Answer:

x=-11

Step-by-step explanation:

12-4(x+2)=48

Subtract 12 from each side

12-12-4(x+2)=48-12

-4(x+2)=36

Divide by -4

-4(x+2)/-4=36/-4

x+2 = -9

Subtract 2

x+2-2 = -9-2

x=-11

Answer:

x = -11

12 - 4x - 8 = 48

4 - 4x = 48

-4x = 44

x = -11

At a distance of 10 cm from a presumably isotropic, radioactive source, a pair of students measure 55 cps (cps = counts per seco

professor190 [17]

With an isotropic source, you can think on the radiation like a expanding sphere, where you will measure the same cps in any point while you keep the same distance to the source, ence the radius of the sphere remains constant. So, you know that the relation depends on the radius, also, when the sphere grows, the radiation in it expands in more surface, ence the density of particles will decrease, particularly, like $\frac{1}{r^{2} }$

then, in 15cm you will have 55cps = A/(10*10) where A is the "intensity of the source" whit this you can know the value of A = 55cps*100 $cm^{2}$ .

then, for 22cm, Y = 55cps*100/(22*22) = 20.66 cps.

The math club is fast becoming one of the most popular clubs on campus because of the fabulous activities it sponsors annually f

Answer:

The many members should the club expect to have 5 years from now is 167.

Step-by-step explanation:

The number of members in the club at present is, 45.

It is provided that each year the club's enrollment increases by 30%.

Compute the increasing rate as follows:

$Rate=1+0.3=1.3$

Then the number of members in the club after n years is given by the equation:

$Number\ of\ members\ after\ n\ years=45\times (1.3)^{n}$

Compute the number of members in the club after 5 years as follows: $Number\ of\ members\ after\ 5\ years=45\times (1.3)^{5}\\=45\times (1.3)^{5}\\=45\times 3.71293\\=167.08185\\\approx167$
