To turn a percent into a fraction you just put the number over 100 and then simplify
Answer:
8/5 or 1.6
Step-by-step explanation:
Rise over run.
Answer:
-9x + 5
Step-by-step explanation:
Slope Intercept Form = y = mx + b
where x = slope and b = y intercept
We are told that the slope is -9 and the y intercept is at (0,5)
So x = -9 and b = 5
that being said we plug in the values into the equation
Therefore y = -9x + 5 is your answer
Answer:
the answer is 30
Step-by-step explanation:
Let the number be x
- 3 (x - 12) = - 54
-3x + 36 = -54
-3x = -54 - 36
-3x = -90
x = -90/-3
x = 30
There are two ways you could go about solving this.
You could divide the length of the base (6mm) by 2 and use that to find the area or you could find the area of the whole triangle using 6mm and divide that by 2.
I will use the first method I described:
base = 6/2
base = 3 mm
height = 5.2 mm
area = bh/2
area = (3 * 5.2)/2
area = 7.8 square mm
(don't forget your units)
Using the other method would look like this:
area = bh/2
b = 6
h = 5.2
area = (6 * 5.2)/2
area = 15.6 square mm
area/2 = 7.8 square mm
As you can see either method yields the same result.
Hope this helped.
Cheers and good luck,
Brian
