Answer:

[tex]x = 25.9[/tex]

Step-by-step explanation:

Apply law of sines.

[tex] \frac{23}{ \sin(22) } = \frac{x}{ \sin(25) } [/tex]

[tex] \frac{23}{ \sin(22) } \times \sin(25) = x[/tex]

[tex]x = 25.9[/tex]

Answer:

25.9

Step-by-step explanation:

By sine rule:

[tex] \frac{BC}{ \sin 25 \degree} = \frac{23}{ \sin 22 \degree} \\ \\ BC = \frac{23 \sin 25 \degree}{ \sin 22 \degree} \\ \\ BC = \frac{9.72022002}{ \sin 22 \degree} \\ \\BC = 25.947808156 \\ \\ BC \approx \: 25.9[/tex]

Step-by-step explanation:

Answer:

With replacement

[tex]probability \ of \ spade = \frac{13}{52} = \frac{1}{4} \\\\ probability \ of red\ card = \frac{26}{52} =\frac{1}{2}[/tex]

[tex]probability \ of \ spade \ then \ red\ card\ without\ replacement =[/tex][tex]\frac{1}{4} \times \frac{1}{2} = \frac{1}{8}[/tex]

Without replacement

[tex]probability \ of\ spade = \frac{13}{52} = \frac{1}{4} \\\\probability \ of \ spade\ again =\frac{12}{51} = \frac{4}{17}[/tex]

[tex]probability \ of \ spade \ then \ red\ card\ without\ replacement = \frac{1}{4} \times\frac{4}{17} =\frac{1}{17}[/tex]

Answer:

46 degrees

Step-by-step explanation:

You should know that measures QRS, which form a horizontal line, measures up to 180 degrees. (Just like a right angle adds to 90 degrees). So, TRS is 42 degrees and URT is 92 degrees, that would make QRU measure 46 degrees because 180 - 92 - 42 = 46 degrees.

Hope that helps you!! Please give me brainliest!! ;)

Answer:

42°

Step-by-step explanation:

A horizontal, or flat line is 180°. This means the total measures of ∠TRS, ∠URT, and ∠QRU, are 180°. We can subtract the given measures from 180 to find the measure of ∠QRU.

∠TRS = 42°

∠URT = 92°

Subtract 42 and 92 from 180.

180 - 42 - 92 = 46

∠QRU = 42°

m∠QRU in circle R is 42°.

Good luck ^^

Answer:

[tex] x = \dfrac{1}{5} \pm \dfrac{\sqrt{46}}{5} [/tex]

Step-by-step explanation:

5x^2 - 2x - 9 = 0

a = 5; b = -2; c = -9

[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]

[tex] x = \dfrac{-(-2) \pm \sqrt{(-2)^2 - 4(5)(-9)}}{2(5)} [/tex]

[tex] x = \dfrac{2 \pm \sqrt{4 + 180}}{10} [/tex]

[tex] x = \dfrac{2 \pm \sqrt{184}}{10} [/tex]

[tex] x = \dfrac{2 \pm \sqrt{4 \times 46}}{10} [/tex]

[tex] x = \dfrac{2 \pm 2\sqrt{46}}{10} [/tex]

[tex] x = \dfrac{1 \pm \sqrt{46}}{5} [/tex]

[tex] x = \dfrac{1}{5} \pm \dfrac{\sqrt{46}}{5} [/tex]

Answer:

15

Step-by-step explanation:

hypotenuse (h) = 25

perpendicular (p) = 20

base (b) = ?

we know by using Pythagoras theorem we get

b = √h² - p²

  = √25² - 20²

  = √225

  = 15

Answer:

Probability = 37.5%

Step-by-step explanation:

Prob (Race fast) = 10%, Prob (Slight Fast) = 40%, Prob (Normal Car) = 50%

Prob (Red Car) = 70% of race fast cars, & 45% of slight fast cars, & 30% of Normal cars, & = (70% x 10%) + (45% x 40%) + (30% x 50%) = 7% + 18% + 15% = 40%

Prob (Normal & Red Car) = 30% of 50%  = 15%

Prob (Red car I Normal car) = Prob (Red & Normal Car I Normal Car) =  15% / 40% = 37.5%

triangles add up to 180

180-43-90=47

Answer:

48in^2 or just 48 dont forget to include the inches and squared

Step-by-step explanation:

Answer:

Using their equation and the fact that the ball will fall 3 ft before reaching the ground:

3 = 16 t^2 + 50 t + 3  represents the given situation

16 t^2 + 50 t = t (16 t + 50) = 0

16 t + 50 = 0

t = 50 / 16 = 3.12 sec

Answer:

A

Step-by-step explanation:

short cut, it has 5 dashes/ point markings

Answer: (a)

Step-by-step explanation:

Given

The diameter of the inner circle is [tex]d=14\ m[/tex]

thickness of the strip is [tex]t=2\ m[/tex]

So, the radius of inner circle is [tex]r=7\ m[/tex]

Radius of the outer circle [tex]R=7+2=9\ m[/tex]

Area of the shaded region is the difference of the area of outer circle and inner circle.

[tex]\Rightarrow \pi R^2-\pi r^2\\\Rightarrow \pi (9^2-7^2)\\\Rightarrow 3.142\times 32\\\Rightarrow 100.5\ m^2[/tex]

hence, option (a) is correct.

Answer:

Now let n=i, and write, ui=7i-4. Hence, 3+10+17+24+31+38=∑6i=1 (7i-4).

Answer:

Now let n-i, and write, ui-7i-4. Hence, 3+10+17+24+31+38=26i-1 (7i-4).

Answer:

7 times (*) 8

Step-by-step explanation:

Product in this case means multiplication

Answer:

a)  median = 1,148 minutes

b)  IQR = 549.5

Step-by-step explanation:

Q1 = (952 + 866) / 2 = 909

Q3 = (1431 + 1486) / 2 = 1458.5

IQR = 1458.5 - 909.0 = 549.5
