Bred has to paint a wall with 8 horizontal stripes. He has enough paint only for 5 blue, 5 red and 5 white stripes. If he can us
Kay [80]

Answer:

336

Step-by-step explanation:

Required Formulas:-

1. Number of ways to select x things out of n things = ⁿCₓ

2. Number of ways to arrange n things when a things and b things are similar = n!/(a!*b!)

Since we have to choose 8 colors and we are having 3 different colors, it is only possible when we select 2 different colors (e.g. 5 red and 3 blue). To find all possible ways we will have to find all unique arrangements of selected color.

Using formula (1), number of ways to select 2 colors out of given 3 colors = ³C₂ = 3

Using formula (2), finding all unique arrangements when 5 stripes are of one color and 3 stripes are of second color = 8!/(3!*5!) = 56

Suppose, we can choose 5 stripes from red color and 3 stripes from blue color or 5 strips from blue color and 3 strips from red color. So there are 2 possibilities of arranging every 2 colors we choose .

∴ Answer=3*56*2 = 336

Part A: Solve −np − 70 &lt; 40 for n. Show your work. (4 points) Part B: Solve 4w − 7k = 28 for k. Show your work.
kondaur [170]
Hey!

For part A, let's write the problem,
-np-70\ \textless \ 40
Add 70 to both sides...
-np-70+70\ \textless \ 40+70
-np\ \textless \ 110
We are going to reverse the inequality, to do this we are going to multiply both sides by -1.
\left(-np\right)\left(-1\right)\ \textgreater \ 110\left(-1\right)
pn\ \textgreater \ -110
Divide both sides by p.
\frac{pn}{p}\ \textgreater \ \frac{-110}{p}
Our answer would be,
n\ \textgreater \ -\frac{110}{p}

Let's go with Part B. Let's write the problem,
4w-7k=28
Subtract 4w from both sides,
4w-7k-4w=28-4w
-7k=28-4w
Divide both sides by -7.
\frac{-7k}{-7}=\frac{28}{-7}-\frac{4w}{-7}
If we simplified it, we would be left with,
k=-\frac{28-4w}{7}

Thanks!
