Calculus

To answer the questions made, the following calculations must be made:

1. If 15 apricots cost R5.60, how many apricots will cost R10.08?

5.60 = 1510.08 = X10.08 x 15 / 5.60 = X151.2 / 5.6 = X27 = XTherefore, 27 apricots will cost R10.08.

2. How much will it cost for 1kg of polony if 0.35 kg of polony costs R25.10?

0.35 = 25.101 = X25.10 / 0.35 = X71.71 = XTherefore, 1 kg of polony will cost R71.71.

3. If 12.5 kg of sugar cost R90, how much will 7.2 kg of the sugar cost?

12.5 = 907.2 = X7.2 x 90 / 12.5 = X648 / 12.5 = X51.84 = XTherefore, 7.2 kg of sugar cost R51.84.

4. A scooter uses 6.5ℓ petrol to travel a distance of 130 km. How much petrol will it use to travel a distance of 80km?

130 = 6.580 = X80 x 6.5 / 130 = X520 / 130 = X4 = XTherefore, it will use 4 liters of oil to travel a distance of 80km.

5. Peter used 5ℓ of paint to paint a wall that is 8m long and 5m high. How many square meters can Peter paint with 1ℓ of paint?

8 x 5 = 4040 / 5 = 8Therefore, Peter can paint 8 square meters with 1 liter of paint.

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°

UW is found using the Pythagorean theorem.

  UW² +TW² = TU²

  UW² = TU² -TW² = 20² -17² = 111

Player Aled a baseball league in runs batted in for the 2005 regular season. Player B, who came in second to player A, had 18 fewer runs batted in for the 2005 regular
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

Answers

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

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.

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
