Answer:

d + n = 22 and 0.1d + 0.05n = 1.9

Step-by-step explanation:

Let d represents the number of dimes and n represents the number of nickel.

Total of dimes and nickels = 22

Therefore, d + n = 22

1 dime = 10 cents = 0.1

1 nickel = 5 cents = 0.05

Value of 22 dimes and nickel = $1.90

So, 0.1d + 0.05n = 1.9

Hence, d + n = 22 and 0.1d + 0.05n = 1.9 models the given situation.

Hey, hope you're having a great day. :)

The floor of the round hut suggests that this is a cylinder, so.

Lets assess the formula.

A = 3.14 x r^2

A = 3.14 x 2^2

A = 3.14 x 4

A = 12.56.

Hope this helps!

Leviafan [203]

Answer: 2 19/24 hours was spent in practising.

Step-by-step explanation:

During the first hour, they practiced for 5/8 of an hour. During the second hour, they practiced for 2/3 of an hour. This means that the total time for which they practiced in the first 2 hours would be

5/8 + 2/3 = 31/24 hours

During the last two hours, they first practiced for 3/5 of an hour, took a 1/2 hour break and then practiced the rest of the time. This means that the rest of the time for which they practiced is

2 - (3/5 + 1/2) = 2 - 11/10 = 9/10

Therefore, the time they spent practicing in total would be

31/24 + 3/5 + 9/10 = 67/24 =

2 19/24 hours
