Correct Answer: D. legislature

Correct Answer: A. Mubaraah

Correct Answer: (c) 14

Explanation

To find the length of the greatest side of the triangle, follow these steps:

1. Set up the equation using the given ratio:

Let the lengths of the sides of the triangle be 3x, 5x, and 7x.

2. Use the perimeter to solve for x:

Perimeter = 3x + 5x + 7x = 30 cm

15x = 30

x = \frac{30}{15} = 2

3. Find the length of the greatest side:

The greatest side corresponds to the largest ratio value, which is 7x:

Greatest side = 7 \times 2 = 14 cm

Therefore, the correct option is (c) 14.

Explanation

The main decisions of the General Conference of 1950 in Ibadan are:

(i) The 1946 Richards Constitution did not provide any power for the regional councils. This conference gave limited legislative powers to the regions.

Correct Answer: D. river ports

Correct Answer: C. 3%

Explanation

Let N_0 be the initial number of nuclei.

Let N be the number of nuclei remaining after a certain time t.

Let T be the half-life of the radioactive substance.

The number of half-lives (n) is given by n = t / T.

The formula for the fraction of nuclei remaining after 'n' half-lives is:

N / N_0 = (1/2)^n

In this problem, the number of half-lives is given as 5. So, n = 5.

Substitute n = 5 into the formula:

N / N_0 = (1/2)^5

Calculate (1/2)^5:

(1/2)^5 = 1 / (2 * 2 * 2 * 2 * 2)

= 1 / 32

To express this as a percentage, multiply by 100%:

Percentage remaining = (1/32) * 100%

= 100 / 32 %

= 25 / 8 %

= 3.125 %

Now, let's compare this result with the given options:

A. 8%

B. 5%

C. 3%

D. 1%

The calculated percentage is 3.125%. The closest option is 3%.

The final answer is 3%.

Correct Answer: C. 35

Explanation

?(E?G) = ?(E) + ?(G) - ?(E?G)

80 = 65 + 50 - ?(F?G)

??(E?G) = 115 - 80 = 35

Correct Answer: B. 7.92 x 10⁶W
