V=(1/3)Ah
A=a*b for squares and a*b/2 for right triangles
1)
A=6*8.5=51
V=51*12/3=51*4=204in^3
2)
A=12*6=72
V=72*15/3=72*5=360ft^3
3)
A=18*24/2=18*12=216
V=216*35/3=72*35=2520cm^3
4)
A=26*15/2=13*15=195
V=195*38/3=65*38=2470cm^3
5)
A=B=8ft^2
V=8*12/3=8*4=32ft^3
Answer:
8
Step-by-step explanation: 6.20-4.20=2.00 2.00 divide by 25 for each mile = 8
Answer:
4
Step-by-step explanation:
Need to know #, and solve :
#
is the same as
#you need the same denominator to be able to add or subtract fractions
#
is the same as ![\frac{4}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B6%7D)
#
is the same as a*d = b*c
6 ( 2*s - 4) = 3 ( s+4)
# distribute multiplication over addition and subtraction
12s-24 = 3s+12
#isolate like terms
12s-3s = 12+24
#combine like terms
9s = 36
#divide both sides by 9
s= 4
