In the diagram, AB is divided into equal parts. The coordinates of point A are _____, and the coordinates of point I are______ .

tankabanditka [31]

Answer:

The coordinates of point A are (-10,-4). The coordinates of I are (-3.875,-10.125).

Step-by-step explanation:

It is given that the the line AB is divided into equal parts. Therefor distance between two consecutive points are equal.

The point D is mid point of A and F.

$(x,y)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

$(-8.25,-5.75)=(\frac{x+(-6.5)}{2},\frac{y+(-7.5)}{2})$

$-8.25=\frac{x-6.5}{2}$

$-16.50=x-6.5$

$-10=x$

$-5.75=\frac{y-7.5}{2}$

$-11.50=y-7.5$

$-4=y$

Therefore the coordinates of A are (-10,-4).

Similarly the pint H is midpoint of F and B.

$(-4.75,-9.25)=(\frac{x+(-6.5)}{2},\frac{y+(-7.5)}{2})$

The values of x and y are,

$x=-3$

$y=-11$

Therefore the coordinates of B are (-3,-11).

The point I is mid point of HB. H(-4.75,-9.25) and B(-3,-11).

$(x,y)=(\frac{-4.75-3}{2},\frac{-9.25-11}{2})$

$(x,y)=(-3.875,-10.125)$

Therefore the coordinates of I are (-3.875,-10.125).

Billie bikes 9 miles in 45 minutes. Which rates are equivalent to 9 miles in 45 minutes? Select all that app

Whitepunk [10]

The equivalent rate to 9 miles in 45 minutes is C. 13.5 miles in 67.5 minutes

<h3>How to calculate the value?</h3>

From the information, Billie bikes 9 miles in 45 minutes. It should be noted that this is:

9/45 = 1/5

Therefore, the equivalent option is:

13.5 miles in 67.5 minutes. It should be noted that when it's divided, it'll be 1/5

Therefore, the correct option is C

The weight distribution of a vehicle specifies that the front wheels carry 55% of the weight. If a certain vehicle weighs 3890 l

mario62 [17]

Answer:

2,139.5 lbs

Step-by-step explanation:

A certain vehicle weighs 3,890 lbs.

The front wheels carry 55% of the weight.

Then,

3,890 lbs - 100%

x lbs - 55%

Write a proportion:

$\dfrac{3,890}{x}=\dfrac{100}{55}$

Cross multiply:

$100x=55\cdot 3,890$

$100x=213,950\\ \\x=2,139.5$
