Answer:
$27.70
Step-by-step explanation:
v=video games d=DVDs
7v + 4d =
7(2.3) + 4(2.9) = 27.7
Volume of rectangular prism = 1 1/3 x 5/6 x 2/3 = 4/3 x 5/6 x 2/3 = 20/27
Volume of cube = 1/6 x 1/6 x 1/6 = 1/216
Number of cubes that will pack the rectangular prism = 20/27 / 1/216 = 160
Answer: 20%
100 shares at $45each cost 100*45 = $4500
After a year, he sold the share at the rate if $52 each and it cost 52*100 = 5200
He received dividend of $2 on each dollars meaning 100*2 = $200
So,
$5200+200 = 5400
Profit = $5400 - 4500 = 900
%profit = 900*100 / 4500 = 20
A.
the 2 quantaties are
ricky's distance and greg's distance
it should be total 8 miles
B. ricky distance=ricky rate times ricky time
ricky distance=1.5*3
ricky distance=4.5 miles
ricky distance+greg distance=8
4.5+gdistance=8
minus 4.5 both sides
gdistance=3.5
gdistance=grate time gtime
3.5=2 times time
divide both sides by 2
1.75=time
greg walked 1.75 hour
not sure how to do variable thing and what goes where
ricky walked 4.5 miles
greg walked 1.75 hour and traveled 3.5 miles
