Answer:
The length of each sides are 11 feet, 16.5 feet, 27.5 feet.
Step-by-step explanation:
The ratio of the sides of a triangle are 2:3:5.
The sides of the triangle = 2x, 3x, 5x
The perimeter of the triangle = 55 feet.
2x + 3x + 5x = 55
10x = 55
x = 55/10 = 5.5
Length of each side : 2x = 2*5.5 = 11 feet
3x = 3*5.5 = 16.5 feet
5x = 5 * 5.5 = 27.5 feet
5/8
The sectors are labeled 1,2,3,4,5,6,7,8
Numbers less than 4: 1,2,3
Multiples of 4: 4,8
We are looking for 1,2,3,4,8 = 5 choices
P (1,2,3,4,8) = Number of choices/ total
= 5/8
Total number of ways will be 209
There are 6 boys and 4 girls in a group and 4 children are to be selected.
We have to find the number of ways that 4 children can be selected if at least one boy must be in the group of 4.
So the groups can be arranged as
(1 Boy + 3 girls), (2 Boy + 2 girls), (3 Boys + 1 girl), (4 boys)
Now we will find the combinations in which these arrangements can be done.
1 Boy and 3 girls = =24
2 Boy and 2 girls=
3 Boys and 1 girl =
4 Boys =
Now total number of ways = 24 + 90 + 80 + 15 = 209
Answer: t, and u
edit: 92-17=75
when using range you subtract the highest number with the lowest
