Answer:

You can can receive 9 different ways to receive change from a ten-dollar bill

Step-by-step explanation:

- Total spent: $9.79

- How much payed: $10

The change will be $10 - $9.79 = 0.21

- Change: $0.21

Possible coins:

penny: 1¢ ($0.01)

nickel: 5¢ ($0.05)

dime: 10¢ ($0.10)

25¢ (this is too high, can't use)

Combinations:

To get 21...

- not ideal but 21 pennies

- 11 pennies + 1 dime

- 1 penny + 2 dimes

- 16 pennies + 1 nickle

- 11 pennies + 2 nickels

- 6 pennies + 3 nickels

- 1 penny + 4 nickels

- dime + nickle + 6 pennies  

- dime + 2 nickels + 1 penny

using dimes:  [10, 10, 1]   [10, 5, 5, 1]   [10, 5, 6x1]   [10, 11x1]

using nickels:  [5, 5, 5, 5, 1]   [5, 5, 5, 6x1]   [5, 5, 11x1]   [5, 16x1]

using pennies: 21x1

So, there are 9 ways to make the change.

Answer:  0.7

This is because the 7 is in the tenths place

0.7 = 7 tenths = 7/10

You could also use long division or a calculator to get this decimal value.

Answer:

0.7

Step-by-step explanation:

To convert a decimal to a fraction, didvide the numerator by the denominator.

7 ÷ 10 = 0.7

note: This fraction is over 10. Any fraction over 10 will have a decimal value in the tenths place.

Answer:

1200 centimeters=12 meters

Step-by-step explanation:

100 centimeters in a meter

so

100x12=1200

Step-by-step explanation:

the area of such a regular shape with n sides is the sum of n isoceles triangles (meaning each triangle has equally long legs) from the center to 2 neighboring corners.

the area of a triangle is

baseline × height / 2

so, for these triangles that means

shape side length × apothem / 2

in our case, n = 6, the side length = 5 cm, the apothem is 4.3 cm. and we get as total area

6 × 5×4.3 / 2 = 3 × 5 × 4.3 = 15 × 4.3 = 64.5 cm²

Answer:

3. The amount of wallpaper for a wall in a bedroom

Step-by-step explanation:

1. The number of towels I can fit in a bathroom cabinet

No, sounds more like volume, since a cabinet has space inside.

2. The amount of ribbon used to decorate from one end of a room to the another

No, sounds like perimeter, since a ribbon would need to cover space in one direction.
3. The amount of wallpaper for a wall in a bedroom

Yes, wallpaper is applied in 2 directions and lays flat on a surface to cover a certain area.

Answer:

the linear approximation formula is based on the equation of the tangent line of a function at a fixed point. The linear approximation of a function f(x) at a fixed value x = a is given by L(x) = f(a) + f '(a) (x - a).

Step-by-step explanation:

This is our y intercept

This is our slope or rate of change

So

The equation becomes

Where m is miles driven

The no. of miles not including any tip the taxi traveled is 22 miles.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, The taxi company charged a pick-up fee of $3.20 plus $2 per mile.

Let, 'm' be the no. of miles and the total fare was $47.20.

Therefore, The numerical form of these statements is,

2m + 3.20 = 47.20.

2m = 47.20 - 3.20.

2m = 44.

m = 44/2.

m = 22.

So, The taxi traveled 22 miles.

Answer:

10 times

Step-by-step explanation:

We have two separate equations that represent this situation:

0.75x   ----> which represents recycling center #1

0.25x + 5.00   -----> which represents recycling center #2

To find the amount of times you would need to visit the recycling centers for the total cost to be the same, put both of these equations equal to each other:

0.75x = 0.25x + 5.00

Now, solve:

0.75x = 0.25x + 5.00                Subtract 0.25x from 0.75x

0.50x = 5.00                              Divide 5.00 by 0.50

x = 10

Thus, you would need to visit the recycling centers 10 times for the total cost to be the same.

Let's check this answer by plugging 10 into both equations:

0.75(10) = 7.5

0.25(10) + 5.00 = 7.5

Since both of the answers are the same, then 10 is the correct answer!
