What is the length of the line segment in the x-y plane with end points at (-2,-2) and (2,3)?
Ber [7]
You've got a formula. If the two endpoints are A(x_A,y_A) and A(x_B,y_B), then the length is \sqrt{(x_B-x_A)^2+(y_B-y_A)^2}. The result is \sqrt{16+25}=\sqrt{41}.

Answer:

Rs 600,000

Step-by-step explanation:

Let the original amount be X

Amount given to daughter = (1/2) X = X/2

Amount given to son = (1/3) X = X/3

donation = Rs 100,000

Total amount = Amount Given to Daughter + Amount given to Son + Donation

X = X/2 + X/3 + 100,000   (solve for X)

X = (5/6)X +  100,000

X - (5/6)X  =   100,000

(1/6)X  =   100,000

X = (6) (100,000)

x = Rs 600,000

8-inch boxes are stacked next to 6-inch boxes. What is the lowest height at which the two stacks will be the same height?​
Vladimir79 [104]

Answer:

<u>The lowest height at which the two stacks will be the same height is 24 inches.</u>

Step-by-step explanation:

For answering this problem, we have to find out the lowest common multiple of 6 and 8, listing its prime factors, this way:

6 = 3 * 2

8 = 2 * 2 * 2

Now, we multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

Therefore, we have:

2 : 3 times as prime factor of 8

3: 1 time as prime factor of 6

The lowest common multiple is:

2 * 2 * 2 * 3 = 24

<u>The lowest height at which the two stacks will be the same height is 24 inches.</u>
