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

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

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

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

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

-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

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
