8.77 x 10^1 i believe but would double check
Since you need to find the area of a square napkin, you need to know what the formula for a square is. It is height multiplied by base. So a square is equal in all sides. 8×8=64
Answer: 64 in²
Answer:
Option C.
Step-by-step explanation:
Shortest way to solve this question is to find the factors of the given expression.
The given expression is (x² + 13).
Now we have to factorize it.
(x² + 13) = x² + (√13)²
= x² + [-(i)²√(13)²] [Since i = √(-1)]
= x² - (i√13)²
= (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]
Option C will be the answer.
Answer:
7%
Step-by-step explanation:
Using the formula
Amount = Principal + Interest
Give the following
Principal = ₹ 5000
Amount =₹ 6050
Time = 3 years
Required
Time
Substitute into the formula
A = P + I
A = P + PRT/100
6050 = 5000 + 5000(R)(3)/100
6050 - 5000 = 150R
1050 = 150R
R = 1050/150
R = 7
Hence the rate of interest is 7%
