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points that fall on the line

⇒ Plug in any two points that the line passes through, such as (0,0) and (3,12):

[tex]m=\dfrac{12-0}{3-0}\\\\m=\dfrac{12}{3}\\\\m=4[/tex]

Therefore, the slope of the line is 4. Plug this into [tex]y=mx[/tex]:

[tex]y=4x[/tex]

By finding the x-intercepts of the two linear functions, we can see that the laptop can stay on for 5 hours and the tablet for 6 hours, so the tablet can stay on for longer.

We know that g(x) shows the percent of battery power on a laptop, and on the graph we can see that it becomes zero at x = 5 hours, so the laptop can stay on for 5 hours.

We also know that linear function f(x) shows the battery of a tablet, the function is:

f(x) = 0.75 - 0.125*x

The value will be zero when the tablet runs out of battery, so we can solve:

0 = 0.75 - 0.125*x

0.125*x = 0.75

x = 0.75/0.125= 6

So the tablet can stay on for 6 hours, we conclude that the tablet can stay on longer.
