Try to multiply if its not there then divide.
There are several important information's already given in the question. Based on those given information's the answer to the question can be easily deduced.
Total number of students in the school = 209
Ration of the boys to girls in the school = 6:5
Let us assume the common ratio to be = x
Then
6x + 5x = 209
11x = 209
x = 209/11
= 19
Then
The number of girls in the school = 19 * 5
= 95
So there are a total of 95 girls in the school that has a total of 209 students.

f(x) = x³ - 8x² + 22x - 20
given x = a, x = b are zeros of a polynomial then
(x - a) and (x - b) are factors and the polynomial is the product of the factors
f(x) = k(x - a)(x - b) → ( k is a multiplier )
note that complex zeros occur in conjugate pairs
3 + 1 is a zero then 3 - i is a zero
zeros are x = 2, x = 3 + i and x = 3 - i, thus
(x - 2 ),(x - (3 + i )) and (x - (3 - i )) are the factors
f(x) = (x - 2)(x - 3 - i )(x - 3 + i)
= (x - 2)(x² - 6x + 10)
= x³ - 8x² + 22x - 20
If you’re looking for the volume of a sphere, it is
V = 4/3πr³
Answer:
The answer is ∠C= 20 degree
Step-by-step explanation:
The answer is ∠C= 20 degree
We have given:
AB= 5
AC = 14
and we have to find ∠c to the nearest degree.
So,
We know that:
tan(C)= AB/AC
tan(C)= 5/14
tan(C)= 0.3571
C=20 degree
Thus the answer is ∠C = 20 degree ....
