Answer:

x=28

Step-by-step explanation:

From the diagram we know that the angle m<3 = m<4 and the angle m<1 = m<2. Also we know that the sum of the four angles must be equal to 360.

Summarizing:

1. m<3 = m<4

2. m<1 = m<2

3. m<1 + m<2 + m<3 + m<4 = 360

Substituting 1 and 2 in equation three we have:

4. 2m<2 + 2m<3 = 360.

Now, we know that m<3 = 3x + 16 and m<2 = x + 84. Substituting in equation 4:

2 ( x + 84) + 2 ( 3x + 16) = 360

Solving for x:

2x + 168 + 6x + 32 = 360

8x = 224

x=28

At what angle does a diffraction grating produce a second-order maximum for light having a first-order maximum at 20.0 degrees?

hichkok12 [17]

Answer:

At 43.2°.

Step-by-step explanation:

To find the angle we need to use the following equation:

$d*sin(\theta) = m\lambda$

Where:

d: is the separation of the grating

m: is the order of the maximum

λ: is the wavelength

θ: is the angle

At the first-order maximum (m=1) at 20.0 degrees we have:

$\frac{\lambda}{d} = \frac{sin(\theta)}{m} = \frac{sin(20.0)}{1} = 0.342$

Now, to produce a second-order maximum (m=2) the angle must be:

$sin(\theta) = \frac{\lambda}{d}*m$

$\theta = arcsin(\frac{\lambda}{d}*m) = arcsin(0.342*2) = 43.2 ^{\circ}$

Therefore, the diffraction grating will produce a second-order maximum for the light at 43.2°.

I hope it helps you!

a chef uses 5 2/5 pounds of ground beef to make a hamburger and 2 1/4 pounds of ground beef to make meatloaf. the ground beef co

Lisa [10]

Answer:

16 packages

Step-by-step explanation:

5 2/5 + 2 1/4 Use the common denominator of 20

5 8/20 + 2 5/20

7 13/20

I know that I will need 14 packages for the 7 pounds. For the fraction part, 10/20 would be half, so I would need to buy a half pound for that, but I need 13/20 which would be more than a half pound, so I will need to buy 2 more pounds for the fraction part.

14 + 2 = 16

The point-slope form of the equation of the line that passes through (–4, –3) and (12, 1) is y – 1 = (x – 12). What is the stand

yanalaym [24]

y-y1 = m (x-x1) y+3 = (1/4)(x+4) [using point (x1,y1)] or y–1 = (1/4)(x–12) [using point (x2,y2] [let's use this one since you did] To put this into Standard Form (Ax+By=C), y–1 = (1/4)(x–12) 4y - 4 = x - 12 -x + 4y - 4 = -12 [subtract x from both sides] -x + 4y = -8 [add 4 to both sides] x - 4y = 8 [multiply by (-1) to have x-coefficient positive

Kyle has three short straws, four medium straws, and six long straws. If he randomly draws two straws, one at a time without rep

ipn [44]

Before the first straw is drawn, there are three short straws and $3+4+6=13$ straws in all. Thus, the probability of drawing a short straw first is $\frac{3}{13}$ .

After a short straw is drawn, there are two short straws and twelve total straws, a probability of $\frac{2}{12} = \frac{1}{6}$ .

Thus, the probability of both of these events occurring is $\frac{3}{13} \cdot \frac{1}{6} = \boxed{\frac{1}{26}}$ .
