The length of a rectangle is 5ft longer than twice the width. if the perimeter is 70 ft. find the length and width of the rectan

vlada-n [284]

Let the width = x then we have that length = 2x + 5 and also that:
x + x + 2x + 5 + 2x + 5 = 70
6x + 10 = 70
6x = 60
x = 10

Therefore width = 10ft and length = 25ft

Each letter of the word "thunderstorm" has been written on a separate slip of paper and put into a box. Find the probability of

xxTIMURxx [149]

SOLUTION

From the question, we want to find the probability of selecting a slip of paper with the letter t on it, then selecting the letter r, with replacement.

This means the probability of selecting t and r.

That is

$P(t)\times P(r)$

There are 12 letters (total outcomes). And there are 2r and 2t.

So probability becomes

$\begin{gathered} \frac{possible\text{ outcome}}{\text{total outcome }} \\ P(t)=\frac{2}{12} \\ P(r)=\frac{2}{12} \\ P(t)\times P(r)=\frac{2}{12}\times\frac{2}{12} \\ =\frac{1}{6}\times\frac{1}{6} \\ =\frac{1}{36} \end{gathered}$

Hence the answer is

$\frac{1}{36}$

What’s the inverse equation?

algol [13]

Answer:

The inverse is ((5-x)/4) ^ 1/3

Step-by-step explanation:

y = 5-4x^3

Exchange x and y

x = 5-4y^3

Subtract 5 from each side

x-5 =5-5-4y^3

x-5 = -4y^3

Divide each side by -4

(x-5)/ -4 = y^3

Take the cube root

((x-5)/ -4) ^ 1/3 = y^ 3 ^1/3

((5-x)/4) ^ 1/3 = y

The inverse is ((5-x)/4) ^ 1/3
