Answer:
14.7cm^3
Step-by-step explanation:
The volume formula for a pyramid is l·w·h/3 or BH/3
The base of the height is 6.9 and the height is 6.4
(6.9)(6.4)=44.16
44.16/3=14.72
14.72 rounded to the nearest tenth is 14.7cm^3
Hope this helps! :)
Answer:
n = -31.5
Step-by-step explanation:
let 'n' = the number
n/-1.5 = 21
to solve for 'n', multiply each side by -1.5 to get:
n = -31.5
Use dot product
a=(x1,y1) and b=(x2,y2)
a.b=/a/*/b/ cos x
a.b mean dot product of two vectors
a.b is equals x1*y1+x2*y2
