Answer:
5.88%
Step-by-step explanation:
18 - 17 / 17
1/17 = 0.0588
= 5.88%
Yes, it is Proportional.
Y=0.25x
For example:
If x=1, y=0.25
If x=2, y=0.5
So, it is proportional.
Using Estimation, by rounding 21 down to 20 and 88 up to 90, answer A would be the correct option.
Answer: -1/2
Step-by-step explanation:
slope is you know rise over run
which means the equation would look like 
, but since there's no graph and line showed up and only have two points given, you should subtract second point and first point (the order doesn't really matter tho), then 
, so
<span>are you familiar with the pythagorean theorem?
</span>it's the formula
a^2 + b^2 = c^2
where 'a' and 'b' are the legs of a right triangle, c is the hypotenuse
so here,
<span>lets take
a = unknown, b = 18, c = 36</span><span>If we focus on triangle ABC, we see that AC is the hypotenuse
If we turn our attention to triangle ADB, we'll find that AB is the hypotenuse
So they are corresponding partAD is the longer leg of triangle ADB
AB is the longer leg of triangle ABC
so this is another pair of corresponding partswe then divide the corresponding parts of ABC over ADB (in the same order) like this
AC/AB = AB/AD
then plug in the info we know
36/(18*sqrt(3)) = (18*sqrt(3))/AD
and then solve for ADcross multiply to get
36*AD = (18*sqrt(3))(18*sqrt(3))
36*AD = 18*18*sqrt(3)*sqrt(3)
36*AD = 18^2*(sqrt(3))^2
36*AD = 324*3
36*AD = 972 AD = 972/36AD = 27hope u get it :)</span>
