Answer:

It will take half of a day

Step-by-step explanation:

Since 12.5 is roughly half of the day, no matter what temperature is, it will take you this amount of time. You also need to include the time that you will use to take breaks and eat meals.

Slope of (-20,9) (14,9)
skelet666 [1.2K]
Y2-y1/x2-x1 is slope so

9-9/14-(-20) so you get 0/34 which means there is no slope since they have the same y (the equation would be y=0x+9 therefore y=9)
Which makes sense since the equation is a straight line

What is the answer to this?
amm1812

Answer:

<h2>40.1 cm</h2>

solution,

BC=8.4 cm

AB=12 cm

BD=4.1 cm

We have to find out: AC ,CD

using Pythagoras theorem:

In ∆ABC ,<B=90°

{(ac)}^{2}  =  {(ab)}^{2}  +  {(bc)}^{2} \\  {(ac)}^{2}   =  {(12)}^{2}  +  {(8.4)}^{2}  \\  {(ac)}^{2}  = 144 + 70.56 \\  {(ac)}^{2}  = 214.56 \\ ac =  \sqrt{214.56}  \\ ac = 14.64 \: cm

Similarly,

In ∆BCD, CB=90

cd =   \sqrt{ {(8.4)}^{2} +  {(4.1)}^{2}  }

=  \sqrt{70.56 + 16.81}  \\  =  \sqrt{87.37}  \\  = 9.34 \: cm

Perimeter:

AC+CD+AD

=14.64+9.34+(12+4.1)

=40.08

= 40.1 cm

Hope this helps...

Good luck on your assignment..
