The milliliters of acid in the solution is 74.1 milliliters

<h3>How to determine the milliliters of acid in the solution?</h3>

The given parameters are:

Volume of the solution = 388 milliliters

Proportion of acid in the solution = 19.1%

The milliliters of acid in the solution is then calculated as:

Milliliters = Volume of the solution * Proportion of acid in the solution

Substitute the known values in the above equation

Milliliters = 388 milliliters * 19.1%

Evaluate the product

Milliliters = 74.1 milliliters

Hence, the milliliters of acid in the solution is 74.1 milliliters

Chien always works 20 hours/week at $15/hour and gets paid every 2 weeks.
Leto [7]

Answer:

  • $600
  • net pay
  • taxes, insurance, retirement plan contributions
  • net pay

Step-by-step explanation:

The gross pay that shows up on your paycheck is the sum of wages, commissions, and any other earnings your employer may share with you (tips, insurance offsets, bonuses). From this gross pay, government regulations may require the deduction of taxes of various kinds. Your employer may deduct the cost of insurance, and you may voluntarily have amounts deducted for additional taxes, insurance, union dues, or retirement plan contributions. The pay that you take home is the net pay after these deductions.

__

Chien gets paid at the rate of $15 per hour for 20 hours per week and 2 weeks per pay-period. We are not told of any other earnings or contributions to his gross pay. So, it will be ...

  ($15/h)(20 h/wk)(2 wk/period) = $600/period

Chien's gross pay will be $600 each pay period.

__

As discussed above, "net pay" and "take-home pay" are synonymous.

__

As discussed above, there may be a variety of deductions from his gross pay that will reduce his net pay. Often the largest of these is income tax together with Social Security tax. There may be additional deductions for insurance, union dues, health plan contributions, and retirement plan contributions.

__

Chien's budget should be based on money he <em>actually has available to spend</em>. That would generally be his net pay.

If Chien is considering changing jobs or his family situation, changes to payroll deductions may figure into his budget. Ordinarily, those costs would be considered "fixed" and not subject to a budgeting process.

Helena creates two similar rectangles using exactly 100 cm of string. The smaller rectangles width and length are 4 cm by 6 cm r
Misha Larkins [42]

Answer:

The dimensions of the larger rectangle are 24\ cm of length by 16\ cm of width

Step-by-step explanation:

Let

x-----> the length of the larger rectangle

y-----> the width of the larger rectangle

we know that

\frac{x}{y}=\frac{6}{4} ------> by similar rectangles

x=1.5y -----> equation A

<u>Find the perimeter of the smaller rectangle</u>

P=2(6+4)=20\ cm

<u>Find the perimeter of the larger rectangle</u>

Subtract  the perimeter of the smaller rectangle from 100 cm of string

P=100-20=80\ cm

Remember that

80=2x+2y ------> 40=x+y ------> equation B

substitute equation A in equation B

40=1.5y+y

2.5y=40

y=16\ cm

Find the value of x

x=1.5(16)=24\ cm

The dimensions of the larger rectangle are 24\ cm of length by 16\ cm of width

How can you isolate the variable x on one side of an inequality
Tcecarenko [31]

you combine like terms first.

for example: 2x=2+5

add up the two plus 5 so that will give you seven then you're going to divide 2 by 7 so that you isolate the x and you'll get your answer.
