I added 225+45+25 and got 295. Next, I divided 295 by 3 and got 98. (sorry if I'm wrong.)

Three postal workers can sort a stack of mail in 25 ​minutes, 45 ​minutes, and 225 ​minutes, respectively. Time taken if all the three work together is 15min

What is Time?

Time can be described in mathematics as an ongoing and continuous series of events that take place one after another, from the past through the present and into the future. The duration of events or the gaps between them can be measured, compared, or even ordered using time.

The first worker can sort the stack in 25 minutes. So every minute that goes by,

he does 1/25 of the job.

The second employee completes 1/45 of the stack per minute,

While the third employee completes 1/225 of the task.

Minutes are represented by x, and I've set them all to 1 to indicate that a single stack was sorted.

x·1/25 + x·1/45 + x·1/225 = 1

To eliminate all fractions from the calculation, multiply each term by 225.

225x/25 + 225x/45 + 225x/225 = 225

9x + 5x + 1x = 225

15x = 225

x = 225 / 15

x = 15

Hence, It will take 15min to sort the mail if all three work together

Part A:

GIVEN:  Strawberry Juice = [tex]0.85[/tex] liters, Mango Juice = [tex]0.50[/tex] liters, Watermelon Juice = [tex]0.15[/tex] liters, Drank Juice = [tex]0.30[/tex] liters.

-------------------------------------------------------------------------------------------

· Find the expression

In this case, all of them have to be combined to find the expression

Thus,

Expressions in these queries are arithmetical statements that may be defined by the operator, and the following discussion could indeed define a minimum of 2 terms containing the numbers or the variables, or both.

strawberry juice = 0.85 liter

mango juice = 0.50 liter

watermelon juice= 0.15 liter

drank juice = 0.30 liter

solution:

0.85+0.5+0.15 = 1.5

if she drank 0.3, remove it from 1.5, then 1.3

this expression would be : (0.85+0.5+0.15) - 0.3 = 1.2

Answer:

Step-by-step explanation:

4x2 - 8x -12 = 0

divide through by 4

x2 - 2x - 3 = 0

x2 - 3x + x - 3 = 0

(x2 - 3x) + (x - 3) = 0

x(x - 3) + 1(x - 3) = 0

(x + 1) (x - 3) = 0

x + 1 = 0 and x - 3 = 0

x = -1 and x = 3

Answer:

B IS THE ANSWER

Step-by-step explanat

(22x2 -  8x) -  12  = 0

  4x2 - 8x - 12  =   4 • (x2 - 2x - 3)

The first term is,  x2  its coefficient is  1 .

The middle term is,  -2x  its coefficient is  -2 .

The last term, "the constant", is  -3  

Step-1 : Multiply the coefficient of the first term by the constant   1 • -3 = -3  

Step-2 : Find two factors of  -3  whose sum equals the coefficient of the middle term, which is   -2 .

     -3    +    1    =    -2    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -3  and  1  

                    x2 - 3x + 1x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-3)

             Add up the last 2 terms, pulling out common factors :

                    1 • (x-3)

Step-5 : Add up the four terms of step 4 :

                   (x+1)  •  (x-3)

            Which is the desired factorization

4 • (x + 1) • (x - 3)  = 0

A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately  

Any solution of term = 0 solves product = 0 as well.

  Solve  :    x+1 = 0

Subtract  1  from both sides of the equation :  

                     x = -1

   Solve  :    x-3 = 0  

Add  3  to both sides of the equation :  

                     x = 3

Answer:

53/8 = 53/8

Step-by-step explanation:

Here we will simplify 53/8 to its simplest form and convert it to a mixed number if necessary.

In the fraction 53/8, 53 is the numerator and 8 is the denominator.

When you ask "What is 53/8 simplified?", we assume you want to know how to simplify the numerator and denominator to their smallest values, while still keeping the same value of the fraction.

We do this by first finding the greatest common factor of 53 and 8, which is 1.

Then, we divide both 53 and 8 by the greatest common factor to get the following simplified fraction:

58/3

Therefore, this equation is true:

53/8 = 53/8

If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.

53/8 = 6 5/8

Answer:

  log₅(21) = log₅(3) +log₅(7)

Step-by-step explanation:

The relevant relation is ...

  log(ab) = log(a) +log(b)

where the logs have any consistent base.

__

Here, we have ,,,

  ab = 21 = 3·7.

Then ...

  log(21) = log(3) +log(7)

When the logs are to base 5, that becomes ...

Using the compound interest formula, the amount of money in the man's bank account in the second year is $100352

The compound interest relationship is computed using the relation :

Plugging the values into the formula :

Final amount = 80000(1 + 12%)²

Final amount = 80000(1 + 0.12)²

Final amount = 80000(1.12)²

Final amount = $100352

Therefore, the final amount in the second year is $100352
