if three sides of a triangle are in ratio of 3:5:7 and the perimeter of the triangle is 12xm. what is the length of the longest side?
The required length of the longest side will be 28/5 cm in the triangle.
What is the perimeter of a 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
Thus, the required length of the longest side will be 28/5 cm in the triangle.

raphael drives to his office which is 75km away from his house what is his speed if it takes him 1 hour and 15 minutes to get to his office
Answer:
1km\h
Step-by-step explanation:
like in physics, the calculation of speed is total distance divided by total time, you should do the same in math, and so you do 1 hour (60 minutes) + 15 minutes which gives you 75 minutes, and then you divide 75 km by the time so it should look something like this:
[tex]\frac{75 km}{75 minutes}[/tex] which gives you 1
so raphael is going 1 km\h
Answer:

y = -2/5 x -11/5 is the equation of line with slope -2/5 that passes through the point (2, -3).
What is the equation of line?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
As a result, an equation for a line with a slope of -2/5 that passes through the point (2,-3) is y = -2/5 x -11/5.

is 2/5 equivalent to 25
Answer:
2/5 ≠ 25
Step-by-step explanation:
Given question,
→ Is 2/5 equivalent to 25?
Let's check the problem,
→ 2/5 = 25
→ 0.4 ≠ 25
The equivalent fractions of 2/5 are,
→ 2/5 = 4/10
→ 2/5 = 6/15
→ 2/5 = 8/20
→ 2/5 = 10/25
Hence, 2/5 is not equivalent to 25.

ANALYZE PROBLEMS The midpoints of the sides of a triangle are located at (a, 0),(2 a, b) and (a, b). If one vertex is located at the origin, what are the
coordinates of the other vertices?
,( ______0) and (______,______)
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).

Step-by-step explanation:
3) Juakali used Kingo's computer to type a report document which had 123 pages, and
each page occupied by 70 lines. 36 of 70 lines had 14 words while the remaining lines
had 18 words each. He wanted to take the document with him, and he had only a flash
disk with 256 KB as free space. Can he successfully save the document on the device?
Why?
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.
It is important to note that the capacity of a storage device is usually measured in bytes, and 1 KB is equal to 1024 bytes.

The lakefront company should make the investment as in 5 years they'll have a profit of 10000.
What is simple interest?We know simple interest (SI) is given by SI = (p×r×t)/100, where
p = principle, r = rate in percentage, and t = time in years.
Given, the lakefront company is considering investing in a new dock that will cost 560,000.
So, a Capital cost of 10% is (560000/10) = 56000
The company's borrowing rate is 8%.
∴ SI = (560000×8×5)/100.
SI = 5600×8×5.
SI = 224000.
So, The total cost is (560000 + 56000 + 224000) = 840000.
After 5 years they can sell it for 300000.
And has a cash flow of 110000, so in 5 years it is 550000.
So, total earnings is (300000 + 550000) = 850000.

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.
What is an 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.
Calculation: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.
