Explanation

I=P×R×T

Principal amount (P) = 60,000

Rate of interest (R) = 9% per year

Time (T) = 3 years

Simple interest (SI) = (P x R x T) / 100

= (60,000 x 9 x 3) / 100

= 16,200

The total amount he repaid after 3 years is:

Principal + Interest = 60,000 + 16,200 = 76,200

Explanation

To calculate David's average marks, we need to add up all his marks and divide by the number of subjects:

English: 76

Mathematics: 65

Physics: 82

Chemistry: 67

Biology: 85

Total marks: 76 + 65 + 82 + 67 + 85 = 375

Number of subjects: 5

Average marks: 375 ÷ 5 = 75

So, David's average marks are: 75

Explanation

V = (4/3)πr³

6400 = (4/3)πr³

To solve for r, we can rearrange the formula:

r³ = 6400 x (3/4) / π

r³ = 4800 / π

r = ∛(4800/π)

r ≈ 11.52

So, the radius of the basketball is approximately: 11.52 cm

Explanation

Let's calculate the new length and width of the picture:

Original length (L) = 9 cm

Original width (W) = 5.5 cm

Enlargement ratio = 7:5

New length (L') = (7/5) × L = (7/5) × 9 = 12.6 cm

New width (W') = (7/5) × W = (7/5) × 5.5 = 7.7 cm

So, the new length and width of the picture are:

7.7 cm by 12.6 cm

Explanation

The mean of 5 numbers is 34, so the sum of these 5 numbers is:

5 x 34 = 170

We know three of the numbers: 29, 26, and 35. Let's add them up:

29 + 26 + 35 = 90

Now, we need to find the sum of the remaining two numbers:

170 (total sum) - 90 (sum of known numbers) = 80

Since the remaining two numbers are in the ratio 1:3, let's assume the smaller number is x. Then, the larger number is 3x.

We know their sum is 80, so we can set up the equation:

x + 3x = 80

Combine like terms:

4x = 80

Divide by 4:

x = 20

Now that we know x, we can find the larger number:

3x = 3(20) = 60

So, the remaining two numbers are 20 and 60.

Explanation

MS PowerPoint is a software specifically designed for creating presentations.

It allows users to communicate ideas visually through slides, images, and animations.

Explanation

When applying conditional formatting in spreadsheet software like Microsoft Excel, Google Sheets, or LibreOffice Calc, you can check conditions against:

• Cell value: You can specify a condition based on the value in a cell, such as "greater than", "less than", "equal to", etc.
• Formula: You can also specify a condition based on a formula, which can include references to other cells, functions, and operators.
