How much water should be added to 3 gallons of pure alcohol in order to obtain a solution that is 50% alcohol?

Answers

Answer 1

Answer: 3 gallons of water

Step-by-step explanation:

3 gallons of alcohol +3 gallons of water = 6 gallons total

alcohol = 3/6 = 50%

Answer 2
Let x=amount of water added.

let 3+x=amount of alcohol and water in 15% solution.

Let 3 gallons of alcohol=percentage of alcohol*volume of solution

3=0.15*(3 + x)

3=0.45 + 0.15x

2.55=0.15x

2.55/0.15=x or 17 gallons of water added=x

  14. ∠UVS = 63.6°

  15. ∠TWU = 90°

  16. ∠TUV = 116.4°

  17. UW = √111 ≈ 10.5

  18. SU = 2√111 ≈ 21.1

  19. VT = 34

Step-by-step explanation:

The relevant relations for a rhombus are ...

diagonals bisect each other at right angles, dividing the figure into 4 congruent right trianglesthe diagonals bisect the vertex anglesadjacent vertex angles are supplementary

__

14.

Angle UVS is double the measure of angle UVW. 2×31.8° = 63.6°.

  angle UVS = 63.6°

__

15.

As we said above, the angles where the diagonals cross are right angles.

  angle TWU = 90°

__

16.

Angle TUV is supplementary to angle UVS. 180° -63.6° = 116.4°

  angle TUV = 116.4°

__

17.

UW is found using the Pythagorean theorem.

  UW² +TW² = TU²

  UW² = TU² -TW² = 20² -17² = 111

  UW = √111 ≈ 10.536

__

18.

The whole diagonal is twice the measure of half of it. SU = 2×UW

  SU = 2√111 ≈ 20.071

__

19.

The whole diagonal is twice the measure of half of it. 2×17 = 34

You just bought a new laptop and paid an initial payment of $150.00. You will make 12 payments of $69.50. How much will the computer cost if your state charges 6% sales tax on the total sale.

Answers

The computer will cost $924.96 after 6% tax.

Total cost of laptop

The initial payment of the laptop made = $150.00

The remaining balance that would be made = 12 × 69.50

=$834

Therefore total cost of laptop before tax = 834 + 150

= $984

But tax is 6% of total cost =

[tex] \frac{6}{100} \times 984[/tex]

[tex] \frac{5904}{100} [/tex]

= $59.04

Therefore, total cost of laptop after tax = 984 - 59.04

= $924.96

Answer:

5. x = 39°

6. x = 46°

7. x = 24°

8. x = 19°

Step-by-step explanation:

5.

Base angles are the same due to it being an isosceles triangle

Sum of angles in triangle = 180°

2x + 2x + (x - 15) = 1804x + x - 15 = 1805x - 15 = 1805x = 195x = 39

6.

Angle VZW and XZW are supplementary, meaning that they add up to 180°

3x + 17 + (x - 9) = 1803x + 17 + x - 9 = 1804x + 8 = 1804x = 184x = 46°

7.

Sum of angles in a straight line add up to 180°

(2x - 4) + (3x + 5) + (2x + 11) = 1802x - 4 + 3x + 5 + 2x + 11 = 1807x + 12 = 1807x = 168x = 24

8.

All angles add up to 90°

x + (x + 4) + (3x - 9) = 90x + x + 4 + 3x - 9 = 905x - 5 = 905x = 95x = 19

season. Together, these two players brought home 232 runs during the 2005 regular season. How many runs batted in did player A and player Beach account for?
CE
Player A had runs and player B had runs batted in for the 2005 regular season.

Answers

Answer:

ok so we trying to find out how many each batted so lets make this a system of equation

first we now that combined they are 232 so

a+b=232

then we now that b is 18 less then a so

a-18=b

the system of equation is

a+b=232

a-18=b

so we now what b is so we can just plug that in

a+a-18=232

2a-18=232

2a=250

a=125

then we can just plug this back in

125+b=232

b=107

a=125

b=107

Then, to find the new weight of the ship, you can subtract the 20% that was just found (88,124) from the ship's original weight (440,620) to get:

440,620 - 88,124 = 352,496

Carmen is a professor at a local university. In collecting data on her Introduction to Business course for a year, she wants to calculate the z-score for a student who scores a 92 on the final exam. The mean and the standard deviation scores on the exam are 76 and 6, respectively. Calculate the z-score.

Answers

The z score of a student who scores a 92 on the final exam is 2.67.

Z score

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (x - μ) / σ

where x is the raw score, μ is the mean and σ is the standard deviation

Given that σ = 6, μ = 76. For a raw score of 92:

z = (92 - 76) / 6 = 2.67

The z score of a student who scores a 92 on the final exam is 2.67.
