3/20, 6/20, 9/20, 12/20 so the common difference is 3/20, ie each term is 3/20 greater than the term preceding it. Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1), a=initial term, d=common difference, n=term number, in this case:
a(n)=3/20+(3/20)(n-1)
a(n)=3/20+3n/20-3/20
a(n)=3n/20 so the 5th term is:
a(4)=3*5/20=15/20=3/4
Answer:760ft2
Step-by-step explanation:
Area of first triangle = 1/2bh = 1/2*8*15=60ft2
Area of second triangle = 60ft2
Area of bottom rectangle =20*15=300ft2
Area of top rectangle = 17*20=340 ft2
Total surface area =60+60+300+340
=760ft2

Answer:
$3.05 i'm pretty sure
Step-by-step explanation:
If one pound is $0.94 and she bought 3.25 pounds you multiply 3 by 0.94 and get $2.82 (we multiply by 3 to make it easier and to deal with the .25 later) then now we deal with the .25, since .25 is 1/4 in fraction just find out what 1/4 of .94 is which is .23 cents. So add $2.82 and $0.23 and you get $3.05
