find x. give your answer in the simplest form

Answers

Answer 1

Answer:

Step-by-step explanation:

sin = adjacent ÷ hypotenuse.

sin 45 = x ÷ 23

0.71 = x ÷ 23

0.71 × 23 = x

x = 16.26

~ 16.

Answer 2

Answer:

Step-by-step explanation:

using the Pythagorean theorem a² + b² = c²

in this triangle a = x and b = x so x² + x² = c² c is the hypotenuse

x² + x² = c²

2x² = c² since c = 23 solve for x

x² = c² / 2

x = ± √(c² / 2)

x = ± √(23² /2)

= ± √(529 /2)

= ± √(264.5)

= 16.26 x can't be negative

That is correct but it doesn't answer the question

x = ??? / √xx

sin 45 = √2 / 2 which equals x / 23

√2 / 2 = x / 23

x = 23 (√2 / 2)

= 23 (√2) / 2 divide the √2 numerator and demenator

= 23 (√2)/√2 / (2 / √2)

= 23 / (2 / √2)

Find the probability that a randomly selected points within a square falls in the blue shaded area (circle)

Answers

Answer:

78.8 %

Step-by-step explanation:

From the question,

Area of the square = L²

A = L²

Where L = Length of the square.

From the diagram,

L = 4 in

Therefore,

A = 4²

A = 16 in².

Also,

Area of the circle (A') = πr²

Where r = radius of the circle.

Given: r = 2 in

Therefore,

A' = 22/7(2²)

A = 12.6 in²

Hence,

The probability that a randomly selected points within a square falls in the blue shaded area (Pr) = A'/A

Pr = 12.6/16

Pr = 0.7875

Pr(%) = 78.75

Pr(%) = 78.8 %

p-5 = 19
answer step by step & explain

Answers

Answer:

Step-by-step explanation:

Very simple.

p - 5 = 19

So to take out the -5 on that side, you must also do the same thing to the other side. So adding 5 in one side of the equal sign would mean you have to do the same thing on the other side of the equal sign.

SO:

p-5 +5 = 19+5

p = 24

P=26

26-5=19

(19+5 is also 26 so you can check your work that way)
