What is Unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

thickness of penny = 0.0625

a) if  5 billion pennies minted

Then, height of the stack would be

= 5,000,000,000 x 0.0625

=31,25,00,000 miles

= 31,25,00,000 / 12 x 5280

=4932.13 miles

b) In the past 100 years, nearly 500 billion pennies have been minted.

Now, the height of stack

= 4932.13  x 100

=493213 miles

c) let  x be the number of pennies in a stack which reaches the moon then we have the equation

x × 0.0625 =239,000miles.

x =(239,000 / 0.0625 miles)  ×5280 ×12

x = 38,24,000 x 5280 x 12

x  = 2,42,28,86,40,000

Alonzo will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $50 and costs an additional 0.10 per mile driven. The second plan has no initial fee but costs 0.60 per mile driven. How many miles would Alonzo need to drive for the two plans to cost the same?

Answers

Answer:

100 miles

Step-by-step explanation:

If Alonzo drives 0 miles, then the first plan would cost him 50 dollars and the second plan would cost him nothing.

If Alonzo drives 10 miles, then the first plan would cost him 51 dollars and the second plan would cost him 6 dollars.

From these statements, we can observe that the second plan is increasing at a rate 6 times the first one and will overtake it at one point.

Our solution is the point of intersection between these two functions - where they cost the same.

To find this, equate

0.1x + 50 = 0.6x

where x is the number of miles Alonzo drives,

multiply the equation with 10 to get,

x + 500 = 6x

subtract x,

5x = 500

and divide 5,

x = 100.

So at 100 miles, both plan 1 and 2 will cost 60$. This is our answer. Good Luck!

How to Round:

If the number following the number you're going to round up is 5 or above, (5, 6, 7, 8, or 9), then round up. (E.X. 29 rounded up is 30. Since 9 is above 5, you will round up.

On the other hand, if the number following the number you're going to round is 4 or below, (4, 3, 2, or 1), you don't round up, instead you keep it the same, and if they're are decimals, you turn the following numbers to 0s. (E.X. 32.4536 rounded to the nearest hundredth (32.4536) is 32.45. Since 3 is less than 4, you're not going to round up. The number in the hundredth's place stays the same (5), and the following rest turn to 0s. Leaving you with 32.45

About 3.14 centimeters


About 12.56 centimeters


About 25.12 centimeters


About 1.02 centimeters

Answers

Answer:

c

Step-by-step explanation:

Answer:

The difference in circumference is about 25.12 centimeters

Step-by-step explanation:

You find diameter by multiplying the radius by 2. So with that being said, the diameter of circle A is 18cm and the diameter of circle B is 10cm.

You calculate circumference by multiplying ur diameter by pi (3.14)

18 cm x 3.14 = 56.52 cm so the circumference of Circle A is 56.52 cm.

10cm x 3.14 = 31.9 cm so the circumference of circle B us 31.9 cm.

56.56

-31.9

= 24.62

24.62 is the around  25.12 cm
