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:

x < - 25

Step-by-step explanation:

| x + 3 | > 22

Case 1 : x + 3 > 22 [WORKED]

x > 22 - 3

x > 19

Case 2: - (x + 3) > 22

- x - 3 > 22

- x > 22 + 3

x < - 25

As case 1 and 2 don't overlap, so the answer of x should be:

x < - 25 or x > 19

Answer:

6n-3

Step-by-step explanation:

You can see the sequence is ascending by 6 each time so the nth term is 6n.

The 'zero term' would be -3 so the equation would be 6n-3.

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

TO CHOOSE THE CORRECT OPTION

The ratio of 2 gallons to 3 quarts

A) 8 to 3

(B) 3 to 8

(C) 3 to 2

(D) 2 to 3

EVALUATION

Here we have to find the ratio of 2 gallons to 3 quarts

We know that

1 gallon = 4 quarts

∴ 2 gallon = 8 quarts

Hence the required ratio

When you divide 300 by 24 you will get 12.5 but you can’t make half a sale so you would have to round up to 13

Answer:

C. 48.98 m

Step-by-step explanation:

[tex]2\pi(7.8) = 15.6\pi = 49.01[/tex]

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.

x = 26

angle QOR = 31

angle ROS = 59

Step-by-step explanation:

[tex](x + 5) + (2x + 7) = 90\\ 2x + x + 5 + 7 = 90 \\ 3x + 12 = 90 \\ 3x = 90 - 12 \\ 3x = 78 \\ x = 78 \div 3 \\ x = 26[/tex]

Answer:

The value of x = 109°

angle PQS = 24°

Step-by-step explanation:

24° + 47° + x = 180° { angles on straight line }

=> 71 ° + x = 180°

=> x = 180° - 71°

=> x = 109°

Now,

Angle PQS = 24°

angle PQS = angle QSR { alternative angle }

Step-by-step explanation:

a)(i) x=109°

(ii)It's given that PST is straight line then PST=180°,and

PST=QSP+QSR+x

180° =47°+24°+x

180°=71°+x

180°-71°=x

109°=x

b)(i)PQS=71°

(ii)we know opposite angles are equal in parallelogram

so PSR=PQR=71°

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!
