Step-by-step explanation:

because it is 24 radius

Answer:

135°

Step-by-step explanation:

To convert Radians to Degrees, you multiply the Radians amount by [tex]\frac{180}{\pi}[/tex].

Thus, we get [tex]\frac{3\pi }{4}[/tex] * [tex]\frac{180}{\pi}[/tex]

We then get [tex]\frac{540\pi }{4\pi }[/tex], which simplifies into 135 degrees.

Answer: a = 0.91421

Step-by-step explanation:

Hi! I'm assuming this question is using degrees for sin and not radians, let me know if that's right!

The equation seems a bit weird, but

a is approximately 0.91421

if you go to wolframalpha site, you can plug in this equation to the website and receive an answer !

Answer:

3/128

Step-by-step explanation:

first term: 3/1

second term: 3/1*1/2 = 3/2

third term: 3/2*1/2 = 3/4

fourth term: 3/4*1/2 = 3/8

fifth term: 3/8 * 1/2= 3/16

sixth term: 3/16 * 1/2 = 3/32

seventh term: 3/32 * 1/2 = 3/64

eighth term: 3/64 * 1/2= 3/128

Only 1, 54.

There are obviously no such 1-digit numbers (1 - 9).

Let n = ab be a 2-digit number whose value is 6 times its digit sum, meaning

n = 10a + b = 6 (a + b)

Then

10a + b = 6a + 6b

4a = 5b

Now, 4 and 5 are coprime, so for equality to hold, a must be a multiple of 5 and b must be a multiple of 4.

The only valid multiple of 5 is 5 itself:

• a = 5   ⇒   5b = 20   ⇒   b = 4

There are 2 multiples of 4 to check. The first one gives the same result as a = 5.

• b = 8   ⇒   4a = 40   ⇒   a = 10

but a must be 1-digit.

So among the 2-digit numbers, only 1 such number exists, n = 54.

Let n = abc be a 3-digit number satisfying the criterion. Then

n = 100a + 10b + c = 6(a + b + c)

100a + 10b + c = 6a + 6b + 6c

94a + 4b = 5c

c must be a number from 1-9, which means at most 5c = 5•9 = 45.

If we take the smallest possible values of a and b, we have

94•1 + 4•0 = 94

but the smallest value of 94a + 4b is larger than the largest value of 5c.

So there are no such 3-digit numbers.

Answer:

[tex]\frac{1}{45}[/tex] chance to grab both $20 bills

Step-by-step explanation:

There are ten bills in total.

The probability that the first dollar she picks is a twenty-dollar bill is 2/10 because she can pick either of the two twenty-dollar bills out of the ten in her wallet. Next, we need to pick the second bill. There are nine bills left, and only one is a twenty-dollar bill. The probability of choosing a second dollar bill is 1/9.

(2/10)*(1/9)=2/90=1/45

Answer:

√408

Step-by-step explanation:

First of all, let's name the top triangle n and the bottom one m, you can name them as you'd like.

okay, so, based on the Pythagorean theorem, a^2 + b^2 = c^2

now, we know that the area that is 12 units long, is equivalent to the hypotenuse of m, (it's very important that the bottom right angle is 90 degrees) and therefore, (5^2 = 25)    5^2 + ___ = 12^2  now let's solve that:

25 + _____ = 144 now just fill in the blank. With a simple subtraction, we get 119 (144 - 25 = 119), now remember, this is c^2 of m

and, 12+5=17 so, a of the n triangle is 17.

so let's put everything together: 17^2 + 119 = x^2

now, we're gonna calculate it: 17^2 = 289 and we're gonna add that to 119, so we get 408: 289 + 119 = x^2

But, this is x^2, and we want to find the value of x, so we have to find the square root of 408. Since we get a number with a lot of decimals in front of it, we're just gonna leave it as is, therefore the answer is √408

Hope it helped!

Answer:

The initial value of all linear functions that show a proportional relationship is 0. If it is a proportional linear relationship the origin of the function is at (0,0).

Answer:

B) 3.14(144)

D) 2(3.14)(12)

E) 3.14(24)

Step-by-step explanation:

The formula to find the area of a circle is [tex]\pi r^2[/tex], where r = radius, while the formula to find the circumference of a circle is [tex]2\pi r[/tex] or [tex]\pi d[/tex], where r = radius and d = diameter.

Given the information above, option B) is a correct statement because 12^2 equals 144, and once you're done solving the square, you multiply it by 3.14. Next, option D) and E) are correct, too, because they exactly follow [tex]2\pi r[/tex] and [tex]\pi d[/tex]. Furthermore, for E), diameter = twice the radius, so it makes sense to multiply 3.14 by 24.

The value of x is 7 in both similar triangles.

Given that the two triangles are similar. The attachment shows the triangles.

[tex]\Delta MNP[/tex] is equivalent to [tex]\Delta OPR[/tex]. Also, [tex]\angle MPN[/tex] is equal to [tex]\angle OPR[/tex] and both are right angles. Also given that,

NO = 6, NP = 8, MP = 2x-2, PR = 3x

Thus, OP = NO + NP

OP = 6+8= 14

As per the AA postulate of similarity theorem of triangles, the corresponding sides will be equal.

[tex]\dfrac {OP}{NP} = \dfrac {PR}{MP} =\dfrac {OR}{MN}[/tex]

We take the two sides,

[tex]\dfrac {OP}{NP} = \dfrac {PR}{MP}[/tex]

[tex]\dfrac {14}{8} = \dfrac {3x}{2x-2}[/tex]

[tex]28x-28 = 24x[/tex]

[tex]4x = 28[/tex]

[tex]x = 7[/tex]

Hence we can conclude that the value of x is 7.
