The 6th term of an arithmetic progression is 35 and the 13th term is 77. find the 20th term

Helga [31]

20th term= 119

Step-by-step explanation:

Let the first term of AP be a

and common difference be d

nth term is given by,

= a+(n-1)d

6th term = 35

a+(6-1)d= 35

a+5d=35 -----------------(i)

13th term = 77

a+12d= 77----------------(ii)

Now, equation (ii) - (i)

a+12d-(a+5d)= 77-35

a+12d-a-5d= 42

7d=42

d=6

Now, from equation (i)

a= 35-5d= 35-5(6)= 35-30 = 5

20th term= a+19d= 5+19(6)= 119

iragen [17]

Answer:

The total number of cartons did he sale is 20 .

Step-by-step explanation:

Given as :

The total number package in each carton = 28

The total amount received after sale = $ 280

The cost of 10 noodles = $ 5

Let the total number of cartoon sale = x

According to question

∵ The number of noodles costing $5 is 10

so,The number of noodles costing $1 is $\frac{10}{5}$ = 2

∴ The number of noodles costing $280 = 2 × 280 = 560

Now, since there are 28 packages in 1 carton

So . the number of carton did he sale = $\dfrac{\textrm total number of noodles}{\textrm total package in each cartoon}$

Or, The number of carton did he sale = $\frac{560}{28}$ = 20

Hence The total number of cartons did he sale is 20 . Answer

Yuki bought a pound of confetti for \$12$12. What is the price, in dollars, per ounce of confetti? There are 1616 ounces in 11 p

Ber [7]

Answer:

Price $0.75 per ounce of confetti

Step-by-step explanation:

Given the statement: Yuki bought a pound of confetti for $12.

⇒ $1 pound = \$ 12$ ......[1]

Also, it is given that there are 16 ounces in 1 pound.

⇒ 16 ounces = 1 pound .....[2]

To calculate the price, in dollars per ounce of confetti.

From [1] and [2] we have;

$16 ounces = \$12$

then;

1 ounces = $\frac{12}{16} = \frac{3}{4} = \$0.75$

Therefore, the price, in dollars per ounce of confetti is, $0.75 per ounce.
