Use repeated subtraction to divide.1÷1/5

Mekhanik [1.2K]

1 - 1/5 = 5/5 - 1/5 = 4/5

4/5 - 1/5 = 3/5

3/5 - 1/5 = 2/5

2/5 - 1/5 = 1/5

1/5 - 1/5 = 0

We can subtract 1/5 from 1 a total of 5 times, so 1 ÷ 1/5 = 5.

A food pantry distributes 10-ounce bags of flour. A supermarket donates nine 5-pound bags to the pantry. How many 10-ounce bags

DanielleElmas [232]

Given:
nine 5 pound bags
distributed into 10-ounce bags

1 pound = 16 ounces

9 x 5 pounds = 45 pounds

45 pounds * 16 ounces/lbs = 45 * 16 oz = 720 ounces

720 ounces / 10 ounce bags = 720/10 = 72 bags.

The workers at the food pantry will be able to make 72 bags.

The scores on the entrance exam at a well-known, exclusive law school are normally distributed with a mean score of 200 and a st

ruslelena [56]

Answer:

the lowest passing score would be x = 298

Step-by-step explanation:

School wishes that only 2.5 percent of students taking test pass

We are given

mean= 200,

standard deviation = 50

We need to find x

The area under the curve can be found by:

2.5 % = 0.025

So, 1- 0.025 = 0.975

We need to find the value of z for which the answer is 0.975

Looking at the z-score table, the value of z is: 1.96

Now, using the formula:

z = x - mean/standard deviation

1.96 = x - 200/50

=> 1.96 * 50 = x-200

98 = x - 200

=> x = 200+98

x = 298

So, the lowest passing score would be x = 298

Eva8 [605]

Answer:

it will take 3 yrs for the value of camera to reach $162.

Step-by-step explanation:

Pd = P(1-R/100)^T

162 = 384(1-25/100)^T

162/384 = (3/4)^T

27/64 = (3/4)^T

(3/4)^3 = (3/4)^T

T = 3
