Answer:
5X + 8Y >= 300; intersection at (-20, 50)
Step-by-step explanation:
let t = work hours
0 < t < 30
X = time lawn mowing
Y = time babysitting.
X + Y < 30
5X + 8Y >= 300
We could solve...
X < 30 - Y
5(30 - Y) + 8Y >=300
150 - 5Y + 8Y >= 300
3Y >=150
Y >=50
then X < -20
intersection at (-20, 50)
Answer:
7.6 inches to make an acute triangle
Step-by-step explanation:
a^2+b^2=c^2
7^2+3^2=c^2
49+9=c^2
58=c^2
Square root both sides
c=7.6 inches
Answer:
It's an Irregular Quadrilateral
Step-by-step explanation:
It has 4 sides and the length of the sides of the Quadrilateral is not equal. This makes it irregular.
<u>Collinear points</u>: Three points A, B and C are said to be collinear if they lie on the same straight line.
There points A, B and C will be collinear if AB + BC = AC as is clear from the adjoining figure.
In general, three points A, B and C are <u>collinear if the sum of the lengths of any two line segments among AB, BC and CA is equal to the length of the remaining line segment</u>, that is, either AB + BC = AC or AC +CB = AB or BA + AC = BC.
In other words,
<u>There points A, B and C are collinear if:</u>
(i) AB + BC = AC i.e.,
Or, (ii) AB + AC = BC i.e. ,
Or, AC + BC = AB i.e.,
