The required x- and y- coordinates of point e, which partitions the directed line segment is (17, 11)

<h3>Midpoint of coordinates</h3>

The middle point of two coordinates is known as its midpoint. The formula for calculating the midpoint of a coordinate is expressed as:

$m(x,y)=(\frac{mx_1+nx_2}{m+n}, \frac{my_1+ny_2}{m+n})$

Given the coordinate points J(-15, -5) and k(25, 15) partitioned in the ratio 1:4, the x- and y- coordinates of point e, which partitions the directed line segment is given as:

$m(x,y)=(\frac{1(-15)+4(25)}{1+4}, \frac{1(-5)+4(15)}{1+4})\\m(x,y)=(\frac{85}{5}, \frac{55}{5} )\\m(x, y) = (17,11)$

Hence the required x- and y- coordinates of point e, which partitions the directed line segment is (17, 11)

Sum of the areas of two squares is 468 m2. If the difference of their perimeters is 24m, determine the sides of the two sqares.

postnew [5]

Answer:

Step-by-step explanation:

square = 468 m² x² + (6+x)² = 468 [Area of a square = side²] x² + (6)² + x² + 2×6×x= 468 [(a+b)²= a²+b²+2ab] 2x² + 36 + 12x= 468 2x² + 12x + 36 - 468= 0 2x² + 12x + 36 - 432 = 0 2(x² +6x - 216)= 0 x² +6x - 216 = 0 x² +18x -12x -216 =0

mayflies can live at the bottom of lakes for 2 to 3 years before they become winged adults.Mayflies are between 4/10 inches and

Airida [17]

To simplify any fraction, look for a common factor in the top number
and the bottom number. If you find one, divide the top and bottom
both by their common factor. Eventually, you reach the point where
their only common factor is ' 1 ' ... that's when it's in simplest form.

4 and 10 both have 2 as a factor.

When you divide top and bottom both by 2, you have 2/5 .
This is the simplest form of 4/10 .

None of this has anything to do with mayflies. You can use the same
process to simplify fractions in ANY situation where fractions arise.
