Three investors own a company. One partner owns 1/4 of the company , while the second partner owns 2/5 of the company . How much

Yakvenalex [24]

We want to add these together and then subtract from one. So to add them, find a common denominator.
The closest common denominator is 20.
So convert the fractions:
5/20 and 8/20
Then add
5/20 + 8/20 = 13/20
And then subtract from 1.
1 - 13/20 = 7/20
The third partner owns 7/20 of the company.

Topic: Finite Geometric Sums what is the value of ..

Juli2301 [7.4K]

For i=1 ===> Sum=4

for i=2===> Sum=2

for I=3===> Sum=1

Hence the answer is 7

Or you could have use the Sum formula of a GP:

Sum = a(1-r)^n/(1-r), with a=1, r=1/2 & n=3

(sum by gcf ) what is the gcf of 44+40? 44+40=4 (__+__)

Illusion [34]

The answer is 4

|________ you put 44+40 in the box

|_______ then you see what goes into both and it is 4 so then divide 44 and 40 by 4

then put 11+10 in the box and nothing goes into 11 and 10 so 4 is the only thing that goes into 44 +40

Use a calculator to find the approximate value of arccos(0.67). 42.07° 33.82° 84.13° 47.93°

Solnce55 [7]

Arccos is the same thing as inverse cosine which is used when you are looking for an angle measure. Make sure your calculator is in degree mode. Hit 2nd button then cos and you will see this on your screen: $cos ^{-1} ($ and it is following the parenthesis there that you will enter your decimal. The inverse cosine of .67 is an angle measure of 47.93°
