Round 1.239 to the nearest hundred

Angelina_Jolie [31]

1.24 because the places after the decimal go decimal tenth hundredth thousandth so you look at the second place after the decimal. Then you look at the number after it. In this case because the third number is above a four, it "rounds" up so the three changes to a four. So the answer is 1.24. Hope this helped :)

Charles finished 7 laps around the track. This is 20% of the number of laps he has to do. How many laps must he do?

andrew-mc [135]

To solve this problem, you have to use a proportion:
7/20 = x/100

After setting up the proportion, you have to cross multiply:
20x=700

Now, solve the equation by dividing by 20 on both sides:

x=35

So Charles has 35 laps left.

A box of oat cereal costs $3.90 for 15 ounces. A box of rice of cereal costs $3.30 for 11 ounces. Which box of cereal costs less

Firlakuza [10]

Answer:

The cost of per ounce of oat cereal is $0.04 less than per ounce cost of rice.

Step-by-step explanation:

Given:

Cost of 15 ounces of oat cereal box = $3.90

Cost of 11 ounces of rice box = $3.30

To compare the unit prices of the the boxes.

Solution:

Using unitary method to find the unit prices:

If 15 ounce of oat box cost =$3.90

∴ 1 ounce of oat cereal would cost = $\$\frac{3.90}{15}=\$0.26$

∴ Per ounce cost of oat cereal = $0.26

If 11 ounce of rice box cost =$3.30

∴ 1 ounce of rice would cost = $\$\frac{3.30}{11}=\$0.3$

∴ Per ounce cost of rice = $0.3

Difference in unit costs of oat and rice = $\$0.3-\$0.26=\$0.04$

On comparing the the unit costs of oats and rice, we find out that the cost of per ounce of oat cereal is $0.04 less than per ounce cost of rice.

If the cost of a competing factor of production, such as a machine that also could do the job, rises. This would result in a shi

Harrizon [31]

Keep in mind that we're framing it based on what the first sentence says, which is "If the cost of a competing factor of production, such as a machine that also could do the job, rises".

So if the cost of getting a machine part, various parts, or the entire machine cost rises, then demand for the machine will go down. This will make employers seek out substitutes. In this case, those substitutes would be human labor. As employers demand for labor goes up, the wages will rise assuming the supply of workers is held constant. If the supply of workers increased, then you could argue the wages could go down. So that's why I'm assuming the supply is held in check.
