3+5+7=15
15 units
33ft 9in =15 units
convert to feet
33ft=12in times 33=396in
396+9=405
405in=15units
divide both sides by 15
27=1unit
p=3units
p=3*27
p=81 inches=6ft 9in
q=5 units
q=5*27
q=135 inches=11ft 3in
r=7units
r=7*27
r=189 inches=15ft 9in
p=6ft 9in
q=11ft 3in
r=15ft 9in
13/52 is the ratio of hearts to all cards
That reduces to a 1/4 ratio
or a 25% chance of drawing a heart
Given:
Area(A)= 63m^2
Length (L)= 2W+5
Width (W)=?
A=LxW
63=(2W+5)(W)
63=2W^2 + 5W
0=2W^2+5W-63
0=(2W-9)(W+7)
2W-9=0 then W=4.5 and W+7=0 then W=-7
Can only use 4.5 since it is positive and distance is positive.
W= 4.5 m
L=2W+5=2 (4.5)+5=9+5=14m
