A steel company sells 48 tons of steel each year.
ddd [48]

Answer:

16 tons

Step-by-step explanation:

To solve the first step is to change years to months because the time periods are in different units. There are 12 months in 1 year. This means that the company sells 48 tons over 12 months. 4 months is the equivalent of 1/3 of 12 months. This means that we can find the amount sold in 4 months by dividing 48 by 3. 48/3 is 16. Thus, the steel company sells 16 tons in 4 months.

Another way to find the answer is to find the unit rate. The unit rate is how many tons are sold in 1 month. Find this by dividing 48 by 12 because this represents the sales of 1 month. 48/12=4, this means that in 1 month, 4 tons of steel are sold. Next, multiply 4 times 4 to find the amount of steel sold in 4 months. 4 times 4 also gives you the same answer of 16.

s2008m [1.1K]

Answer:

20W+50A\geq 350

Step-by-step explanation:

we are given that A robot is expected to filter pollution out of at least 350 liters of air and water.

Also It filters air at the rate of 50 liters per minute, and it filters water at the rate of 20 liters per minute.

The inequality for  number of minutes the robot should filter air (A) and water (W) to meet this expectations can be writte as follows:

20W+50A\geq 350

Hence the required inequality has been formulated.

Answer:

5

alternates

Step-by-step explanation:

The series is for k = 0 to 4, so k = 0, 1, 2, 3, 4.

That is 5 terms.

-1/2 is inside the parentheses and is raised to 0, 1, 2, 3, 4.

A negative number raised to an even integer is positive.

A negative number raised to an odd integer is negative.

The sign of each term in the series alternates.
