Step-by-step explanation:
Given 2 similar figures with ratio of corresponding sides = a : b
Then the ratio of the perimeter is also = a : b
and ratio of areas = a² : b²
Here ratio of sides = 2 : 5, thus
ratio of perimeters = 2 : 5 and
ratio of area = 2² : 5² = 4 : 25
Answer:
Step-by-step explanation:
42-42(2/7)
42-12
30
There are 30 options with no chocolate.
F(n) = 5x -7
Explanation: use y2-y1/x2-x1 to find the slope.
You’ll write it like -12-3/-1-2 = -15/-3 = 5
slope = 5
To work out 10% you divide it by then. 10% of 30 is 3. To get 80% from 10%, you times it by 8. 3X8=24
