Consider a city whose streets are laid out as a grid. Streets run north-south or east-west. A visitor is dropped off by a cab at

Ann [662]

Answer:

84 possible paths

Step-by-step explanation:

Given

$N =3$ --- 3 blocks north

$E = 6$ --- 6 blocks east

Required

Number of distinct path

To solve this question, we make use of the following formula

$^{m+n}C_n \ =\ ^{m+n}C_m$

The above formula implies that;

On a single path, there is a total of m + n steps to get to a particular position, where each path is either in m direction or n direction.

In this case:

$m = 3$

$n = 6$

So, we have:

$^{m + n}C_n = ^{3+6}C_6$

$^{m + n}C_n = ^9C_6$

Apply combination formula

$^{m + n}C_n = \frac{9!}{(9-6)!6!}$

$^{m + n}C_n = \frac{9!}{3!*6!}$

Expand the numerator

$^{m + n}C_n = \frac{9*8*7*6!}{3!*6!}$

$^{m + n}C_n = \frac{9*8*7}{3!}$

Expand the denominator

$^{m + n}C_n = \frac{9*8*7}{3*2*1}$

$^{m + n}C_n = \frac{504}{6}$

$^{m + n}C_n = 84$

Hence, there are 84 possible paths

$^{m + n}C_m$ will also give the same result

40% of the calories in a bag of chips come from fat. If 100 calories come from fat, how many calories does the whole bag of chip

ANTONII [103]

Answer:

this might help

Step-by-step explanation:

1) Fat:

a. Multiply the grams of fat by 9* = (x) the number of fat calories. b. Divide (x) the number of fat calories by the total number of calories in the food

item = % fat content. * 1 gram of fat contains 9 calories (kcal)

2) Saturated Fat:

a. Multiply the grams of saturated fat by 9 = (xx) the number of saturated fat

calories in the food item. b. Divide (xx) the number of saturated fat calories in the food item by the total

number of calories in the food item = % of saturated fat.

3) Sugar:

a. Divide the number of grams of sugar by the total weight of the food in grams = %

of sugar. (Total sugar)
