The multiplication of two or more quantities may be expressed as the ? of the same quantities.
Answer:
sum
Step-by-step explanation:
We know that, 'multiplication of two or more quantities can be expressed as the SUM of the same quantities'.
This means that 'multiplication of two or more terms is equal to adding as many copies of one of them'.
i.e. a × b = a + a + .... ( 'b' number of times ) = b + b + ... ( 'a' number of times )
Let us consider few examples,
A. 2 × 4 = 8
So, we can have that,
2 × 4 = 2 + 2 + 2 + 2 = 8 i.e. we add the number 2 four times.
2 × 4 = 4 + 4 = 8 i.e. we add the number 4 two times.
B. 3 × 7 = 21
3 × 7 = 3 + 3 + 3 + 3 + 3 + 3 + 3 = 21 i.e. we add the number 3 seven times.
3 × 7 = 7 + 7 + 7 = 21 i.e. we add the number 7 three times.
Hence, 'The multiplication of two or more quantities may be expressed as the SUM of the same quantities'.
What is the quotient of 3 ÷ 2 1/3, reduced to lowest terms?\
Final answer:
To find the quotient of 3 ÷ 2 1/3, convert the mixed number to an improper fraction (7/3), find the reciprocal (3/7), and multiply it by 3 to get 9/7, which is the answer in lowest terms.
Explanation:
The quotient of 3 ÷ 2 1/3 can be found by first converting the mixed number 2 1/3 to an improper fraction. The mixed number 2 1/3 is equal to ⅔, which when summed (2 * 3 + 1), gives us 7/3. To divide by a fraction, you multiply by its reciprocal. Thus, we have 3 × ⅓ (which is 3/7). Multiplying these we get 9/7, which cannot be further simplified. Therefore, the quotient in lowest terms is 9/7.
The quotient of 3 ÷ 2 1/3 is found by converting 2 1/3 to an improper fraction (7/3), taking the reciprocal (3/7), and multiplying it with 3. The result is the fraction 9/7, which is already in lowest terms.
Explanation:To find the quotient of 3 ÷ 2 1/3, we first convert the mixed number to an improper fraction. The mixed number 2 1/3 is equivalent to 7/3 (because 2 × 3 + 1 = 7). To divide by a fraction, we multiply by its reciprocal. Therefore, we need to multiply 3 by the reciprocal of 7/3, which is 3/7.
The multiplication is straightforward: 3 × 3/7. We multiply the numerators (3 × 3) to get 9, and the denominators (1 × 7) to get 7, so we have 9/7. Since 9 and 7 have no common factors other than 1, 9/7 is already in its lowest terms. Thus, the quotient is 9/7 or 1 2/7 when expressed as a mixed number.

to mail a cardboard box, you measure its size and mass. It is 55cm long , 25cm wide and 20 cm high. The mass of the box is 4kg. What is the density of the boxes in grams over cm squared
Answer:
Density is usually expressed as grams per cubic centimeter.
Volume = 55 * 25 * 20 = 27,500 cc
Density = Mass / Volume = 4,000 grams / 27,500 cc
= 0.1454545455 grams/cc
which is an extremely low density
Step-by-step explanation:
The density of the box is found by dividing its mass (4000 grams) by its volume (27500 cubic centimeters), resulting in a density of approximately 0.1455 grams per cubic centimeter.
Explanation:To calculate the density of the box, you must find the mass per unit volume. The mass given is 4 kg, which is equivalent to 4000 grams since 1 kg = 1000 grams. To find the volume, multiply the length by the width by the height of the box:
Volume = Length × Width × Height = 55 cm × 25 cm × 20 cm = 27500 cm³
Now, divide the mass of the box by the volume to get the density:
Density = Mass / Volume = 4000 g / 27500 cm³ ≈ 0.1455 g/cm³
Therefore, the density of the box is approximately 0.1455 grams per cubic centimeter (g/cm³).

Dan’s ice cream comes in cartons of two sizes.The large carton holds4 1/2 pounds.the small carton holds 1 3/4 pounds less .how much ice cream does the small carton hold?
Answer:
2 and 3/4 lbs
Step-by-step explanation:
4 and 1/2 is equal to 9/2. If you multiply 4 by 2 and then add 1, you get 9, and put it over 2 because that is the denominator in the mixed number. Using the same method, we can find that 1 and 3/4 is equal to 7/4. However, the denominators are different, so we need to change that so they will be common. We can change 9/2 to 18/4 by multiplying both the numerator and the denominator by 2. This is technically the same as multiplying by 2/2, which is equal to 1, so the fraction will be equivalent, since anything multiplied by 1 is itself. Now we have 18/4 for the large carton and 7/4 for the small carton. Since the denominators are the same, they do not change. Just subtract the numerators to get 11, and then put it over 4 to get 11/4. In mixed number form, this is 2 and 3/4 lbs because 4 goes into 11 twice (8) and then you will have 3 left over. 8+3 = 11
Answer:

eleanor purchased $2568 worth of stock and paid her broker a 0.5% fee. She sold the stock when the stock price increased to 3928 using an online broker that charged $7 per trade. What are her net proceeds?
Answer:
Eleanor's net proceeds would be $1340.16.
Step-by-step explanation:
If Eleanor purchased $2568 worth of stock and paid a 0.5% broker fee, she would have to pay $12.84 for the service, which is what we get when we multiply her initial purchase by the percentage (0.005). When Eleanor sold the stock at $3928, she had to pay a flat fee of $7 for the trade, decreasing her overall profit by $7, or $3921. Subtracting her initial investment from the overall profit gives Eleanor a net proceed of $1340.16.
Eleanor's net proceeds from her stock sale, after accounting for both the original broker's fee and the online trading fee, are $3908.16.
Explanation:To calculate Eleanor's net proceeds, we first need to calculate the fee she paid to her first broker. At 0.5% of $2568, that comes to $2568 * 0.005 = $12.84.
Next, she sold her stocks for $3928 using an online broker that charges a flat rate of $7 per trade. So, she paid another $7 in fees.
Therefore, the total fees she paid are $12.84 (first broker) + $7 (second broker) = $19.84.
Finally, to find her net proceeds, we subtract the total fees from the amount she sold her stocks for: $3928 - $19.84 = $3908.16.
So, Eleanor's net proceeds from selling her stocks are $3908.16.

An airplane is flying from New York City to Los Angeles. The distance it travels in miles, d, is related to the time in seconds, t, by the equation d=0.15t. How fast is the airplane flying? Be sure to include the units. 60 mph How far will it travel in 30 seconds? How long will it take to go 12.75 miles?
For a 30 second flight, the airplane will travel 4.5 miles. To cover a distance of 12.75 miles, it will take 85 seconds.
The relationship between the distance an airplane travels and the time it takes is given by the equation [tex]d=0.15t[/tex].
Here, d stands for distance in miles and t for time in seconds. The coefficient 0.15 in this equation represents the speed of the airplane in miles per second.
To find how fast the airplane is flying, we must convert this speed to a more familiar unit, such as miles per hour.
Since there are 3600 seconds in one hour, the airplane's speed in miles per hour (mph) is
[tex]0.15 miles/second \times 3600 seconds/hour = 540 mph[/tex]
Now, to determine how far the airplane will travel in 30 seconds, we substitute t with 30 in the original equation:
[tex]d = 0.15 \times 30[/tex], yielding a distance of 4.5 miles.
To calculate how long it will take the airplane to go 12.75 miles, we use the original equation but solve for t:
[tex]t = \frac{d}{0.15} t = \frac{12.75}{0.15}[/tex]
which simplifies to 85 seconds.

x-2 1/4=1/18
Answer: x = 2 11/36
Step-by-step explanation:
x-2 1/4 = 1/18
Isolate x: x - 2 1/4 + 2 1/4 = 1/18 + 2 1/4
x = 4/72 + 2 18/72
x = 2 22/72
x = 2 11/36
Check:
2 11/36 - 2 1/4 = 1/18
2 11/36 - 2 9/36 = 1/18
2/36 = 1/18
1/18 = 1/18
4. Find the length of AB if A is located (-2,0) and B is located at (5,0)
5. If EF=9x+14, FG=56, and EG=250, find the value of x. The drawing is not to scale.
Answer: 4. 7 unit
5. 20 unit
Step-by-step explanation:
4. Since, A≡ (-7,0) and B≡ (5,0)
Thus, By the distance formula,
[tex]AB = \sqrt{(5-(-2))^2+ (0-0)^2}[/tex]
⇒ [tex]AB = \sqrt{(5+2)^2+ (0)^2}[/tex]
⇒ [tex]AB = \sqrt{(7)^2+ (0)^2}[/tex]
⇒ [tex]AB = \sqrt{49+0}[/tex]
⇒ [tex]AB = \sqrt{49}[/tex]
⇒ AB = 7 unit
5. Here EF = 9x + 14, FG = 56 and EG= 250
But, According to the given diagram,
EF + FG = EG ( because G divides the line EG )
⇒ 9x + 14 + 56 = 250
⇒ 9x + 70 = 250
⇒ 9x = 250 - 70 ( By subtracting both sides by 70)
⇒ 9x = 180
⇒ x = 20 ( by dividing both sides by 9 )
Thus, the value of x is 20.
