(a) 2, 5, 10, 17, 26, …….

(b) 4, 10, 20, 34, 52, ………

Part of a geometric sequence is given below:

,,,,, -1, ,,,, , ,,,,,, 64, ,,,,,

Tanner is picking three varieties of apples at an orchard: Gala, Fuji, and Jazz. Each type of apple has a different cost per pound. He knows that 1 pound of each apple variety would cost a total of $5.16, and that the cost per pound of Jazz apples is the same as the combined cost per pound of the Gala and Fuji apples. Tanner picks 12 pounds of apples, including 3 pounds of Gala and 5 pounds of Fuji, for a total cost of $21.24.


If g represents the cost per pound of Gala apples, f the cost per pound of Fuji apples, and j the cost per pound of Jazz apples, which system of equations represents this situation?

Answers

Answer:

2g + 2f = 5.16

7g + 9f = 21.24

Step-by-step explanation:

Let

Gala = g ; Fuji = f ; jazz = j

g + f + j = 5.16 - - - (1)

j = g + f - - - (2)

From (1):

g + f + g + f = 5.16

2g + 2f = 5.16 - - - (3)

Total pound picked by Tanner = 12

3 Pounds of g ; 5 pounds of f

j = 12 - (5 +3) = 4 pounds

3g + 5f + 4j = 21.24 - - - (4)

3g + 5f + 4(g + f) = 21.24

3g + 5f + 4g + 4f = 21.24

7g + 9f = 21.24 - - - - - (5)

this should be the answer for this question!

Maria's Grocery Store buys grapefruit at a cost

of 5 for a dollar. They sell them at a price of 5

for three dollars. How many must they sell in

order to make a profit of ten dollars?

Answers

Answer: 25 grapefruits

Step-by-step explanation:

They buy grapefruit at a price of 5 per dollar. This means that the price per grapefruit is:

= 1 / 5

= $0.20 per grapefruit.

They then sell at a price of 5 per $3. The selling price per grapefruit is:

= 3 / 5

= $0.60

The profit per grapefruit is:

= 0.60 - 0.20

= $0.40

In order to make a profit of $10, they should sell:

= 10 / 0.4

= 25 grapefruits

Answer:

10th term of the sequence = 0.537

Step-by-step explanation:

First three terms of the sequence are → 5, 4, [tex]\frac{16}{5}[/tex]..........

Ratio of 2nd and 1st term of the sequence = [tex]\frac{4}{5}[/tex]

Ratio of 3rd and 2nd term of the sequence = [tex]\frac{\frac{16}{5} }{4}[/tex]

                                                                        = [tex]\frac{4}{5}[/tex]

Therefore, ratio between every successive term to the previous term is common.

Common ratio 'r' = [tex]\frac{4}{5}[/tex]

First term of the sequence 'a' = 5

nth term of a geometric sequence = [tex]a(r)^n[/tex]

Therefore, nth term of the given term will be  [tex]T_n=5(\frac{4}{5})^n[/tex]

Now we have to find the 10 term of the given sequence.

For n = 10,

[tex]T_{10}=5(\frac{4}{5})^{10}[/tex]

      = 0.53687

      ≈ 0.537

Therefore, 10th term of the sequence is 0.537
