84/70=1.2 so the ratio of g:b must be 1.2:1 but we have to deal with integer amounts so...

1.2:1=6:5   

So you can make (84/6)  14 stacks of 6 green and 5 reds

Find the 10th term of geometric sequence 3,15,75,375
Bess [88]

Answer:


Step-by-step explanation:

In a geometric sequence, the next term is a constant times the previous term. This constant is determined by dividing the second term by the first, here giving 5. The remaining terms are checked to see that each is 5 times the previous. 75 is 15×5, 375 is 75×5.


Alternately, the nth term is first term times k^(n-1).

Here, that's 3×5^(10-1), 3×5^9=5859375

If Will buys 1 kilogram of African rice and 2 kilograms of basmati rice, how much will he spend? brown rice $3.03/kg $3.59/kg st
Alenkasestr [34]

Answer:

Step-by-step explanation:

Sorry, because of lack of punctuation and organization, I cannot determine with any confidence the price per kilo of each of the rices.

He will spend the price of one kg of African rice plus twice the price of Basmati rice.

IF

African rice = $1.69/kg

and

Basmati rice = $3.05/kg

THEN

Cost = 1.69 + 2(3.05) = $7.79

Anna has a 25-meter-long fence that she plans to use to enclose a rectangular garden of width w. The fencing will be placed arou
Leviafan [203]
<h3>Answer:   -2w^2 + 25w = 25    or    -2w^2 + 25w - 25 = 0</h3>

================================================================

Explanation:

Refer to the diagram below. The width is w. We have two opposite and parallel sides equal to this. The other two parallel congruent sides are L = 25-2w meters long. We start with the total amount of fencing, and then subtract off the two width values, so 25-w-w = 25-2w.

The area of the rectangle is

Area = length*width

Area = L*W

Area = (25-2w)*w

Area = 25w - 2w^2

Area = -2w^2 + 25w

Set this equal to the desired area (25 square meters) to get

-2w^2 + 25w = 25

and we can subtract 25 from both sides to get everything on one side

-2w^2 + 25w - 25 = 0

side note: The two approximate solutions of this equation are w = 1.0961 and w = 11.4039 (use the quadratic formula or a graphing calculator to find this)
