Final answer:
To divide 0.4 by 0.02, transform the division problem into 40 divided by 2 by moving the decimal places to the right, resulting in the answer 20.
Explanation:
To solve the division of two decimal numbers, 0.4 divided by 0.02, you can follow these steps:
First, count the number of decimal places in the divisor (0.02), which is 2.Move the decimal place in both the divisor and the dividend to the right by the same number of places, turning 0.02 into 2 and 0.4 into 40.Now divide the transformed dividend (40) by the transformed divisor (2).The division now looks like 40 ÷ 2, which equals 20.
So, 0.4 divided by 0.02 equals 20. This method allows us to divide decimal numbers by converting them into whole numbers, simplifying the calculation.
Find two numbers with a sum of 20 and a difference of 14.
Name the property the equation illustrates.
8.2 + (–8.2) = 0
Answer:
The name of the property the equation illustrates is the Inverse Property of Addition.
Step-by-step explanation:
The Inverse Property of Addition says that if you add a number to the negative version of itself, the numbers will cancel out and the result will be 0. In other words, if you add 8.2 + (–8.2), the answer will always be 0.

alex wants to buy the same number of stamps and envelopes dancer sold in packs of 14 and envelopes are sold and packs of 10 what is the lease number of each he could buy to have the same number of stamps and envelopes
Final answer:
To have the same number of stamps and envelopes, Alex would have to find the Least Common Multiple of 14 and 10, which is 70. Therefore, he should buy 5 packs of each.
Explanation:
Alex wants to buy the same number of stamps and envelopes, but they come in different pack sizes: stamps in packs of 14 and envelopes in packs of 10.
To find the least number of each he could buy to have the same number of each, we need to find the Least Common Multiple (LCM) of 14 and 10. The LCM of 14 and 10 is 70.
So, Alex would need to buy 5 packs of envelopes (since 70 divided by 10 equals 7) and 5 packs of stamps (since 70 divided by 14 equals 5) to have the same number of stamps and envelopes, which is 70 of each.

Every week, Mr. Kirkson uses 3 1/6 gallon of water to water every 1/3 square foot of his garden. How many gallons of water does Mr. Kirkson use per square foot to water his garden each week?
3 1/6 / 1/3 =
19/6 / 1/3 =
19/6 * 3/1 = 57/6 = 9 1/2 gallons per square foot
Answer:
Mr. Kirkson uses 9.60 gallons of water per square foot to water his garden each week.

A high school basketball team scores 85 points in a playoff game. The team leaders are Greg and Tremaine who scored a total of 38 points. If Tremaine scored 8 more points than Greg, how many points did Greg and Tremaine score individually?
Answer:
Total Points scored by team leaders are Greg and Tremaine=38 points
Let Points scored by Greg =x points
Then , Points scored by Tremaine =(x+8) points
So, writing the condition in equality form
x +x+8=38
2 x =38-8
2 x=30
Dividing both sides by ,2
x=15
Points scored by Greg =15 points
Then , Points scored by Tremaine =(15+8)=23 points

What is the unit rate for 768.57 m 41.1 h? Enter your answer, as a decimal, in the box.
Final answer:
To find the unit rate, divide 768.57 meters by 41.1 hours resulting in a unit rate of 18.70 meters per hour.
Explanation:
The question asks for the unit rate of 768.57 meters over 41.1 hours. To calculate this, divide the distance by the time:
First, write the given ratio as a fraction. 768.57 m over 41.1 h.Second, divide 768.57 by 41.1 to find the unit rate in meters per hour. 768.57 m ÷ 41.1 h = 18.70 m/h (rounded to two decimal places as per the significant figures in the original distance).The division, 768.57 m ÷ 41.1 h, yields a unit rate of 18.70 m/h (rounded to two decimal places to match the precision of the original distance). Hence, the unit rate for this scenario is 18.70 meters per hour.
Therefore, the unit rate is 18.70 meters per hour.

(B). Dividing binomials
(C). Subtracting binomials
(D). Multiplying binomials
Explanation:
Consider the two polynomials [tex]x + 1[/tex] and [tex]2x + 4.[/tex]
Add the two polynomials [tex]x + 1[/tex] and [tex]2x + 4.[/tex]
[tex]\begin{aligned}{\text{Add}} &= x + 1 + 2x + 4\\&= 3x + 5\\\end{aligned}[/tex]
The result after adding is a polynomial. Therefore, adding binomials is a closed for polynomials.
After dividing the two polynomials [tex]x + 1[/tex] and [tex]2x + 4[/tex] the result is a rational expression.
Therefore, dividing binomials operation is not closed for polynomials.

A cruise ship is traveling at a speed of 20 knots . A knot is approximately equal to 1.151 miles per hour. What is the approximate speed the ship is traveling in yards per second ? Round to the nearest tenth.
The cruise ship's speed, starting at 20 knots, can be translated to approximately 11.2 yards per second when converted to miles per hour, yards, and seconds.
Explanation:To find the cruise ship's speed in yards per second, we first need to convert knots to miles per hour by utilizing the equivalence of 1 knot to 1.151 miles per hour. Therefore, the ship is traveling approximately 20 * 1.151 = 23.02 miles per hour.
Next, we need to convert the ship's speed from miles per hour to yards per second. There are 1760 yards in a mile and 3600 seconds in an hour. The conversion will be 23.02 miles/hr * 1760 yards/mile divided by 3600 seconds/hr, which results in an approximate speed of 11.2 yards per second when rounded to the nearest tenth.
