The rule for side lengths of a triangle is that the two lowest lengths sum has to be greater than the longest length. so
a+b>c
For the 1st question
4+3>6
7>6
So yeah, it can be a triangle
For the 2nd one
1+3>4
4>4
So no, it can't be a triangle
Sandy has two possibilities
lengths of 3,3,4
or
lengths of 4,4,3
Answer:
The sum of all the sweets is 54 sweets
Step-by-step explanation:
Here, we want to calculate the number of sweets the three have altogether.
Let the number of sweet Faith has be x
Mathematically;
Faith has 4 sweets fewer than the average number of sweets
The average is the sum of all the sweets divided by 3
The average will be (10 + 30 + x)/3
Thus;
(10 + 30 + x)/3 - 4 = x
(40 + x)/3 = x + 4
40 + x = 3(x + 4)
40 + x = 3x + 12
40-12 = 3x -x
28 = 2x
x = 28/2
x = 14 sweets
So the sum of all the sweets would be 10 + 30 + 14 = 54 sweets
Well since 27% in decimal form is .27, that mean .48 is greater.
27% < 0.48
