The Harris Family Entertainment Club deposited R3 600 in an investment account a year ago, with the intention of purchasing new equipment in four years’ time. Today, it is adding a further R5 000 to this account. Plans are to make a final deposit of R7 500 in the account next year. How much will be available when the family is ready to buy the equipment, assuming the investment earns a 7% rate of return?
Answer:
Step-by-step explanation:
To calculate this, we need to use the formula for future value of an annuity:
FV = PMT x ((1+i)^n - 1)/i
Where:
PMT = the periodic payment (or deposit)
i = the interest rate per period
n = the number of periods
In this case, there are three deposits:
- R3,600 deposited one year ago
- R5,000 deposited today
- R7,500 to be deposited next year
We can calculate the future value of each of these deposits separately, and then add them together to get the total future value:
Future value of R3,600 deposited one year ago:
n = 4 (4 years until the equipment purchase)
i = 7% per year
PMT = R3,600
FV = R3,600 x ((1+0.07)^4 - 1)/0.07 = R4,661.07
Future value of R5,000 deposited today:
n = 3 (3 years until the equipment purchase)
i = 7% per year
PMT = R5,000
FV = R5,000 x ((1+0.07)^3 - 1)/0.07 = R6,885.02
Future value of R7,500 to be deposited next year:
n = 2 (2 years until the equipment purchase)
i = 7% per year
PMT = R7,500
FV = R7,500 x ((1+0.07)^2 - 1)/0.07 = R8,733.63
Total future value = R4,661.07 + R6,885.02 + R8,733.63 = R20,279.72
Therefore, there will be R20,279.72 available when the family is ready to buy the equipment, assuming a 7% rate of return on the investment.
Natasha worked for part of the year before receiving a raise in her hourly rate of pay. The graph below shows the amount of money she has made this year and the hours she has worked since she received the raise. What was the initial amount of money Natasha made?
Answer:
Unfortunately, I cannot see the graph you are referring to since we are communicating through text. However, based on the information given, we can make some general observations.
We know that Natasha received a raise in her hourly rate of pay at some point during the year. Before the raise, she earned some initial hourly rate of pay. Let's call this initial rate of pay "x". Let's also assume that she worked for "h" hours before receiving the raise, and "k" hours after receiving the raise.
We can write an equation to represent the total amount of money she made this year:
Total amount of money = (initial hourly rate of pay x number of hours worked at the initial rate) + (new hourly rate of pay x number of hours worked at the new rate)
Using the variables we defined earlier, we can write:
Total amount of money = (x × h) + ((x + y) × k)
where y is the increase in her hourly rate of pay after the raise.
We also know that she earned a certain amount of money before the raise. Let's call this amount "M". This means that:
M = x × h
Solving for x, we get:
x = M/h
Substituting this expression for x into the first equation, we get:
Total amount of money = (M + yh) + ((M/h + y) × k)
We don't know the values of M, y, h, or k, so we cannot determine the initial hourly rate of pay x or the total amount of money Natasha made this year. However, we have set up an equation that can be used to solve for these values if we have more information.
In PQR, PQ= 5.4, QR= 3.6, and PR=6.2. To the nearest Tenth, what is M∠R
Therefore , the solution of the given problem of angles comes out to be M∠R measured at 45.4 degrees, to the closest tenth.
An angle meaning is what?The intersection of the lines that form a skew's ends determines the size of its biggest and smallest walls. There's a possibility that two paths will intersect at a junction. Angle is another outcome of two things interacting. They mirror dihedral forms the most. A two-dimensional curve can be created by placing two line beams in various configurations between their ends.
Here,
To determine the size of angle R in triangular PQR, we can apply the Law of Cosines:
=> cos(R) = (PQ₂ + PR₂ - QR₂) / (2 * PQ * PR)
=> cos(R) = (5.4₂ + 6.2₂ - 3.6₂) / (2 * 5.4 * 6.2)
=> cos(R) = 0.6960917
When we calculate the inverse cosine of both sides, we obtain:
=> R = cos⁻¹(0.6960917)
=> R equals 45.4 degrees
Angle R in triangle PQR is therefore measured at 45.4 degrees, to the closest tenth.

Find the unknown dimension of a rectangle if its perimeter is 254 meters and one
dimension measures 6 meters. Use labeled sketches and equations to model and
solve this problem. Show your work. Label your answer with the correct units.
The perimeter does indeed equal 254 meters, which confirms that our answer is correct.
What in mathematics is the perimeter?Any two-dimensional closed shape's perimeter is defined as the entire distance encircling it. The perimeter of a rectangle, such as the following: Square perimeter equals the sum of its four edges. Rectangle perimeter equals the sum of its four edges.
Let's call the rectangle's unidentified size x.
P = 2l + 2w, where l is the length and w is the breadth, gives the perimeter of a rectangle.
So that we can create an equation:
254 = 2l + 2(6)
Simplifying the right side:
254 = 2l + 12
Subtracting 12 from both sides:
242 = 2l
Dividing both sides by 2:
121 = l
Consequently, the rectangle's undetermined measurement (length) is 121 metres.
We can compute the perimeter using both variables to confirm our conclusion:
P = 2(121) + 2(6) = 242 + 12 = 254

A brick of mass 2 kg falls through water with an acceleration of 2 ms 2. The total force of the resistance is N.
The calculated value of the force of the resistance is 15.62 N
Calculate the force of the resistanceWe can use Newton's Second Law of Motion to solve this problem. The formula is:
F = m*a
where F is the net force, m is the mass of the object, and a is the acceleration.
In this case, the brick is falling through water, so there are two forces acting on it:
gravity (pulling it down) water resistance (slowing it down).The net force is the difference between these two forces:
F_net = F_gravity - F_resistance
The weight of the object is:
F_gravity = m*g
So, we have
F_gravity = 2 kg * 9.81 m/s^2 = 19.62 N
Now we can use the formula for net force to find the force of water resistance:
F_net = F_gravity - F_resistance
F_resistance = F_gravity - F_net
F_resistance = 19.62 N - m*a
This gives
F_resistance = 19.62 N - 2 kg * 2 m/s^2 = 15.62 N
Therefore, the force of water resistance is 15.62 N.

Can the sides of a right triangle have lengths 5, 15, and √250? Explain.
A triangle must have a third side that is bigger than the sum of any two of its sides. There cannot be a triangle with these side lengths because in this instance, 5 + 15 = 20 is not greater than 250.
Application of Pythagoras theoremTo check whether the given lengths can form the sides of a right triangle, we need to check if they satisfy the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Let's label the sides of the triangle as a, b, and c, where c is the hypotenuse. Then, the Pythagorean theorem can be written as:
a^2 + b^2 = c^2
Plugging in the given values, we get:
5^2 + 15^2 = (√250)^2
Simplifying the left-hand side, we get:
25 + 225 = 250
This is not true, since 25 + 225 = 250 does not hold. Therefore, the given lengths cannot form the sides of a right triangle.
In fact, we can see that the given lengths violate the triangle inequality, which states that the sum of any two sides of a triangle must be greater than the third side. In this case, 5 + 15 = 20 is not greater than √250, so a triangle with these side lengths cannot exist.

The mass of the individual can be up to 87.27 kg for the hot-weather training strategy to be appropriate.
How do you solve for the mass of of the individual using the equation provided?Given that the training strategy is appropriate for a BSA less than 2.0, we need to find the maximum mass (M) for the individual with a height (H) of 165 cm. The equation for BSA is:
BSA = √(H x M) / 3600
We can rearrange the equation to solve for M:
M = (BSA^2 x 3600) / H
Since we want the maximum mass for a BSA less than 2.0, we can use BSA = 2.0 as the upper limit:
M = (2.0^2 x 3600) / 165

Theories have been developed about the heights of winning candidates for the US presidency and the heights of candidates who were runners-up. Listed in the table are heights from recent presidential elections. Find the correlation coefficient and the corresponding critical values assuming a 0.05 level of significance. Is there a linear correlation between the heights of candidates who won and the heights of candidates who were runners-up?
There is a significant linear correlation (r=0.80) between the heights of winning candidates and runners-up in recent US presidential elections.
Using the data from the table, here are the steps to determine the correlation coefficient and test for a linear correlation:
Calculate the correlation coefficient (r) using the formula: r = (nΣXY - ΣXΣY) / sqrt[(nΣX² - (ΣX)²)(nΣY² - (ΣY)²)], where n is the sample size, X and Y are the two variables (heights of candidates who won and runners-up), Σ denotes the sum of the values, and sqrt is the square root function.
Using a spreadsheet, we get r = 0.80.
Using the formula: df = n - 2.
The sample size (n) is 10, so df = 10 - 2 = 8.
Find the critical values of r using a table or calculator based on the degrees of freedom and the desired level of significance (0.05).
For a two-tailed test with df = 8 and α = 0.05, the critical values are ±0.632.
Since |0.80| > 0.632, we can conclude that there is a significant linear correlation between the heights of winning candidates and runners-up.
Therefore, the correlation coefficient is 0.80, and the critical values are ±0.632. There is a significant linear correlation between the heights of winning candidates and runners-up in recent presidential elections.

Answer:
Step-by-step explanation:
To find the LCM of the given expressions, we need to factor each expression completely and then find the product of the highest powers of all the factors.
ax² - (a² + ab)x + a²b can be factored as:
ax² - (a² + ab)x + a²b = a(x - b)(x - a)
bx² - (b² + bc)x + b²c can be factored as:
bx² - (b² + bc)x + b²c = b(x - c)(x - b)
cx² - (c² + ac)x + c²a can be factored as:
cx² - (c² + ac)x + c²a = c(x - a)(x - c)
Now, the LCM is the product of the highest powers of all the factors.
The highest power of a is a², the highest power of b is b², and the highest power of c is c². So, the LCM is:
LCM = a²b²c²(x - a)(x - b)(x - c)
Therefore, the LCM of ax² - (a² + ab)x + a²b, bx² - (b² + bc)x + b²c and cx² - (c² + ac)x + c²a is a²b²c²(x - a)(x - b)(x - c).

You want to know which set of equations could be combined in such a way as to result in the equation 3x = 18.
Set 14x +y = 20x -y = 2To obtain a term of 3x, the second equation must be subtracted from the first. That will result in 3x +2y = 18, not the equation of interest.
Set 2x +y = 4x -2y = 10A term of 3x can be obtained by adding twice the first equation to the second:
2(x +y) +(x -2y) = 2(4) +(10)
3x = 18 . . . . . as required
Set 32x +y = 24-x -y = 6A term of 3x can be obtained by subtracting the second equation from the first. That will result in 3x +2y = 18, not the equation of interest.

In this case, the diameter of the base of the cone is 8 cm, which means the radius is half of that, or 4 cm. The height of the cone is given as 10 cm. Substituting these values into the formula, we get:
V = (1/3)π(4 cm)^2(10 cm)
V ≈ 167.55 cubic centimeters
Therefore, the volume of the paper drinking cone is closest to 167.55 cubic centimeters.
