Answer:
Step-by-step explanation:
The answer is circumference
The formula for interior angle sum is 180(n - 2).
Backtrack it from that.
180(n - 2) = 1980.
1980 / 180 = 11 = n - 2.
11 + 2 = 13 = n.
The polygon has 13 sides.
An integer is a whole number. Sum means to add and since they are consecutive, there is only a difference of 1 between them.
1) 21 + 23: not consecutive
2) 23+24= 47: has to be at least 46
3) 22+23= 45: has to be at least 46
4) 24+25= 49: has to be at least 46
So we have two possibilities: either #2 or #4. Find least possible pair of integers.
x= first integer
x+1= second integer
x + (x+1) >= 46
2x + 1 >=46
2x>=45
x>=22.5
Answer:
The first integer has to be greater than or equal to 22.5. Since integers are whole numbers, round up to the next whole number. The least possible integers are #2) 23 and 24.
Hope this helps! :)
Given
A salad dressing recipe requires at least 8 ounces of oil to be combined with some combination of vinegar and lemon juice in a 16-ounce container.
Find the inequality of this problem
To proof
As given
A salad dressing recipe requires at least ounces of oil = 8 ounces
let us assume that the at least 8 ounces of oil to be combined with some combination of vinegar and lemon juice be x.
Total container capacity = 16-ounce
than the equation is
8 + x ≤ 16
x ≤ 8
i.e some combination of vinegar and lemon juice be 8 ounces.
when at least 8 ounces of oil to be combined with some combination of vinegar and lemon juice.
Hence proved
