Step-by-step explanation:

short hand radius = 4

distance travellled in 1 day revolution = 2πr= 2 x 22/7 x 4= 25.1cm (approx)

distance travellled in 2 day revolution= 25.1+ 25.1 = 50.2

long hand radius= 6

each hour 1 revolution by long hand so in 24 hr 24 revolutions and 48 he 48 revolution

distance travelled in 1 hr = 2πr= 2 x 22/7 x 6= 37.7

distance in 48hr = 37.7 x 48= 1809.6 (approx)

so sum of both= 1809.6 + 50.2 = 1859.8

Answer:

1910.12 cm

Step-by-step explanation:

2 days = 48 hrs = 2880 mins

One cycle of the short hand (4 cm) would be 12 hrs.

48/12 = 4 cycles

Circumference of a circle =  [tex]2\pi r[/tex]

r = 4 cm

2*pi*4 ≈ 25.13 cm (I only rounded to the hundredth, adjust as u need)

25.13 * 4 = 100.52 cm

One cycle of the long hand (6 cm) would be 60 mins (which is 1hr and two days would be 48hrs or 48 cycles. But let's keep this consistent).

2880/60 = 48 cycles

Circumference of a circle =  [tex]2\pi r[/tex]

r = 6 cm

2*pi*6 ≈ 37.70 cm (I only rounded to the hundredth, adjust as u need)

37.70 * 48 = 1809.6

100.52 + 1809.6 = 1910.12 cm

x = 5/2 or x = 1/3

C is the answer.

Answer:

x = 5/2 or x = 1/3

Step-by-step explanation:

Simplify  

( 2 x − 5 )( 3 x − 1 ) .

6 x 2 − 17 x + 5 = 0

Use the quadratic formula to find the solutions.

[tex]\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex] or [tex]\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex]

Substitute the values  a = 6 ,  b = − 17 , and  c = 5  into the quadratic formula and solve for  x .

17 ±sqrt(-17)^2-4*(6*5)

_________________

2*6

Simplify.

x = 17 ± 13 /12

The final answer is the combination of both solutions.

x = 5 /2 ,  1 /3

152 pencils remain after 14 days of school.

Step-by-step explanation:

Replace x in this formula with 14 (14 days):

f(14) = 250 - 7(14) = 250 - 98 = 152

-x+2y = 2

set 1st eq. equal  to 2nd equation since they both equal 2

x -2y = -x + 2y

Answer:

a(n) = 48*(1/4)^(n - 1)

Step-by-step explanation:

Here the first term, a(1), is 48 and the common ratio is r = 1/4.

Thus, the specific formula for the information given is

a(n) = 48*(1/4)^(n - 1)

9514 1404 393

Answer:

Step-by-step explanation:

Assuming your equation is ...

  v(t) = 20,000(0.88^t)

The value for t=0 is 20,000.

The value for t=11 is 20,000(0.88^11) ≈ 4,902.

The initial value is $20,000; the value after 11 years is $4,902.

Answer:

ITS A

i took the quiz :)

Step-by-step explanation:

The two true statements are:

The rule for Pattern B is "multiply by 2."

Each term in Pattern A is one-half the corresponding term in Pattern B.

Here we have two patterns:

First, let's analyze the patterns. For pattern A we can see that we just add 6 to each consecutive term, so this is an arithmetic sequence.

6 + 6 = 12

12 + 6 = 18

18 + 6 = 24

And so on.

For pattern B we multiply each term by 2 to get the next one, so this is a geometric sequence.

2*12 = 24

2*24 = 48

and so on.

Then we already can see that. "The rule for Pattern B is "multiply by 2." Is true

And:

The rule for Pattern A is "multiply by 2." is false.

Finally, let's compare the terms. The first term of B is 12, and the first ter of A is 6, so we can see that the first term of B is two times the first one of A. The second term of B is 24, while the second of A is 12, so again, we can see that the second term of B is two times the second of A.

So we can see a pattern, meaning that the statement: "Each term in Pattern A is one-half the corresponding term in Pattern B."

Answer:

68.3%

Step-by-step explanation:

Using the relation :

Zscore = (x - Mean) / standard deviation

For, x between 46 and 54

Zscore = ((54 - 50) / 4) - ((46 - 50) / 4)

P(Z < 4/4) - P(Z < -4/4)

P(Z < 1) - P(Z <-1)

0.84134 - 0.15866

= 0.68268

= 0.68268 * 100%
