Answer 1

Answer: (55,9) Explanation is below.

Step-by-step explanation:

What you want to do is try to mutliply one of your equations so that either y or x will be canceled out.

Here is the example:

Say you want to get rid of x, you can multiply the first equation: x-5y=10 by -2 to match the second equation: -2x+6y=-16.

Therefore, the first equation would become -2(x-5y=10)=> -2x+10y=-20

Then subtract the first equation from the second:

 (-2x+6y= -16)

- (-2x+10y = -20)

-------------------------

=> 0x-4y= -36

Simplify and then you get y=9.

To find x, plug in y into one of the equations: x-5(9)=10 => x-45=10 => x=55

Sorry if I didn't explain it correctly.

A bag contains 2 black balls, 4 yellow balls and 4 white balls. Event A is defined as drawing a white ball on the first draw and event B is defined as drawing a black ball on the second draw. If two balls are drawn from the bag, one after the other and not replaced, what is P(B|A) expressed in simplest form? A. B. C. D.

Answers

Answer: [tex]P(B|A)=\dfrac{4}{9}[/tex]

Step-by-step explanation:

Given: A bag contains 2 black balls, 4 yellow balls and 4 white balls.

Event A is defined as drawing a white ball on the first draw.

Event B is defined as drawing a black ball on the second draw.

P(B|A) is expressed as the conditional probability of occurring B given that A.

i.e. it is the probability of happening B where A is already happended.

If a white ball is drawn at first, then the number of black ball(4) remains unchanged but the total number of balls (10) will become 9.

[tex]Probability=\dfrac{Number\ of \ favorable \ outcomes}{Total\ outcomes}[/tex]

Then, [tex]P(B|A)=\dfrac{4}{9}[/tex]

a 38-ft ladder is leaning against a building the bottom of the ladder is 7 ft from the base of the building to the nearest foot how high it does the ladder reach the building?​

Answers

Answer:

37 ft.

Step-by-step explanation:

Use the Pythagorean theorem to solve.  

The hypotenuse = 38 and a leg is 7.  

Let d = distance from ground to top of the ladder

[tex]38^{2} = x^{2} + 7^{2}[/tex]

1444 = [tex]x^{2} + 49[/tex]

[tex]x^{2} = 1395\\x = \sqrt{1395} = 37.3496...\\37 ft.[/tex]
