The total number of bills and coins is 14.
Step-by-step explanation:
To minimize the count of bills and coins, start with the largest denominations that fit within the amount.
The change due is $39.49.
Start with:
-$20 bill (largest under $39.49)
Remaining: $19.49
-$10 bill (largest under $19.49)
Remaining: $9.49
-$5 bill (largest under $9.49)
Remaining: $4.49
Then:
4 × $1 bills (to cover $4.49)
Remaining: $0.49
-$0.25 coin (quarter)
Remaining: $0.24
2 × $0.10 coins (dimes)
Remaining: $0.04
4 × $0.01 coins (pennies)
The final composition includes:
1 twenty-dollar bill
1 ten-dollar bill
1 five-dollar bill
4 one-dollar bills
1 quarter
2 dimes
4 pennies
Totaling 14 pieces.
Respuesta: 1.8 bolsas
Explicación paso a paso:
A partir de la pregunta, considerando que Robby tiene 4 4/9 bolsas de comida para mascotas, 2/5 eran comida para perros.
2/5 de 4 4/9 = comida para perros.
Convierte 4 4/9 a fracción impropia= 40/9.
2/5 de 40/9 implica 2/5 × 40/9.
= 16/9.
= 1.78 o 1.8.

Answer: E. The sizes of shoes available for sale in a department store
Step-by-step explanation:
A continuous variable is characterized by:
- a quantitative variable capable of taking an infinite number of values between any two points.
