Slope: 1/5 y-intercept: -7
Explanation: Slope is y=mx+b; where m is the slope and b is the y-intercept. Even though it’s positive b, it also can be negative (like -7)
Answer:
Step-by-step explanation:
We are given that
Angle of incidence,i=37.5 degree
We have to find the angle of refraction into the water made by ray wit the normal to the surface.
Refractive index of water,
By Snell's law
Again for glass water surface
Using Snell's law
Angle of incidence,i'=22.83 degree
Answer:
The angle is 35 degrees
Step-by-step explanation:
Since this is an isosceles triangle, we know that the two remaining angles must be the same. Set those angles equal to x. Now, we can solve for x by adding those two angles to the third angle and setting equal to 180.
x + x + 110 = 180
2x + 110 = 180
2x = 70
x = 35
Answer:
Number of roast beef sandwiches bought = 5
Step-by-step explanation:
Cost of a roast beef sandwich = $6.75
x = number of roast beef sandwiches bought
Amount Used for Payment = $50
Change Received = $16.25
Actual amount paid = Amount Used for Payment - Change Received
= $50 - $16.25
= $33.75
Actual amount paid = $33.75
Number of roast beef sandwiches bought = Actual amount paid / Cost of a roast beef sandwich
= $33.75 / $6.75
= 5 roast beef sandwiches
Number of roast beef sandwiches bought = 5
I'd think that the answer would be 0.15; are there any equations specified?
