Answer:
40:20
Step-by-step explanation:
2+1=3
so then you divide that by 60 pounds = 20 pounds
you share it:
2x20=40
1x20=20
so its 40:20
you can check it by adding them up as they make 60 so its correct
Answer:
The graph is the correct one
Step-by-step explanation:
A. Plane R and plane P intersect at AB.
Planes are when 3 points that are not on the same line can be used to describe a plane. Plane P is horizontal and Plane R is vertical and these 2 planes intersect at line AB. Intersecting is where these 2 planes meet, therefore line AB is common to both planes.
b. 3 points that are collinear are A, D and B. As the word collinear implies, this is when three points or more are all aligned in a single straight line.
c. Planes can be named indicating three points that are on the same plane yet not on the same line. In other words these points are not collinear. Plane R can be written as DBG or FAD.
d.Coplanar points are three or more points that lie on the same plane. planes are usually flat surfaces, therefore any three or more points lying on this flat surface be used as coplanar points. 4 coplanar points are ACDE, these lie on plane P.
e. A point that lies on both plane P and plane R is point D, as its on the line of intersection, hence its common to both planes.
Answer:
Area of the figure = 36 in²
Step-by-step explanation:
Area of the given composite figure = Area of the rectangle ABCE - Area of triangle CDE
Area of rectangle ABCE = Length × Width
= AB × AC
= 6 × 8
= 48 in²
Area of triangle CDE =
=
= 12 in²
Now area of the composite figure = 48 - 12
= 36 square inch
