EXPLANATION
We determine the slope of each line using the slope formula;
The slope of BC is
The slope of AB is
The two lines are perpendicular so the product of their slopes is -1.
This implies that,
.
Hello!
The average mean (arithmetic mean) of all the multiples of ten from 10 to 190 inclusive would be C. 100.
Explanation:
10 and 190 inclusive would mean that there are 19 terms.
To find the arithmetic mean, we must add all the numbers and divide by the amount of numbers.
If you add up all the terms, you will get 1,900. Now, divide that by the number of terms.
1,900 ÷ 19 = 100
Therefore, your answer is C. 100.
Have a wonderful day!
-20 is the answer. Your welcome I might have gotten it wrong but at leAst I tried
3. (x + 1)/4 = 3 / 6
x + 1 = 3/6 x 4 = 2
x = 1
Scale factor = 6 / 4 = 1.5
Ratio of perimeters = 2 : 3
4. x / 21 = 20 / 15
x = 20 / 15 x 21 = 28
Scale factor = 20 / 15 = 4/3
Ratio of perimeters = 3 : 4
