How would I show 2/5 as a division problem? Please explain using complete sentences.

1 answer:

3 0

If you mean to ask how you divide 2 by 5, then consider instead dividing 20 by 5, then divide that result by 10 (which is as simple as moving a decimal point to the left)

We have 20/5 = 4, then 4/10 = 0.4.

Why does this work? All we're doing is multiplying by 1 in the form of 10/10, then moving around factors within the product:

2/5 = 2/5 * 10/10 = (2*10)/5 * 1/10 = 20/5 * 1/10 = 4/10 = 0.4

Suppose z is proportional to the square root of x. If z = 717 when x = 9, find the proportionality constant k.??

Dahasolnce [82]

Answer:

239

Step-by-step explanation:

Write the equation. Fill in the given values, and solve for the unknown,

z = k√x

717 = k√9

k = 717/3 = 239

The constant of proportionality is 239.

Point A is located at (−2, −6), and D is located at (−6, 8). Find the coordinates of the point that lies halfway between A and D

Afina-wow [57]

Answer:

(-4,1)

Step-by-step explanation:

Point A is located at (−2, −6), and D is located at (−6, 8).

We need to find the midpoint of A and D

Mid point formula is $(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Point A is (-2,-6) that is (x1,y1)

Point D is (-6,8) that is (x2, y2)

plug in the values in the formula

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

$(\frac{-2-6}{2}, \frac{-6+8}{2})$

$(\frac{-8}{2}, \frac{2}{2})$

Mid point is (-4, 1)
