With the ratio at 1:1, Point C appears to be the midpoint. Use the midpoint formula to ascertain (make sure of) whether Point C

Mila [183]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete because the coordinates of A, B and C were not given in the question.

However, the following explanation will guide you...

The midpoints, C of two point A and B is calculated as:

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

Where $(x_1, y_1)$ are the coordinates of A

and

$(x_2,y_2)$ are the coordinates of B

Take for instance, the given coordinates are

A(4,6); B(2,4) and C(3,5)

Then;

Plug in these values in the given formula:

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

$(3,5) = (\frac{4 + 2}{2}, \frac{6 + 4}{2})$

$(3,5) = (\frac{6}{2}, \frac{10}{2})$

$(3,5) = (3,5)$

In that case,

C is really the midpoint

To the b part: <em>Explaining why ratio 1:1 is used</em>

The reason is that both parts of the ratio are in equal proportion (1 and 1);

Because of this equal proportion, ration 1:1 is right to calculate the midpoint

Mick can drive his car 33 miles with one gallon of gas. how much gas does he need to drive 15,000 miles (his annual mileage)?

Troyanec [42]

Answer: (pt 1) 454.5 gallons. (pt 2) $1,390.77

Step-by-step explanation:

PART ONE:

$\frac{33}{1} = \frac{15,000}{x}$

33 · x = 15,000 · 1

33x = 15,000

x = $\frac{15,000}{33}$

x = 454.5 (rounded)

PART TWO:

454.5 · 3.06 = 1,390.77
