Answer:

(a) and (b) are true

Step-by-step explanation:

a) is true.

b) is true. Replacing x with 8 in the equation y=1/4x-5 results in 2-5, or -3.

c) is false. See (a), above.

d) is false. Replacing x in the equation by 12 results in y = (1/4)(12) - 5, or -2.

Answer:

$V_f=450ml/hr$

Step-by-step explanation:

From the question we are told that:

Mass $m=15kg$

Amount of NaCl IV $n=0.9\%$

Rate $R=30ml/kg/hr$

Generally the equation for fluid rate be for your IV pump is mathematically given by

$V_f=mR$

Since

Rate is

30ml/kg/hr at 1kg patient Weight

Therefore

$V_f=15*30$

$V_f=450ml/hr$

Answer:

Análisis del problema

Nos dan como datos el tiempo que se tarda cada uno en pintar la habitación:

Gerardo: 3 horas

Ángel: 6 horas

La velocidad de trabajo podemos definirla como dada por la cantidad de habitaciones que pueden pintar sobre el tiempo: H/t

Gerardo: 1 hab /3h

Ángel: 1 hab / 6h

Sumamos ambas velocidades de trabajo:

Por lo tanto entre los dos pintarían una habitación en dos horas.

Answer:

Height of Tower = 41.8901 ft

Base to Ground Wire = 94.0905 ft

Step-by-step explanation:

So you want to find the opposing side of the angle, as well as the distance from the base to where the wire is attached to the ground. You would need to use CAH to find the ground, and SOH to find the height. To find the height or opposite, take the Sine of 24°, 0.4067, and times it by your hypoteneuse 103 to get an exact height of 41.8901 ft. Next, use the Cosine of 24°, 0.9135, and times that by your hypoteneuse 103 to get 94.0905 ft.

Here are the equations:

sin(24)= $\frac{h}{103}$
