Answer:

See explanation

Step-by-step explanation:

Let c be the number of cows and d be the number of ducks.

c cows have 4c feet, d ducks have 2d feet. In total, c cows and d ducks have

4c + 2d = 148 feet.

Divide it by 2:

2c + d = 74.

This gives us that the number of ducks is even and cannot be 0 (because farmer Brwn has ducks). The minimum possible number of ducks is 2, so the maximum possible number of cows is 36.

A turtle can swim 20 meters in 4 seconds. At this rate, how many meters can the turtle swim in 10 minutes?
Snezhnost [94]

Answer:

3,000 meters

Step-by-step explanation:

10*60=600/4=150*20=3000 meters (I highly doubt a turtle can swim three kilometers in 10 min... especially if it's a box turtle).

B) Amount<br>Rs 5760, Interest<br>Rs 1526​
Crazy boy [7]

Given :

Amount, A = 5760 Rs.

Interest in the amount, I = 1526 Rs.

To Find :

We need to find the % rate of interest.

Solution :

Let, us assume it is simple interest.

So,

Interest = \dfrac{price \times  rate \times  time}{100}\\\\1526 = \dfrac{5760 \times r \times m}{100}\\\\r = \dfrac{152600}{5760m}\\\\r = \dfrac{26.5}{m}

Hence, this is the required solution.

Gwar [14]

Answer:

mass on day 1:  3

mass on day 2: 9

mass on day 3: 27

Step-by-step explanation:

using this equation, y = 3^x, you can plug in 1, 2, and 3 for 'x' to get the value of 'y' (which represents the mass on specific days)

3^1 = 3

3^2 = 9

3^3 = 27
