Eight students got a B on the final test. If the ratio of the number of studenst who got an A to the number of student who got a B is y : X, how many students got an A? What if x is 2 and y is 3?

1) x = 2 and y = 3: 12 students got an A.

2) x = 4 and y = 3 6 students got an A. (from the comments)

Step-by-step explanation:

Hopefully I read this right, but the ratio you're trying to find is A : B = y : x

1) Plug in x = 2 and y = 3 to get 3 : 2. Because we know 8 students got a B we're going to multiply by 4 on each side to get 12 : 8 (12 A students and 8 B students).

2) You asked this in the comments so I answered it as well. Do the same thing as 1):

Plug in x = 4 and y = 3 to get 3 : 4.

We know there's 8 B students so multiply by 2 to get 6 : 9. 6 A students and 9 B students.

x=2 and y=3 12 students got an A.

x=4 and y=3 6 students got an A.

hope this helps sry its really late and sry if its wrong i tried :|

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
