You can’t really show work for this problem, but the answer is A. This is because physics is about motion, energy, force and stuff and when you get in to a wreck, there are forces and stuff lol
Answer:
The mark up is $21.16 and the final selling price is $44.14
Step-by-step explanation:
To find the mark up price, you simply multiply the cost by the mark up percentage. This will give you the mark up.
$23 * 92% = $21.16
Now to find the total selling price, we add the cost and the mark up together.
$23 + $21.16 = $44.16
First, you want to find the slope of the line. You do this by taking the difference in the heights divided by the difference of the time.
m=(20-12)/(5-3)
m=8/2
m=4
Now plug the information into slope intercept form (you can choose whichever set of data you want, just as long as you are consistent):
y=mx+b
12=(4)(3)+b
12=12+b
b=0
This is saying that there is no y-intercept (b).
So our final equation is:
y=4x
The question is asking for y when x is 1, so just plug it into the equation:
y=4(1)
y=4
Hope this helps!
a) Parallel for both line segments have the same slope = -5/4
b) 55º
Step-by-step explanation:
a) To verify the parallelism of these line segments, It's necessary to find the slope of each one. Parallel lines share the same slope value:
b) If ∠DAB = 125°, what is the measure of ∠CBA? Justify your reasoning.
Those beams do not form a parallelogram because:
Using the formula of distance between those points
So this is a trapezoid. And two adjacent angles within a trapezoid are supplementary, so If ∠DAB = 125º then 180 - ∠CBA=55º
