Benjamin started her walk from the front door of her ground floor apartment. She walked 6 meters to the corner of the building a

notsponge [240]

Answer:

4 meters.

Step-by-step explanation:

Benjamin has walked two legs of a right triangle, so you can connect her two movements with a line if you were sketching the situation.. The displacement is the objects overall change in position in relation to its origin, so in your case, Benjamin's apartment. While the total distance adds up regardless of her position.

So, the total distance Benjamin walked is 10m + 6m = 16m

Her displacement can be found by your best friends, the Pythagorean Theorem: 10m ^2 + 6m ^2 = delta x^2 (or displacement squared).. giving you a displacement of 11.66, or 12 m.

The difference between the distance she walked and her displacement is 4 meters.

leva [86]

Answer:

0.25D^2 π in^2.

Step-by-step explanation:

The cross section is a circle of diameter D inches, so its radius is 0.5D inches.

The area of cross section is πr^2

= (0.5D)^2 π

= 0.25D^2 π in^2.

At the Royal Dragon Chinese restaurant, a slip in the fortune cookies indicates a dollar amount that will be subtracted from yo

Afina-wow [57]

Answer:

We can expect $1.7 off

Step-by-step explanation:

We are given 10 fortune cookies out of which

$1 off = 7 cookies

$2 off = 2 cookies

$6 off = 1 cookie

Probability

A = drawing $1 off cookies P(A) = 7/10

B= drawing $2 off cookies P(B) = 2/10

C= drawing $6 off cookie P(B) = 1/10

Expectation = 1*7/10 + 2*2/10+ 6*1/10

= 7/10 + 4/10 + 6/10

= 17/10 = $1.7 off
