Starting with 54 and 36, replace the 54 with the greatest common divisor of 54 and 36, obtaining a1, and then replace 36 with th

nalin [4]

Answer:

1 time

Step-by-step explanation:

Given numbers are 54 and 36.

The greatest common divisor of 54 and 36 = 18

So, $a_1 = 18$ .

The least common multiple of 54 and 36 = 108

So, $b_1 = 108$ .

As 54 is replaced by $a_1$ and 36 is replaced by $b_1$ , so after applying the given procedure, the new number is

$(a_1, b_1)=(18, 108)\cdots(i)$

Now, apply the same procedure, to get $a_2$ and $b_2$ .

The greatest common divisor of 18 and 108 = 18

So, $a_2 = 18$ .

The least common multiple of 18 and 108 = 108

So, $b_2 = 108$ .

As $a_1$ is replaced by $a_2$ and $b_1$ is replaced by $b_2$ , so after applying the given procedure, the new number is

$(a_2, b_2)=(18, 108)$ which is the same as in equation (i)

Hence, after applying the procedure 1 time after $(a_1, b_1)$ , the obtained number $(a_2, b_2)$ is the same as $(a_1,b_1)$ .

Calculate the total cost of an item bought at a negotiated price of $15,640 and a $2,500 trade-in-allowance. The sales tax is 7.

Fofino [41]

Hey! :)

The total cost of the item is the second choice which is $14,372.08. I arrived to the answer by simply:
1) multiplying the sales tax to the negotiated price (15640*.072 = 1126.08)
2) adding the sales tax to the negotiated price and the registration as well (15640+1126.08+106= 16872.08)
3) subtracting the trade in allowance from the computed value (16872.08 - 2500 = 14372.08)
Hope this helps! :)

Volume of a sphere r=5

Reptile [31]

V = 4/3 (3.14) (5) to the third power 3
(5)3rd = 125
4/3 x (3.14 x 125)
3.14 x 125 = 392.5
4/3 x 392.5 = 1570 / 3
Volume = 523.33
