A box had twice as many grapes as a basket. Once 2 kg of grapes were added to the basket, it contained 0.5 kg more than the box.
guapka [62]

Answer:

3.5kg

Step-by-step explanation:

Let original weight  of grapes in box be X and weight of grapes in basket be Y.

From the first sentence
X = 2Y  (weight in box = 2 times weight in basket)   --- (1)

If you add 2kg of grapes to basket, the weight of grapes in basket = Y + 2

From the second statement

Y + 2 = X + 0.5

Subtracting Y from the LHS gives 2 = X - Y + 0.5

Subtracting 0.5 from both sides gives 2-0.5 = X - Y or X - Y = 1.5  --- (2)

Substituting for X from the first equation in (2) we get
2Y - Y = 1.5 or Y = 1.5kg

But this is the original weight of the grapes in the basket. Since we have added 2 kg of grapes to the original weight, we get the weight of grapes in basket now as 1.5 + 2.0 = 3.5kg

Find the sum of the first six terms of a geometric progression .​
Dominik [7]

Question:

Find the sum of the first six terms of a geometric progression.

1,3,9,....

Answer:

S_6 = 364

Step-by-step explanation:

For a geometric progression, the sum of n terms is:

S_n = \frac{a(r^n - 1)}{r - 1}

In the given sequence:

a = 1

r = 3/1 =3

n = 6

So:

S_n = \frac{a(r^n - 1)}{r - 1}

S_6 = \frac{1 * (3^6 - 1)}{3 - 1}

S_6 = \frac{3^6 - 1}{2}

S_6 = \frac{728}{2}

S_6 = 364
