A. Karel should charge less than $2 if she wants to be the cheapest (x<$2). x would represent what she charges.
B. She should charge $2.75 if she wants to charge what most other sitters are charged because this amount occurs more than any other(the mode).
C. She should also charge $2.75 if she wants to be in the middle (median).
D. When deciding on a rate, Karel should also consider if there are any rates that are a lot lower or a lot higher because there might be a reason (more kids, unusual hours, relatives, etc...).
A) To find the surface area of a cube, you have to use the formula 6•a^2
meaning you just have to calculate one side and multiply it by six.
541.5 is the surface area of the cube.
B) To find the surface area for just five sides, you'll be doing the same, except instead of 6 it'll be five.
so multiply 9.5 by itself
you get 90.25
Then you multiply 90.5 by 5
You get 451.25
Unfortunately I'm not sure how to do C. good luck
If <em>y</em> = <em>A</em> sin(<em>x</em>) + <em>B</em> cos(<em>x</em>), then
<em>y'</em> = <em>A</em> cos(<em>x</em>) - <em>B</em> sin(<em>x</em>)
<em>y''</em> = -<em>A</em> sin(<em>x</em>) - <em>B</em> cos(<em>x</em>)
Substitute these into the ODE:
4<em>y''</em> + <em>y'</em> + 5<em>y</em> = 2 cos(<em>x</em>)
4 (-<em>A</em> sin(<em>x</em>) - <em>B</em> cos(<em>x</em>)) + (<em>A</em> cos(<em>x</em>) - <em>B</em> sin(<em>x</em>)) + 5(<em>A</em> sin(<em>x</em>) + <em>B</em> cos(<em>x</em>)) = 2 cos(<em>x</em>)
(-4<em>A</em> - <em>B</em> + 5<em>A</em>) sin(<em>x</em>) + (-4<em>B</em> + <em>A</em> + 5<em>B</em>) cos(<em>x</em>) = 2 cos(<em>x</em>)
(<em>A</em> - <em>B</em>) sin(<em>x</em>) + (<em>A</em> + <em>B</em>) cos(<em>x</em>) = 2 cos(<em>x</em>)
Then
<em>A</em> - <em>B</em> = 0
<em>A</em> + <em>B</em> = 2
Adding these equation gives
(<em>A</em> - <em>B</em>) + (<em>A</em> + <em>B</em>) = 0 + 2
2<em>A</em> = 2
<em>A</em> = 1 → <em>B</em> = 1
The answer is 20.
Solution for 5 is what percent of 25:
5: 25*100 =
(5*100): 25 =
500: 25 = 20
Now we have: 5 is what percent of 25 = 20
Question: 5 is what percent of 25?
Percentage solution with steps:
Step 1: We make the assumption that 25 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=25$100%=25.
Step 4: In the same vein, $x\%=5$x%=5.
Step 5: This gives us a pair of simple equations:
$100\%=25(1)$100%=25(1).
$x\%=5(2)$x%=5(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{25}{5}$
100%
x%=
25
5
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{5}{25}$
x%
100%=
5
25
$\Rightarrow x=20\%$⇒x=20%
Therefore, $5$5 is $20\%$20% of $25
