Simple Interest = (Principal x Rate x Time)

where:

Principal = R500 (the amount invested)

Rate = 12% per annum = 0.12 (expressed as a decimal)

Time = 4 years

So, the simple interest earned by John over 4 years is:

Simple Interest = (500 x 0.12 x 4) = R240

To find the total amount of money John will have at the end of 4 years, we need to add the simple interest to the principal:

Total amount = Principal + Simple Interest = 500 + 240 = R740

Therefore, John will have R740 at the end of 4 years.

Answer:

The total amount he has at the end is ₹740.

Step-by-step explanation:

Simple Interest = [tex]\frac{PRT}{100}[/tex]

                          =  [tex]\frac{500 * 12 * 4}{100}[/tex] = ₹240

Total amount he has at the end of 4 years = Principal + Interest
                                                                       = ₹500 + ₹240

                                                                       = ₹740

An effective indicator for assessing retail store efficiency, spotting market trends, and making strategic business decisions is annual earnings per employee for profits.

The retail sales industry's annual profits per employee are shown in the data. The data's mean or median is most likely about $4,000,000, according to the assumption. You may compare the productivity of several retail stores by looking at the annual profits per employee. Businesses that generate more annual earnings per employee are typically more productive than those that do not.

The information can also be utilized to spot patterns in the retail sector, such as which businesses are operating better than others. For instance, if a business has been steadily increasing its annual profit per employee, it can be a sign that it is growing or streamlining its operations. In contrast, a business with declining annual profits per employee might be having trouble or seeing a drop in the demand for its goods.

If a painter mixed 56 ounces of blue and yellow paint. The ratio is 3 to 11, 12 ounces of blue paint were utilized by the painter.

To solve the problem, we can use the ratio of blue to the total amount of paint to determine how many ounces of blue paint were used. The ratio of blue to the total paint is 3 to 11. This means that for every 3 parts of blue paint, there are 11 parts of total paint. We can use this information to set up a proportion:

3/14 = x/56

Where x represents the number of ounces of blue paint used. To solve for x, we can cross-multiply and simplify:

356 = 14x

168 = 14 × x

x = 12

Therefore, the painter used 12 ounces of blue paint.

Answer:

  80°

Step-by-step explanation:

You want the larger of two acute angles in a right triangle if their relationship is cos(8x°) = sin(2x-10°).

The cosine of an acute angle is equal to the sine of its complement. The given relation between the angles means ...

  (8x) +(2x -10) = 90 . . . . . the angles are complementary

  10x = 100 . . . . . . . . . . . add 10

  x = 10 . . . . . . . . . . . . . divide by 10

The two angles are 8·10° = 80° and (2·10 -10)° = 10°.

The larger of the two acute angles is 80°.

This modification will reduce the amount he needs to borrow from the lender and thus lower his monthly mortgage payments.

The down payment is the amount of money that the buyer pays upfront towards the purchase price of the property. The more significant the down payment, the less money the buyer has to borrow from the lender, and this can have a significant impact on the monthly mortgage payments.

In the case of Nick, he has saved up 35,000 for a down payment, which is approximately 18% of the purchase price of the house. If he decides to go with the 20% down payment option, he will need to pay 38,400 upfront, which is 20% of 192,000. The remaining 153,600 will be the amount he borrows from the lender.

Now, let's assume that Nick has taken a 30-year fixed-rate mortgage at 6.25% interest. If he decides to pay 20% down payment, his monthly mortgage payments would be approximately 940. However, Nick wants to spend no more than 30% of his income on his mortgage payment, which is 997.50 per month (30% of 3,325). Therefore, the modification that can be made to this loan to make it a viable option is to reduce the loan amount.

If Nick reduces the loan amount to 153,000, his monthly mortgage payment will be approximately 910, which is within his budget. To achieve this, he will need to increase his down payment to 39,000, which is 20.3% of the purchase price. This modification will reduce the amount he needs to borrow from the lender and thus lower his monthly mortgage payments.

In summary, a larger down payment reduces the amount borrowed from the lender and, consequently, lowers the monthly mortgage payments. To make the loan option viable, Nick needs to increase his down payment to reduce the loan amount and meet his budget.

Point A is correct.

The required expression represents the value in dollars of the coin n years after Hector found is [tex]$c(n) = 190 \times (1.1)^n$[/tex].

Let's call the percentage increase in value each year "r". We know that after one year, the coin was worth $209, which is 209/190 = 1.1 times what it was worth when Hector found it. So we can set up an equation:

[tex]$190 \times (1 + r)^1 = 209$[/tex]

Simplifying this equation,

[tex]$1 + r = \sqrt[1]{\frac{209}{190}}$[/tex]

1 + r = 1.1

r = 0.1

So the percentage increase in value each year is 10%. To find the value of the coin "n" years after Hector found it, we can use the formula:

[tex]$c(n) = 190 \times (1 + r)^n$[/tex]

Substituting the value we found for "r", we get:

[tex]$c(n) = 190 \times (1.1)^n$[/tex]

So the expression for the value of the coin "n" years after Hector found it is:

[tex]$c(n) = 190 \times (1.1)^n$[/tex]

Thus, required expression represents the value in dollars of the coin n years after Hector found is [tex]$c(n) = 190 \times (1.1)^n$[/tex].

The domain of function f is (-∞, 10) U (10, ∞) or {x|x ≠ 10}.

The range of function f is (-∞, -3) U (-3, ∞) or {y|y ≠ 3}.

The inverse of this function is f⁻¹ = (10x - 4)/(3 + x).

The domain of function f⁻¹ is (-∞, -3) U (-3, ∞) or {x|x ≠ 3}.

The range of function f⁻¹ is (-∞, 10) U (10, ∞) or {y|y ≠ 10}.

In Mathematics, an inverse function simply refers to a type of function that is obtained by reversing the mathematical operation in a given function (f(x)).

In order to determine the inverse of any function, you should swap both the input value (x-value) and output value (y-value) as follows;

f(x) = y = (3x + 4)/(10 - x)

x = (3y + 4)/(10 - y)

10x - yx = 3y + 4

3y + yx = 10x - 4

C (bottom of column)

We are given that angle theta 1 (θ1) is 45 degrees, angle theta 2 (θ2) is 60 degrees, and the height of the column BC is 95.62 meters. We want to find the height of the house AB, which we'll call "h".

First, we can use trigonometry to find the length of segment CD. Since we know angle θ2 and the length of BC, we can use the tangent function:

tan(θ2) = opposite / adjacent

tan(60°) = d / 95.62

d = 95.62 * tan(60°)

d ≈ 165.30 meters

Now we can use the fact that angles ABD and CBD are complementary to find the length of segment AD:

tan(θ1) = opposite / adjacent

tan(45°) = h / (d + 165.30)

h = (d + 165.30) * tan(45°)

h ≈ 165.30 meters

Therefore, the height of the house is approximately 165.30 meters.

Step-by-step explanation:

The cup will hold more ice cream than cone since volume of cup is 169.6 cubic inches which is greater than volume of 25.1 cubic inches.

The volume of a cone is given by the formula:

V= 1/3.π[tex]r^{2}[/tex]h

where r is the radius of the circular base and h is the height.

The volume of a cylinder is given by the formula:

V= π[tex]r^{2}[/tex]h

where r is the radius of the circular base and h is the height.

Assuming that the height of both the cone and the cup is the same, we can compare their volumes by comparing their radii.

For the cone, the radius r is equal to half the diameter of the circular base, which is equal to w/2 = 2 in.

The height of the cone is equal to y, which is 6 in.

V= 1/3.π[tex]r^{2}[/tex]h= 1/3.π[tex]2^{2}[/tex]6

For the cup, the radius r is equal to x/2 = 3

The height of the cup is equal to y, which is also 6 in.

Using these values, we can calculate the volume of the cup as:

[tex]V_cup[/tex]= π[tex]r^{2}[/tex]h=π[tex]3^{2}[/tex]6

Therefore, the cup will hold more ice cream than the cone.
