Answer
the notebooks are 20% of the overall weight due to 70% being textbooks and the other 6 pounds or 30% being the bag and note books and with 2/3 of 30% being 20% then the text books are 13 pounds i used 4 x 3 1/2 but that's just my guess
Step-by-step explanation:
Answer:
A. 9
B. 9.6
C. 38.4
D. 47.4
Step-by-step explanation:
A. Area of the base of the pyramid = length x length
= 3 x 3
= 9
B. Area of one lateral face of the pyramid = area of a triangle
= x base x height
= x 3 x 6.4
= 9.6
Area of one lateral face of the pyramid = 9.6
C. The lateral surface area of the pyramid = 4 x area of one lateral face
= 4 x 9.6
= 38.4
The lateral surface area of the pyramid = 38.4
D. The total surface area of the pyramid = lateral surface area of the pyramid + area of the base
= 38.4 + 9
= 47.4
The total surface area of the pyramid = 47.4

Answer:
Alternate Interior Angles
Step-by-step explanation:
Both angles are on the inside on opposite ends.
For a horizontal line, gradient is zero;
y=mx+c
since m=0
y=c
Replacing for y from given point;
-1=c
c=-1
y-1
