Answer:
I don't understand who would be charged less money cause it's just the parents and the child and the child is only paying them from the hours being on the phone. but from what I know 90÷ 3 is 30. so the parents would be making like $30 but if its multiplication 90×3 is like 270

<h2><u>Question</u><u>:</u><u>-</u></h2>
ricky is a hardworking man who owns 6 hectares of land. in his will,he divided his lot equally among 7 sons. how much land will each of his son receive?
a. 0.68
b. 0.86
c. 68
d. 86
<h2><u>Answer</u><u>:</u><u>-</u></h2>
<h3>
Given,</h3>
Land owned by Ricky = 6 hectares
No. of sons = 7
<h3>Now,</h3>
6 ÷ 7 = 0.8571429 or 0.86
<em>→</em><em> </em><em>Each</em><em> </em><em>son</em><em> </em><em>will</em><em> </em><em>own </em><em>0</em><em>.</em><em>8</em><em>6</em><em> </em><em>hectares</em><em> </em><em>of </em><em>land.</em><em> </em><em>Option</em><em> </em><em>b.</em><em> </em><em>0</em><em>.</em><em>8</em><em>6</em><em> </em><em>is</em><em> the</em><em> answer</em><em>.</em>

Step-by-step explanation:
Since Point A is included in the altitude, we must have an equation that has to make Point A a solution set in the equation.
Pluging in and chugging Point A into each equation should tell us what the equation should be.
<u>Option 1</u>
x - y = 1
-3 - 2 = 1
-5 ≠ 1
We see here that -5 does not equal to 1. Therefore option 1 is incorrect.
<u>Option 2</u>
x + y = -1
-3 + 2 = -1
-1 = -1
We see here that -1 does equal to -1. Therefore option 2 is correct.
<u>Option 3</u>
x + y = 1
-3 + 2 = 1
-1 ≠ 1
We see here that -1 does not equal to 1. Therefore option 3 is incorrect.
<u>Option 4</u>
x - y = -1
-3 - 2 = -1
-5 ≠ -1
We see here that -5 does not equal to 1. Therefore option 4 is incorrect.
We can also graph the points and eyeball it. Doing so, we should see that our y-intercept is around -1 and our slope is also negative. Option 2 would be the best fit.
In this question, there are 4 consolation door and 2 car doors of total 6 doors. That means for the first door the chance to get consolation is 4/6 and car is 2/6. In second door, only 5 remains so the chance to get consolation is either 4/5 (if 1st door car) or 3/5(if 1st door consolation)
Win 1 car condition:
1. 1st door car, 2nd door consolation = 2/6 * 4/5 =8/30
2. 1st door consolation, 2nd door car= 4/6 * 2/5 = 8/30
8/30+8/30= 16/30
No car condition
1. 1st door consolation, 2nd door consolation= 4/6 * 3/5= 12/30
At least one car condition
1. 1st door car, 2nd door car = 2/6 * 1/5 =2/30
2. 1st door car, 2nd door consolation = 2/6 * 4/5 =8/30
3. 1st door consolation, 2nd door car= 4/6 * 2/5 = 8/30
2/30 + 8/30 + 8/30= 18/30
