Answer:
20
Step-by-step explanation:
28 - {8/2 x (6-2)} + (4 - 2) ^ 3
28 - {4 x 4} + 2^3
28 - 16 + 8
12 + 8
20
Divide by 60 so 105.6/60=1,76 L/min
The THIRD statement is not true.
$2000 (spends a month)
The 5% of $2000 is only $100 for food.
The first statement is true "The household spend $260 per month on the car".
13 % of $2000 = $260
The second statement is true "The household spend $600 per month for rent".
30% of $2000 = $600
The fourth statement is also true "The household spend $200 in savings each month"
10% of $2000 = $200
Answer:
Step-by-step explanation:
If all were ducks, there would be 28·2 = 56 legs. There are 94-56 = 38 more than that. Each cow that replaces a duck adds 2 legs, so there must be 38/2 = 19 such replacements, hence 19 cows. The remaining 28-19 = 9 animals are ducks.
There are 19 cows and 9 ducks.
