Responder:
Número total de bolas = 245/23
Explicación paso a paso:
Dado que:
Bolas blancas = 1/5
Bolas negras = 1/7
Bolas rojas = 7
Sea el número total de bolas = x
Bolas blancas = 1 / 5x
Bolas negras = 1 / 7x
Por tanto, total;
(x / 5 + x / 7 + 7) = x
((7x + 5x) / 35) +7 = x
(12x / 35) + 7 = x
7 = x - 12x / 35
7 = (35x - 12x) / 35
7 = 23 veces / 35
245 = 23x
x = 245/23
find total area by multiplying 350' x 200' = 70,00 sq ft
area of one block, multiply 25' x 25' = 625 sq ft = area for one Security guard
divide area for one security guard into total area of facility 70,000 / 625 =
112 security guards
find how many people for each block = 70,000 / 625 = 112 blocks
12,000 people divided by 112 blocks = 12,000 / 112 = 107.14 rounded to nearest 10 = 110 people per block
Your answer will be X = 11 over 2, if that's a 2 over 5 in the beginning of the problem
Answer:
D:95 mm Hg
Step-by-step explanation:
Using the linear model, y=x+95, x represents the age and y represents the blood pressure.
For a newborn, x=0 this gives us
>
y=0+95 = 95<
