In rectangle PQRS, PR = 18x – 28 and QS = x + 380. Find the value of x and the length of each diagonal.

Flauer [41]

Diagonals of a rectangle are congruent.

18x - 28 = x + 380

Solving for x, I get 17.

So, x = 17.

PR = 18x - 28

PR = 18(17) - 28

PR = 278

QS = x + 380

QS = 17 + 380

QS = 397

Rearrange x = 7y - 5 to make y the subject.

nalin [4]

By rearranging x = 7y - 5 to make y the subject, we get

x + 5 = 7y ( By transposition method )

or, $\huge \purple {\tt {\frac{x + 5}{7} = y}}$

<h2>Answer:</h2>

$\huge \pink {\tt {y = \frac{x + 5}{7}}}$

In the Minnesota Northstar Cash Drawing, you pick five different numbers between 1 and 35. What is the probability of picking th

maw [93]

Answer:

$\frac{1}{324632}$ probability of picking the winning combination

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Since the order is not important, the combinations formula is used to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Desired outcomes:

The correct five numbers from a set of 5. So

$D = C_{5,5} = \frac{5!}{5!0!} = 1$

Total outcomes:

Five numbers from a set of 35. So

$T = C_{35,5} = \frac{35!}{5!30!} = 324632$

Probability:

$p = \frac{D}{T} = \frac{1}{324632}$

$\frac{1}{324632}$ probability of picking the winning combination
