J + p + m = 39
m = 4p ....m = 4(j - 3)....m = 4j - 12
p = j - 3

j + j - 3 + 4j - 12 = 39
6j - 15 = 39
6j = 39 + 15
6j = 54
j = 54/6
j = 9 <== justin

m = 4j - 12
m = 4(9) - 12
m = 36 - 12
m = 24 <=== matt

p = j - 3
p = 9 - 3
p = 6 <===peyton

Una fabrica produce 132 litros de yogurt diarios .Con 49 litros se llenan botellas de 0,25litros xada una y con el resto que que
nordsb [41]

Answer:

z = 362\,botellas

Step-by-step explanation:

(This exercise has been presented in Spanish and for that reason explanation will be held in Spanish)

La cantidad de botellas de 0,25 litros que se llenan con 49 litros de yogurt es:

x = \frac{49\,L}{0.25\,\frac{L}{botella} }

x = 196\,botellas

La cantidad remanente de yogurt es:

V_{r} = 132\,litros - 49\,litros

V_{r} = 83\,litros

Ahora, la cantidad de botellas de 0,5 litros que se llenan con el volumen remanente es:

y = \frac{83\,litros}{0.5\,\frac{litros}{botella} }

y = 166\,botellas

Finalmente, el total de botellas a llenar es:

z = 196\,botellas + 166\,botellas

z = 362\,botellas

A teacher promised a movie day to the class that did better, on average, on their test. The box plot shows the results of the te
masha68 [24]
I say it is C. Basically I just eliminate the potential answered down. A could not be the one since not all student in 2nd period got 100% and average students got below 95%. B cannot be it since both box plot have the same median. I do not think D is it because of how the answer is told. "The 4th period class should get the reward. Their lowest score is an outlier, and should be thrown out," it sound childish and makeing a joke to put "and should be thrown out." I may be wrong but that is my opinion. The relatively the best and reasonable answer is C.

the diameter of a football is five times the diameter of a cricket ball ratio of surface area of football and cricket ball is​
LenKa [72]

Answer:

25 : 1

Step-by-step explanation:

The diameter of the football is 5 times the diameter of the cricket ball. This means that the radius of the football is also 5 times the radius of the cricket ball.

Let the radius of the football be R.

Let the radius of the cricket ball be r.

This implies that:

R = 5r

Both balls are spherical.

The surface area of the cricket ball is given as:

a = 4\pi r^2

The surface area of the football is given as:

A = 4\pi R^2

=>A = 4\pi (5r)^2\\\\A = 100\pi r^2

Therefore, the ratio of their surface areas is:

A : a

100\pi r^2 : 4\pi r^2

= 100 : 4

25 : 1
