HELPP! How many 3 digit numbers have a product of the digits that equals sixty?
gavmur [86]

Answer:

24

Step-by-step explanation:

Let's see the factor pairs of 60 first.

1,60

2,30

3,20

4,15

5,12

6,10

10,6

12,5

15,4

20,3

60,1

1,60 and 60,1 is not possible for xy1 and 1xy. It is because any one digit*one digit=not 60. The remaining pairs are...

2,30

3,20

4,15

5,12

6,10

10,6

12,5

15,4

20,3

30,2

Next, start with 2,30 and 30,2

The one digit factor pairs of 30 is 5 and 6.

So...

256 is possible

265 is possible

562 is possible

652 is possible

3,20

4,15

5,12

6,10

10,6

12,5

15,4

20,3

+4

Next, 3,20 and 20,3

20=4*5

453,543,345,354

4,15

5,12

6,10

10,6

12,5

15,4

+8

4,15 and 15,4

4 number that are possible(5*3=15)

5,12

6,10

10,6

12,5

+12

5,12 and 12,5

3,4 and 2,6

526,562,534,543,435,345,265,625

6,10

10,6

+20

10=5*2

+4

20+4=24

Cassidy has saved $8,000 this year in an account that earns 9% interest annually. Based on the rule of 72, it will take about ye
den301095 [7]

Answer:

The number of years in which saving gets double is 8 years .

Step-by-step explanation:

Given as :

The principal amount saved into the account = p = $8,000

The rate of interest applied = r = 9%

The Amount gets double in n years = $A  

Or, $A = 2 × p = $8,000 × 2 = $16,000

Let the number of years in which saving gets double = n years

Now,<u> From Compound Interest method</u>

Amount = Principal × (1+\dfrac{\textrm rate}{100})^{\textrm time}

Or, 2 × p = p × (1+\dfrac{\textrm r}{100})^{\textrm n}

Or, $16,000 = $8,000 × (1+\dfrac{\textrm 9}{100})^{\textrm n}

Or, \dfrac{16,000}{8,000} = (1.09)^{n}

Or, 2 = (1.09)^{n}

Now, Taking Log both side

Log_{10}2 = Log_{10} (1.09)^{n}

Or, 0.3010 = n × Log_{10}1.09

Or, 0.3010 = n × 0.0374

∴ n = \dfrac{0.3010}{0.0374}

I.e n = 8.04 ≈ 8

So, The number of years = n = 8

Hence, The number of years in which saving gets double is 8 years . Answer
