Tia cut 4-meter 8-centimeter wire into 10 equal pieces. Marta cut a 540-centimeter wire into 9 equal pieces.How much longer is one of Martha's wires than one of Tina's?

Answers

19.2 centimeters

Explanation: Convert 4m 8cm into cm so it is 408cm. Divide 408 by 10 and you get 40.8cm. Then divide 540 by 9 and you get 60cm. 40.8 and 60 are the measurements of each piece of wire. Subtract 40.8cm from 60cm to get 19.2cm which is the answer.

Hayden brought 4 tickets to a football game. He paid 5% service charge for buying them from a broker. His total cost was $105.00. What was the price for each ticket, not including the service charge?

Answers

Answer: The price for each ticket is $525.

Step-by-step explanation:

Since we have given that

Number of tickets = 4

Total cost = $105.00

Rate of service charge = 5%

Let the original cost be 'x'.

According to question, we get that

4x+0.05* 4x=105\n\n4x+0.2x=105\n\n4.2x=105\n\nx=(105)/(4.2)\n\nx=\$525

Hence, the price for each ticket is $525.

4x + 0.05(4x) = 105.00

x = $25

Akiba Ellis deposits the following in her checking account: 6 five-dollar bills, 5 two dollar bills, 12 one dollar bills, 9 half dollars, 6 quarters, 42 dimes, 10 nickels, 15 pennies, and a check for $97.23. what is her total deposit?

Answers

Answer:

$106.08

Step-by-step explanation:

Given:

6x $5.00

5x $2.00

12x $1.00

9x= 0.50

6x25 cent

42x10 cent

10x5 cent

15=15cent

$97.23

----------------------------------------------------------------------------------

6 five dollar bill is $30.00

so 5 two dollar bill is $10.00

12 one dollar bills is $12.00

9 half dollar bill mean 0.50 cent since it Half and that would make $4.50

6 quarter so 6x25 which equal $1.50

42 dimes and dimes =10 cent so 42x10 which equal $4.20

10 nickels and nickels = 5 cent so 10x5=0.50

15=15 pennies

-------------------------------------------------------------------------------------

30.00+10.00+12.00+4.50+1.50+4.20+0.50+0.15+97.23 =

$106.08 Total Deposit
