Answer:

48

Step-by-step explanation:

MPQ + QPN = MPN

9x-6 + 5x+7 = 85

Combine like terms

14x+1 = 85

Subtract 1 from each side

14x+1-1 = 85-1

14x = 84

Divide by 14

14x/14 = 84/4

x=6

We want MPQ

MPW = 9x-6 = 9*6 -6 = 54-6 =48

An object is thrown upward from the top of 96​-foot building with an initial velocity of 80 feet per second. The height h of the
stiks02 [169]

The function of the object height is an illustration of a projectile motion

The object will never hit the ground

<h3>How to determine when the object hits the ground?</h3>

The function is given as:

h=16t^2+80t+96.

When the object hits the ground, h = 0

So, we have:

16t^2+80t+96 = 0

Divide through by 16

t^2+5t+6 = 0

Expand

t^2 + 3t + 2t + 6 = 0

Factorize

t(t + 3) + 2(t + 3) = 0

Factor out t + 3

(t + 2)(t + 3) = 0

Solve for t

t = -2 or t = -3

The time (t) cannot be negative.

Hence, the object will never hit the ground

En una oficina hay 96 computadores en total. La razón entre los computadores que deben ser reparados y aquellos que se encuentra
Alik [6]

Answer:

36 computadores deben ser reparados.

Step-by-step explanation:

Dado que en una oficina hay 96 computadores en total, y la razón entre los computadores que deben ser reparados y aquellos que se encuentran operativos es 3:5, para determinar cuántos computadores de la oficina deben ser reparados en total se debe realizar el siguiente cálculo:

(96 / (3+5)) x 3 = computadores que deben ser reparados

(96 / 8) x 3 = computadores que deben ser reparados

12 x 3 = computadores que deben ser reparados

36 = X

Por lo tanto, 36 computadores deben ser reparados.
