I got my answer form here: https://web2.0calc.com/questions/my-friend-any-help-is-appreciated

This answer is from CPhill:

At 3 mph....your friend covers  3 / 60   miles per minute

 

At 4 mph......you cover  4/ 60    miles per minute

 

So....every minute....you close    [  4 - 3 ]/ 60   =  1/ 60   miles  on your friend

 

And when she has been walking for 5 minutes......she will be  5 * [3  / 60 ]  = 15/60  = 1/4 of a mile ahead of you when you start 

 

So......the number of minutes, m, it will take to catch your friend can be found by :

 

( 1/60) m  = 1/4      multiply both sides by 60

 

m =  60  / 4   =    15 minutes

I got this answer from here: https://brainly.in/question/18756313

Answer:

144 cm²  

Step-by-step explanation:

Let say Side of original Square

= 4A  cm

Hence Area = (4A)² = 16A²   cm²

Then

Square when folded  in half

Then Sides of rectangle  

will be  4A   &  2A

Now again Folded

Sides can be  2A  & 2A    or  4A  & A

2A  & 2A  would be a Square ( its given that its not a square)

Hence Second Rectangle Sides are 4A & A

Perimeter = 2(4A + A) = 10A

10A = 30cm

=> A = 3 cm

Area  of the original square =   16A²  = 16 * 3² = 144 cm²  

area of the original square = 144 cm²

I got this answer from here: https://web2.0calc.com/questions/compute-the-sum-of-all-positive-integers-k-for-which

 

1984 =  2^6 * 31

 

Just multiply 1984 x 31 =(1, 2, 4, 8, 16, 31, 32, 62, 64, 124, 248, 496, 961, 992, 1922, 1984, 3844, 7688, 15376, 30752, 61504) >>Total = 21 divisors

 

 

31 =3 + 1 =4

I got this answer from https://www.topperlearning.com/answer/the-interior-angles-of-a-polygon-are-in-apif-the-smallest-angle-is-120-degree-and-the-common-difference-is-5-degree-then-the-no-of-sides-in-the-polygo/tk5eo455 so check it out

Smallest angle=120degrees

Common difference=5

A P is 120, 125, 130,……..

The sum of interior angles of a polygon= (n-2)180

Hence Sum of n terms of an A P = (n-2)180

n/2 {2.120+(n-1)5} = 180(n-2)

5n2 -125n +720 = 0

n2 -25n +144=0

n=9 or 16

Hence number of sides can be 9 or 16

I got an answer from here https://answers.yahoo.com/question/index?qid=20090916145105AA3HBsN

We want the whole thing (everything inside the 10-inch radius), minus the smaller circle. Each circle has area A = π r², so:

π (10)² - π (1)² = 99π in² and thier is two more ways to get 99π

I got this anwer from this link https://brainly.com/question/1799139

Answer;

-4.8 ounces for each pork chop

Explanation;

1 pound is equivalent to 16 ounces

Therefore, a 3 pound pork loin is equivalent to;

= 3 × 16

= 48 ounces

Since, they can be cut into 10 pork chops of equal weight, then;

Each pork chop will weigh;  

= 48 ounces/10

= 4.8 ounces

Each pork chop will weigh 4.8 ounces

I got the anwer from this link https://brainly.com/question/17117960

Answer:

Nearest ten

Step-by-step explanation:

Here, we want to know the highest value that can be attained if this number is rounded up to the decimal places given in the question.

The best way to go about this is rounding this number to each of the decimal places and see the one that has the largest value.

We proceed as follows;

Nearest hundred = 300

Nearest ten = 350

Nearest integer = 346

Nearest tenth = 345.7

Nearest hundredth = 345.67

It can be seen from all the above values that the highest value we have is the nearest ten
