Need help ASAP:)))))))))))))<br>Pls show ur work!<br>1.2x + 7 - 5x <br><br>2.2c - 3 = 2(6 - c) + 7c
USPshnik [31]

Answer:

c = -75/14 OR c = -5.357143

Step-by-step explanation:

Simplify both equations:

1.2x + 7 - 5x =

-3.8x + 7

2.2c - 3 = 2(6 - c) + 7c =

c = −5.357143

OR

c = -75/14

The question wasn't quite clear, if this wasn't correct, please elaborate on what needed to be solved, and I'll fix my answer.

Hope this helped!

The work in an office takes 150 hours to complete every week. Each person in the office works 32hours a week. What is the smalle
tatiyna

Answer:

5

Step-by-step explanation:

To answer this, we must figure out the minimum amount we can add 32 to itself to reach 150. This means that we must multiply 32 by our desired amount, x, to reach the amount of hours closest to 150 (but above/equal to it). To find x, we can divide 150 by 32, and if it gives us a number with no decimals or remainders, that is x, as it is the smallest amount of people to get above/equal to 150. If it gives us a remainder/decimal, we must round up, as we cannot have a part of a person and we must get the work done, so we must get at least 150 hours. 150/32 is 4.6 something, so we must round up. 5 is our answer

A small rocket is fired from a launchpad 15 m above the ground with an initial velocity left angle 400,450,600 right angle ​m/s.
vivado [14]

Answer:

a)

v=<400, 450+3t, 600-9.81t> m/s

r=<400t, 450t+3t^{2}/2, 15+600t-9.81t^{2}/2> m/s

b) attach file

c) t=122.324s

d) z=18369.9854 m

Step-by-step explanation:

a)

The equation for velocity of each component is v=v_{0}+at, in this case the x-axis component has acceleration 0\frac{m}{s^{2} }, the y-axis component has acceleration 3\frac{m}{s^{2} } and the z-axis component has -g\frac{m}{s^{2} }, where g=9.81\frac{m}{s^{2} }.

The equation for position of each component is  x=x_{0}+v_{0}t+at^{2}/2,

with <x_{0}, y_{0},z_{0}>=<0,0,15>.

c) This time is t when z=0, with positive sign.

d)Solving the equation V_f^{2}=V_o^2 + 2*a*(z-z_{0}) for z, with V_f=0.
