Answer:

$5.1$ × $10^{-4}$

$6.3$ × $10^{-3}$

Step-by-step explanation:

If you move the decimal 4 times to the right, since it's a negative, you'll get the number 0.00051.

If you move the decimal 3 times to the right, since it's also a negative, you'll get the number of 0.0063.

Hope this helps!

Melanie bought 3 adult tickets and 1 children ticket for $38. John bought 3 adult tickets and 2 children tickets for $52. What i

Vlad [161]

If the cost of adult ticket is x and that of children ticket is y
Then 3x +y = $38
3x+2y =$52, solving simultaneously
we subtract the two equation,
-y = -14
thus; y =14
to get x we substitute y with 14
3x = 38-14
3x =24
x =8
Therefore, the cost of 1 adult ticket is $8 while the cost of children ticket is $14

For a circle of radius 9 feet, find the arc length s cut off by a central angle of 6°

ICE Princess25 [194]

$\bf \textit{arc's length}\\\\ s=\cfrac{\pi \theta r}{180}~~ \begin{cases} r=radius\\ \theta =angle~in\\ \qquad degrees\\ \cline{1-1} r=9\\ \theta =6 \end{cases}\implies s=\cfrac{\pi (6)(9)}{180}\implies s=\cfrac{3\pi }{10}\implies s\approx 0.94$

Answer:

The answer is 20

Step-by-step explanation:

Given that f(2)=1/5

And f(n+1)=f(n)*10

Let's start from n=2

f(2+1)=f(2)*10

f(3)=(1/5)*10

f(3)=2

Now let's take n=3

f(3+1)=f(3)*10

f(4)=2*10

f(4)=20
