Answer:
16
Step-by-step explanation:
5+5=10
3.5+2.5=6
10+6=16
Can I have brainiest?
Well, the formula for a triangle is base times height times 1/2. In this case it would be 21x30. That equals 630. Then, you divide 630 by 2 which is 315. Your answer would be 315 squared.
18.24 pounds on each shelf because the weight divided by the amount of bags would be .96 pounds per bag. And then the total amount of bags divided by the amount of shelves would be 19 so 19x.96 pounds is 18.24 on each shelf

Triangle
prism
a triangular end with a base of 27 mm and a height of 23 mm.
the length of each side is 56 mm and the width of each side
is 27 mm
SA=bh+(s1+s2+s3)H
SA=(27)(23)+(27+27+27)(56)
SA= 621 + 4536
SA=5157 mm^2
V = ½ blh
V = ½ (27)(23)(56)
<span>V = 17388 mm^3</span>

Cone
SA = πr(r + √(h^2 + r^2) (r = 4, h = 7)
SA = 4π (4 + √(7^2 + 4^2))
SA = 4π (4 + √(49 + 16))
SA = 4π (4 + √65 )
SA = 16π + 4√65
V = 1/3 πr^2h (r = 4, h = 7)
V = 1/3 π (4^2)(7)
V = 112/3 π
V = 37 1/3 π
