A centroid in a triangle, is the point where all the medians meet.
now a peculiar thing about the centroid is that, it cuts all medians in a 2:1 ratio.
so, if that's true, then the median AE, is being cut in two segments AD and DE and AD : DE are on a 2 : 1 ratio, are they? let's check.
Answer:
Rate is 8.5%
Step-by-step explanation:
Step 1: Write the given terms
Principal (p)=Rs8800
Rate(r)=?
Time(t)=3.5 years
Interest=Rs2618
Step 2: Write the formula for calculating Simple interest
![i = \frac{prt}{100}](https://tex.z-dn.net/?f=i%20%3D%20%5Cfrac%7Bprt%7D%7B100%7D%20)
Step 3: Make r the subject of the equation
![by \: cross \: multiplication \\ 100i = prt \\ divide \: both \: sides \: by \: pt \\ r = \frac{100i}{pt}](https://tex.z-dn.net/?f=by%20%5C%3A%20cross%20%5C%3A%20multiplication%20%5C%5C%20100i%20%3D%20prt%20%5C%5C%20divide%20%5C%3A%20both%20%5C%3A%20sides%20%5C%3A%20by%20%5C%3A%20pt%20%5C%5C%20r%20%3D%20%20%5Cfrac%7B100i%7D%7Bpt%7D%20)
Step 4: Find the value of r by substituting the values in step 1
![r = \frac{100 \times 2618}{8800 \times 3.5} \\ r = \frac{261800}{30800} \\ r = 8.5](https://tex.z-dn.net/?f=r%20%3D%20%20%20%5Cfrac%7B100%20%5Ctimes%202618%7D%7B8800%20%5Ctimes%203.5%7D%20%20%5C%5C%20r%20%3D%20%20%5Cfrac%7B261800%7D%7B30800%7D%20%20%5C%5C%20r%20%3D%208.5)
Hence, the rate is 8.5%
Answer:
Equation 1 would be: 3a+2C
Equation 2 would be: 5a+3C
Step-by-step explanation:
$751,150 -6.8%*751,150 -657,900 -24,500 = $17,671.80
Their net profit is $17,671.80.
