4^4 = 16

16 x 3.14 = 50.24

Step-by-step explanation:

One number is bigger than another by 406. If the bigger number is divided by the smaller one, you’ll get the quotient 3 and rema

Leviafan [203]

The larger number is 576, the smaller number is 170.

Let x = the larger number and y = the smaller number.

We know that the larger number is 406 larger than the smaller one; therefore
x = y + 406

We also know
$\frac{x}{y}=3\frac{66}{y}$

Substituting for x we have:
$\frac{y+406}{y}=3+\frac{66}{y}$

When we convert mixed numbers to improper fractions, we multiply the whole number by the denominator and add the numerator:
$\frac{y+406}{y}=\frac{3y+66}{y}$

Since the denominators are the same, we can just set the numerators equal
y+406=3y+66

We cannot have a variable on both sides, so we will subtract y from both sides:
y+406-y=3y+66-y
406=2y+66

Subtract 66 from both sides:
406-66=2y+66-66
340=2y

Divide both sides by 2:
340/2 = 2y/2
170=y

The smaller number is 170. Since the larger number is 406 larger, then it is 170+406=576.

kelly is using a bucket to fill up a barrel with water from a well. The barrel holds 25.5 liters.the bucket holds 800 millileter

SVEN [57.7K]

To determine how much of the barrel is left to fill, you must subtract the amount of water already in it from the total mass of the bucket.

25.5 - 5.2 = 20.3 Litres

In order to the fill the entire barrel, Kelly must collect 20.3 Litres of water. You must then covert the measurement from litres to millilitres so that the bucket and barrel are measured in the same units.

20.3L = 20300mL

You must then divide the amount of space left by the mass of the bucket. This will determine the least number of buckets needed to fill the barrel.

20300 <span>÷ 800 = 25.375

That means the you would have to do a minimum on 25.375 buckets to fill the barrel, or 26.

Hope this helps :) </span>
