The coordinates of the other vertices of the triangle are (2a, 0), (2a, b), and (a, b).

What are the coordinates of the vertices of the triangle?

The coordinates of the vertices of a triangle are (x1,y1), (x2,y2), and (x3,y3). The line joining the first two is divided in the ratio l:k and the line joining this point of division to the opposite angular point is then divided in the ratio m:k+l.

To find the coordinates of the other vertices of the triangle, you can use the fact that the midpoint of a line segment is located at the average of the coordinates of the endpoints of the segment.

If the midpoint of one side of the triangle is located at (a, 0), then the coordinates of the two endpoints of this side must be (a, 0) and (2a, 0). The coordinates of one of the vertices is (2a, 0), and since this vertex is not the one located at the origin, the coordinates of the other vertex must be the origin, or (0, 0).

If the midpoint of another side of the triangle is located at (2a, b), then the coordinates of the two endpoints of this side must be (2a, b) and (2a, 0). One of the endpoints is (2a, 0), which we already know is a vertex of the triangle. The other endpoint, (2a, b), is also a vertex of the triangle.

Finally, if the midpoint of the third side of the triangle is located at (a, b), then the coordinates of the two endpoints of this side must be (a, b) and (0, 0). One of the endpoints is (0, 0), which we already know is a vertex of the triangle. The other endpoint, (a, b), is also a vertex of the triangle.

Hence, the coordinates of the other vertices of the triangle are (2a, 0), (2a, b), and (a, b).

Eddie and Brad together shovel the snow in 1 hour 26 minutes.

Two or more expressions with an Equal sign is called as Equation.

Given that it takes Eddie 2 hours to shovel the snow from a driveway and sidewalk.

Brad can shovel the snow from the same driveway and sidewalk in 5 hours.

We now find how long would it take them working together to shovel the snow.

Eddie does 1/2 in 1 hour or x/2 in x hours

Brad does 1/5 in 1 hour or x/5 in x hours

the sum is 1 full job

(x/2)+(x/5)=1

multiply both sides by 10

7x=10

x=(10/7) hours or 600/7 minutes =86 minutes

As we know 1 hour has 60 minutes.

We can write 86 minutes as 1 hour and 26 minutes.

To determine whether Juakali can successfully save the document on the flash disk, you can calculate the total number of words in the document and compare it to the amount of free space on the flash disk.

First, calculate the total number of lines in the document by multiplying the number of pages by the number of lines per page:

Total number of lines = 123 pages * 70 lines/page

= 8610 lines

Next, calculate the number of lines with 14 words by multiplying the total number of lines by the proportion of lines with 14 words:

Number of lines with 14 words = 8610 lines * 36/70

= 4380 lines

Calculate the total number of words in the lines with 14 words by multiplying the number of lines by the number of words per line:

Total number of words in lines with 14 words = 4380 lines * 14 words/line

= 61320 words

Calculate the number of lines with 18 words by subtracting the number of lines with 14 words from the total number of lines:

Number of lines with 18 words = 8610 lines - 4380 lines

= 4230 lines

Calculate the total number of words in the lines with 18 words by multiplying the number of lines by the number of words per line:

Total number of words in lines with 18 words = 4230 lines * 18 words/line

= 76140 words

Finally, add the total number of words in the lines with 14 words and the total number of words in the lines with 18 words to find the total number of words in the document:

Total number of words = 61320 words + 76140 words

= 137,460 words

To determine whether Juakali can successfully save the document on the flash disk, you can compare the total number of words in the document to the amount of free space on the flash disk. Since the flash disk has 256 KB of free space and there are 137,460 words in the document, Juakali will not be able to save the document on the flash disk. This is because the document is larger than the amount of free space available on the flash disk.

The required length of the longest side will be 28/5 cm in the triangle.

The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.

We have been given that the three sides of a triangle are in the ratio of 3:5:7

Let's assume the sides are 3x, 5x, 7x

Since the perimeter of the triangle is 12 cm.

So, 3x+5x+7x = 12

Apply the addition operation,

15x = 12

x = 12/15

Reduce the above fraction to the simplest form

x = 4/5

So, longest side = 7x = 28/5 cm

The new perimeter will be 2 times larger then the old perimeter, if both dimensions of rectangle are doubled.

The length of a shape's outline is its perimeter. You must add the lengths of all four sides of a rectangle or square to determine its perimeter. In this instance, x represents the rectangle's length and y its width.

The figure's length is essentially revealed by the perimeter. Assume that the perimeter of a square with equal sides will be four times that square's sides. The perimeter of a circle, which is determined by its radius, is known as its circumference.

The new dimensions  of rectangle = 4mm and 9mm

The original dimension = 2mm and 4.5 mm

Perimeter of rectangle = P=2(l+w) = 2 (4.5 +2 ) = 13 mm

The pressure of 28 inches of mercury occurs about 6 miles from the eye of the hurricane. We get this from the given algebraic expression.

An expression is formed by variables, constants, and algebraic operations. Since the operation among them is an algebraic or arithmetic operation, it is said to be an algebraic expression.

It is given that the algebraic expression that relates the barometric pressure and the eye of the hurricane as

f(x) = 0.48 ln(x+2) + 27

Here x is the distance in miles from the eye of the hurricane.

f(x) is the pressure of the mercury in a barometer in inches

So, the required distance from the eye of the hurricane when the pressure of 28 inches of mercury in the meter is

(Here f(x) = 28)

f(x) = 0.48 ln(x+2) + 27

⇒ 28 = 0.48 ln(x+2) + 27

⇒ 0.48 ln(x+2) = 28 - 27

⇒ ln (x+2) = 1/0.48

⇒ ln(x+2) = 2.0833

Applying exponential base "e" on both sides, we get

(x+2) = [tex]e^{2.0833}[/tex]

⇒ x + 2 = 8.0309

⇒ x = 8.0309 - 2 = 6.0309

When the result is rounded to the nearest whole number, we get x = 6 miles.

Thus, for the pressure of 28 inches of mercury, the eye of the hurricane is 6 miles far from the barometer.

y = -2/5 x -11/5 is the equation of line with slope -2/5 that passes through the point (2, -3).

The slope of the line is the rise to run ratio, or the rise divided by the run. It expresses the slope of a line in the coordinate plane.

The standard form of an equation is y = mx+c.

Here given,

A line with a slope of -2/5 that passes through the point (2, -3).

Simplify y = mx+c with m=2/5 and (x, y)=(2, -3). That is to say,

-3 = -2/5 (2)+c

⇒ -3 = -4/5 +c

⇒ c = -3 + 4/5

⇒ c = (-15 + 4) / 5

=> c = -11/5

When m = -2/5  and c = -11 /5 are substituted in y = mx+c, we get

y = -2/5 x -11/5
