Which of the following are required to find density using the density formula? Check all that apply.A.
Width of the substance

B.
Mass of the substance

C.
Amount of water in the substance

D.
Volume of the substance

Answers

The density formula is Density = Mass / Volume
(B) Mass of substance and (D) Volume of substance are required to find the density.

Final answer:

To find density using the density formula, the required elements are the mass and volume of the substance. Width or the amount of water in the substance is not needed.

Explanation:

The density of a substance can be found using the density formula, which is Density = Mass / Volume. To use this formula, you would need:

Mass of the substance: This is the amount of matter in the substance and is typically measured in grams (g).
Volume of the substance: This is the space that the substance occupies and is typically measured in cubic centimeters (cc or cm3).

The width of the substance or the amount of water in the substance are not required to find density using the density formula.

The combined area of two squares is 45 square centimeters. Each side of one square is twice as long as a side of the other square. What is the length of each side of the larger square?

Answers

a - side of the square
a₁ - arm the small square
a₂ - larger side of the square
2a₁ = a₂ we put into the equation 2
(a₁)² + (a₂)² = 45cm²

2a₁ = a₂
(a₁)² + (2a₁)² = 45cm²
(a₁)² + 4(a₁)² = 45cm²
5(a₁)² = 45cm²
(a₁)² = 9cm²
a₁ = √(9cm²) = 3cm
a₂ = 2a₁ = 2*3cm = 6cm
A₁ = (a₁)² = (3cm)² = 9cm²
A₂ = (a₂)² = (6cm)² = 36cm²
A₁ + A₂ = 9cm² + 36cm² = 45cm²

If I make 11.50 an hour working full time (40 hours a week) how much money do i make a year after deducting 60 dollars of taxes from my pay check every month? ( Keep in mind, some months have 4 weeks and some have 5 wks and I get paid bi-weekly not semi monthly )

Answers

Given:
hourly rate = 11.50
hours worked in a week = 40 hours
taxes per moth = 60

Every month may be 4 weeks or 5 weeks but we know that 1 year has 52.1429 weeks.

Let us compute for the whole year:

Earnings:
11.50 /1 hour * 40 hours/1week * 52.1429 weeks/1year
= 11.50 * 40 * 52.1429/year
= 23,985.734 per year

Taxes:
60 / per month * 12 months / 1 year
= 60 * 12/year
= 720 per year

Net earning per year
23,985.734 - 720 = 23,264.734

Net earning per month
23,264.734 ÷ 12 months = 1,938.81

You will earn 23,264.73 annually from a monthly earning of 1,938.81
