Answer:
2). Volume = 14400 feet³
3). Volume = 157.5 ft³
Step-by-step explanation:
Both the figures given in the sheet attached are a rectangular pyramid and a triangular prism.
2). In this part of the question solid given is in the shape of an rectangular pyramid.
Volume of this oblique pyramid = 
Here 'B' = area of the base
h = height of the pyramid
Volume = 
= 14400 cubic feet
4). Volume of a triangular cone = (Area of the triangular base)×(height)
= ![[\frac{1}{2}(\text{Base})(\text{height})]\times {\text{height of the prism}}](https://tex.z-dn.net/?f=%5B%5Cfrac%7B1%7D%7B2%7D%28%5Ctext%7BBase%7D%29%28%5Ctext%7Bheight%7D%29%5D%5Ctimes%20%7B%5Ctext%7Bheight%20of%20the%20prism%7D%7D)
= 
= 157.5 ft³
Answer: 3 packets
12/2 = 6 seeds per packets
18/6 = 3 packets
The residuals are the numbers shown next to each black line. Just total them:
15 + 10 + 11-10 +9 +10 +3-17-12 = 19.
The answer is B. 19
Answer:
y = 5 and x = -3
Step-by-step explanation:
Given,
y = x + 8 ...............( equation 1 )
x + y = 2 ...............( equation 2 )
Now, by substituting the value of y in equation 2, we get;
⇒ x + x + 8 = 2
⇒ x = -3
and now, by substituting the value of x in equation 1, we get;
⇒ y = -3 + 8
⇒ y = 5
