Hey there!
First, let's look at what perpendicular means. Imagine a cross, where there's all 90 degree angles. That's exactly what we're talking about when we say perpendicular. The given equation is in slope-intercept form, where we have:
y = mx + b
where m is the slope and b is the y-intercept.
When we're writing an equation with a perpendicular slope, we use the negative reciprocal of the given slope. Thus, we can make 0.3 1/3, and take the reciprocal to make 3, and make it negative 3 as it's the negative reciprocal. Now, we know we have a line with the slope of -3 and goes through (-3, 8). We can use the x and y values in this set of points, along with the slope, to create an equation to solve for b. That gives us:
8 = -3(-3) + b
8 = -9 + b
17 = b
Now, since we have slope and y-intercept, we can write our equation as:
y = -3x + 17
Hope this helps!
Answer: $62.25
Step-by-step explanation:
The mark-up is $477.25 - 415 = $62.25
1x100,000 = 100,000
3x10,000 = 30,000
9x1,000 = 9,000
8x100 = 800
5x10 = 50
2x1 = 2
Add these all together to get your answer. Standard form is the form we usual write numbers in.
8/100x25=2
2+8=10
10/100x40=4
4+10=14
14-8=6
6/8=0.75
175%

just divide 20/5 and that equal 4. so to find the height of the man you divide 21 by 4
