Answer:

Step-by-step explanation:
1) the rule of transformation [degr → rad] is:
![\alpha [rad]=\alpha [degr] *\frac{\pi }{180};](https://tex.z-dn.net/?f=%5Calpha%20%5Brad%5D%3D%5Calpha%20%5Bdegr%5D%20%2A%5Cfrac%7B%5Cpi%20%7D%7B180%7D%3B)
2) according to the formula above:
230°=230*π/180=23π/18 [rad].
Answer: in explanation
Step-by-step explanation
Sandi can perform 1/9 of the task in a day
Eva can perform 1/5 of the task in a day
Working together, they can perform
1/9 + 1/5 of the task per day
= 5/45 + 9/45 = 14/45 of the task in a day
or 45/14 days in the task = 3.2 days
So
It would take about 3.2 days to complete the task working togethe
Answer:
x = 4
Step-by-step explanation:
<u>Step 1: Set both parts equal to 0</u>
x - 4 = 0 and x - 4 = 0
<u>Step 2: Solve for x by adding 4 to both sides</u>
x - 4 + 4 = 0 + 4 and x - 4 + 4 = 0 + 4
x = 4 and x = 4
Answer: x = 4
