Which product is negative?

−2⋅(−4)⋅8⋅(−1)

−7⋅(−3)⋅(−5)⋅(−8)

−3⋅(−4)⋅(−9)⋅0

6⋅(−2)⋅(−3)⋅1

Answers

Answer 1

When I had these kinds of problems, I'd count how many negatives there were. If there more or less negatives to positives, then it is negative. If there's the same amount of positives and negatives, then it's positive since they cancel out! The answer to this is A. (-2)(-4)(8)(-1)=-64.

Answer 2
Final answer:

In mathematics, the product −2⋅(−4)⋅8⋅(−1) is negative. This occurs because it has an odd number (three) of negative numbers being multiplied, leading to a negative product. The other options will give either a positive product or zero.

Explanation:

In the realm of mathematics, when we multiply equal numbers of positive and negative values, we arrive at positive products. However, when we multiply an unequal number of positive and negative values, the product is negative. Let's apply this rule to the given products:

−2⋅(−4)⋅8⋅(−1): It contains three negative numbers, hence product will be negative.−7⋅(−3)⋅(−5)⋅(−8): It contains four negative numbers, hence product will be positive.−3⋅(−4)⋅(−9)⋅0: As one of the numbers is zero, the product will be zero.6⋅(−2)⋅(−3)⋅1: It has two negative numbers, so the product will be positive.

Among the provided choices, only the first product, −2⋅(−4)⋅8⋅(−1), will yield a negative product.

500 grams of sugar occupies a volume of a 0.315 liters whats the density of the sugar in grams per milliliter

Answers

Answer

Density of Sugar is 1.59 grams per milliliter.

Step-by-step explanation:

The answer is required to be given in grams per milliliter.

So we should first convert the values to match the units.

Sugar is given as 500 grams so we don't need to change the units.

Volume is given in liters. So we need to change it to milliliters.

There are 1000 milliliters in 1 liter.

Therefore,

[tex]0.315[/tex] liters = [tex]0.315*1000[/tex] milliliters

                                  =[tex]315[/tex] milliliters

Density of Sugar       = {Number of grams of Sugar/ Volume of the Solvent]

                                  =500 grams / 315 milliliters

                                  =1.59 grams per milliliter (Answer is given to 2 decimal places)

Final answer:

The density of sugar given the mass of 500 grams and a volume of 0.315 liters is calculated as 1.587 grams per milliliter (g/mL) after converting liters to milliliters.

Explanation:

To calculate the density of sugar in grams per milliliter (g/mL), we utilize the formula density = mass/volume.

Given that we have 500 grams of sugar occupying a volume of 0.315 liters, first, we need to convert the volume from liters to milliliters for consistency in units, knowing that 1 liter equals 1000 milliliters.

Thus, 0.315 liters is equal to 315 milliliters.

Applying the formula, the density = 500 grams / 315 milliliters.

Therefore, the density of the sugar is 1.587 g/mL.

This value indicates the mass of sugar that would occupy a one milliliter volume.

Shyam invested money in the stock market. In the first year, his stock increased 20%. He paid his stock broker $300 and then lost $450. He withdrew $500, and then his remaining investment doubled. Shyam’s investment is now worth $7100. How much was Shyam’s original investment?

Answers

Answer:

Shyam's original investment was $4000.

Step-by-step explanation:

Suppose, Shyam's original investment was  [tex]x[/tex] dollar.

In the first year, his stock increased 20%. So, the value of the stock will be: [tex](x+0.20x)=1.20x[/tex] dollar.

He paid his stock broker $300 and then lost $450. So now, the value of the stock will be:  [tex](1.20x-300-450)=(1.20x-750)[/tex] dollar.

He then withdrew $500, so the value of the remaining investment [tex]=(1.20x-750-500)=(1.20x-1250)[/tex] dollar and this remaining investment doubled now.

So, the value of the investment now [tex]=2(1.20x-1250)[/tex] dollar, which is given as $7100.

Thus, the equation will be.......

[tex]2(1.20x-1250)=7100\\ \\ 2.40x-2500=7100\\ \\ 2.40x=7100+2500=9600\\ \\ x=\frac{9600}{2.40}=4000[/tex]

So, Shyam's original investment was $4000.

A. 30%
B. 33%
C. 20%
D. 25%

Answers

The correct answer is B. 33%

In order to find the percentage of success, you need to take the amount of numbers for success and divide by the total number of options. 0-8 represents 9 different options. 0-2 represents 3 possible successes. Therefore, we divide 3 by 9.

Maria needs to make a total of 80 deliveries this week. So far she has completed 48 of them. What percentage of her total deliveries had Maria completed?

Answers

Final answer:

Maria has completed 60% of her total deliveries this week. This was calculated by creating a ratio of completed deliveries to total deliveries, converting this ratio to a decimal, and then converting the decimal to a percentage.

Explanation:

To find what percentage of deliveries Maria has completed, we start by creating a ratio of completed deliveries (48) to total deliveries (80). This ratio is expressed as a fraction, so we write it as 48/80.

Next, we convert this fraction to a decimal by dividing the numerator (top number) by the denominator (bottom number). So, 48 ÷ 80 = 0.6

To convert the decimal to a percentage, we multiply by 100, so 0.6 x 100 = 60%.

Therefore, Maria has completed 60% of her total deliveries so far.

Final answer:

To calculate the percentage of total deliveries Maria has completed, divide the number of completed deliveries by the total number of deliveries and multiply by 100. Thus, Maria has completed 60% of her total deliveries.

Explanation:

To find out what percentage of total deliveries Maria has completed, we can use the method of finding a percentage of a whole. Essentially, this involves taking the number of completed deliveries, dividing it by total number of deliveries and then multiplying by 100.

In Maria's case, she's completed 48 deliveries out of a total of 80 deliveries. Therefore:

Percentage = (Number of completed deliveries / Total deliveries) x 100

So the percentage of completed deliveries = (48 / 80) x 100 = 60%

Therefore, Maria has completed 60% of her total deliveries.

Remember that dividing by a number is the same as multiplying by its reciprocal. To get a number's reciprocal, flip the numerator and denominator around.

In this case, 3/5's reciprocal is 5/3. With this information in mind, flip 3/5 to it's reciprocal, change the division sign to multiplication, then multiply as such:

[tex]\frac{7}{8} \times \frac{5}{3}=\frac{35}{24}[/tex]

Your final answer is 35/24.

12.

Now firstly, we want to convert these mixed fractions into improper fractions. To convert them, multiply the whole number by the denominator then add the numerator and that's your new numerator. In this case:

[tex]2\frac{1}{10}=\frac{2*10+1}{10}=\frac{21}{10}\\\\1\frac{1}{5}=\frac{1*5+1}{5}=\frac{6}{5}\\\\\frac{21}{10}\div \frac{6}{5}[/tex]

Next, we want to convert this expression to multiplication. Similar to before, convert 6/5 to its reciprocal, change the multiplication sign to division, and multiply as such:

[tex]\frac{21}{10}\times \frac{5}{6}=\frac{105}{60}[/tex]

Now you may think that 105/60 is the right answer, however we can simplify it further. The numerator and the denominator have a GCF, or greatest common factor, of 15. With this, divide the fraction by 15/15 as such:

[tex]\frac{105}{60}\div \frac{15}{15}=\frac{7}{4}[/tex]

if n represents a number write an expression for the quantity of four less than the square of this number divided by the quantity five more than four times the number

Answers

A number is represented by = n.

We need to write an expression for "an expression for the quantity of four less than the square of this number divided by the quantity five more than four times the number ".

Let us break the statement into smaller parts.

"The quantity of four less than the square of this number(n)".

Square of n is = n^2.

4 less than n^2 = n^2 -4.

"This number(n) divided by the quantity five more than four times the number"

4 times the number n = 4×n = 4n.

Five more than four times the number = 4n +5.

Therefore, we can repharse given statement by an easy way as:

" 4 less than n^2 is divided by (4n+5)."

or (n^2 - 4) ÷  (4n+5).

In fraction form : [tex]\frac{n^2 - 4}{4n+5}[/tex]

Therefore, final expression would be [tex]\frac{n^2 - 4}{4n+5}[/tex].



Final answer:

The expression for the quantity of four less than the square of a number divided by the quantity five more than four times the number is (n^2 - 4) / (4n + 5)

Explanation:

To write an expression for the quantity of four less than the square of a number divided by the quantity five more than four times the number, we can represent the number as 'n'.

The square of the number is written as n2.

Four less than the square of the number is (n2 - 4).

Five more than four times the number is (4n + 5).

Therefore, the expression for the given quantity is:
