Answer:
7
Step-by-step explanation:
by similarity of traingles Δxuw and Δxyz
xu/xy = uw/yz
given xu+uy=xy and xu=uy
2(xu)=xy
xy=2(uy)
=>5x+4=2(4x-1)
=>5x+4=8x-2
=>3x=6
=>x=2
=>given length of uw=>4x-1=4(2)-1=7
Answer:
110.7989332 percent increase
Step-by-step explanation:
percent increase = (new - original)/ original
the new amount is in 2018 = 363844490
the original amount is in 1950 = 172602624
substitute in
percent increase = (363844490 - 172602624)/ 172602624
percent increase = (191241866)/172602624
percent increase = 1.107989332
multiply by 100 to make a percent from the decimal form
1.107989332*100
110.7989332 percent increase
Answer:
S = v1 t1 = 7 t1 traveling downstream
S = v2 t2 = 5 t2 traveling upstream
7 t1 = 5 t2
7 (6 - t2) = 5 t2 since t1 + t2 = 6
42 - 7 t2 = 5 t2
t2 = 42 / 12 = 3.5 hrs so t1 = 2.5 hrs
S = 7 t1 = 7 * 2.5 = 17.5 mi
Also, S = 5 t2 = 5 * 3.5 = 17.5 mi
