Step-by-step explanation:
For this problem, we can simply plug in the coordinate point into the given formula.
(-8, 6) = (-8 + 5, 6 - 4)
(-8, 6) = (-3, 2)
So, A' is at point (-3, 2)
Now, we have to find the distance from A to A'. We can use the distance formula.
So, the distance between A and A' is about 6.4 units.
Answer:
In a class of 28 students the ratio of girls and boys is 4:3. The number of girls in the class is 16.
Solution:
Let us consider total number of students in the class is “T”.
Let the ratio of the students (Girl and boys) in the class is G: B.
Given that total number of students in class (T) = 28
From question, given that ratio of girls and boys is 4:3. We can write this ratio as,
Number of girls (G) = 4x and number of boys (B) = 3x
We have to find the number of girls in class. The total number of girls present in the class is given as ,
The total girl students present in the class G =
=
Hence the total number of girls in the class is 16.
