Please Note
When the question has the word choice in it, you should list the choices. For this question, it really may not matter. The answer is W + 15 or 15 + W. With other questions as you advance, it will matter.
Step-by-step explanation:
Let's set up a proportion.
345.12/4638.34=x/100.
A percent is always out of one hundred and is the part out of a whole, so to solve for it we must set x equal to the part (345.12) out of the whole (4638.34).
Now if we solve for x it will equal 7.440593, which is kind of a big number. We can round it to the nearest hundredth, 7.44%, or just round it to the nearest percentage 7%.
Given :
A graph .
To Find :
A point C that divides the segment into the ratio AC:AB= 3/4 .
Solution :
From the graph we can see that point A and B are ( 1 , -2 ) and ( 5 , 6 ) respectively .
Now , we know point which divide a line segment with end point
and
in m : n is :
![x=\dfrac{mx_2+nx_1}{m+n}\ ,\ y=\dfrac{my_2+ny_1}{m+n}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7Bmx_2%2Bnx_1%7D%7Bm%2Bn%7D%5C%20%2C%5C%20%20y%3D%5Cdfrac%7Bmy_2%2Bny_1%7D%7Bm%2Bn%7D)
Putting all given values we get :
![x=\dfrac{3(5)+4(1)}{3+4}\ ,\ y=\dfrac{3(6)+4(-2)}{3+4}\\\\x=\dfrac{19}{7}\ ,\ y =\dfrac{10}{7}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B3%285%29%2B4%281%29%7D%7B3%2B4%7D%5C%20%2C%5C%20%20y%3D%5Cdfrac%7B3%286%29%2B4%28-2%29%7D%7B3%2B4%7D%5C%5C%5C%5Cx%3D%5Cdfrac%7B19%7D%7B7%7D%5C%20%2C%5C%20y%20%3D%5Cdfrac%7B10%7D%7B7%7D)
Therefore , point C is
.
Hence , this is the required solution .
4 difference, subtract 20 point - 1st point, =19, 19 places x difference of 4= 76 more or less than 36. More would be 112, less would be -40.
A and C are both 40 while choice B = the difference so I'd say it's supposed to be 1 of the 40's but it's missing the negative sign
