View Answer	Favorite Question

Answer: Option D

Explanation:

find out how many numbers there are in the series, we subtract the first number from the last (15 - 7 = 8), divide the result by the step size (8 / 2 = 4), and then add 1 to account for the first number that we started with. Therefore, there are 5 numbers in this series.

E. None of these

View Answer	Favorite Question

Answer: Option C

Explanation:

given, the annual interest rate decreases from 4% to 3.75%

ATQ,

(4 - 3.75)% = 60

or, 0.25% = 60

or, 100% = (60/0.25) * 100 = 24000

so, principal = 24000 tk

ans: 24000 tk

2010 . If the area of a small pizza is 78.5 in. what size pizza box would best fit the small pizza?

A. 12 in
B. 11 in
C. 9 in
D. 10 in

View Answer	Favorite Question

Answer: Option D

Explanation:

To find the size of the pizza box that would best fit the small pizza, we can use the diameter of the pizza as the size of the pizza box.

The area of a circle is given by the formula: A = πr^2, where "A" is the area and "r" is the radius.

In this case, the area of the small pizza is 78.5 square inches. We can use this information to find the radius of the pizza:

78.5 = πr^2

Now, solve for "r":

r^2 = 78.5 / π r^2 ≈ 25 r ≈ √25 r ≈ 5 inches

So, the radius of the small pizza is approximately 5 inches. To find the diameter (which is also the size of the pizza box needed), simply double the radius:

Diameter = 2 * 5 inches = 10 inches

Therefore, a 10-inch pizza box would best fit the small pizza.
