Using proportions, the coordinates of point P that divides the directed line segment YX in the given ratio are found according to the following rule:

P - X = 3/8(Y - X).

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the context of the problem relating the variables.

One example of application is for the coordinates of a point dividing a segment, as the distance between one end point and the dividing point is a fraction of the total length of the segment.

In the context of this problem, we have that point P divides segment XY in a 3:5 ratio, meaning that PX is 3/8 of the total distance y/x, hence the following proportional equation is built:

P - X = 3/8(Y - X).

In which:

This equation is used to find both the x-coordinate and the y-coordinate of P, as follows:

Equivalent ratios are the ratios that are the same when we compare them. Three equivalent ratios are 1/2, 4/8, 3/6 in digits from 1 to 9.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other

Equivalent ratios are the ratios that are the same when we compare them.

The digits from 1 to 9 include 1,2,3,4,5,6,7,8,9.

Ratios are nothing but fractions.

Let 1/2 (one by two) is the first ratio.

Now 3/6 (three by six) is the second ratio

4/8 (four by eight) is the third ratio.

If we calculate the value of 1/2 = 0.5

The value of  3/6=1/2=0.5

The value of 4/8= 1/2=0.5

we get the same answer for all the ratios 1/2, 4/8 and 3/6 that is 0.5

That is 0.5 or 1/2.

Hence the three equivalent ratios are 1/2, 4/8, 3/6.

The sunflower had a height of 13 inches on day 0 and 13.91 inches on day 1.

Because sunflowers are big feeders and require a slightly alkaline soil (pH 6.0 to 7.5), make sure we put them in nutrient-rich soil. Before planting, we should also make sure the soil is weed-free. Since a sunflower is cultivated in a garden, its height grows by 7% every day. The sunflower is 15.7 inches tall 2.79 days after being planted. To get the sunflower's 1-day growth factor, apply the following calculation:

X x (1 + 0.07) ^ 2.79 = 15.7

X x 1.07 ^ 2.79 = 15.7

1.2077X = 15.7

X = 15.7 / 1.2077

X = 13

13 x 1.07 = 13.91

The sunflower therefore measured 13 inches on day 0 and 13.91 inches on day 1.

[tex]v = 8( - 8) \\ v = -6 4[/tex]

ATTACHED IS THE SOLUTION

Answer: v/8 - 4 = (-12)

-12 + 4 = (-8)

what divided by 8 is 8?

8/8 = 1 so 8 x 8 = 64

this means v = -64

64/8 - 4 = -12

- 64/8 is -8 and that minus 4 is -12

[tex]|x-4|[/tex] is non-negative, and vanishes when [tex]x=4[/tex].

For a sale of $8400 made his gross pay is $373.21

In this question, we have been given Mike Lasueze is guaranteed a minimum salary of $220 per week or 5.5 percent of his total sales, whichever is greater.

We need to find his gross pay for a week in which his total sales were $8,400

weekly pay = $220

commission = 5.5% of sales

                    = 0.055 of sales

let m be the total sale and his gross pay be represented by y

So, we get an equation for the total/gross pay:

y = 0.055x + 220

Required is the gross pay y for x = 8400

y = 0.055(8400) + 220

y = 682

Therefore, for a sale of $8400 made his gross pay is $373.21

Step-by-step explanation:

the area of the parallelogram is

baseline × height.

we know the baseline (15 cm), because as parallelogram it must have 2 pays off equal sides. so, the bottom side must be 15 cm too.

15×height = 390

height = 390/15 = 26 cm

now, the height of the triangle on the right is the same height.

and the baseline of this triangle is 25 - 15 = 10 cm.

the area of a triangle is

baseline × height / 2

so, in our case

10 × 26 / 2 = 10×13 = 130 cm²

therefore the area of the trapezium is the area of the parallelogram plus the area of the triangle :

390 + 130 = 520 cm²

The total weight is 57kg

The perimeter = 2×(8+6)

The diagonal = √8²+6²

100 = 10m

The total length of the frame =

Therefore the total Weight =

38× 1.5 kg = 57 kg

What is the formula for weight?

The force of gravity acting on an item is known as its weight, and it can be determined using the formula w = mg, which equals the mass times the acceleration of gravity.

You must multiply the sectional area, length, and density collectively to determine the weight of your metal. The product must then be divided by 1,000 in order to convert the weight to kilograms.

The price of the jacket in decimals is $ 41.89

The decimal numeral system is widely used to express both integer and non-integer numbers.

Let the price of the jacket be x.

Price of the pair of shoes = x + 7.65

Total cost of both the pieces = x + x + 7.65 = 2x+7.65

But the total cost is $91.43

Hence forming a linear equation we get :

$91.43= 2x+7.65
